The [US] federal government just released a new set of dietary guidelines, and as always, they’re a work of both science and politics. They include controversial changes: for instance, sugar now has a limit, and cholesterol does not. Here’s your guide to what’s new, what isn’t, and where the experts disagree.
I know of not one person who actually gives any credance to what the fools at the USDA say. Certainly not enough to measurably change their diets. But school lunches, WIC, and military meals are based on this. Dieticians base their advice off the guidelines. And media of all kinds is full of news about how people should be paying more attention to the new cholesterol and sugar guidelines.
Do we all go and look up exactly how many cups of vegetables we should be eating? No. But they do have a major effect on what the country eats. After all, if everybody ignored the guidelines, industry wouldn’t be so eager to influence them.
