Joan Salge Blake, MS, RD, clinical associate professor of nutrition at Boston University, said there is nothing to worry about if a person considered going vegetarian, and with healthy urges of thinking the meatless life -  "Nothing dramatic is going to happen biochemically."

Joan Salge Blake stated,"We hypothesize that patients with taste impairment may have malabsorption of dietary zinc." There has been a recommendation for new vegetarian's need to make a special effort to eat enough vegetables.

Neal Barnard, MD, adjunct associate professor of medicine at the George Washington University School of Medicine in Washington, DC, founder and president of the Physicians Committee for Responsible Medicine (promoting a plant-based diet for disease prevention), have made a theoretical or laboratory study of vegetarian diets in terms of weight loss. In the Journal of the Academy of Nutrition and Dietetics, Neal Barnard published a person going for vegetables tends to lose a few pounds.

Liz Applegate, PhD, director of sports nutrition at the University of California, Davis said, "Your body has digestive enzymes that handle the proteins in both meat and plants, and that doesn't change when you stop eating meat." Liz Applegate said at first, going green a person may gain some healthy bacteria.

Researchers have confidence that the new carbs of a meatless life can help  increase or improve the population of healthy bacteria in the stomach.

Being a vegetarian can protect a person from heart disease as said by Emily Bailey, RD, director of nutrition coaching, sports nutrition, eating disorders, and weight management at NutriFormance in St. Louis, "Plant-based diets have been proven time and again to be anti-inflammatory."

The death from ischemic heart disease will happen 24% lower in vegetarians than in carnivores.

Studies recommends that vegetarians may need to supplement, but in a moderate or within a reasonable limit. Vegetarian people need the same amount of iron as carnivores as well as calcium and even vitamin B12, which is absolutely necessary for proper nerve function.
