1 (tie): DASH diet

For the eighth year in a row,the DASH diet was named the best (though this year the top slot was a tie). DASH stands for dietary approaches to stop hypertension. Otherwise known as abnormally high blood pressure, hypertension is a common condition in the US.

The diet involves lowering your sodium intake to no more than 2,300 milligrams a day and eating vegetables, fruits, and whole grains. (For reference, a single slice of pizza contains about 640 milligrams of sodium, roughly a quarter of that sodium limit.)

"The DASH diet is really a safe plan for everyone," Angela Haupt, assistant managing editor of health at US News & World Report, told Business Insider in 2016. "There's nothing exciting about it, and that's what makes it a good plan. It's not some fad diet making outlandish claims that you can't rely on."
