McDougall weighs in (pun intended) on The Patient Protection and Affordable Care Act: It’s the food! Until the spotlight shines on the cause of most chronic illnesses there will be no real solutions. Recommendations for a better diet, which are currently considered prudent, sensible, and reasonable—such as to eat chicken, fish, and low-fat dairy products—have not and never will in the future bring about worthwhile improvements in people’s health.

McDougall debates whether you should be taking a daily aspirin.

Fish oil does not improve cognitive function, according to new research. Researchers in England found that fish oil did not benefit the cognitive function of elderly adults after two years of daily supplementation. In a double-blind control trial, 867 people with a mean age of 75 years were assigned to either a fish supplement (200 mg EPA plus 500 mg DHA) or placebo (olive oil) group. Participants were given various tests for cognition including reaction time, spatial memory, and processing speed measurements. No significant differences were seen between groups.
