In children, lead exposure has been associated with stunted growth and causes permanent cognitive impairment. For the lead-wary, researchers recommend that consumers choose calcium supplements that are specifically labeled as having been tested for lead content. When it comes to keeping colon cancer at bay, olive oil plays just as important a role as fresh fruit and vegetables, a British study finds. According to Reuters, a team of researchers at London's Institute of Health Sciences compared cancer rates, diets and olive oil consumption in 28 countries, finding that diets rich in olive oil and low in meat were associated with a decreased risk. Researchers suspect olive oil protects against colon cancer by regulating the enzyme diamine oxidase, which may be linked to cell division in the bowel.
Colon cancer is the second most common cancer in the United States, after lung cancer.
