Bring on the Lard

1 Saturated Fats Don't Cause Heart Disease

Dietary saturated fat, such as that in meats and full-fat dairy products, are not associated with a higher risk of coronary heart disease, stroke or cardiovascular disease, according to a new study published in the American Journal of Clinical Nutrition. Subjects in previous studies whose risk of heart disease was reduced when they cut down on their consumption of saturated fat may have actually been benefiting from an increase in polyunsaturated fat consumption or an increase in certain kinds of carbohydrates. This new study is a meta-analysis that reexamined 21 previous studies on the subject.

The Grandparents Can Dance Again

2 Ankle Replacements Joining Hips and Knees

Widespread adoption of hip and knee replacement surgery is allowing the elderly and the obese to continue walking long enough to blow out their ankles. The New York Times reports on the increasing use of artificial ankle joints. More complex than a hip or knee replacement, the ankle replacement is just now coming into its own. Among the benefits of ankle replacement are the ability to walk without pain and without an altered gait, climb a ladder, play soccer with the grandkids, and dance at a grandchild's wedding, according to recipients of the high-tech implants. Complications? Slow healing, infection, and the occasional foot amputation.

Touch My Tummy

3 Denise Austin Aspires to be Jack LaLanne

Fitness guru Denise Austin was the fitness columnist for the Washington Post in the 1980s, and recently the current fitness columnist, Vicky Hallett paid Austin a visit in her Washington area home to check up on her. The 52-year-old Austin is still in great shape and aspires to be a lifelong fitness example just like 95-year-old Jack LaLanne, who gave Austin her start on television in 1981. LaLanne greats people with the line, "Feel my legs"; Austin, a mother of two children, has modified that to "Touch my tummy." Among other things, writer Hallett was able to get a peak into Ausin's refrigerator.

Children are Dosed by Weight

4 Antibiotic Dosages May be Inadequate for Obese

Researchers are questioning whether a one-size-fits-all policy for antibiotic dosages is appropriate in an age when body sizes are widely divergent, with particular growth at the obese end of the scale. Although it's common sense that dosages of antibiotics and other medicines for children vary by their size and weight, this is not usually the case with adults. An editorial in the current issue of the British medical journal The Lancet recommends that the medical community establish dosage policies for medications that take into account individual body mass. In particular, the increased prevalence of antibiotic-resistant diseases makes correct dosage more important.

Plastic Problems

5 FDA Says It Can't Regulate BPA

The Food and Drug Administration says it doesn't have the power to regulate bisphenol A, a chemical found in hard plastics and the lining of food containers -- including formula containers -- that has been potentially linked to breast and prostate cancer, obesity, diabetes and other health problems. The FDA recently reversed its feeling on the chemical, which it had previously deemed safe. The agency says it would take legislation to ban the chemical from baby bottles or food containers, and there's a worry that if the chemical were banned babies who rely on formula would be left without a healthy alternative.

Would Be Worth $50 Billion

6 Kraft Reaches Deal for Cadbury

Kraft Foods is said to have reached a tentative deal to buy British food conglomerate Cadbury for $19 billion in cash and stock. Those familiar with the negotiations said the deal could still fall apart, but if it goes through it would produce a huge international company that contains such brands as Oreo, Ritz, Trident Gum and Dairy Milk chocolate. The combined company would have more than $50 billion in revenue. Cadbury has long said it preferred to remain independent and the company rejected a previous buyout offer by Kraft. Some in Britain say the company's purchase will lead to a loss of as many as 30,000 jobs. Hershey had also been interested in the company but analysts say its unlikely that company will be able to match the proposed deal set out by Kraft.

Get Off Your Butt

7 Too Much Sitting Counteracts Exercise, Study Finds

Too much sitting may lead to lifestyle-related diseases and counteract the effects of moderate to vigorous exercise, according to scientific research conducted at the Karolinska Institute in Stockholm and reported in the British Journal of Sports Medicine. According to a recent study, women who increased their sitting time by one hour per day saw a rise in the rate of metabolic syndrome by 26 percent, despite the amount of moderate to intensive exercise they performed. Further research is needed to ascertain if there is a causal link between a sedentary lifestyle and these diseases. For now, the studies suggest that people should not only exercise regularly but should also avoid sitting in one place for too long.
