Studies that relate to population-based data on heart disease prevalance and incidence
Fasting samples of 1329 apparently healthy vegetarian Gujarati population were tested for total cholesterol, triglycerides and three major fractions of lipoproteins, i.e. high density lipoproteins, low density lipoproteins and very low density lipoproteins. All the values showed marked increase with the age. Except for serum triglycerides, values differ in males and females in the age group of above 45 years.
BACKGROUND:Several epidemiological studies have implicated hypercholesterolemia and hypertriglyceridaemia as a dietary risk factor in the etiology of vascular disease. To date, there are virtually no blood lipid data available for Negroid Black African Seventh-Day Adventist vegetarians. This study was undertaken to gain a preliminary and better understanding of the relationships between BP, blood lipids, and diets in adults at the Seventh-Day Adventist Seminary of West Africa, Ilisan-Remo, Nigeria.
Dietary habits have been implicated in the occurrence of cardiovascular diseases. Elevated plasma fibrinogen levels and decreased fibrinolytic activity have been identified as major independent cardiovascular risk factors. In this study, we compared the blood pressure, plasma fibrinogen concentration, and fibrinolytic activity of 40 nonvegetarians (NON-VEGs) with 36 vegetarians (8 VEGs and 28 SEMI-VEGs). The latter group consisted of students and lecturers of the Adventist Seminary Institute of West Africa, Ilishan Remo.
Populations of vegetarians living in affluent countries appear to enjoy unusually good health, characterized by low rates of cancer, cardiovascular disease, and total mortality.
The Oxford Vegetarian Study is a prospective study of 6000 vegetarians and 5000 nonvegetarian control subjects recruited in the United Kingdom between 1980 and 1984. Cross-sectional analyses of study data showed that vegans had lower total- and LDL-cholesterol concentrations than did meat eaters; vegetarians and fish eaters had intermediate and similar values. Meat and cheese consumption were positively associated, and dietary fiber intake was inversely associated, with total-cholesterol concentration in both men and women.
BACKGROUND:Plasma homocysteine levels have been directly associated with cardiac disease risk. Current research raises concerns as to whether comprehensive lifestyle approaches including a plant-based diet may interact with other known modulators of homocysteine levels. METHODS:We report our observations of homocysteine levels in 40 self-selected subjects who participated in a vegan diet-based lifestyle program.
OBJECTIVE:To compare fasting total plasma homocysteine (tHcy) levels in vegans, lacto-ovovegetarians and control subjects, and to evaluate the relationships between tHcy levels and nutritional variables in vegetarians. METHODS:The study was conducted on 45 vegetarian subjects: 31 vegans (19 males, 12 females, mean age 45.8 +/- 15.8 years); 14 lacto-ovovegetarians (6 males, 8 females, mean age 48.5 +/- 14.5 years), and 29 control subjects (19 males, 10 females, mean age 43.4 +/- 16.7 years). tHcy was evaluated by high-performance liquid chromatography.
The articles included in this library are original, peer-reviewed research papers, also known as "primary sources". Peer-reviewed papers are those published in journals who use a committee of other scientists to carefully review the author's study methods, analysis, and conclusions, and to provide feedback for improvements before publication. The result are papers whose authors who are rigorously held accountable for their statements. Click here for a list of inclusion criteria.
