[Vegetarian diets of breastfeeding women in the light of dietary recommendations].

The literature review concerning selected nutritional and health aspects of applying different vegetarian diets by breastfeeding women was presented. The only two types of vegetarian diets: lactoovo- and semi-vegetarian, when properly composed, seem to be relatively safe for mother and her child. The most threatening vegetarian diets for lactating women are those including exclusively products of plant origin (so called restricted diets: vegan or macrobiotic).

Nutrient adequacy of a very low-fat vegan diet.

This study assessed the nutrient adequacy of a very low-fat vegan diet. Thirty-nine men (mean age=65 years) with early stage prostate cancer who chose the "watchful waiting" approach to disease management, were instructed by a registered dietitian and a chef on following a very low-fat (10%) vegan diet with the addition of a fortified soy protein powdered beverage. Three-day food diaries, excluding vitamin and mineral supplements, were analyzed and nutrient values were compared against Dietary Reference Intakes (DRI). Mean dietary intake met the recommended DRIs.

Position of the American Dietetic Association: vegetarian diets.

It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes. A vegetarian diet is defined as one that does not include meat (including fowl) or seafood, or products containing those foods.

[Effect of vitamin D supplementation on serum 25-hydroxyvitamin D and bone turnover markers concentrations in vegetarian children].

PURPOSE:Vitamin D plays a key role in bone mineralization by regulating calcium and phosphate metabolism. Deficiency of this vitamin may lead to disturbances in bone metabolism as well as to osteopenia and osteoporosis. AIM:1. Assessment of daily intake of calcium and vitamin D in children on vegetarian diet. 2. Measurement of serum 25-hydroxyvitamin D and biochemical bone turnover markers levels in vegetarian children supplemented with calcium and vitamin D, before and after the intervention.

The effect of vegetarian diet on selected essential nutrients in children.

NTRODUCTION:Vegetarian diets are considered to promote health and reduce the risk of some chronic diseases. It is also known that restriction or exclusion of animal foods may result in low intake of essential nutrients. The aim of the presented study was to assess the intake and serum status of vitamin B12, folate, vitamins A, E and D, as well as concentrations of homocysteine, total antioxidant status and iron balance in Polish vegetarian children.
