For the first time, companies are required to back up their “gluten-free” claims with real numbers: for products to be labeled gluten-free, they can’t contain more than 20 parts per million (ppm) of gluten. That’s considered a safe level for those with celiac disease and gluten sensitivities. “Previous to this, there was no standard for the amount of contamination that could be in a product,” said Pam Cureton, RD, LDN, registered dietitian at the Center for Celiac Research at MassGeneral Hospital for Children....

When you have the flu, you can pass along your sickness to your kids and hubby…and apparently also to your poodle Puddles. Researchers from Oregon State University are investigating how common rare cases of “reverse zoonosis”—where humans pass on illnesses to animals—are.

Toe deformities are highly inheritable in (white) men and women of European descent, according to a study appearing in the May issue of Arthritis Care & Research. Almost 1,400 people enrolled in the Framingham Foot Study, averaging 66 years of age, underwent a foot exam between 2002 and 2008 to determine if they had bunions, hammer toes or plantar soft tissue atrophy, which is a breakdown of the fatty “cushion” under the ball of the foot....

Federal regulators failed to pursue recalls after they found cadmium-tainted jewelry on store shelves—despite their vow to do so, an Associated Press investigation shows. More than two years after the AP revealed that some Chinese factories were substituting cadmium for lead, the CPSC still hasn’t determined the extent of the contamination. Rings, bracelets, and pendants containing cadmium and marketed for preteen girls were purchased over the last year. (What else is lurking in your jewelry?...

Cholesterol itself isn’t harmful. In fact, the body produces this waxy substance daily to manufacture cell membranes, bile acids, vitamin D, and a variety of sex hormones. Serious problems can occur when cholesterol levels in the blood rise to unhealthy levels. We often talk about cholesterol as though it’s a single substance, but there are two main types: Low-density lipoprotein (LDL) cholesterol is the most harmful form.
