Taking Chocolate To Heart
It’s beginning to look like chocolate, especially dark chocolate, really and truly is a heart healthy snack, though only if it’s consumed in small quantities.
A delectable taste of this news came last spring, in the form of a study by German scientists which appeared in the European Heart Journal. It was a retrospective study of nearly 20,000 people, and it showed that folks in the highest quartile for chocolate consumption (meaning they consumed 7.5 grams of chocolate per day — the equivalent of 2 to 3 small squares of a Hershey bar), had lower blood pressure, a 27 percent lower risk of heart attack, and a 48 percent lower risk of stroke than those in the lowest quartile (about 1.7 grams per day).
Now, a new study in the journal Cardiovascular Pharmacology has lent credence to those findings by suggesting a mechanism through which chocolate reduces blood pressure. In the study, Ingrid Persson and colleagues at Linkoping University showed that dark chocolate inhibits the activity of the angiotensin-converting enzyme (ACE). This enzyme helps regulate fluids and salt metabolism in the body. It is the target of many well-known antihypertensive drugs including captopril, lisinopril and enalopril. Read more »
