COLUMBUS, Ohio – New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene.

This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient.

But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the body: They actually block some actions of vitamin A, which is critical to human vision, bone and skin health, metabolism and immune function. (more…)

A surprising new University of Colorado Boulder study shows that huge amounts of fatty acids circulating in the bloodstreams of feeding pythons promote healthy heart growth, results that may have implications for treating human heart disease.

CU-Boulder Professor Leslie Leinwand and her research team found the amount of triglycerides — the main constituent of natural fats and oils — in the blood of Burmese pythons one day after eating increased by more than fiftyfold. Despite the massive amount of fatty acids in the python bloodstream there was no evidence of fat deposition in the heart, and the researchers also saw an increase in the activity of a key enzyme known to protect the heart from damage.

Tamas Horvath is the first to tell you that he doesn’t study obesity. But his research on the effects of metabolism on higher brain functions could provide deeper understanding of the brain’s link to appetite, weight and to metabolic disorders such as diabetes and obesity.

His lab was the first to provide evidence that the brain uses fat as fuel. Horvath has also studied how endocrine signals in the brain regulate neurodegenerative diseases such as Parkinson’s and Alzheimer’s.

Horvath followed his father and grandfather into veterinary medicine in his native Hungary, but his training sparked a passion for basic research. His achievements have earned him a long title that speaks to his varied research interests. He became chair of the Department of Comparative Medicine at Yale School of Medicine in 2005, and he is also a professor in the Departments of Obstetrics, Gynecology & Reproductive Sciences and Neurobiology. Horvath also heads the Program on Integrative Cell Signaling and the Neurobiology of Metabolism. (more…)
