> Sandwiches have grown less healthy in the past 40 years, Dr. Mozaffarian says. Culprits include highly processed grains in bread and the low-fat push that took off in the 1980s, which nutritionists now say led to the consumption of more deli meats marketed as low-fat. Low-fat wasn't just a "push". Medical experts effectively lobbied the government to introduce dietary mandates at very high levels (like nutrition percentages) and on low levels (school lunches). The end result was carbs, carbs, carbs, cheap carbs. The glycemic index is probably one of the most underrated aspects for diet. It boggles my mind that the doctor at the end recommended a PB&J. Sure - in a complete vacuum it has fewer calories. But you are going to end up way hungrier and crankier calorie-for-calorie.
