Surfing the Web nearly always involves running into a few ads, blogs, and articles about diet and health. Perhaps you also have relatives or friends who send you links about what you should (or shouldn’t) be eating to lose weight, lower your blood pressure, or dodge heart disease.

You might be skeptical enough to avoid clicking on suspicious links, like those once-popular ads promising “one weird trick to banish belly fat.” Yet sometimes the advice appears to be from a legitimate source — for instance, a purported world-class heart surgeon who’s written books about diet and nutrition. But what if the recommendations run counter to what you’ve mostly heard about a heart-healthy diet? It’s no wonder many people feel confused and frustrated about nutrition.
