The American Dietetic Association and Dietitians of Canada have both released statements affirming that vegetarian and vegan diets are healthy at all stages of life, including infancy, adolescence, adulthood, pregnancy, and old age.
We encourage you as health care professionals, to support your patients’ choice to adopt a vegetarian or vegan diet.
In fact, given that diet is strongly related to heart disease, cancer, and diabetes (see journal articles linked below), we hope you would encourage your patients to move towards a plant-based diet. It is one of the most effective things patients can do to improve their overall health, and our resources show how easy it is.
If you have any questions or concerns about the legitimacy of vegetarian and vegan diets, please consider the information contained in the references listed below.
A great book, written by registered dietitians providing an overview of nutrient requirements for people on a vegan diet is Vegan for Life by Jack Norris and Ginny Messina. This book can be your one-stop reference guide to keep on hand to answer questions for your patients such as, should they take a B12 supplement? What nutrients do they need to look out for? What if they are a teenager, or over 50?
