Medical practitioners including all doctors definitely have their place, but when it comes to learning about what to do to improve your nutrition, seek the help of a qualified nutritionist. Medical doctors do not have specific training to assist in this area. If you have a foot problem see a podiatrist. If you have a breathing problem see a pulmonologist. If you have a diet or weight problem, if you have a genetic predisposition toward a particular disease, if you need to learn more about how to properly feed yourself and your family, see a nutritionist. Your nutritionist can help you create the biggest defense zone between you and preventive disease, including any excess weight or obesity. Instead of trying figure nutrition out on your own, hire a diet and nutrition professional. Hire a licensed Academy of Nutrition and Dietetics (A.N.D.) nutritionist.
