For four decades, the U.S. Dietary Guidelines warned Americans to limit dietary cholesterol to 300mg per day. This meant restricting eggs, shrimp, and other cholesterol-containing foods. Then, in 2015, the guidelines quietly removed cholesterol restrictions. No press conference. No apology. Just... silence. What changed? Not the science—research questioning the dietary cholesterol-heart disease link existed for decades. What changed was that they could no longer ignore it. But they're still not explaining how millions of people avoided healthy foods unnecessarily for 40 years.
