In an observational study of 1.3 million women, excess weight was linked to an increased risk of strokes caused by blood clots but a lower risk of strokes caused by bleeding. 

The view that calories are calories regardless of their source has been shown to be outdated. Foods with a low glycemic index are better because they tend to raise blood sugar more slowly, and they are also more likely to be healthier foods overall. By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.

Nuts are a good source of plant fats and protein, but they are high in calories. It’s a good idea to limit nut consumption to 1 ounce per day.

Q. I love dried fruit and thought it was healthy. But I hear that you gain a lot of weight eating dried fruit, which is not healthy. What's the truth?

A. The truth is that the actress and comedian Mae West was wrong when she allegedly said "Too much of a good thing ... can be wonderful!"

It's a good reminder for all of us that too much salt in the diet is risky for health. How much is too much? "It's controversial, although I don't think anyone is in favor of unlimited salt intake," says Dr. Randall Zusman, a cardiologist with Harvard-affiliated Massachusetts General Hospital.

A large international study published Aug. 20, 2016, in The Lancet suggests that an unhealthy body mass index increases the risk of early death.

Teens don’t exercise enough, and with a third of U.S. adults classified as obese, it’s important that exercise is encouraged in children and teens. Starting healthy habits when they’re young keeps kids healthy into adulthood. Studies show that obese adults rarely lose the weight, so it’s better to keep the weight off in the first place. A lot has to do with our biology but also our lifestyle, and we can change the latter. So let’s get our children and teens moving.

Being overweight can lead to a host of health problems, from high blood pressure and heart disease to arthritis, gallstones, and sleep apnea. It can also contribute to foot problems in two ways.

First, excess weight contributes to the misery of common structural problems such as heel pain and arthritis. Any foot ailment is more painful the more weight you put on it. Second, excess pounds increase your chances of developing atherosclerosis, poor circulation, and diabetes — all of which can damage your feet.
