The Whole30 diet is a way to hit the reset button, to give your digestive system a break, and help you forge a new relationship with food. With this elimination-style diet, you’re told to cut out items that are known to upset some tummies or are generally unhealthy—all processed or packaged food, natural and artificial sugars, alcohol, grains, beans, legumes, soy, and dairy are off the menu for 30 days straight. Meat, seafood, eggs, vegetables, nuts, oils, and fruits are allowed. The goal is to rewire your brain to crave whole foods and to weed out items that aren’t settling well with you. After 30 days, you can slowly add food groups such as beans and whole grains back into your diet as a method of testing for food sensitivities.
