Abstract

BACKGROUND/OBJECTIVES: As taste preferences may be associated with obesity, the present study investigated whether obese subjects presented heightened liking for the sensations of sweet, salt and fat. SUBJECTS/METHODS: Liking scores were determined by a questionnaire including 83 items on liking for sweet or fatty foods, and the preferred extent of seasoning with salt, sweet or fat. Data from 46 909 adults included in the French web-based observational cohort of the Nutrinet-Sante study were collected and weighted according to the national population census. Relationships between liking scores and body mass index (BMI) as categorical or linear explanatory variable were assessed separately by gender using covariance and linear regression analyses, adjusted for age, education level, living area, smoking and alcohol. RESULTS: Overall liking scores for salt and fat were linearly positively linked to BMI in men and women (P [less than or equal to] 0.001) and were higher in obese than in normal-weight individuals. The score difference between BMI categories was greater in women for fat liking only. For sweet liking, results differed between gender and compounding factors. Liking for added sugar and sweet foods was positively linked to BMI in women unlike in men; liking for natural sweetness was negatively linked to BMI in both genders. CONCLUSIONS: This study demonstrates that the relationship between liking and BMI differs according to the gender in its magnitude for fat and in its nature for sweet, unlike that for salt. Liking for sweet and fat may be linked to overconsumption of the corresponding foods, especially in women. This warrants further investigation.

Abstract

Background/Objectives: Lower-income subgroups consume fewer servings of fruit and vegetables (FVs) compared with their more advantaged counterparts. To overcome financial barriers, FV voucher delivery has been proposed. Subjects/Methods: In a 12-month trial, 302 low-income adults 18-60 years old (defined by evaluation of deprivation and inequalities in health examination centers, a specific deprivation score) were randomized into two groups: dietary advice alone ('advice'), or dietary advice plus FV vouchers ('FV vouchers') (10-40 euros/month) exchangeable for fresh fruits and vegetables. Self-reported data were collected on FV consumption and socioeconomic status at baseline, 3, 9 and 12 months. Anthropometric and blood pressure measurements were conducted at these periods, as well as blood samples obtained for determination of vitamins. Descriptive analyses, multiple linear regression and logistic regression were performed to evaluate the impact of FV. Results: Between baseline and 3-month follow-up, mean FV consumption increased significantly in both the 'advice' (0.62 [+ or-] 1.29 times/day, P = 0.0004) and 'FV vouchers' groups (0.74 [+ or-] 1.90, P = 0.002), with no difference between groups. Subjects in the FV vouchers group had significantly decreased risk of low FV consumption ( Conclusion: In the low-income population, FV voucher delivery decreased the proportion of low FV consumers at 3 months. Longer-term studies are needed to assess their impact on nutritional status.

Abstract

Background/Objectives: Few studies in Europe have examined the relationship of sociodemographic and economic factors with diet in deprived populations. We analysed the association between socioeconomic characteristics and consumption of different food groups in food aid users. Subjects/Methods: A cross-sectional study was conducted among food aid users in four urban French zones (n = 1664). Associations of sociodemographic and economic factors and food aid use with frequency of consumption of the main food groups were tested using multivariate logistic regression models accounting for sampling weights. Results: Both migrant status and consumption of fewer than three daily meals were associated with risk of low frequency of starchy food consumption (< 3 times per day). Migrant status was also associated with low frequency of consumption of fruits and vegetables (< 3.5 times per day) and dairy products ( Conclusions: Economic level and other social characteristics were associated with an unhealthy diet within this deprived French population.

Abstract

Tunisia is a typical country of the Mediterranean region where high prevalence of overweight, obesity and noncommunicable diseases co-exist with some micronutrient deficiencies, and diet-related environmental issues must be addressed. Individual food choices may influence both health and environment. The aim of this study was to identify diets that are nutritionally adequate, culturally acceptable, and with low environmental impact for Tunisian adults. Individual dietary data from a national Tunisian survey on food consumption (n = 7209, 35-70 years) and the national food composition table were used to estimate the food and nutritional content of the mean observed (OBS) diet. The diet environmental impact was assessed through seven metrics: water deprivation, land-use, land-use potential impacts on biodiversity loss, erosion resistance, mechanical filtration, groundwater replenishment, and biotic production. Quadratic optimization models were implemented to obtain diets that met the nutritional recommendations, and concomitantly respected increasingly stringent environmental constraints and minimized the departure from the OBS diet. Without environmental constraints, the nutritional recommendations were met by increasing the amount of dairy, starch and vegetables, and decreasing foods high in fat/salt/sugar (HFSS) and added fat. Compared with the OBS diet, the environmental impact of this diet increased: + 32% for water deprivation and + 46-48% for land use and its impacts. When a moderate environmental impact reduction (= 40%) required substantial changes that might compromise the optimized diet acceptability. Targeting a nutritionally adequate diet without considering its environmental impact might increase water deprivation, land use and its impacts on biodiversity and soil quality. In Tunisia, moving towards healthy diets with lower environmental impact relied more on redistributing the sources of animal-based products rather than on reducing their total contribution, together with a decrease of HFSS and added fats, and an increase of vegetables. Actions to favor the adoption of such dietary changes by consumers should be explored to promote more sustainable diets in the Mediterranean region.
