The Complete Diet The complete diet includes adequate high-quality protein, healthy fats and oils and the right carbohydrates from fruits and vegetables, which bring along vitamins, minerals and antioxidants. Supplements play a role by reinforcing what is missing from the total diet, by providing increased amounts of nutrients with health benefits that would be impractical to obtain through foods, and by providing a healthy behavior that reinforces a healthy diet and an active life. Integrative nutrition is not about taking food apart to find the active ingredient, but rather it is about bringing together the many different nutrients that interact in our bodies to provide health benefits.
