People taking 20 or 30 bone meal tablets every day as a calcium supplement may be giving themselves lead poisoning, a researcher said Friday. The bone meal is safe at normal doses, but some contains minute amounts of lead that could accumulate in the body with so-called "megadoses" taken by many vitamin enthusiasts, said Dr. Badi Boulos of the University of Illinois School of Public Health. "If people are taking the normal two or three tablets a day, we're not concerned," Boulos said.

State Atty. Gen. Dan Lungren settled with makers of calcium supplements and antacids to reduce their lead content--an agreement that consumer advocates called inadequate and unsafe. Lungren said eight manufacturers, including the makers of Rolaids, DI-GEL and Os-Cal, had agreed for the first time to limits on lead, a substance that has been linked to birth defects.

Add one more to the long list of ills associated with coffee drinking. Researchers at UC San Diego report today in the Journal of the American Medical Assn. that women who drink more than two cups of caffeinated coffee per day suffer a loss of bone density that can lead to bone fractures in later life. Scientists have suspected such a link for several years, but the report provides the strongest evidence of its existence.

Not milk? Choosing milk for your morning cereal or coffee used to be pretty simple: skim, low-fat or whole. These days, though, market shelves and refrigerators are crowded with an array of alternatives: soy, almond, rice, hemp and more. While some people opt for these beverages because they're vegan, they have allergies or because they're lactose intolerant, the beverages are increasingly popular for another reason too. "We're all being encouraged to eat a more plant-based diet, and some of these products fit that category," says Andrea Giancoli, a spokeswoman for the Academy of Nutrition and Dietetics and a policy analyst at the Beach Cities Health District Blue Zones Project in Hermosa Beach, an initiative to develop healthier communities.

A team of Harvard researchers may have discovered a new way to ward off the red, itchy rash caused by allergies to nickel. All it takes is a dab of topical cream, according to research published online Sunday in the journal Nature Nanotechnology. Thirty million to 45 million people -- more than 10% of the U.S. population -- are sensitive to nickel found in common objects including jewelry and coins, the paper reported. Among the sufferers: study lead author Jeffrey M. Karp of Harvard's Brigham and Women's Hospital in Boston, a nanoparticles specialist who sought a way to treat the irritating allergy.

In a surprising discovery, UCLA researchers have found that atherosclerosis, better known as hardening of the arteries, may arise in part through the formation of bone in the arteries. The finding, reported today in the Journal of Clinical Investigation, could open the door to new therapies to prevent atherosclerosis, which is treated by controlling intake of cholesterol and fats, said Dr. Linda Demer, associate chief of cardiology at the UCLA School of Medicine.

Question: You have mentioned that water hardness can affect the natural pigments in food and result in color changes. Can you explain what is meant by water hardness? Answer: Hard water is simply water that contains natural salts. There are two types of hard water. In one, called "temporarily hard," the calcium, magnesium and iron bicarbonate are precipitated when water is boiled. Over a long period of time, deposits of these mineral salts build up.

For 19 years, Anaheim-based ICEE-USA has grown steadily even though it ignored diversification, didn't bother to advertise and hardly changed its product--a carbonated drink of crushed ice drenched usually in one of two flavors. Now ICEE, which raised $3.2 million in an initial public offering two years ago, is poised to expand in some areas it has long shunned.

A slow-release sodium fluoride compound, supplemented with calcium, was recommended for approval as a new drug for osteoporosis by a Food and Drug Administration advisory committee on Friday. The recommendation by the FDA endocrinological and metabolic drugs advisory committee is not binding on the agency, but such recommendations generally are followed. If approved, the drug would be marketed by Mission Pharmacal, a manufacturer based in San Antonio.

Even a good night's sleep doesn't totally compensate for many weeks of sleep loss. And it's the late-night period when the accumulation of sleep loss may be most apparent. Researchers at Brigham and Women's Hospital examined the effect of weeks of insufficient sleep on performance. They scheduled nine healthy volunteers to live for three weeks on a schedule consisting of 43-hour periods in which they were awake for 33 of those hours. That equals about 5.6 hours of sleep for every 24 hours.
