Television watching has been positively associated with overeating and obesity. How popular food-related television shows affects eating behavior has not been examined. An experimental study was conducted to examine how exposure to a food-related television program affects amount and type of food consumed in adults (N=80). Participants were randomized to watch a cooking or nature television program and were then presented with 800 total calories of chocolate covered candies, cheese curls, and carrots. Food was weighed before and after the ad libitum eating session to determine amount consumed. After controlling for dietary restraint, hunger and food preference, significantly more chocolate covered candies were consumed among individuals who watched the cooking program compared to the nature program. No significant differences between conditions were found for overall caloric intake or for cheese curl or carrot consumption. Findings suggest that watching food-related television programs may affect eating behavior and has implications for obesity prevention and intervention efforts.

Modification of the School Cafeteria Environment Can Impact Childhood Nutrition: Results from the Wise Mind and LA Health Studies.

Recent changes in nutrition standards for the National School Lunch and School Breakfast Programs assume that modification of the nutritional serving practices of school cafeterias will result in improved childhood nutrition in the school environment. The primary aim of this paper is to summarize the findings from two recent cluster randomized controlled trials (Wise Mind and LA Health) that tested the hypothesis that modification of school cafeteria environments, including changes in nutrition standards, would yield beneficial changes in childhood nutrition and healthy eating in the school lunch environment. A secondary aim was to investigate the association of participant characteristics and changes in nutrition and healthy eating. A third aim was to investigate the relationships between the food intake of children and: 1) foods selected by the children and 2) food that was uneaten during the lunch meal (plate waste). The studies used similar approaches for modifying the school cafeteria environment and both studies used the digital photography method to measure changes in food intake, food selection, and plate waste. Both studies reported significant improvements in childhood nutrition, and the LA Health study reported improved healthy eating, following introduction of the cafeteria modification program in comparison to baseline and/or control arms. These studies confirm the hypothesis that interventions that modify the school cafeteria environment can beneficially impact childhood nutrition.

RATIONALE: Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) have alterations of measures of serotonin (5-HT) and dopamine (DA) function, which persist after long-term recovery and are associated with elevated harm avoidance (HA), a measure of anxiety and behavioral inhibition. OBJECTIVE: Based on theories that 5-HT is an aversive motivational system that may oppose a DA-related appetitive system, we explored interactions of positron emission tomography (PET) radioligand measures that reflect portions of these systems. METHODS: Twenty-seven individuals recovered (REC) from eating disorders (EDs) (7 AN-BN, 11 AN, 9 BN) and nine control women (CW) were analyzed for correlations between [(11)C]McN5652 and [(11)C]raclopride binding. RESULTS: There was a positive correlation between [(11)C]McN5652 binding potential (BP(non displaceable(ND))) and [(11)C]raclopride BP(ND) for the dorsal caudate (r(27)=0.62; p<0.001), antero-ventral striatum (AVS) (r(27)=0.55, p=0.003), middle caudate (r(27)=0.68; p<0.001), ventral (r(27)=0.64; p<0.001) and dorsal putamen (r(27)=0.42; p=0.03). No significant correlations were found in CW. [(11)C]raclopride BP(ND), but not [(11)C]McN5652 BP(ND), was significantly related to HA in REC EDs. A linear regression analysis showed that the interaction between [(11)C]McN5652 BP(ND) and [(11)C]raclopride BP(ND) in the dorsal putamen significantly (b=140.04; t (22)=2.21; p=0.04) predicted HA. CONCLUSIONS: This is the first study using PET and the radioligands [(11)C]McN5652 and [(11)C]raclopride to show a direct relationship between 5-HT transporter and striatal DA D2/D3 receptor binding in humans, supporting the possibility that 5-HT and DA interactions contribute to HA behaviors in EDs.

Anaphylaxis from ingestion of mites: Pancake anaphylaxis.

Oral mite anaphylaxis is a new syndrome characterized by severe allergic symptoms occurring immediately after eating foods made with mite-contaminated wheat flour. This syndrome, which is more prevalent in tropical environments, is triggered more often by pancakes, and for that reason, it has been designated “the pancake syndrome.” Because cooked foods are able to induce the symptoms, it has been suggested that thermoresistant allergens are involved in its pathogenesis. A variety of this syndrome can occur during physical exercise (dust mite ingestion-associated exercise-induced anaphylaxis).
