This topic interests me greatly, since my husband has a heart condition. Each year, Dr. Michael Greger does a search of the latest empirical research on nutrition and presents these facts in a series of videos on his website: nutritionfacts.org. His qualifications as an expert on nutrition are unsurpassed. He is a widely respected authority who bases his findings on valid, reliable science rather than bruhaha. In other words, he’s not in it to make money.
