A New MED Diet Pyramid: All About Plant Foods

Dear readers,

The MED diet is always a favorite and backed by research, but a new MED food pyramid goes back to its original roots: a largely plant-based diet with EVOO, de-emphasizing animal foods. Then, a systematic review suggests higher EVOO diets improve endothelial function. Finally, for food, a plant-based diet creates an “alkaline way” or tide that lowers inflammation and promotes weight loss in an RCT in type 1 diabetics. It is always good to work out, but late-night workouts may interfere with sleep. Dietary niacin is associated with lower mortality in COPD patients, reassuring. Loneliness is a risk factor for heart disease. I always ask patients about this. Vitamin C promotes collagen formation, and it assists skin health. Finally, data show that heart attacks are way down, but heart deaths are not, as heart failure and arrhythmia deaths have been on the rise. We have a lot of work to do.

Be well,

Joel Kahn, MD, FACC

    •  A new study from WHOOP provides the most comprehensive real-world evidence to date on how evening exercise intensity and timing affect sleep and recovery. Analyzing data from 14,689 WHOOP members across more than 4 million nights, researchers have found that high-strain workouts within four hours of bedtime can meaningfully disrupt sleep onset, reduce total rest, and impair cardiovascular recovery.

      The study entitled Dose-response relationship between evening exercise and sleep was published in Nature Communications, and was done in collaboration with Monash University in Australia and Harvard University.
