A well-planned vegetarian diet has been stated to be adequate during pregnancy. The aim of the present study was to compare serum vitamin B-12 and homocysteine concentrations in pregnant women (n = 109) consuming vegetarian and Western diets and to evaluate the adequacy of current dietary reference intakes of vitamin B-12 for these women. Pregnant women(More)
Anion exchange chromatography by High Performance Liquid Chromatography (HPLC) and the refractometric detection of the separated anions proved to be a rapid and sensitive method for the simultaneous determination of sulphate, nitrate, nitrite, chloride and phosphate in plants. Anion content was quantified using sodium selenate as internal standard. Only 20(More)
BACKGROUND Because reference values for vitamin B(12) concentrations and vitamin B(12)-binding capacities for pregnant women have not been established, the reference values for nonpregnant women are often applied to assess vitamin B(12) status. The aim of the present study was to describe ranges of biochemical indices of vitamin B(12) status, including red(More)
High consumption of vegetables and fruits is associated with reduced risk for cardiovascular disease. However, little information is available about diets based predominantly on consumption of fruits and their health consequences. We investigated the effects of an extremely high dietary intake of raw vegetables and fruits (70-100% raw food) on serum lipids(More)
OBJECTIVE To examine the relationship between the strictness of long-term raw food diets and body weight loss, underweight and amenorrhea. METHODS In a cross-sectional study 216 men and 297 women consuming long-term raw food diets (3.7 years; SE 0.25) of different intensities completed a specially developed questionnaire. Participants were divided into 5(More)
The treatment of early-stage tumours decreases the overall mortality of colorectal tumour patients. In this retrospective study we determined the sensitivity and the specificity of the faecal occult blood test (FOBT) and the molecular diagnosis (MD). We analysed 57 stool samples from patients with colorectal carcinomas for the presence of occult blood using(More)
Dietary carotenoids are associated with a reduced risk of chronic diseases. Raw food diets are predominantly plant-based diets that are practised with the intention of preventing chronic diseases by virtue of their high content of beneficial nutritive substances such as carotenoids. However, the benefit of a long-term adherence to these diets is(More)
OBJECTIVE To study in humans the relationship between a diet consistent with most of the current recommendations for the prevention of nutrition-related diseases (Wholesome Nutrition) and the blood lipid profile (total cholesterol, LDL-, HDL-cholesterol, LDL/HDL-ratio, triglycerides). DESIGN Cross-sectional study with two diet groups. SETTING Former(More)
The reductionist approach has traditionally been and continues today as the dominant approach in nutrition research. This means that parts of diet rather than the whole, or single food components rather than food habits, are studied. Even though much progress has been made with this approach, the relationship between diet and health is not yet fully(More)
OBJECTIVE To specify the principles, definition and dimensions of the new nutrition science. PURPOSE To identify nutrition, with its application in food and nutrition policy, as a science with great width and breadth of vision and scope, in order that it can fully contribute to the preservation, maintenance, development and sustenance of life on Earth.
