“In nutrition, guidelines established in the 1970s advised Americans to severely restrict all dietary fat and to eat more carbohydrates. The original 1992 Food Guide Pyramid published by the U.S. Department of Agriculture (USDA) advised Americans to eat six to eleven servings every day from the bread, cereal, rice, and pasta group. The images used included pictures of such “healthy” foods as white bread, pasta, and crackers. The USDA also advised Americans to eat sparing amounts of foods such as avocados, salmon, nuts, and olive oil, due to misplaced fears about fat.”
