New study shows healthier food choices could dramatically decrease environmental costs of agriculture

As cities and incomes increase around the world, so does consumption of refined sugars, refined fats, oils and resource- and land-intense agricultural products such as beef. A new study led by University of Minnesota ecologist David Tilman shows how a shift away from this trajectory and toward healthier traditional Mediterranean, pescatarian or vegetarian diets could not only boost human lifespan and quality of life, but also slash greenhouse gas emissions and save habitat for endangered species.

ANN ARBOR — Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. (more…)

Offspring of Older Fathers May Live Longer

If your father and grandfather waited until they were older before having children, you might experience life-extending benefits. Biologists assume that a slow pace of aging requires that the body invest more resources in repairing cells and tissues.

A new study suggests that our bodies might increase these investments to slow the pace of aging if our father or grandfather waited until they were older before having children.

“If your father and grandfather were able to live and reproduce at a later age, this might predict that you yourself live in an environment that is somewhat similar — an environment with less accidental deaths or in which men are only able to find a partner at later ages,” said Dan T.A. Eisenberg, lead author of the study published June 11 in the Proceedings of the National Academy of Sciences. (more…)

Optimism Cures Heart Diseases

Heart patients with an optimistic outlook are more likely to be healthier down the road and survive longer than those with less rosy views, new research suggests.

A study reported this week in the Archives of Internal Medicine that followed 2,800 heart patients found that those with more positive attitudes about their recovery had about a 30 percent greater chance of survival after 15 years than patients with pessimistic leanings. (more…)

Intelligence and Personality May Predict Illness and Death

Do smarter people live longer and better lives? Are certain personality types more prone to premature death than are others? As our population continues to age in dramatic numbers, these questions become increasingly relevant. A new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, provides an overview of research on possible associations between intelligence and personality traits and various health outcomes.

Although there is not much evidence to date that links intelligence with cancer, low intelligence has been shown to be related to increased risk of hospital admission and death due to cardiovascular disease. In addition, lower intelligence is associated with a greater incidence of accidents and risk of death by homicide than is higher intelligence. (more…)

Yes Virginia, People Who Eat Healthier Really Do Live Longer

COLLEGE PARK, Md. — Medical and dietary experts have long recommended healthy eating habits. Now, on the eve of one of our most calorically indulgent holidays, a new study provides some of the strongest evidence yet that those with healthy diets really do to live longer and feel better.

In a study published in the January 2011 issue of the Journal of the American Dietetic Association, researchers from the University of Maryland and five other institutions found that diets favoring “healthier foods” were associated with significantly reduced mortality when compared to diets high in fat and sugar. Their study investigated the associations of dietary patterns with mortality through analysis of the eating patterns of over 2500 adults between the ages of 70 and 79 over a ten-year period. (more…)
