Researchers from University of Toronto found that environmental cues, such as portion size, palatability, and social norms, dominate eating decisions rather than physical or nutritional needs. This 'zone of biological indifference' makes individuals vulnerable to socially-based influences, leading to overeating.
A study of 12 normal-weight individuals found that their eating behavior did not compensate for overeating, despite gaining weight. Instead, they maintained their usual eating patterns when returning to their normal environment.
Biological differences in taste sensitivity have been linked to various health risks, including colon cancer and cardiovascular disease. Supertasters are more likely to avoid vegetables due to their bitter taste, but this may lead to a higher risk of certain cancers.
A team of UC Irvine researchers found that pythons expend excessive energy in digestion when consuming protein-rich foods. The study revealed that the metabolic rate needed for digestion is based on the content of the food, not its volume.
A Texas A&M University research team is counting Bowhead whales in the Okhotsk Sea to estimate their population size and understand the impact on the ecosystem. By using photo identification and genetic testing, researchers hope to gather information on the whales' feeding behavior and determine if their food supply is dwindling.
Researchers pinpointed the time it takes for the human brain to signal fullness and identified areas involved in eating. The study used functional magnetic resonance imaging (fMRI) to record activity changes in neurons, finding a connection between brain activity and traditional biochemical indicators like glucose and insulin levels.
