An excellent video that explains the state of nutrition in the U.S. Although many factors contribute to the causes of obesity and diabetes, food policies in the past few decades may have played a predominant role. However, the debate continues as to whether saturated fat and cholesterol are villains or not. Did our obesity epidemic begin when the guidelines recommended a low fat diet and 6 -11 servings of carbohydrates a day? Did Ancel Keys and his Seven Countries Study get it wrong way back in the 1970’s that changed the U.S. food culture?
This dilemma points out some basic problems with nutrition research which has been under fire for its reliance on weak evidence from observational studies. It will be interesting to see what happens to these Guidelines the next time they are due- sometime in 2020. Stay tuned.
