- Food Choice, Nutrition, and Public HealthPublication . Santos, Mariana; Assunção, RicardoMaintaining a healthy diet throughout life helps prevent all forms of malnutrition, thereby reducing the risk of non-communicable diseases (NCDs) and related conditions . Dietary habits, lifestyle choices, and social factors significantly influence our health. Recently, we have seen shifts in food consumption patterns driven by various factors. These include the increased availability of processed foods, rapid urbanization, and changing lifestyles. The types, amounts, and frequency of consumed foods and beverages define dietary patterns, which have been evolving in recent decades due to the emergence of new or adapted eating habits. Common examples of dietary patterns include the ‘Western dietary pattern’ and the ‘Mediterranean dietary pattern’. Other significant patterns are the ‘prudent dietary pattern’, which emphasizes a high intake of vegetables, fruits, legumes, whole grains, fish, and seafood, and the ‘vegetarian/plant-based dietary pattern’, which entirely omits meat and animal products. Understanding the individual motives that drive certain food choices is crucial for changing consumption habits, promoting healthier behaviors, and fostering sustainability. This Editorial introduces the Special Issue “Food Choice, Nutrition, and Public Health” and highlights key topics on this subject.
- Nutritional and Bioactive Profiling of Cucumis melo L. By-Products: Towards a Circular Food EconomyPublication . Silva, Mafalda A.; Albuquerque, Tânia G.; Ferreira, Diana M.; Alves, Rita C.; Oliveira, Maria Beatriz P.P.; Costa, Helena S.Food waste, due to the high quantities produced, becomes a significant environmental, economic, and social challenge worldwide. Simultaneously, the rising prevalence of chronic diseases has intensified the demand for healthier food options. A promising approach to address these issues involves the valorisation of food by-products for the development of innovative and healthier food products. Cucumis melo L., commonly consumed as a fruit, generates peels and seeds that are typically discarded. In the present study, the nutritional composition and antioxidant potential of pulp, peel, and seeds of C. melo L. (yellow and green melon) were comprehensively evaluated. The seeds were identified as a rich source of dietary fibre (39.0 and 39.7 g/100 g dw; p > 0.05) and protein (21.0 and 21.3 g/100 g dw; p > 0.05), exhibiting an appealing fatty acid profile. The peel contains high levels of dietary fibre (39.7 and 47.1 g/100 g dw; p > 0.05) and total phenolic compounds (1976 and 2212 mg GAE/100 g dw; p > 0.05), suggesting significant bioactive potential. The peels showed a high antioxidant capacity for both methods used, DPPH• (120 and 144 mg TE/100 g dw; p > 0.05) and FRAP (6146 and 7408 mg TE/100 g dw; p > 0.05) assays. Potassium emerged as the predominant mineral in the seeds (799 and 805 mg/100 dw; p > 0.05), while glutamic acid was the most abundant amino acid (4161 and 4327 mg/100 g dw; p > 0.05). These findings emphasise the antioxidant and nutritional properties of C. melo L. by-products, highlighting their potential for inclusion in novel food formulations. This study not only advances the understanding of C. melo L. properties but also supports the reduction of food waste and promotes sustainability within the food supply chain.
- Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adultsPublication . NCD Risk Factor Collaboration group; Rito, AnaBackground: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods: We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5-19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For school-aged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings: From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation: The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesity.
