DASH is listed first in the U.S. News rankings, but authoritative reviews have found that it’s been tested on only about 2,000 subjects (mostly middle-aged hypertensives) in studies lasting no longer than six months. Its effects can hardly be generalized to all Americans.
In those limited studies, the diet, which promotes fruits, vegetables and low-fat dairy, did lower some cardiovascular risk factors, such as blood pressure. But it usually worsened others, such as HDL cholesterol (the good kind) and triglycerides. And the one and only time it was tested against a higher-fat version of itself, the higher-fat version performed better.

Promoting the same dietary advice over and over again while expecting different results is indeed a kind of insanity, and worse, is doing nothing to combat rising disease and death rates.
