It is widely known that episodes of high stress, even short ones, temporarily impair artery function. To make things worse, people often eat high-fat foods in times of stress, which puts more stress on the cardiovascular system. Listen in this week as Dee discusses a study showing how drinking a special kind of cacao drink may be the antidote to the cardio impacts of high stress and high fat meals.Reference:Baynham, R., Veldhuijzen van Zanten, J. J. C. S. V., & Rendeiro, C. (2024).

Why do people regain weight more quickly than expected after successfully losing it? Research shows that once someone has been overweight or obese, the genes in their fat cells undergo changes, creating a "memory" of the overweight state. This makes it easier for the body to return to that state. Listen in this week as Dee discusses this fascinating research, and what it means for long term weight loss maintenance.Reference:Hinte, L. C., Castellano-Castillo, D., Ghosh, A., Melrose, K., Gasser, E., Noé, F., Massier, L., Dong, H., Sun, W., Hoffmann, A., Wolfrum, C., Rydén, M., Mejhert, N., Blüher, M., & Von Meyenn, F. (2024).

There is scant scientific evidence that compounds found in nightshade vegetables—such as tomatoes, potatoes, peppers, and eggplants—aggravate the pain and inflammation of arthritis. However, some people with arthritis feel that eating nightshades make their condition worse...and decades of research by a horticulture professor at Rutgers University may explain why. Listen in this week as Dee dives into the science behind the connection and examines whether nightshades truly contribute to inflammation and joint pain. References:Childers N.F., & Margoles M.S.

The FDA required food manufacturers to remove artificial trans fats from their products by June 18, 2018, due to their negative impact on health. Despite the ban, consumers should still be cautious of foods containing trans fats due to ingredients like mono- and diglycerides, which are not regulated as trans fats.
