Food: it's good (or bad) for your health!
Nutrition and health are closely related: this is literally the title of the introduction's first section. OK. Thanks.
In fairness, this part is where the guidelines are at their best, since they acknowledge that even as lifespan has increased and nutrient deficiencies have largely become a thing of the past, chronic diseases related to nutrition -- think diabetes, obesity, and atherosclerosis -- have risen sharply. More than two-thirds of American adults are overweight or obese. Yes, nutrition and health are related! Closely, even!
People can't survive on nutrients alone
Uh, tell that to the makers of Soylent, USDA. Guess coding efficiently wasn't a factor in the guidelines, which is a Big Miss for the government. This is why there's no #innovation at the national level. Silicon Valley should be running the country.
