You’ve heard about adding more fruits and vegetables, along with fish and whole grains to your diet; sometimes it’s not exactly clear why. This chart spells in all out, connecting each item with its benefits. Whether such definitive connections can be drawn between eating specific foods and a corresponding health benefit is questionable from the point of view of hard science. For example, eating more avocados would not be a sufficient method of controlling your blood pressure. And I would not count upon eating grapefruit as a total solution to prostate cancer. A good diet is only one dimension of a comprehensive approach to health. Do include more of these foods in your diet; don’t assume that diet alone can prevent disease and guarantee immortality. Good things to eat and why.
