The Vegetarian Advantage: Its Potential for the Health of Our Planet, Our Livestock, and Our Neighbors!

Although vegetarianism has existed for thousands of years, the motivation originally came from philosophical and religious practices and traditions. Beginning about 200 years ago (particularly in the U.K., Germany and soon after the USA) there were prominent advocates for the positive effect of vegetarian diets on physical, and possibly mental health [1].

Worldwide incidence of hip fracture in elderly women: relation to consumption of animal and vegetable foods.

Hip fracture, a major health problem in elderly persons, varies in incidence among the populations of different countries and is directly related to animal protein intake, a finding that suggests that bone integrity is compromised by endogenous acid production consequent to the metabolism of animal proteins. If that is so, vegetable foods might provide a countervailing effect, because they are a rich source of base (bicarbonate) in the form of metabolizable organic anions, which can neutralize protein-derived acid and supply substrate (carbonate) for bone formation.

Vegetarian diets and public health: biomarker and redox connections.

Vegetarian diets are rich in antioxidant phytochemicals. However, they may not act as antioxidants in vivo, and yet still have important signaling and regulatory functions. Some may act as pro-oxidants, modulating cellular redox tone and oxidizing redox sensitive sites. In this review, evidence for health benefits of vegetarian diets is presented from different perspectives: epidemiological, biomarker, evolutionary, and public health, as well as antioxidant.
