Influence of vegetarian and mixed nutrition on selected haematological and biochemical parameters in children.

To evaluate the health and nutritional status of children with two different nutritional habits, the authors examined 26 vegetarians (lacto- and lacto-ovo; an average period of vegetarianism 2.8 years) and 32 individuals on mixed diet (omnivores) in the age range 11-14 years. Vegetarian children had significantly lower erythrocyte number as well as reduced levels of haemoglobin and iron compared to omnivores. The average level of iron did not reach the lower limit of the physiological range and hyposiderinemia was found in 58% of vegetarians vs 9% of omnivores.

Growth, development, and physical fitness of Flemish vegetarian children, adolescents, and young adults.

This study was designed to assess average daily dietary intakes of energy in 82 vegetarian children (group A: 6- 9-y-old girls and 6-11-y-old boys), adolescents (group B: 10- 15-y-old girls and 12-17-y-old boys), and young adults (group C: 16-30-y-old females and 18-30-y-old males) and included determination of height and weight; triceps, suprailiac, and calf skinfold thicknesses; puberty ratings; and physical fitness. Dietary energy intake was lower than recommended values in all 3 groups.

Vegetarian food guide pyramid: a conceptual framework.

The purpose of this article and the accompanying vegetarian food guide pyramid graphic is to provide the conceptual framework for the development of a new and unique food guide. Food guides for vegetarians have tended to be adaptations of guides developed for the general nonvegetarian population instead of being designed to emphasize the healthy components of vegetarian dietary patterns.

The contribution of vegetarian diets to health and disease: a paradigm shift?

Advances in nutrition research during the past few decades have changed scientists' understanding of the contribution of vegetarian diets to human health and disease. Diets largely based on plant foods, such as well-balanced vegetarian diets, could best prevent nutrient deficiencies as well as diet-related chronic diseases. However, restrictive or unbalanced vegetarian diets may lead to nutritional deficiencies, particularly in situations of high metabolic demand.

Spicing up a vegetarian diet: chemopreventive effects of phytochemicals.

Thousands of chemical structures have been identified in plant foods. Many are found in spices. Typically, spices are the dried aromatic parts of plants-generally the seeds, berries, roots, pods, and sometimes leaves-that mainly, but not invariably, grow in hot countries. Given the wide range of botanical species and plant parts from which spices are derived, they can contribute significant variety and complexity to the human diet.

[Lipids and vitamin A and E status in vegetarian children].

BACKGROUND:The vegetarian diet may play a preventive role in the development of chronic diseases such as coronary heart disease, cancer and diabetes. In the literature only a few papers concerning benefits to health from vegetarian diet have been reported in children. AIM:The aim of this study was to investigate serum concentration of vitamin A (retinol) and E (alpha-tocopherol) in children on vegetarian and omnivorous diet. Material and methods. Vitamins A and E were measured by high-pressure liquid chromatography (HPLC) in blood of 17 vegetarians and 16 nonvegetarian children.

Effects of a low-fat vegan diet and a Step II diet on macro- and micronutrient intakes in overweight postmenopausal women.

OBJECTIVE:This study investigated the nutrient intake of overweight postmenopausal women assigned to a low-fat vegan diet or a Step II diet. METHODS:Fifty-nine overweight (body mass index, 26 to 44 kg/m2) postmenopausal women were randomly assigned to a self-selected low-fat vegan or a National Cholesterol Education Program Step II diet in a 14-wk controlled trial on weight loss and metabolism. Nutrient intake, which was measured per 1000 kcal, was the main outcome measure. Statistical analyses included within-group and between-group t tests examining changes associated with each diet.
