University of Washington scientists have uncovered details about the mechanisms through which dietary restriction slows the aging process.   view more (2008-04-18)

Calorie restriction in non-human primates may prevent and reduce Alzheimer's disease neuropathology
A new study directed by Mount Sinai School of Medicine extends and strengthens the research that experimental dietary regimens might halt or even reverse symptoms of Alzheimer's Disease (AD).   view more (2006-09-18)

Calorie restriction may prevent Alzheimer's through promotion of longevity program in the brain
A recent study directed by Mount Sinai School of Medicine suggests that experimental dietary regimens might calm or even reverse symptoms of Alzheimer's Disease (AD).   view more (2006-06-15)

Researchers note differences between people and animals on calorie restriction
Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists at Washington University School of Medicine in St. Louis.   view more (2008-09-25)

New Lifespan Extension Genes Found
New genes tied to lifespan extension in yeast have been identified by researchers from UC Davis and Harvard Medical School.   view more (2005-10-03)

Calorie restriction does not appear to induce bone loss in overweight adults
Young adults who follow a diet that is low in calories but nutritionally sound for six months appear to lose weight and fat without significant bone loss.   view more (2008-09-22)

EFFECT OF DIET ON CANCER RISK (p 861)
A review in this week’s issue of THE LANCET assesses the research which has investigated possible links between diet and cancer. A familiar conclusion is reached-cancer risk can be reduced by eating a balanced diet (including the regular consumption of fresh fruit and vegetables), combined... view more (2002-09-11)

Picky eating potentially perilous for bats
Working in the Department of Ecology and Organismal Biology, Justin Boyles and Jonathan Storm examined the possibility of a link between dietary specialization and the risk of extinction for bats in Australia, Europe and North America.   view more (2007-07-25)

Dietary fat not linked to risk of stroke
Unlike heart disease, dietary fat does not seem to be associated with risk of stroke, finds a study in this week’s BMJ.   view more (2003-10-01)

Calorie restriction inhibits, obesity fuels development of epithelial cancers
A restricted-calorie diet inhibited the development of precancerous growths in a two-step model of skin cancer, reducing the activation of two signaling pathways known to contribute to cancer growth and development, researchers at The University of Texas M. D. Anderson Cancer Center report today at... view more (2008-04-15)

Researchers find link between food odors and lifespan in fruit flies
Researchers hoping to learn why organisms tend to live longer if their intake of calories is restricted have made a startling discovery - in fruit flies, just the smell of food can have a negative effect on longevity.   view more (2007-02-02)

High intake of dietary fiber not associated with reduced risk of colorectal cancer
In an analysis combining data from 13 studies, high intake of dietary fiber was not associated with reduced risk of colorectal cancer.   view more (2005-12-14)

Reduced body temperature extends lifespan in study from the Scripps Research Institute
"Our study shows it is possible to increase lifespan in mice by modest but prolonged lowering of core body temperature," said Bruno Conti, an associate professor at Scripps Research who led the study. "This longer lifespan was attained independent of calorie restriction."   view more (2006-11-03)

Consuming small amounts of caffeine when pregnant may affect the growth of an unborn child
Consuming caffeine at any time during pregnancy is associated with an increased risk of fetal growth restriction (low birth weight).   view more (2008-11-03)

Partners can help or hinder attempts at changing diet
For people trying to make a change in their diet, significant others generally play a positive and supportive role, but sometimes respond in negative ways, according to a study in the March/April Journal of Nutrition Education and Behavior (http://www.jneb.org/).   view more (2008-03-26)

Low-fat, high-carbohydrate diet not associated with weight gain in postmenopausal women
In a clinical trial of over 48,000 post-menopausal women, a low-fat diet that includes increased consumption of fruits, vegetables and whole grains is not associated with weight gain over an average of 7.5 years.   view more (2006-01-04)

Dietary fibre supplements may be harmful
Not all dietary fibre is as good for us as we have been led to believe, says an editorial in Gut. Instead of protecting us from colon cancer, writes Dr Robert Goodlad of the Imperial Cancer Research Fund, some fibre and fibre supplements could actually increase our risk of developing the disease,... view more (2001-04-10)

Large study shows low-fat diet has little effect on reducing risk of breast cancer
A major study that includes nearly 50,000 women followed over 8 years indicates that a diet low in fat, but high in fruit, vegetables and grains, does not significantly reduce the risk of breast cancer in postmenopausal women   view more (2006-02-08)

A high fat, low carbohydrate diet improves Alzheimer's disease in mice
Mice with the mouse model of Alzheimer's disease show improvements in their condition when treated with a high-fat, low-carbohydrate diet.   view more (2005-10-17)

Vitamin E may increase tuberculosis risk in male smokers with high vitamin C intake
Six-year vitamin E supplementation increased tuberculosis risk by 72% in male smokers who had high dietary vitamin C intake, but vitamin E had no effect on those who had low dietary vitamin C intake, according to a study published in the British Journal of Nutrition.   view more (2008-02-22)

Dietary fat itself not likely to cause breast cancer
A diet high in fat is not by itself likely to cause breast cancer, suggests a study in the Journal of Epidemiology and Community Health. But it is likely to deplete the body of an essential nutrient, a factor that is probably responsible for most cases of the disease, concludes the research. The... view more (2000-10-16)

Mouse Study: When It Comes To Living Longer, It's Better To Go Hungry Than Go Running
A study investigating aging in mice has found that hormonal changes that occur when mice eat significantly less may help explain an already established phenomenon: a low calorie diet can extend the lifespan of rodents, a benefit that even regular exercise does not achieve.   view more (2008-05-14)

New evidence finds no association between coffee consumption and risk of colorectal cancer
There is no association between coffee consumption and risk of colorectal cancer, finds new evidence in Gut, despite previous studies suggesting a protective effect of coffee consumption. This presumption may be premature, report the authors. Paul Terry and colleagues examined data from over 61,... view more (2001-06-14)
