Although fruit provides a source of carbohydrates, they have very little protein, and because protein cannot be stored in the body as fat and carbohydrates can, fruitarians need to be careful that they consume enough protein each day. When the body does not absorb enough protein, it leads to a deficiency of amino acids, which are essential to creating body proteins which support the growth and maintenance of body tissues. Consuming high amounts of fruit also poses a risk to those who are diabetic or pre-diabetic, due to the negative effect that the large amounts of sugar in fruits has on blood sugar levels. These high levels of sugar mean that fruitarians are at a higher risk for tooth decay. Another concern that fruitarianism presents is that because fruit is easily digested, the body burns through meals quickly, and is hungry again soon after eating. A side effect of the digestibility is that the body will defecate more frequently. Additionally, the Health Promotion Program at Columbia reports that food restrictions in general may lead to hunger, cravings, food obsessions, social disruptions, and social isolation.Alice!, Health Promotion Program at Columbia University, Health Services at Columbia, August 23, 2002. "Go Ask Alice!: Fruitarian teens". Accessed May 20, 2008. The severe dietary restrictions inherent in a fruitarian regime also carries the serious risk of triggering orthorexia nervosa.
