What’s wrong with the American healthcare system? We had one of the world’s worst fatality rates with Covid and we trail most advanced countries in life expectancy. At the same time, we spend way more per capita on medical treatments. Matthew Rees, founder of Food and Health Facts, offers his incisive views on how to improve our nation’s health: we need more education, for the public and for health professionals; perverse incentives like subsidies for poor quality food need to be eliminated; and certain forms of food advertising to impressionable kids should be prohibited . Rees addresses the limitations of newly-popularized weight loss drugs. He discusses why health disparities are widening among Americans. And he offers lessons from the pandemic. Overall, his message is that we need to apply the same precision to prevention that we currently leverage toward development of pricey high-tech medical breakthroughs.
