Move over, omega-3s . There's a new fatty acid in town that might make you healthier. Something more closely associated with creamy pleasure than with fish burps. Trans-palmitoleic acid, a fatty acid that circulates at higher levels in the blood of those who consume lots of full-fat dairy products, may protect against diabetes, according to a study published Monday in the Annals of Internal Medicine . That surprising finding may fly in the face of much nutritional advice that warns us against consuming too much whole milk, cheese or other sources of animal fat. But it comes from a study of 3,736 adults participating in the long-running Cardiovascular Health Study . It also proceeds from a suspicion that researchers have had for a while, but found difficult to prove: that the fatty acid palmitoleate, which humans produce in their liver and fat, and consume in dairy fats, may play a complex role -- beneficial and harmful -- in regulating metabolism . By measuring just the palmitoleate that came from consumption of dairy fats, researchers were able to discern the side of this fatty acid that may contribute to good health.

Here's another way in which exercise may help a person avoid an early death: It fights insulin resistance syndrome, which may affect millions of American. "My guess is 10% to 25% of the population is insulin resistant," said Dr. Robert Sherwin, a professor at Yale School of Medicine and president-elect of the American Diabetes Assn. There are no statistics on exactly how many people have the condition, he said.

Texas researchers have found a naturally occurring hormone that can extend the lifespan of mice by as much as 30%, a discovery that opens a new avenue of research into human longevity. The hormone has a drawback, however: It decreases fertility and increases susceptibility to diabetes, the team reported Thursday in the online edition of the journal Science.

Strength training mostly consists of concentric exercises (when the muscles shorten to lift something, as in lifting a weight to do a bicep curl) and eccentric exercises (when the muscles lengthen to lower something). But could one action provide more benefits than the other? A study found that half an hour of eccentric exercise a week boosted muscle strength and lowered insulin resistance more than concentric exercise. Twenty women were randomly assigned to an exercise group that did either concentric or eccentric movements once a week for eight weeks.

Exercise as simple as climbing stairs can help at-risk children of diabetics process sugar better and avoid their parents' disease. Moderate aerobics helps their muscle cells accept sugar and either use it or store it as the muscle fuel glycogen, according to the report in the New England Journal of Medicine. "The bottom line is, with exercise we can improve significantly or reverse this abnormality," said Dr. Gerald I.

Just a few nights of bad sleep is enough to throw the body's metabolism into disarray, according to a new study published Monday in the journal Annals of Internal Medicine. The study shows that getting four hours of sleep a night for four nights made healthy people's bodies resistant to insulin - a condition that is a common precursor of weight gain, diabetes and other serious health problems. In a healthy body, when you take in sugar, insulin is released from the pancreas and travels throughout the body, signaling to cells that they should absorb some of that new glucose.
