Cocoa Flavonoids & Avocados May Protect Against Cardiovascular Death

The COSMOS study, sponsored by Pfizer and Mars Candies, looked at the effect of Cocoa flavonoids on cardiovascular events such as a heart attack, cardiovascular deaths and consumption of cocoa flavonoids and green tea. There were 21,442 U.S. adults in the study followed for 3.6 years.

The experimental group received cocoa and green tea. While there were just as many cardiovascular events in the study group as in the control group, the number of deaths dropped by 27%. The study was published in the American Journal of Clinical Nutrition and was commented on by David Rakel, MD, FAAFP in the online medical journal Primary Care.

Flavonoids are found in dark colored grapes and berries, apples, pears, green tea and dark chocolate. If you eat 1/4 of a dark chocolate bar you are getting the same dosage the experimental group was given in this study.

Dr. Rakel suggested that Flavonoids maintain the flexibility of the blood vessels as we age. Recent related studies indicate a handful of blueberries or cranberries daily have similar effects. A glass of red wine with a square of dark chocolate and some dark berries suddenly sounds like a healthy snack!

Avocados apparently convey cardiovascular protection as well. In a study published in the March 30, 2022 Journal of the American Heart Association researchers followed 110,00 adults for 30 plus years and found that those who consumed two or more servings of avocado a week had a much lower risk of developing cardiovascular disease then non consumers.
