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.

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.

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.

Cutting the amount we drink to just over half a unit a day could save 4,600 lives a year in England, according to a modelling study by Oxford University researchers published in the journal BMJ Open. Scientists have carried out a complex analysis in an attempt to determine the "optimal" level of alcohol consumption that is associated with the lowest rates of chronic disease in the UK.

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.

A major new study claims the pricey supplement TA-65 may turn back the clock, all the way down to our DNA—but many scientists are brushing it off as snake oil. Thea Singer investigates. In an era of seemingly magical technology, the notion that scientists could develop a pill that might slow the aging process doesn’t seem that far-fetched.

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.

Water could change the way we eat. That's the conclusion of new research by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. Their findings appear online this week ahead of regular publication by the journal Appetite.

Undertaking regular jogging increases the life expectancy of men by 6.2 years and women by 5.6 years, reveals the latest data from the Copenhagen City Heart study presented at the EuroPRevent2012 meeting. Reviewing the evidence of whether jogging is healthy or hazardous, Peter Schnohr told delegates that the study's most recent analysis (unpublished) shows that between one and two-and-a-half hours of jogging per week at a "slow or average" pace delivers optimum benefits for longevity.

Researchers have identified key genes that switch off with aging, highlighting them as potential targets for anti-aging therapies. Researchers at King's College London, in collaboration with the Wellcome Trust Sanger Institute, have identified a group of 'aging' genes that are switched on and off by natural mechanisms called epigenetic factors, influencing the rate of healthy aging and potential longevity.

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.

Collaborations between Johns Hopkins and National Taiwan University researchers have successfully manipulated the life span of common, single-celled yeast organisms by figuring out how to remove and restore protein functions related to yeast aging.
