Background: The aim was to compare the differences in feelings of hunger and satiety in a group of overweight/obese women after eating a test meal with or without bread. Patients and methods: The study included 122 women (BMI >= 25 < 40 kg/m²) who were randomly assigned to consume one of the following test meals: NO BREAD meal (2.40 MJ, 46% carbohydrates, 26% protein, 28% fat; which included rice or pasta) and BREAD meal (2.39 MJ, with equal caloric distribution and the same foods except with bread instead of rice or pasta). A visual analogue scale (VAS) was used, with 5 questions to be answered at different times: 1) just before eating, 2) just after eating and exactly 3) 60 and 4) 90 minutes after eating the test meal. The test was performed at the start and after 16 weeks of following a lifestyle modification program based on a low-calorie diet (with or without bread). Results: 104 women completed the study (48.4 ± 9.0 years) with a baseline BMI of 29.8 ± 3.5 kg/m². At the start of the study there were no significant differences in any of the VAS parameters measured between the groups. After 16 weeks, BREAD group obtained higher scores in question 3 (referring to the sensation of satiety) that were significant at time 3 (7 versus 5; p < 0.05) and time 4 (8 versus 4; p < 0.01). Conclusions: The inclusion of bread in a low-calorie meal may result in a greater sensation of satiety after eating. These results contradict the recommendation to exclude bread from a food plan aimed at weight loss. [ABSTRACT FROM AUTHOR]

Background and objectives: The aim of this study was to describe the hormonal and inflammatory status of a group of overweight/obese women. Patients and methods: The sample studied was a crosssectional cohort of women > 18 years of age, BMI >= 25 < 40 kg/m², prior to starting a weight control program. Data collected were: demographic characteristics, blood pressure, anthropometric parameters, physical activity data, and biochemical, hormonal and inflammatory biomarkers. Results: The study involved 104 women with a mean age of 48.4 ± 9 years and a BMI of 29.8 ± 3.5 kg/m². Some 48% of the women studied were in menopause. Some 8.9% had hyperinsulinemia. The mean ghrelin value was 38.8 ± 33.6 pg/ml; there was no correlation between ghrelin levels and anthropometric and biochemical variables. CRP, leptin, adiponectin, resistin, IL6, IL10, and PAI1 were 3.0 ± 2.7 mg/dl, 36.3 ± 19.5 ng/ml, 8.3 ± 4.5 mg/ml, 24.3 ± 23.2 ng/ml, 51.6 ± 93.6 pg/ml, 10.0 ± 34.2 pg/ml and 22.3 ± 30.6 ng/ml, respectively. Obese patients had significantly higher mean values of resistin and PAI 1 than those who were overweight. These levels correlated significantly with anthropometric and biochemical variables; however, the correlations were weak. Age, menopause or the regular practice of physical activity had no effect on mean values. Conclusions: The group of women studied had altered inflammatory biomarkers in relation to people of normal weight. The study shows the inflammatory status of overweight/ obese individuals, and the values obtained may help to establish standard ranges for these markers. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Nutrition labelling (NL) provides information on the energy and nutrients in a food and it represents a valuable tool to help consumers make informed decisions about their diet and lifestyle. However, little is known about how consumers perceive the nutrition labelling information. OBJECTIVES: Evaluate the knowledge of NL of a population survey and examine aspects such as attention, reading, understanding and utility. MATERIAL AND METHODS: 200 volunteers were interviewed about NL on National Nutrition Day (NND) on May 28, 2010 at the La Paz University Hospital in Madrid. The questionnaire was self-administered and this contained 10 closed multiple choice questions. RESULTS: The surveyed group (66.7% women and 33.3% men) had a mean age of 42.0 ± 15 years and a BMI of 24.1 ± 3.8 kg/m². A percentage of 86.5% had completed secondary and higher education. The concept about NL was knocked by 77.1% of them. This percentage was significantly higher according to the level of their studies (primary 7.1%, secondary 32.1% and higher studies 60.9%; p < 0.0001) and also regarding the age range (42.3% vs. 25% of over that 50, p < 0.05). 73.8% always or almost always readied NL; 67.7% of those who declared that always readied were women and 71% had higher education. 53.8% of people over 50 years were not capable of reading labels due to the small letters. The most interesting information for the consumers was: calories (61%), fats (39%) and cholesterol (25.7%). Nutritional concepts questions had a low percentage of right answers, especially in volunteers with lower level of education and among older age groups. CONCLUSIONS: Results show that consumers have a low level of nutrition information that would enable a better choice to purchase food. Nutrition education is needed should be necessary to NL had a significant impact on the foods election. Therefore, this fact could contribute to the maintenance of health and disease prevention.

Introduction: As eating disorders include both psychological and physiological components, appropriate management of these disorders requires input from a number of disciplines working together in a coordinated manner, following an integrated Programme. The Eating Disorders-Nutrition Education Programme has as its purpose achieving healthier habits and modifying eating behaviour. The Programme should take place as one part of Eating Disorders treatment. Objectives: To determine the efficacy of a Nutrition Education Programme about nutritional state and eating patterns in a group of patients diagnosed with Eating Disorders who follow the usual check-up protocol in the clinic for nutrition and mental health. Material and methods: 89 patients were included, including 5% men. They received individual nutritional education with weekly/fortnightly appointments during a period of 4-6 months. Educational counseling was carried out by a dietician. The mean age of the sample was 24 +/- 8 years and the diagnoses were: Anorexia Nervosa Restrictive (ANR) 32.5% Anorexia Nervosa Purgative (ANP) 26.5%, Bulimia Nervosa (BN) 18%, Eating Disorder Not Otherwise Specified (EDNOS) 21% and Binge Eating Disorder (BED) 2%. The average evolution time since the diagnosis was 4.8 +/- 5 years. An anthropometric assessment, assessment of daily oral intake, 24-hour dietary recall, and Eating Attitudes Test (EAT26) questionnaires were completed at the first appointment and again at the end of the programme. Results: The mean score of the EAT26 questionnaire was 32 +/- 15 initially, and after 4-6 months the score was 23.7 +/- 14 (p < 0.001). This change represents a significant improvement in the patients' symptoms after the Programme. Furthermore there were significant differences in the evaluation of the questionnaire by scales and by diagnosis. After 4-6 months, there was a meaningful reduction in episodes of vomiting per week (from 7.5 +/- 10 to 1 +/- 1.8 p < 0.001) in ANP and BN binge-purging (8 +/- 9.7 vs 2.2 +/- 3.2 p < 0,01). In addition, a favourable trend in the number of binges per week was observed for both diagnoses. The percentage of subjects that ate less than 4 meals per day decreased from 70% to 19% after the Education Programme (p < 0.001). Some 67% of the patients dedicated a specific time for eating and a 54% started to have complete meals. These results that show a very favourable tendency with respect to the normalization of eating patterns. There was improvement in the intake of dairy products, vegetables, fruits, cereals and oil (p < 0.05). At the beginning, 34% consumed at least 3 of the 6 food groups within the recommended range, but at the end 70% did (p < 0.001). After the nutritional education programme, an important increase in energy ingestion and carbonhydrate consumption took place (p < 0.001), as much with ANR as with ANP. With respect to micronutrients, the ingestion of vitamin B2 significantly increased, as well as folic acid and calcium (p < 0.001) in ANP, and magnesium and calcium (p < 0.001) in ANR. In ANR, we found a significant improvement in nutritional status (p < 0.001). Variables including weight, BMI, muscular circumference of the arm and tricipetal fold were at the limit of significance. Regarding ANP and EDNOS, the initial evaluation demonstrated that they were within normal limits, and they were maintained after nutritional education. In BN, progress towards normalization of BMI took place, increasing from 26.4 +/- 6.6 to 25.5 +/- 5.7 (-2.3 kg). Conclusions: The Nutritional Education Programme carried out by qualified professionals should be a part of Eating Disorders treatment, along with medical and psychological monitoring and as part of an interdisciplinary, multiprofessional team effort.

The modification of dietary patterns has led to a change in fatty acid consumption, with an increase in the consumption of ω-6 fatty acids and a marked reduction in the consumption of ω-3 fatty acids. This in turn has given rise to an imbalance in the ω-6/ω-3 ratio, which is now very different from the original 1:1 ratio of humans in the past. Given the involvement of ω-6 and ω-3 essential fatty acids in disease processes, the present article examines changes in dietary patterns that have led to the present reduction in the consumption of ω-3 essential fatty acids, and to study the importance of the ω-6/ω-3 balance in maintaining good health. In addition, an assessment is made of the established recommendations for preventing a poor intake of ω-3 essential fatty acids, and the possible options for compensating the lack of these fatty acids in the diet.

Introduction: Oncohematologic patients usually present nutritional deficits associated with the disease, the treatments and side effects, etc. However, there are hardly any descriptive data about the dietary recommendations used and the patient's self-perception of its usefulness in their disease. Aim: To assess the self-perception of the nutritional importance in a group of oncohematologic patients. Materials and methods: 111 oncohematologic patients self-reported a questionnaire containing items about socio-sanitary data and self-perception of the nutritional importance in their disease. Results: The mean age was 40.0 ± 12.8 years (64.86% women). The most frequent diagnosis and treatment was lymphoma (83.78%) and chemoteraphy (92.80%). 75% considered 'very important' relationship between oncohematologic disease and nutritional status. Only 54.1% received dietary advice. And 53.2% and 50.5% consideredthat the use of nutritional supplements improve quality of life and/or disease respectively. Conclusions: A significant percentage of patients had advanced stages of their disease. However, half the group had not received dietary advice despite high interest in receiving nutritional care. Therefore, the nutritional assessment and the personalized nutritional support implementation of the patient should be included in routine clinical practice. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lifestyle intervention is fundamental for obesity treatment. The aim of this study was to evaluate the effects of a program focused on diet, exercise and psychological support on Lifestyle Modification in overweight and obese patients treated in Primary Health Care setting. METHODS: 60 patients with grade II overweight and non-morbid grade I-II obesity were included in this pilot clinical trial. Ages ranged from 18 to 50 years. They were provided with a program combining nutritional education, physical activity and psychological support. Subjects attended group sessions every 2 weeks. The main outcome measures at baseline and 6 months were body composition parameters (BMI, body fat percentage, waist circumference) and lifestyle intervention using the Questionnaire for the assessment of overweight and obesity related lifestyles at baseline and six months. This questionnaire yields an five dimensions: diet caloric intake (CC), healthy eating (AS), physical activity (EF), searching for psychological well-being eating (BP) and alcohol intake (CA). The higher score indicates better lifestyles for CC, AS, EF and worse for BP y CA. RESULTS: At the end of the intervention the program achieved improvements in Questionnaire related lifestyles subscales: CC (2,60 ± 0,5 vs. 3,49 ± 0,7, p<0,001), EF (2,19 ± 0,9 vs. 3,17 ± 1,0, p<0,001) and AS (3,04 ± 0,4 vs. 3,43 ± 0,4, p<0,05); CA (3,98 ± 0,7 vs. 4,25 ± 0,7, p<0,05) and BP (2,82 ± 1,0 vs. 3,34 ± 0,7, p<0,001) has got worse. CONCLUSION: The Program focused on balanced and moderate energy-restricted diets, increased physical activity and psychological support may improve the anthropometric parameters and the Lifestyle intervention in obese patients treated in a primary healthcare center.

Background and objectives: The beneficial effect of eicosapentaenoic acid in cancer patients is widely described especially in relation to its role in tumour cachexia. The aim of the study was to evaluate the efficacy of administration of a new oral powder supplement enriched with eicosapentaenoic acid compared to a standard liquid supplement in cancer patients. Patients and methods: A total of 61 cancer patients, aged more than 18 years, were randomized to receive during a month a bonus of 600 kcal/ day to their regular diet with an oral powder supplement enriched with eicosapentaenoic acid (1.5 g) (RSI) or with a standard liquid supplement (RE). The following data were collected at baseline and after one month: the Patient-Generated Subjective Global Assessment (pg-SGA), anthropometric measurements (skin folds, circumferences and bioimpedance), dietary parameters (3-day food record), biochemical and inflammatory parameters (basic biochemistry, cytokines, prealbumin and Reactive C Protein). Quality of life was evaluated using the SF-36 questionnaire. At the end, scales were used to asses sensory perception, tolerance and satiety induced by the products and motivation to eat. Results: 40 patients completed the study. After intervention, anthropometric parameters do not change and prealbumin values increased significantly in both groups (RSI 16.11 ± 5.66 mg/dl vs. 19.81 ± 6.75 mg/dl p < 0.05 and RE 6.13 ± 16.55 mg/dl vs. 19.03 ± 5.47 mg / dl p < 0.05). RSI group significantly decreased interferon gamma (INF-[gamma]) values (0.99 ± 0.95 vs. 0.65 ± 0.92 pg/ml, p < 0.05). In contrast, RE group increased INF-[gamma] after intervention (1.62 ± 1 27 vs. 2.2 ± 3.19 pg/ml, p < 0.05). There were no significant differences in hunger, appetite, satiety and intake capacity in both groups. The SF-36 scores improved in both groups. Conclusions: Supplementation based on an oral powder formula enriched with 1.5g EPA during one month in cancer patients improved certain inflammatory parameters. This product may be a novel and valuable option to be added to the nutritional intervention strategies used for cancer patients. [ABSTRACT FROM AUTHOR]

Introduction: Obesity has become a serious health problem. It is nowadays considered a pandemia and it is therefore a priority to develop different strategies on its prevention and treatment: lifestyle changes, community interventions as well as pharmacological and non-pharmacological activities. In this way, meal replacement products (energy reduced products designed to replace one or two regular meals providing a supously nutritionally balanced low fat meal) can be an alternative to traditional reduced calorie diet. Objective: Our aim was to revise the literature on meal replacement and compare the nutritional composition and the different forms of presentation of the main meal replacement products commercialised in Spain. Methodology: We made a research in pharmacies, weight loss centers and big supermarkets of food products specially designed to replace a meal. We compared the nutritional composition regarding macronutrients and micronutrients of the thirty-two different products founded, including their different form of presentation (bars, powder, drink-shakes and crackers). In order to judge their nutritional composition, we compared one meal replaced with these products with the Recommended Dietary Allowances (RDA). Results: The most common form of meal replacement products were bars (23 of 32 analyzed products), followed by powder for making shakes (6 products), bricks (2 products) and crackers (1 product). When we analysed a single meal replaced with these products, we founded that the global distribution of macronutrients was: 45% as carbohydrates, 29% as fats, 26% as proteins, and 4.45 grams of fiber. Their average energy was 266 Kcal per meal. Regarding micronutrients (vitamins and minerals), there was a great variability among the different products, but in average their composition was above the 33% of the RDA per meal specially in iron and vitamins B1, B6 and D. Calcium, magnesium, folic acid and vitamin B12 were the micronutrients less plentiful. Conclusion: Partial meal replacement can be an alternative or a complementary therapeutic option to conventional hipocaloric diets in obesity since they appear to have an easier understanding and follow up. It is therefore important to consider them in weight management programs and more studies are required to establish strict criteria on their nutritional composition by a legal normative.

INTRODUCTION: Knowing the opinion of oncologic patients about the importance they give to their feeding, the difficulties they have with feeding, their body image, weight, and ponderal changes, the relationship between their feeding and their illness, the relationship between their physical activity and their mood and health is essential to look for nutritional therapeutic interventions leading to improvement of quality of life and, in general, the feeling of well being. Thus, it is paramount to know the patients' opinion of these issues. MATERIAL AND METHODS: We passed a questionnaire to 131 patients. The patients were recruited from the Day-Hospital of the Medical Oncology and Radiotherapeutic Oncology Departments, and from the Hospitalization Department of Medical Oncology. In the questionnaire, we asked in a simple manner about the importance the patients give to all these issues. This is a 20-item questionnaire, divided into six parts: 1. Vital statistics; 2) perception about the disease and its relationship with feeding; 3) Perception of the relationship between physical activity and mood with feeding; 4) Nutritional therapies prescribed to the patients and their perception on its effect on the disease progression; 5) Current difficulties with feeding; 6) Demand of nutritional care. RESULTS: The patients mean age was 57 +/- 13 years. 45% were males, and the remaining females. 81% life in an urban area, and only 14% in a rural area. The educational level was categorized in 5 groups: without education, basic education, elementary school, high school, or college studies. 28% had basic education, and 19% college studies, and only 8% had no education at all. Their occupation was also categorized in five groups: home-keeping, student, unemployed, employed, and retired. 33% were employed, 29% retired, and 34% were home-keepers. Most of the patients (74%) are aware of their illness and perceive it as severe or very much severe. Most of these patients worry about their body image, weight, and ponderal changes, and they relate them with their feeding status. 74% find a relationship between their nutritional status and their physical activity, and 73% relate it with their mood. At least half of the patients perceive their mood as being low. Although 47% manifested having some difficulty for feeding, only 34% had received some information about their diet, 26% had consumed nutritional supplements, and 81% still consumed their diet without any change. The most common difficulties for feeding were decreased appetite (38%), early satiety (32%), and nausea (20%). The nutritional intervention most commonly required by the patients was general and specific nutritional education to alleviate the symptoms associated to oncologic therapies. CONCLUSIONS: Most of the patients are aware of the severity of their illness and care about their body image, weight, and ponderal changes, which they associate with their nutrition. Most of the patients find a close relationship between their nutritional status, their physical activity and their mood. More than half of the patients manifest having some difficulty feeding, but only one third of the population has received information about their diet some time. It is clearly shown that oncologic patients need different effective nutritional intervention measures contributing to improve their feeling of well being. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Cancer and its oncological treatment cause symptoms which increase the patients risk to suffer from malnutrition. This affects the patients health status negatively by increasing the number of complications, reducing the tolerance to the oncology treatment and a decrease of the patients quality of life. Motivated by this, a group of health professionals from several spanish regions met with the backing of the Sociedad Española de Nutrición Básica y Aplicada (SENBA) to address strategies to improve the quality of nutritional intervention in cancer patients. METHODS: This multidisciplinary group developed a protocol describing nutritional assessment and intervention in form of algorithms based on literature and personal experience. The patients are classified in a three step process: 1. type of their oncology treatment (curative or palliative); 2. nutritional risk of the antineoplastic therapy (low, medium or high risk) and 3. depending on the Subjective Global Assessment patient-generated (SGA-pg). The patients are classified as: A. patients with adequate nutritional state, B. patients with malnutrition or risk of malnutrition and C. patients suffering from severe malnutrition. During one year, the protocol has been used for 226 randomly chosen female and male patients older than 18 years. They were treated by the Medical and Radiotherapy Oncology outpatient clinic. RESULTS: More than a half of the patients were suffering from malnutrition (64%) increasing up to 81% for patients undergoing palliative treatment. Most of them were treated curatively (83%) and received oncology treatment with moderate or high nutritional risk (69%). 68% of patients were affected by some feeding difficulty. The mean percentage of weight loss has been 6.64% +/- 0.87 (min 0%, max 33%). Albumin values of 32% of the patients were between 3 and 3.5 g/dl and negatively correlated with feeding difficulties (p = 0.001). The body mass index (BMI) has not found to be a significant parameter for detecting malnutrition (only in 10% of the patients, the value was below 19.9 kg/m2). But a significant linear tendency when compared to feeding problems could be shown, such that in patients with less feeding problems a higher BMI has been found (p = 0.001). More than a half of the patients required nutritional counselling to control symptoms which made food intake difficult. One third of the patients needed oral nutritional supplementation. Following the nutritional intervention the weight of about 60% of the patients could be maintained and of one sixth it could be increased. CONCLUSION: The application of this protocol is useful, easy and could help detecting malnutrition in oncology patients. It provides the possibility to select those patients who can benefit from a specific nutritional intervention. If possible, the application of the protocol should be started immediatly after cancer is diagnosed. Nutritional support proves efficient for most of the patients. [ABSTRACT FROM AUTHOR]

Interest in the relationship between diet and cognitive function has increased in recent years. In this sense, eggs contain many essential nutrients that are also beneficial for cognitive function. Several studies have shown that moderate egg consumption not only does not increase cardiovascular risk but is positively associated with better cognitive performance and a lower risk of dementia. Egg protein is particularly rich in tryptophan, which is a precursor to serotonin, the neurotransmitter involved in mood, and melatonin, the hormone that regulates the sleep-wake cycle. Consumption of tryptophan-rich egg hydrolysates has been associated with improved attention and reduced feelings of sadness or depression. Egg choline is needed for the synthesis of acetylcholine, the neurotransmitter involved in memory and learning, and also for the synthesis of phosphatidylcholine, the intake of which has been linked to better mental function and a lower risk of dementia in adults. Choline intake during pregnancy reduces the risk of neural tube defects and is associated with better offspring development. And lutein and zeaxanthin, which are particularly concentrated in the nervous system, are associated with better visual function and cognitive development in the offspring and also in the elderly. All this evidence confirms the importance of including eggs in a balanced diet to prevent cognitive decline and improve cognitive health throughout life.

Obesity is a major public health challenge, in Spain the prevalence of excess of weight and obesity and is 56 % and 19 %, respectively, and it is linked to numerous preventable chronic diseases. Nutritional epidemiology focused on nutrients has evolved towards the study of dietary patterns that consider synergistic interactions between foods and nutrients. This study aims to investigate the relationship between obesity and its treatment by healthy dietary patterns. The Mediterranean diet and Dietary Approaches to Stop Hypertension (DASH), based on plant products, whole grains and low levels of salt, sugars and red meat, have been shown to promote weight loss and reduce comorbidities associated with obesity. Although vegetarian and vegan diets are adequate options for disease management and prevention, they require planning to avoid nutritional deficiencies. In conclusion, healthy dietary patterns such as the Mediterranean diet, DASH and vegetarian options are effective in both the prevention and treatment of obesity, highlighting the importance of considering the synergy between foods and nutrients in the management of this health condition.

Yogurt has been valued very positively for centuries, but the concern for food sustainability and the fact that it is a food of animal origin has raised doubts about the consumption that may be convenient. The objective of this work is to deepen the topic and establish recommendations for the population. From the nutritional point of view, yogurt is a valuable food, for its high content, quality and bioavailability of its nutrients, in a low energy content, its components together with probiotic microorganisms are provided in a matrix that helps achieve greater nutritional and health benefit. Regular consumption of yogurt has been linked to cardiovascular protection, against diabetes, excess weight, cancer, bone health. Thinking about environmental sustainability, yogurt production is not particularly dangerous, as the kg of CO2 eq (greenhouse gases) associated with their production are the lowest obtained compared to other animal foods and even lower than those associated with the production of some plant foods and the supply of nutrients per 1000 kcal, per 100 g, or per euro is one of the highest available. There is the possibility to further improve sustainability with improvements in animal feed, packaging, transport, etc. Considering this evidence, the daily consumption of yogurt / fermented milk should be included in the food guidelines, not only as one more milk option, but specifying a specific consumption such as a ration / day, this pattern can be useful from the nutritional point of view and for the improvement of public health.

Objectives: Innovative precision dietary procedures are required to promote healthy aging. This study aimed to evaluate the effects of a personalised strategy based on the inclusion of individualised foods and digital tools on overall health status and quality of life within a follow-up of 3 months in older adults with overweight or obesity., Methods: 127 men and women aged between 50 and 80 years with overweight/obesity participated in the study-between January 2020 and September 2020 at the Center for Nutrition Research-University of Navarra and IMDEA-ALIMENTACIÓN-and were randomly assigned to a usual-care group (standard recommendations) or precision group (precision nutrition strategy based on the inclusion of individualised foods and a mobile application). Anthropometry, body fat percentage, biochemical parameters, diet, and quality of life (SF-36 Health Survey) were assessed at baseline and after 3 months., Results: Both strategies were found to improve overall metabolic health; however, the precision approach demonstrated significantly better outcomes. The precision strategy reduced body weight at 3 months (-4.3 kg; p < 0.001) with significant improvements in body fat percentage, blood pressure and general metabolic health (glycated haemoglobin; alanine aminotransferase; aspartate aminotransferase; hepatic steatosis index) in comparison with the standard recommendations. The precision approach significantly enhanced the quality of life (SF-36) of individuals, with additional improvements in emotional well-being (p = 0.024) and vitality (p = 0.008). Adherence to the Mediterranean diet was significantly associated with a higher quality of life and vitality., Conclusion: These results support the benefit of precision nutrition approaches for promoting healthy aging and emotional well-being, enhancing the quality of life in aging populations, during the COVID-19 pandemic., (Copyright © 2024 The Authors.

Background: Childhood overweight and obesity is a global concern and has increased in Spain over the last decades. Combinations of lifestyle behaviors (i.e., diet, sleep, and sedentarism) are highly related to weight status. Therefore, this study aimed to identify lifestyle patterns among children from Madrid City, and analyze associations with the prevalence of overweight, obesity, and abdominal obesity, considering socio-economic factors., Methods: A cross-sectional analysis was conducted on 4545 children from the ENPIMAD study with data on diet, sleep, anthropometric, and socio-economic variables. K-means cluster analysis was used to identify lifestyle clusters, and logistic regressions were used to examine the associations between socio-economic indicators and cluster membership, and between clusters and weight status., Results: Findings show three lifestyle clusters (healthy, mixed, and unhealthy), with boys and older children more represented in the unhealthy cluster. Food insecurity and low socio-economic status were associated with unhealthier clusters in boys and girls. Children in unhealthier clusters were more likely to have obesity and abdominal obesity. However, these associations disappeared in girls after controlling for food insecurity., Conclusion: These results provide insight into the combination of behaviors and socio-economic factors associated with childhood obesity that may aid in the design of future interventions.

Proteins are macronutrients with multiple health benefits, but excessive consumption can negatively affect health. This study aimed to evaluate the characteristics of a sample of high-protein processed foods (HPPFs), describe how their consumption affects dietary balance, and acquire knowledge of the consumption patterns of these products in a Spanish population. A sample of HPPFs available in supermarkets and on websites was collected. The contribution to recommended protein intakes was calculated using national and international references and considering the single consumption of the HPPFs and the product plus 150 g of meat. Furthermore, an online survey was conducted among a convenience sample. A total of 36 enriched protein products were evaluated. The percentage of proteins in these products ranges from 10 to 88%. The contribution of the protein recommended intake was within a range of 87.4-306.6% and 66.4-232.8% (women and men, respectively), only considering the additional proteins from 150 g of meat. One hundred thirty-nine participants completed the survey; 67.6% affirmed that they had consumed HPPFs, and half consumed them without following any consumption control. Since these products are accessible to everyone in supermarkets and protein intake is generally higher than the recommended limits, regulating the mass sale of HPPFs is essential to ensure they do not lead to protein overconsumption.

Introduction: Anorexia nervosa (AN) is a multifactorial disorder. A possible role of the social network and the gut microbiota in pathogenesis has been added. Exogenous shocks such as the COVID19 pandemic have had a negative impact on patients with AN. The potential medical and nutritional impact of malnutrition and/or compensatory behaviors gives rise to a complex disease with a wide range of severity, the management of which requires a multidisciplinary team with a high level of subject matter expertise. Coordination between levels of care is necessary as well as understanding how to transition the patient from pediatric to adult care is essential. A proper clinical evaluation can detect possible complications, as well as establish the organic risk of the patient. This allows caregivers to tailor the medical-nutritional treatment for each patient. Reestablishing adequate nutritional behaviors is a fundamental pillar of treatment in AN. The design of a personalized nutritional treatment and education program is necessary for this purpose. Depending on the clinical severity, artificial nutrition may be necessary. Although the decision regarding the level of care necessary at diagnosis or during follow-up depends on a number of factors (awareness of the disease, medical stability, complications, suicidal risk, outpatient treatment failure, psychosocial context, etc.), outpatient treatment is the most frequent and most preferred choice. However, more intensive care (total or partial hospitalization) may be necessary in certain cases. In severely malnourished patients, the appearance of refeeding syndrome should be prevented during renourishment. The presence of AN in certain situations (pregnancy, vegetarianism, type 1 diabetes mellitus) requires specific care. Physical activity in these patients must also be addressed correctly.

Introduction: Breast cancer is the most prevalent tumor in women, ranking first in incidence and mortality in many countries. Although the causes of breast cancer are complex and multifactorial, nutritional factors and those related to nutritional status play an important role in the development of the disease. In this way, factors that increase breast cancer risk have been identified, such as weight gain, the amount of adipose tissue, waist circumference, alcohol consumption or the consumption of red meat and processed meat, while other factors have been identified that reduce the risk, such as eating fruits and vegetables. Nutritional factors or factors that depend on the state of nutrition are modifiable and preventable, so they must be considered when designing effective prevention programs.

Introduction: Anorexia nervosa (AN) is a psychiatric disease with a high prevalence and comorbidities, characterized by a low response rate to treatment. It is considered as a multifactorial disease. In recent years, the focus has been placed on the presence of intestinal dysbiosis and its possible involvement as a causal factor as well as an alternative treatment. The objective of this work has been to review the current state of knowledge of alterations in the intestinal microbiota identified in patients with AN and the possibility of using probiotics as a therapeutic alternative. Significant changes in the diversity of species associated with weight loss have been described that could favor the perpetuation of the disorder, and that would explain many of the nutritional, gastrointestinal, psychological, and cognitive alterations present in these patients. The use of probiotics, still little studied in patients with AN, sheds some light on this matter to improve the treatment response, always hand in hand with conventional treatments.

Introduction: Intermittent fasting is a dietary pattern characterized by alternating periods of total or partial fasting and ad libitum food consumption. During prolonged fasting, the body uses the ketone bodies formed from lipolysis of body fat, which also leads to some metabolic modifications with positive effects on health. In this sense, nocturnal intermittent fasting could contribute to properly synchronize the circadian system making the physiological, hormonal, energetic and metabolic processes work correctly and keeping to the individual in homeostasis. Thus, according to the results of different studies, intermittent fasting, in the short-medium term, seems to improve body composition, as well as the values of several cardiometabolic parameters such as insulin and HOMA-IR index, among others. These effects have been observed in both pre- and postmenopausal women (no differences have been found between both states) and are similar to those found in interventions with caloric restriction diets.

Introduction: Insulin resistance is described as a defect in the binding of insulin to its receptor and is associated with several diseases, including obesity and type 2 diabetes. Insulin resistance has been linked to vitamin and mineral deficiencies, especially those involved in oxidative stress. The Mediterranean diet, a diet based on the Healthy Eating Index or the Dietary Approaches to Stop Hypertension (DASH) diet are dietary patterns that have been associated with a lower risk of developing insulin resistance in children. Therefore, a diet rich in antioxidant vitamins and minerals, fiber, calcium, and polyunsaturated fatty acids and low in free sugars, sodium and saturated fatty acids may decrease the risk of insulin resistance in this age group. In addition, other nutritional factors, such as avoiding fast food, eating dinner with the family, not eating while watching TV or eating a sufficient and healthy breakfast on a regular basis seem to be associated with a lower risk of insulin resistance. Therefore, it is important to establish balanced daily eating habits to prevent and treat insulin resistance in schoolchildren and adolescents.

Introduction: Introduction: eating disorders (EDs) entail a therapeutic challenge. Objective: to describe ED care from the perspective of Nutrition Units (NU) in relation to human and care resources, the activities carried out, and satisfaction with care in Spain; to collect demands from professionals to improve assistance. Methods: a cross-sectional, observational study based on a questionnaire sent online to members of the Spanish Society of Clinical Nutrition and Metabolism (SENPE) and to the Nutrition Area of the Spanish Society of Endocrinology and Nutrition (SEEN). The data were analyzed according to number of beds of the hospitals surveyed (< 500/≥ 500). Results: 23 responses from 8 autonomous communities. In 87 % of NUs care was given to eating disorders; 65.2 % had a specific process; 91.3 % collaborated with Psychiatry; 34.8 % had their own hospitalization area; 56.5 % had a day hospital, but 21.7 % participated in it; 39.1 % had a monographic consultation office; nutritional education was carried out in 87 %, especially by nursing; individualized diets and oral supplements were frequently prescribed in 39.1 % and 56.5 %, respectively; only the largest hospitals participated in research on EDs (62.5 %), and 21.7 % collaborated with patient associations. Hospitals with ≥ 500 beds had more resources and were more satisfied. Professionals demanded resources and processes agreed with Psychiatry. Conclusions: resources and care practices are uneven in the NUs surveyed, as well as multidisciplinary collaboration. The collected evidence allows us to design improvement strategies in this area.

Background: Breakfast has traditionally been considered one of the most important meals of the day; however, there is little evidence for the influence of breakfast quality and insulin resistance (IR). This study aimed to assess the quality of breakfast in a group of schoolchildren, and its association with IR. Methods: A cross-sectional study with 852 children (8−13 years) was carried out. Fasting plasma glucose, insulin and anthropometric parameters were measured. A three-day dietary record was used to assess their diet and to calculate the Breakfast Quality Index (BQI). The sample was divided into tertiles according to the BQI (tertile 3: better breakfast quality). The homeostatic model was used to assess insulin resistance (HOMA-IR), and IR was defined as HOMA-IR > 3.16. Results: The prevalence of IR was 5.2%. The mean BQI score was 4.50 ± 1.25, and boys had lower scores than girls. Children in the BQI tertile 3 had a better global diet quality. In boys, being in the BQI tertile 3 was associated with a lower risk of IR (OR [95% CI]: 0.10 [0.01−0.77], p < 0.05). Conclusions: A higher-quality breakfast was associated with better overall diet quality and a lower risk of IR, especially in boys.

Excess weight (EW) in children has become a severe public health problem. The present study aimed to describe the main lifestyle characteristics and their possible association with nutritional status in a group of schoolchildren enrolled in the GENYAL study, where 221 children in the first or second grade of primary education (6-9 years old) were included. Anthropometric (BMI and bioimpedance), dietary intake (twice-repeated 24 h food record), and physical activity (twice-repeated 24 h physical activity questionnaire) data were collected. Logistic and linear regressions, with p -values adjusted for multiple tests by Bonferroni's method and with sex and age as covariates, were applied. The prevalence of EW was 19%, 25.4%, and 32.2%, according to Orbegozo Foundation, IOFT, and WHO criteria, respectively. The results showed a significant association between schoolchildren's nutritional status and energy balance, defined as the ratio of estimated energy intake to estimated energy expenditure (%), (β = -1.49 (-1.9-1.07), p < 0.01) and KIDMED Mediterranean Diet Quality Index score (β = -0.19 (95% IC -0.38-0), p = 0.04), and between the availability of TV or other technological devices in their room and the child's BMI (β = 1.15 (95% IC 0.20-2.10), p = 0.017) and their fat mass (β = 3.28 (95% IC 0.69-5.87), p = 0.013). The number of dairy servings/day had a protective effect against EW (OR = 0.48 (0.29-0.75), p adjusted = 0.05)). Studying lifestyle factors associated with obesity is essential for developing tools and strategies for obesity prevention in children.

Background: Overweight and obesity are defined by an anomalous or excessive fat accumulation that may compromise health. To find single-nucleotide polymorphisms (SNPs) influencing metabolic phenotypes associated with the obesity state, we analyze multiple anthropometric and clinical parameters in a cohort of 790 healthy volunteers and study potential associations with 48 manually curated SNPs, in metabolic genes functionally associated with the mechanistic target of rapamycin (mTOR) pathway., Results: We identify and validate rs2291007 within a conserved region in the 3'UTR of folliculin-interacting protein FNIP2 that correlates with multiple leanness parameters. The T-to-C variant represents the major allele in Europeans and disrupts an ancestral target sequence of the miRNA miR-181b-5p, thus resulting in increased FNIP2 mRNA levels in cancer cell lines and in peripheral blood from carriers of the C allele. Because the miRNA binding site is conserved across vertebrates, we engineered the T-to-C substitution in the endogenous Fnip2 allele in mice. Primary cells derived from Fnip2 C/C mice show increased mRNA stability, and more importantly, Fnip2 C/C mice replicate the decreased adiposity and increased leanness observed in human volunteers. Finally, expression levels of FNIP2 in both human samples and mice negatively associate with leanness parameters, and moreover, are the most important contributor in a multifactorial model of body mass index prediction., Conclusions: We propose that rs2291007 influences human leanness through an evolutionarily conserved modulation of FNIP2 mRNA levels., (© 2022.

Background: Diet quality patterns are associated with a lower incidence of insulin resistance (IR) in adults. The aim of this study was to investigate the association between two diet quality indices and IR in schoolchildren and to identify the best diet quality index associated with a lower risk of IR. Methods: A total of 854 schoolchildren (8−13 years) were included in a cross-sectional study, who completed a three-day dietary record to assess their diet. Fasting plasma glucose and insulin were also measured, and anthropometric data were collected. Healthy Eating Index-2015 (HEI-2015), Dietary Approaches to Stop Hypertension (DASH), and adjusted DASH (aDASH) were calculated as diet quality indices. The homeostasis model assessment of insulin resistance (HOMA-IR) was used, and IR was defined as HOMA-IR > 3.16. Results: The prevalence of IR was 5.5%, and it was higher in girls. The mean HEI-2015 and DASH scores were 59.3 and 23.4, respectively, and boys scored lower in both indices. In girls, having a HEI-2015 score above the 33rd percentile was associated with a lower risk of IR (odds ratio [95% CI]: 0.43 [0.19−0.96], p = 0.020). Conclusion: Greater adherence to a healthy dietary pattern, as assessed by a higher HEI-2015 score, was associated with a lower risk of IR in schoolchildren, especially in girls., Competing Interests: Authors declare no conflict of interest.

Fasting exerts beneficial effects in mice and humans, including protection from chemotherapy toxicity. To explore the involved mechanisms, we collect blood from humans and mice before and after 36 or 24 hours of fasting, respectively, and measure lipid composition of erythrocyte membranes, circulating micro RNAs (miRNAs), and RNA expression at peripheral blood mononuclear cells (PBMCs). Fasting coordinately affects the proportion of polyunsaturated versus saturated and monounsaturated fatty acids at the erythrocyte membrane; and reduces the expression of insulin signaling-related genes in PBMCs. When fasted for 24 hours before and 24 hours after administration of oxaliplatin or doxorubicin, mice show a strong protection from toxicity in several tissues. Erythrocyte membrane lipids and PBMC gene expression define two separate groups of individuals that accurately predict a differential protection from chemotherapy toxicity, with important clinical implications. Our results reveal a mechanism of fasting associated with lipid homeostasis, and provide biomarkers of fasting to predict fasting-mediated protection from chemotherapy toxicity., (© 2022.

Dysbiosis of the microbiome has been related to Celiac disease (CeD) progress, an autoimmune disease characterized by gluten intolerance developed in genetically susceptible individuals under certain environmental factors. The microbiome contributes to CeD pathophysiology, modulating the immune response by the action of short-chain fatty acids (SCFA), affecting gut barrier integrity allowing the entrance of gluten-derived proteins, and degrading immunogenic peptides of gluten through endoprolyl peptidase enzymes. Despite the evidence suggesting the implication of gut microbiome over CeD pathogenesis, there is no consensus about the specific microbial changes observed in this pathology. Here, we compiled the largest dataset of 16S prokaryotic ribosomal RNA gene high-throughput sequencing for consensus profiling. We present for the first time an integrative analysis of metataxonomic data from patients with CeD, including samples from different body sites (saliva, pharynx, duodenum, and stool). We found the presence of coordinated changes through the gastrointestinal tract (GIT) characterized by an increase in Actinobacteria species in the upper GIT (pharynx and duodenum) and an increase in Proteobacteria in the lower GIT (duodenum and stool), as well as site-specific changes evidencing a dysbiosis in patients with CeD' microbiota. Moreover, we described the effect of adherence to a gluten-free diet (GFD) evidenced by an increase in beneficial bacteria and a decrease in some Betaproteobacteriales but not fully restoring CeD-related dysbiosis. Finally, we built a Random Forest model to classify patients based on the lower GIT composition achieving good performance., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Arcila-Galvis, Loria-Kohen, Ramírez de Molina, Carrillo de Santa Pau and Marcos-Zambrano.)

Introduction: European Union represents a tenth of the world population, however, it has a quarter of the cancer cases in the world. Without strong action, it is estimated that by 2035 cancer cases will increase by almost 25 %, making this disease the main cause of death. Therefore, the aim of this study is to know the diet and lifestyle guidelines associated to cancer prevention. A literature review has been carried out on the diet and lifestyle guidelines related to a reduction in cancer risk. Strategies to reduce cancer risk include maintaining a healthy weight, being physically active, consuming a diet rich in whole grains, fruits, non-starchy vegetables, and legumes, limit processed and fast food, limit consumption of red meat and eat little, if any, processed meats, drink mostly water and limit the consumption of sugar sweetened drinks, finally reduce, or do not consume alcohol. Prevention is an effective tool to reduce cancer risk. Adequate diet and healthy lifestyle habits can reduce cancer risk as well as other non-communicable diseases and can even have environmental benefits.

Introduction: The gut microbiota has emerged as a key factor on one hand as a mediator of the effects of diet on health and, on the other hand, as a source of intervariability of response to a diet. Moreover, there is a strong bidirectional interaction between our health and the microbiota that inhabit us, with each determining the presence of the other. In this review are named some of the metabolic functions in which the microbiota participates and which have an impact on our health, with particular emphasis on its ability to ferment fiber and produce short-chain fatty acids (SCFA) that provide numerous benefits to our health, but which have also been linked to obesity. Finally, some examples of dietary intervention in which the microbiota has been shown to play a key role in the results obtained are mentioned.

Introduction: Vitamin D is a key nutrient for health. Recent research has shown that it is not only necessary for the maintenance of bone health, but also for the prevention of cardiovascular diseases, insulin resistance, respiratory diseases, infections, and cancer, among others. Solar synthesis of vitamin D is usually insufficient, so it is necessary to provide enough vitamin D through the diet in order to maintain an adequate nutritional status. Studies carried out in Spain and other countries have shown that serum levels of the vitamin were usually insufficient and that average dietary intakes were well below those marked as recommended, while the main food sources of vitamin D were fatty fish, breakfast cereals, eggs, and dairy. Food sources of vitamin D are scarce, and it is naturally located in the fatty part of foods of animal origin, and in the liver and viscera. Fortifying foods that are not natural food sources of vitamin D but are regularly consumed by a significant percentage of the population, is a strategy that could help to increase vitamin D intake. In this regard, dairy products and breakfast cereals are two of the most widely used food matrices for vitamin D fortification, and their incorporation into the usual diet has proven to be an effective strategy to improve the nutritional situation of the population in vitamin D.

Introduction: The consumption of high nutritional quality foods is a key for proper growth and development during childhood. This work aimed to review and analyse the current recommended egg intake in children by different national organisations. Likewise, it intended to standardise a procedure to propose new recommendations for this food. A search of available national online guidelines or recommendations was performed. The Healthy Eating Guide of the Spanish Society of Community Nutrition (SENC), 2018 and the energy requirements of the European Food Safety Authority (2017) for children and adolescents were contemplated, considering a contribution of 15 % of energy as proteins to propose the new recommended egg intake. Two scenarios according to the level of physical activity and three age groups were considered. Based on the current data and evidence, we believe that egg intake recommendations should be reassessed, proposing broader recommendations, especially for children over 13 years old with average energy requirements as well as children over seven years old who perform high physical activity or are in a brief period of growth. It will contribute to breaking down old myths associated with egg consumption and promote the development of coordinated and updated recommendations.
