May Stabilize Blood Sugar Several studies indicate that vegetarian diets may help maintain healthy blood sugar levels. For instance, one review of six studies linked vegetarianism to improved blood sugar control in people with type 2 diabetes. Vegetarian diets may also prevent diabetes by stabilizing blood sugar levels in the long term. According to one study in 2,918 people, switching from a non-vegetarian to a vegetarian diet was associated with a 53% reduced risk of diabetes over an average of five years.
