It is widely known that a healthy lifestyle that includes not smoking, limiting alcohol intake, and maintaining a proper weight reduces disease risk. In the journal PLoS Medicine, Wei Zheng, M.D., Ph.D., M.P.H., and colleagues at Vanderbilt University Medical Center now report results from a large study quantifying the impact of combining healthy lifestyle factors.

Standing up more often may reduce your chances of dying within three years, even if you are already physically active, a study of more than 200,000 people published in Archives of Internal Medicine shows. The study found that adults who sat 11 or more hours per day had a 40% increased risk of dying in the next three years compared with those who sat for fewer than four hours a day. This was after taking into account their physical activity, weight and health status.

For years the Mediterranean diet has been associated with a lesser chance of illness and increased well-being. A new study has now linked it to mental and physical health too. The Mediterranean diet, which is characterised by the consumption of fruit, vegetables, pulses (beans, peas, chickpeas and lentils etc.) , fish, olive oil and nuts, has been proven to be beneficial to the health in terms of a lesser chance of chronic illness and a lower mortality rate.

Despite modest gains in lifespan over the past century, the United States still trails many of the world's countries when it comes to life expectancy, and its poorest citizens live approximately five years less than more affluent persons, according to a new study from Rice University and the University Colorado at Boulder.

Older people with large waistlines have a higher mortality rate than those with a slim waistline. This was shown in a new study conducted by the Sahlgrenska Academy at the University of Gothenburg, Sweden. Coherent research has shown that being underweight is considerably more dangerous for the elderly than being overweight. A study at the Sahlgrenska Academy, University of Gothenburg, has now shown that large waist circumference is associated with the risk of increased mortality in the elderly.

Researchers have discovered a new mechanism controlling aging in white blood cells. The research, published in the September issue of the Journal of Immunology,...

The numbers are, well, depressing: More than 2 million people age 65 and older suffer from depression, including 50 percent of those living in nursing homes. The suicide rate among white men over 85 is the highest in the country -- six times the national rate. And we're not getting any younger. In the next 35 years, the number of Americans over 65 will double and the number of those over 85 will triple.

Older adults who drank coffee -- caffeinated or decaffeinated -- had a lower risk of death overall than others who did not drink coffee, according a study by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and AARP. Coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was not seen for cancer.

In the largest study to date of the Arthritis Foundation's Tai Chi program, participants showed improvement in pain, fatigue, stiffness and sense of well-being. Their ability to reach while maintaining balance also improved, said Leigh Callahan, PhD, the study's lead author, associate professor in the University of North Carolina at Chapel Hill School of Medicine and a member of UNC's Thurston Arthritis Research Center.

Restricting the amount of time spent seated every day to less than 3 hours might boost the life expectancy of US adults by an extra 2 years, indicates an analysis of published research in the online journal BMJ Open.

When mice are given drinking water laced with a special concoction of amino acids, they live longer than your average mouse, according to a new report in the October issue of Cell Metabolism, a Cell Press publication. The key ingredients in the supplemental mixture are so-called branched-chain amino acids, which account for 3 of the 20 amino acids (specifically leucine, isoleucine, and valine) that are the building blocks of proteins.

The vegetables in salads are chock-full of important vitamins and nutrients, but you won't get much benefit without the right type and amount of salad dressing, a Purdue University study shows. In a human trial, researchers fed subjects salads topped off with saturated, monounsaturated and polyunsaturated fat-based dressings and tested their blood for absorption of fat-soluble carotenoids -- compounds such as lutein, lycopene, beta-carotene and zeaxanthin. Those carotenoids are associated with reduced risk of several chronic and degenerative diseases such as cancer, cardiovascular disease and macular degeneration.
