Diet..

 

The Harvard diet is actually Harvard's Healthy Eating Plate, and it can be used as a guide for "creating healthy, balanced meals."

For the diet, you should prioritize vegetables and fruits for half of each meal and supplement the other half with whole grains and healthy proteins.
Here's a thorough breakdown of how to set your plate.

Use Olive, Canola, Soy, Corn, sunflower, Peanut (unless you're allergic)

What makes the eating plan unique is the disclaimer to stay active, which is almost as prominent as the breakdown of foods and drinks.
