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.

Taking calcium supplements increases the risk of having a heart attack, Swiss and German researchers reported Wednesday. The finding adds to the growing body of evidence that such supplements increase the risk to those who take them while providing only minimal benefits. The study is considered important because large numbers of people, especially elderly women, continue to take the supplements in hopes of minimizing loss of bone density. The body of evidence now seems to suggest that calcium consumed as part of a normal diet can, indeed, increase bone density and perhaps help lower blood pressure, but that supplements may be too risky for most people to take.

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.

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.

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.

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,...

Vivendi Universal faces reduced risk of running short of cash if its credit ratings are cut after renegotiating loans and repaying a $2.3-billion obligation, Standard & Poor's Corp. said. The world's second-largest media company said it has unused credit lines of $3.3 billion available after paying its dividend and buying the entertainment business of USA Networks Inc. 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.
