Diet is one of the elements that contribute to health and quality of life. There are significant discrepancies between the diets of people living in different regions, with different beliefs, or with different approaches to sustainability and ecology. There is a lack of research on dietary intake among organic and conventional fruit growers. The aim of our study was to examine the diets of orchardists and their immediate life partners in terms of meeting energy requirements, nutrient intake and fulfillment of dietary recommendations in this group. Fifty-three participants (28 in the organic group and 25 in the conventional group) took part in the study. Dietary data were obtained using the 3-day dietary record. Body mass and height were measured and BMI was calculated. Physical activity was estimated using a questionnaire method. The study group was aged 44 ± 8 years, with a body weight of 84 ± 16 kg and a height of 172 ± 9 cm. The mean BMI was 28 ± 4 kg/m2. Mean energy intake with diet was 2170 ± 606 kcal/day with needs of 3002 (1991–5144) kcal/day. A significant proportion of the study group did not fulfill their calcium and vitamin D requirements. In addition, a significant proportion of the conventional fruit growers did not cover their needs for potassium, magnesium and vitamins: E, C, and folate. Both groups had too high an intake of cholesterol and saturated fatty acids, and too low an intake of polyunsaturated fatty acids. In conclusion, the orchardists' diets mostly provided adequate amounts of nutrients, with inadequate intakes of calcium, vitamin D, cholesterol, and fatty acids. The diets of organic fruit growers were significantly richer in selected nutrients.

Background. The most important component of a well-balanced diet is the proper energetic value. However, adequate estimation of the body’s energy needs is difficult for professional athletes, including soccer players. There is little research showing energy expenditure during training and lack of studies on the energy expenditure of professional female soccer players during a match. Objective. The aim of our study was to estimate energy expenditure during training and official league match in female soccer players and comparing it. Material and methods. Seven Polish professionally practicing soccer females (23.4±6,6 years old; 63.5±7.8 kg; 168.5±5.8 cm; 46±4.4 kg fat-free mass) participated in the study. The participants had their height and body mass measured. Energy expenditure during activities was measured by means of a SenseWear Pro3 Armband device. Body composition was assessed with Akern BIA 101 Anniversary Sport Edition device. Results. Statistically higher energy expenditure was achieved in the study group during the match hour (452±55 kcal/hour) compared to the training hour (353±28 kcal/ hour) as well as in the case of energy expenditure per hour of activity per kg of fat-free mass (match: 9.94±1.75 kcal/kg fat-free mass/hour; training: 7.71±0.8 kcal/kg fat-free mass/hour). During one hour of training, more time was spent on sedentary, light, and moderate activities, but the difference was statistically significant only for light activities. More time during the match hour than during the training hour was spent on vigorous and very vigorous activities. Conclusions. In conclusion, the energy expenditure of the players during the match was greater than in the case of the planned intensive training, which was caused by the timeshare of more intense physical activities and going a longer distance during match.

Front-of-pack labelling (FOPL) systems, such as the Nutri-Score, play a crucial role in promoting healthy diets and raising consumer awareness. Our study aimed to gather the opinions of Polish experts on the Nutri-Score and its relation to an ideal information system. We conducted a Poland-wide expert opinion study using a cross-sectional design survey with 75 participants, who had an average of 18 ± 13 years of experience and were mainly employed at medical and agricultural universities. The data were collected with the CAWI method. The results showed that the most important features of an FOPL system were clarity, simplicity, consistency with healthy eating recommendations, and the ability to objectively compare products within the same group. While more than half of the respondents believed that the Nutri-Score provides an overall assessment of a product’s nutritional value and facilitates quick purchasing decisions, it falls short in helping consumers compose a balanced diet and cannot be applied to all product groups. The experts also expressed concerns about the system’s ability to account for a product’s degree of processing, full nutritional value and carbon footprint. In conclusion, Poland’s current labelling system needs expansion, but the Nutri-Score requires significant and detailed changes and validation against national guidelines and expert expectations before implementation.

Background. The most important element of a well-balanced diet is a proper energetic value. Energy deficiencies are often observed in athletes, especially women. Energy deficiencies can lead to low energy availability which can cause serious health problems and affect exercise capacities. There is, therefore, a risk of health complications and reduced physical performance among female soccer players. Objective. The aim of this study was to check the frequency of low energy availability appearance in a group of women training soccer, which could results in negative health effects due to Relative Energy Deficiency in Sport (RED-S). Material and methods. Thirty-one professional female soccer players practicing on different league levels (Extra-league, I league, II league) participated in the study. The participants had their height and body mass measured. To assess the Energy Intake the method of 3-day dietary food recording was used. Total Energy Expenditure (TEE) and Exercise Energy Expenditure (EEE) was measured by means of an Armband SenseWear Pro3 device. The content of fat free mass was assessed with Akern BIA 101 Anniversary Sport Edition device. Results. The body mass median of participants was 58 kg. The average height was 166±5 cm, and the average BMI was 21.4±2 kg/m2. TEE was 2703±392 kcal/day, while EEE was 515 kcal (203-597 kcal). Energy intake was 1548±452 kcal/day. Energy availability was 25±11 kcal/kg fat free mass/day. Twenty of the study participants had low energy availability. The percentage of EEE in TEE was 17.93±3.14%. Conclusions. Low energy availability was demonstrated in the vast majority of studied group, which may lead to negative health consequences or reduction of exercise capacity.

Soccer is one of the most popular sports in the world. As its number of players is increasing, the number of female players is also on the rise. However, there are limited data about how the diets of female soccer players should be designed. Thus, the aim of our work is to deliver concise nutritional recommendations for women practicing this sport. Based on a literature review, we emphasize that individual adjustment of the energy value of the diet is the key factor for the physical performance of female soccer players. Appropriate macronutrient intake makes it possible to achieve the proper energy value of the diet (5−10 g/kg body mass/day carbohydrates; 1.2−1.7 g/kg body mass/day proteins;
