Objective: Examine the association between energy intake and television (TV) viewing in Americans.
Design: Nationally representative, cross-sectional study of 2003-2006 National Health and Nutrition Examination Survey.
Setting: Total energy intake was determined by two 24 h recalls. TV viewing was reported as low (≤1 h/d), middle (2-3 h/d), and high (≥4 h/d). Multivariate linear regression models were used to analyse TV viewing and energy intake, adjusted for BMI (percentile for children 2-18 years), age, ethnicity and physical activity.
Subjects: Pre-school children (2-5 years; n 1369), school-age children (6-11 years; n 1759), adolescents (12-18 years; n 3233) and adults (≥19 years; n 7850) in the USA.
Results: There was a significant association between TV viewing and energy intake for adolescent girls (high v. low: β = 195·2, P = 0·03) and men (high v. low: β = -113·0, P = 0·02; middle v. low: β = -131·1, P = 0·0002). Mean adjusted energy intake for adolescent girls was 7801·0, 8088·5 and 8618·2 kJ/d for low, middle and high TV viewing, respectively. Mean adjusted energy intake for men was 9845·9, 9297·2 and 9372·8 kJ/d for low, middle and high TV viewing.
Conclusions: TV viewing was associated with energy intake in US children and adults only in 12-18-year-old girls and men. For girls, the high TV viewing category consumed more energy daily (816·3 kJ (195 kcal)) than the low category. In men, the middle and high TV viewing categories consumed less energy daily (548·4 kJ (131 kcal) and 473·0 kJ (113 kcal), respectively) than the low category. Our findings support some, but not all previous research. Future research is needed to explore this complicated relationship with rigorous measures of energy intake and TV viewing.

Does physical activity level and total energy expenditure relate to food intake, appetite, and body composition in healthy older adults? A cross-sectional study.

Purpose: With ageing, older adults (≥ 65 years) may experience decreased appetite, contributing to declines in body weight and muscle mass, potentially affecting physical capabilities. Physical activity (PA) has been suggested as a potential strategy to enhance appetite in older adults, but evidence supporting this is insufficient. This study aimed to investigate the relationship between PA levels, total energy expenditure (TEE), body composition, energy intake (EI) and appetite in older adults.

Plant-based dietary patterns have been demonstrated to reduce the risk of non-communicable disease (NCD), including cardiovascular disease (CVD), type 2 diabetes, cancer, and all-cause mortality. Phenolic compounds (PC), abundant in plant-based foods, have been considered as instrumental in this attenuation of NCD risk. We evaluated the association between dietary intake of PC and the risk of all-cause mortality in a relatively young Mediterranean cohort of 18,173 Spanish participants in the "Seguimiento Universidad de Navarra" (SUN) project, after a median follow-up of 12.

Besides their nutritional role, proteins are recognized for their ability to regulate both short- and long-term energy homeostasis. However, studies investigating the effects of proteins based on their quality and origin remain limited and often lack comparability. Nonetheless, existing research consistently underscores the influence of proteins on food intake regulation.
