The latest research supports the conclusion that, for most adults, consuming up to 400 mg of caffeine a day (or up to five 8-ounce cups of caffeinated coffee per day) is safe and appears to be linked to a lower risk of cardiovascular disease for some individuals. However, higher doses of caffeine, such as levels found in energy drinks including energy shots, may cause cardiovascular harm, according to a new American Heart Association scientific statement, "Caffeine and Cardiovascular Disease," published today in the journal Circulation. https://medicalxpress.com/news/2026-07-coffee-heart-health-cups-caffeinated.html Mon, 20 Jul 2026 05:00:01 EDT news703505779 New research published in The American Journal of Preventive Medicine and presented at this year's International Congress on Obesity (ICO 2026), hosted by the World Obesity Federation (WOF) in Mexico City, Mexico (July 15–17), suggests that 23%-38% of all cardiovascular deaths and 23%-37% of all cases of cardiovascular disease (coronary heart disease and stroke) are attributable to ultra-processed food (UPF) consumption. https://medicalxpress.com/news/2026-07-heart-deaths-disease-due-ultraprocessed.html Thu, 16 Jul 2026 11:20:11 EDT news703407563 The common rationale for drinking water at meals is that it physically stretches the stomach, triggering fullness so you don't eat too much.
