What Are Disadvantages of Eating Vegetables?

While there are no disadvantages of eating vegetables, according to leading nutritionists, WebMD warns that sticking to an explicitly vegetarian diet can cause nutritional deficiencies. WebMD mentions vitamin B12, omega-3 fatty acids, iron, zinc, calcium and vitamin D as vital nutrients that are not present in a plant-based diet.

Dr. Lee Kurisko, the Chief Medical Officer of MediBid, says that vegetarian diets are usually high in carbohydrate content with little or no fats. This leads to a rise in blood sugar and, therefore, insulin, two significant causes of the body aging faster. Sticking to a vegetarian diet can also lead to problems for children including slow growth, reports The Independent.
