Breast Cancer Increasing Among Men
Although breast cancer in men is still a
rarity, the incidence is increasing, according to a study published in the May 24, 2004, online edition of Cancer. Using data from
the National Cancer Institute’s, “Surveillance, Epidemiology, and End Results 1973–1998” database, researchers found that male breast cancer rose from 0.86 per 100,000 men in 1973 to 1.08 in 1998. Men also had a higher median age at diagnosis and were more likely to have lymph-node involvement.
With so much news about the obesity epidemic plaguing today’s kids, researchers recently set out to discover if there has been an increase in the number of cases of metabolic syndrome in this population. According to the American Heart Association (AHA), metabolic syndrome is a constellation
of medical conditions, such as diabetes and obesity, that are thought to be caused by insulin resistance or glucose intolerance. The AHA estimates that approximately 20%–25% of American adults suffer from this condition.
Women are at unique risk for certain nutrition-related diseases and conditions. Many of these diseases and conditions are caused by unhealthy lifestyle behaviors that may be preventable if women are given correct advice and information.

Fortifying grain products with folic acid was originally intended to reduce the incidents of birth defects.

Men with high levels of adiponectin, a protein hormone pro- oduced and secreted by fat cells, are less likely to have a heart
attack, according to a study published in the April 14, 2004, issue
of the Journal of the American Medical Association (2004; 291 , 1730–7). Adeponectin is thought to prevent fats from accumulating in arteries and may also reduce inflammation; although fat cells produce the hormone, obese people have lower levels of it.
A little goes a long way when training older adults with lower-extremity osteoarthritis, according to
a study in the April 2004 issue of The Gerontologist (2004; 44 , 217–28). Researchers looked at the impact of a low-cost, multicomponent physical
High cholesterol is a dangerous contributor to coronary heart disease. The National Cholesterol Education Program (NCEP) Guidelines from the National Institutes of Health state that a total-cholesterol level of 240 milligrams per deciliter (mg/dl) or higher indicates an elevated risk of having a heart attack. Optimally, LDL, the “bad” cholesterol, should be 100 mg/dl or below for high-risk individuals (those with cardiovascular disease [CVD], diabetes or a 20 percent [%] or greater chance of suffering a heart attack or dying from CVD in the next 10 years).
More evidence is stacking up against dehydroepiandrosterone (DHEA). Over-the-counter DHEA capsules and creams have been hyped to battle everything from low sex drive to heart disease and Alzheimer’s. Many athletes and bodybuilders also use the supplement in their efforts to gain muscle mass.
