Vegetarian nutrition: past, present, future.

Early human food cultures were plant-based. Major religions such as Hinduism and Buddhism have recommended a vegetarian way of life since their conception. The recorded history of vegetarian nutrition started in the sixth century bc by followers of the Orphic mysteries. The Greek philosopher Pythagoras is considered the father of ethical vegetarianism. The Pythagorean way of life was followed by a number of important personalities and influenced vegetarian nutrition until the 19th century. In Europe, vegetarian nutrition more or less disappeared during the Middle Ages.

Dietary Reference Intakes for Calcium and Vitamin D

Calcium and vitamin D are two essential nutrients long known for their role in bone health. But since 2000, the public has heard conflicting messages about other benefits of these nutrients—especially vitamin D—and also about how much calcium and vitamin D they need to be healthy. To help clarify this issue, the United States and Canadian governments asked the IOM to assess the current data on health outcomes associated with calcium and vitamin D, as well as updating the nutrient reference values, known as Dietary Reference Intakes (DRIs).

Vegetarian diets across the lifecycle: impact on zinc intake and status.

Optimal zinc status is an important consideration when evaluating the nutritional adequacy of vegetarian diets. In the absence of animal tissue sources of zinc and with increased intake of inhibitors of zinc absorption, phytic acid in particular, the bioavailability of zinc is thought to be lower from vegetarian as compared to omnivorous diets. The aim of this chapter is to review the research that examines the effects of vegetarian compared to omnivorous diets on zinc intake and zinc status in the elderly, adults, children, pregnancy, and lactation.

Key elements of plant-based diets associated with reduced risk of metabolic syndrome.

Approximately 20 %-25 % of adults worldwide have metabolic syndrome. Vegetarian and vegan diets have demonstrated effectiveness in improving body weight, glycemic control, and cardiovascular risk factors, as compared with conventional therapeutic approaches, and are potentially useful in the prevention of metabolic syndrome.

A concept analysis: adherence and weight loss.

There are numerous factors that influence an individual's ability to adhere to a healthy behavior. The literature cites common events that must take place prior to maintaining an exercise plan, a medication regimen, and a healthy diet. The purpose of this paper is to examine the concept of adherence in relation to weight loss using Walker and Avant's (1995) framework for concept analysis.

The Health Advantage of a Vegan Diet: Exploring the Gut Microbiota Connection.

This review examines whether there is evidence that a strict vegan diet confers health advantages beyond that of a vegetarian diet or overall healthy eating. Few studies include vegan subjects as a distinct experimental group, yet when vegan diets are directly compared to vegetarian and omnivorous diets, a pattern of protective health benefits emerges.
