New research from the University of Pennsylvania suggests that physiology, particularly the vagus nerve, plays a role in gender differences in food choices. Studies found that women exhibited diminished vagally-mediated hormonal and gastric responses to food compared to men, which could explain why women tend to prefer healthier foods.
The study, conducted by Virginia Tech researchers, analyzed data from the National Health and Nutrition Examination Survey III. It found that regular soft drink consumption was not associated with dental cavities among adolescents, young adults, or older adults.

The authors suggest reevaluating current low-fat diet recommendations for individuals with excess body weight.
A new study found that puberty causes a general metabolic slowdown in both white and African American adolescents, with African Americans having greater lean mass in limbs but lower lean mass in the trunk. This difference may contribute to a lower resting energy expenditure (REE) in African Americans.
