Studies question fatty acids' heart benefits

Many health organizations, including the American Heart Association, recommend eating polyunsaturated fatty acids - particularly those called omega-3s and omega-6s - for heart health.  But new research once again casts doubt on whether these fatty acids have any effect on reducing your risk of heart disease.

A meta-analysis published Monday in the journal Annals of Internal Medicine did not find significant evidence to support eating a diet high in polyunsaturated fatty acids and low in saturated fats. It didn't seem to matter whether the fats came from dietary sources or supplements.

"Current evidence does not clearly support guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats," the study authors concluded.

And a second study, published in the journal JAMA Internal Medicine, found that supplementing a diet with long-chain omega-3 polyunsaturated fatty acids did not reduce study participants' heart disease risk.

Colon cancer rates down since 1980s

Colon cancer, which was once the most common cause of cancer death in America, has been on a steady decline for decades, according to a new study in CA: A Cancer Journal for Clinicians.

In 1985, there were an estimated 66.3 cases of colon cancer for every 100,000 adults in the United States. By 2010 that rate had fallen to 40.6 cases for every 100,000 adults. Deaths dropped during the same time period as well - from 28.5 to 15.5 deaths per 100,000 people.

"Incidence is declining primarily because of screening and finding polyps, which are precancerous lesions that can be removed," said Dr. Otis Brawley, chief medical officer for the American Cancer Society. "We find these precancerous lesions, remove them and 'voilà!' the patient doesn't get cancer."
