When it comes to food and nutrition, who is the expert? A dietitian or nutritionist?  Both make it their profession to advise on matters of food and how nutrition impacts health.  Both counsel people on what to eat in order to lead a healthy lifestyle or achieve a specific health-related goal.  Some use the terms "dietitian" and "nutritionist" as basically interchangeable.  However where you live determines what professional regulations are imposed and standards can vary extensively state to state or in the next country.  A registered dietitian in the US needs to have a bachelor's degree, complete an internship, take an exam and maintain ongoing education credits.  A nutritionist may have only taken a few classes in nutrition or may have a PhD in nutritional science or fall somewhere in between.  The best thing for anyone to do when looking for help with your diet is to ask each nutritional “expert” about their educational background, experience and be sure that he or she specializes in your needs.   

Holistic nutrition includes consciously eating healthy foods that promote vibrant physical and mental health, while supporting a strong immune system and preventing disease.  It looks at the total person, their responses to environment, their dietary intake including supplements and lifestyle. Holistic nutritionists' may interface with healthcare practitioners aiding in addressing chronic health challenges that respond to changes in food choices.  Holistic nutrition honors dietary needs based on ethnicity, religious and philosophical beliefs.

We could all potentially be healthier if we'd simply focus on prevention. Seeing a nutritionist is one way you can prevent serious health issues down the line. Suppose you are predisposed to high blood pressure, cardiovascular issues or diabetes. Nutritionists are trained to help you come up with a customized plan to overcome your health odds. A nutritionist is also effective at coaching you on how to support your body when you are sick.  A nutritionist will emphasize food as medicine; the healing impact of food as a contributing factor to overcome illness.
