Research Suggests More Damaging Effects Of Endurance Exercise On The Heart

Dear Endurance Athletes,

Accept an apology in advance. You have endured so much from me.


Let’s at least start by agreeing that I can’t control the data.

Yes, you guessed it. There is unfortunately more bad news pertaining to the deleterious effects of endurance exercise on the human heart.

Again, I am sorry. Maybe re-phrasing the previous sentence will soften the blow. How about this: “Yet another study on endurance athletes suggests that exercise, like everything else in life, has an upper limit.”

Here goes, buckle up. Read more »

Taking Chocolate To Heart

darkchocolate Chocolate: The Newest Heart Healthy FoodIt’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 »

Heart Disease And Working Overtime

The European Heart Journal studied 6,000 British civil servants and followed them for 11 years. They found that working an extra 3 to 4 hours a day is associated with increased coronary heart disease.

The researchers controlled and adjusted for lifestyle, cardiac risk factors, and other factors that would skew the results, and still found that people who worked 3 to 4 extra hours a day had a 60 percent increase in risk for heart disease. Read more »

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
