How much exercise is too much?
The Boston Globe
Growing evidence shows that overdoing endurance training may damage your heart and shorten life expectancy. But don't hang up your running shoes and wetsuits just yet. Dr. Paul Thompson has run 29 Boston Marathons over the past four decades — he finished 16th in 1976 — but has also spent a good part of his career as a cardiologist researching the detrimental effects that high-endurance training has on the heart.More

Athletic Business
Mary Helen Sprecher doesn't mind telling you that she has a smartphone, but she's not very smart about it. It has just enough apps to confuse her. But the other day she received notice of one app that is coming soon, and it sounds like it could be just great for the fitness industry. All the creators are looking for is a little local fitness expertise in developing it. It's called Localeikki and when it's up and running, it will be a national database of recreation locations that are publicly accessible and locally recommended. More

The downside of a vegetarian diet
Men's Health
It's not always easy going green. A plant-based diet may leave you lacking in vitamin B12, finds a new research review in the Journal of Agricultural and Food Chemistry. B12 is created by a particular type of bacteria that's mainly found in the digestive tracts of animals, which means foods like milk, eggs, meat and fish are the major dietary sources of the vitamin.

Making the case for eating fruit
The New York Times
Experts agree that we are eating too much sugar, which is contributing to obesity and other health problems. But in the rush to avoid sugar, many low-carb dieters and others are avoiding fruits. But fresh fruit should not become a casualty in the sugar wars, many nutrition experts say. Dr. David Ludwig, the director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital, said that sugar consumed in fruit is not linked to any adverse health effects, no matter how much you eat.More

He diets, she diets: More weight-loss plans target men
The Wall Street Journal
Weight-loss companies are becoming savvier about getting men to go on a diet. Men and women diet and lose weight differently, research has shown. Men often go for diets with a simple message — eat this, avoid that — and don't care about the ins and outs of nutrition science as much as women do, weight-loss experts say. More

Several studies have lauded the anti-aging effects of resveratrol, an antioxidant found in grape-based products like red wine. A new study, however, suggests the compound could have some drawbacks.More

Bodybuilding steroids don't belong in vitamin products
Forbes
Consumers often expect vitamins to work miracles for their health. But if you're a woman taking a vitamin B supplement, the last things you might expect are your voice growing lower, your hair thinning out or growing oddly, and your menstrual cycle stopping. That's why the U.S. Food and Drug Administration issued a warning that a B vitamin product sold from a one-woman Long Island, N.Y., supplement company contained two anabolic, or bodybuilding, steroid drugs.More

The truth about antioxidants
TIME
A new report shows antioxidants do not boost fertility as previously thought. It's not the first study to take the shine off the popular agents, which many people take in supplement form. In a review published in the Cochrane Library, researchers found that antioxidants did not increase women's chances of conceiving or having a baby, which wasn't surprising, given that the quality of trials linking fertility and antioxidant supplements, say the scientists, was low.
