Objective: This study identified perceptions of family meal benefits and family meal preplanning patterns among African Americans (AAs) living in health disparity zip codes in the Deep South. Design: Surveys that included demographic information, perceptions about family meal benefits, and preplanning behaviors Results: Study participants with limited meal preplanning practices were less likely...

Rats and mice were studied for changes in meal-taking structure in a closed operant food economy, in which the consummatory or unit prices for food were increased. In experiment 1, as food price increased, male rats modestly decreased the number of meals per day and increased mean meal size. Female rats were similar to males but had smaller meal size and, at low costs, took more meals per day. ...

Because food intake is a function of meal number and meal size and because gender-related hormones are involved in feeding regulation, we explored effects of orchiectomy and testosterone replacement on the relationship between meal number and size and changes in resulting feeding patterns in adult male rats, randomized into orchiectomy and sham-operation groups. A rat eater meter measured feedi...

Rats typically eat in short discrete meal periods separated by long intermeal intervals. The present study measured meal patterns and total intake of food and water when the rate of access to food pellets within the meal was reduced by delaying the time between pellet deliveries. In contrast to studies that reduce the caloric density of food, simple interpellet delay produced a marked reduction...

Far more attention has been paid to the microbes in our feces than the microbes in our food. Research efforts dedicated to the microbes that we eat have historically been focused on a fairly narrow range of species, namely those which cause disease and those which are thought to confer some "probiotic" health benefit. Little is known about the effects of ingested microbial communities that are ...

The macronutrient composition of the diet has been shown to affect food intake, with proteins having distinct effects. The present study investigated the effect of diet supplementation with individual amino acids (tryptophan, lysine, arginine, proline and threonine) on meal pattern among male rats. Meal pattern and body weight were monitored for two weeks. Proline and threonine had minimal effe...

BACKGROUND Colorectal resections alter colonic motility, including disruption of control by neural or bioelectrical cell networks. The long-term impact of surgical resections and anastomoses on colonic motor patterns has, however, never been assessed accurately. Fibreoptic high-resolution colonic manometry was employed to define motility in patients who had undergone distal colorectal resection...
