Exercise advice for couch potatoes usually goes like this: doing something is better than doing nothing. Turns out that might be true--people who do even a little regular exercise may have lower risk of heart disease than people who never leave the sofa. Researchers did a meta-analysis of 33 studies looking at the effects of exercise on coronary heart disease among people who were active or sedentary to see if they could quantify how much exercise was needed to show any benefits. The 2008 Physical Activity Guidelines for Americans, which recommend a minimum of 150 minutes a week of moderate exercise for health benefits, were used as a measure.

Drinking and driving is never a good idea, and neither is smoking pot and driving, a study finds. People who smoke marijuana within a few hours of getting behind the wheel may be almost twice as likely to cause an accident compared with those who are sober. A review of nine studies on pot smoking and car crashes was done by researchers from Dalhousie University in Nova Scotia, Canada. The authors wrote that previous studies have been somewhat inconclusive about marijuana's effect on automobile collisions, some showing it linked with a higher risk of crashes, and some showing a lower risk.

The Mediterranean diet has been linked to a host of health benefits, including a lower risk of heart disease , cancer and diabetes . A study finds that the diet may also be associated with a decreased chance of small vessel damage in the brain.

Eating food containing trans fats and saturated fats could contribute to depression, scientists reported Wednesday. Researchers in Spain followed 12,059 people over six years, analyzing their diets, lifestyles and medical problems. The people who ate the most trans fats, which are commonly found in pastries and fast food, had a 48% increased risk of depression compared with people who did not eat trans fats. Individuals who ate a lot of polyunsaturated fats -- a healthier type of fat that is found in olive oil, for example -- had a lower risk of depression.

If you're thinking of jumping on the low-carb diet bandwagon or have already jumped, consider this: new research findings reveal that vegetable-based low-carb diets may be linked with lower overall mortality rates and lower death rates from cardiovascular disease and cancer. The study used data from the Nurses' Health study and included 85,168 women age 34 to 59 and 44,548 men age 40 to 75 who were on low-carb diets that derived protein from animal or plant sources. The women were followed from 1980 to to 2006, and the men from 1986 to 2006.

The audience wasn't happy. Its members — private citizens, healthcare professionals and advocates for the elderly — had gathered to hear a report on how to prevent Alzheimer's; instead, they were told that, in fact, nothing has been proved to keep the disease at bay. "We're not trying to take anyone's hope away," said report co-author Dr. Carl C. Bell, a professor of psychiatry and public health at the University of Illinois, Chicago,...

Sweet potatoes are often regarded as a healthier alternative to the white potato, which has been recently maligned as “Public Enemy No. 1” in America’s battle of the bulge. Some would even say that sweet potatoes are to white potatoes what brown rice is to white. But in a head-to-head comparison, these two tubers are seemingly very similar. In a 100-gram portion, the white potato has 92 calories, 21 grams of carbs, 2.3 grams of dietary fiber, 2.3 g of protein and 17% of the recommended daily value of vitamin C. The same amount of sweet potato, on the other hand, has 90 calories, 21 grams of carbs, 3 grams of fiber, 2 grams of protein, 35% of the recommended daily value of vitamin C and 380% of the daily recommended value of vitamin A. Importantly, both have won Vegetable of the Month designations from the Centers for Disease Control and Prevention.

S&P said the withdrawal of Vivendi from the firm's trigger list won't lift the company's ratings.

If you take statins to lower your cholesterol, you may also be lowering your risk of death from cancer, new research suggests. A report published in Thursday's edition of the New England Journal of Medicine is one of a number of recent papers suggesting that statins not only limit the growth of cancer cells but also make them more vulnerable to certain therapies. "Regular statin use before and after a diagnosis of cancer could theoretically reduce cancer-related mortality," wrote study leader Sune F. Nielsen, a biochemist at the University of Copenhagen who based his findings on an analysis of more than 5.5 million people in Denmark.
