Earlier this week, researchers reported that skipping breakfast was linked to heart disease. A few days later comes word that skipping breakfast could be a good weight-loss strategy because people don't make up for all those calories later in the day. Should we tear our hair out in frustration? Or cozy up to the scrambled eggs? “I'm very concerned about that. We in nutrition seem to put out contradictory diet messages,” said David Levitsky, a Cornell professor of nutritional sciences and psychology and the senior author of the breakfast and calories study.

People tend to think of heart disease as a scourge of modern life, brought on by vices such as greasy fast food, smoking and the tendency to be a couch potato. But 21st century CT scans of 137 antique mummies gathered from three continents show that hardened arteries have probably plagued mankind for thousands of years - even in places like the Aleutian Islands, where hunter-gatherers subsisted on a heart-healthy marine diet and occasional snacks of berries. Fully a third of the mummies examined - who lived in the American Southwest and Alaska as well as Egypt and Peru as much as 5,000 years ago - appeared to have the same vascular blockages that cause heart attacks and strokes in Americans today.

It's no surprise that someone who has never smoked, who eats a Mediterranean diet and keeps a normal weight and who exercises regularly is healthy. How healthy? Chances of death from all causes is reduced by 80% over eight years. Pretty healthy. Those four healthy behaviors also protected against heart disease and the buildup of calcium deposits in the arteries, the researchers said. Those are the results of a multiyear study of more than 6,000 people led by Johns Hopkins University researchers and published online Monday in the American Journal of Epidemiology.

African American adults who were counseled to eat more produce and get more exercise as ways to reduce their chances of getting cancer and heart disease ate more fruit over the course of a month, researchers said. But they didn't exercise or up their consumption of vegetables, according to the work presented Wednesday at the American Assn. for Cancer Research meeting in Anaheim. The work was looking at the notion that a greater effect could be achieved if people understood that one risky behavior - a poor diet, for instance - is associated with the chance of developing multiple diseases, said Melanie Jefferson of the Medical University of South Carolina, the lead researcher.

In a finding certain to put new pressure on the purveyors of sugary foods and drinks, a worldwide analysis shows that regardless of its effect on obesity, the ebb and flow of sugar in a country's diet strongly influences the diabetes rate there. The new study provides compelling evidence that obesity isn't driving the worldwide pandemic of Type 2 diabetes as much as the rising consumption of sugar - largely in the form of sweetened sodas, experts said. Increases in sugar intake account for a third of new cases of diabetes in the United States and a quarter of cases worldwide, according to calculations published Wednesday in the journal PLOS ONE. In the 175 countries studied, a 150-calorie daily increase in the availability of sugar - about the equivalent of a can of Coke or Pepsi - raises the prevalence of Type 2 diabetes by 1.1%, a research team from Stanford University and UC San Francisco found.

The prognosis for Alzheimer's patients nowadays is still not good. Cognex, the one drug approved to treat the condition, only relieves symptoms. But, according to Carl W. Cotman, a prominent psychobiologist who directs UC Irvine's research into Alzheimer's, efforts toward understanding the disease "are going like gangbusters. It's an amazing rate of progress." Drugs that may slow the disease are being tested.

Paul W. Ewald's best thinking started with an attack of diarrhea on a field trip to Kansas. A zoologist, he was studying the social habits of sparrows. But during that ordeal 24 years ago, he had time to ponder other things: Was his personal predicament simply the havoc of a germ bent on spreading itself around? Or was his body trying to flush away the germ? Was this the evolutionary adaptation of an invader or the evolved human defense against it?

Here is a glossary of terms frequently used in discussions of cardiovascular disease and risk factors for that illness. Also included are definitions for a variety of the fiber foods often mentioned in relation to this disease and its prevention. Atherosclerosis: A disease that begins early in life with the formation of cholesterol-containing plaque or fatty streaks on the inner walls of the arteries, eventually narrowing them and inhibiting blood flow.

Scientists have linked cardiovascular disease to an age-related breakdown of telomeres, repetitive strings of DNA on the ends of chromosomes. Every time a cell divides, a bit of the telomere is lost. Ultimately, when all the telomere is gone, the cells are unable to divide. Previous research has shown that cancer cells are able to prevent the telomeres from being shortened, and are thus able to continue dividing indefinitely. A team from Geron Corp. reports in the Proceedings of the National Academy of Sciences that blood vessel cells involved in atherosclerosis have shortened telomeres, suggesting that they have prematurely aged for an as-yet-unknown reason.
