Researchers at Harvard University say America's obesity epidemic won't plateau until at least 42 percent of adults are obese, an estimate derived by applying mathematical modeling to 40 years of Framingham Heart Study data.

According to a new study from the Journal of Bone and Joint Surgery (JBJS), patients with acute plantar fasciitis who perform manual plantar fasciitis stretching exercises, as opposed to shockwave therapy, had superior results and higher patient satisfaction.

Researchers for the first time have shown that drinking beet juice can increase blood flow to the brain in older adults -- a finding that could hold great potential for combating the progression of dementia. The research findings are available online in Nitric Oxide: Biology and Chemistry, the peer-reviewed journal of the Nitric Oxide Society and will be available in print soon.

Researchers have identified a hormone produced and secreted by the liver as a previously unknown cause of insulin resistance. The findings, in the November issue of Cell Metabolism, a Cell Press publication, suggest a new target for the treatment of insulin resistance and type 2 diabetes, the researchers say.

Black raspberries are highly effective in preventing colorectal tumors in two mouse models of the disease, according to a University of Illinois at Chicago study. The findings are published in the November issue of Cancer Prevention Research.

Statistics from the Centers for Disease Control and Prevention (CDC) rank mortality related to chronic liver disease and cirrhosis as the 12th most common cause of death in adults in the U.S. Using a modified definition that includes diseases such as viral hepatitis, liver cancer and obesity-related fatty liver disease (liver diseases), Mayo Clinic-led researchers have found that liver-related mortality is as high as fourth for some age groups, and eighth overall.

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the central nervous system.

People who are physically fit and active have fewer and milder colds, indicates research published online in the British Journal of Sports Medicine. The...

One of the many advantages of maintaining a normal body weight is having healthy fat, which in turn supports a healthy heart. Fat tissue is increasingly seen as more than just a storage depot -- it's also an active secretory organ that normally produces high levels of a cardioprotective hormone called adiponectin.

Sex hormones may be the biological reason why men are at greater risk than women for destructive periodontitis, an infection of the gums, according to researchers at the University of Maryland Dental School.
