Specifics relating to the development of heart disease and disease mechanisms
OBJECTIVE:Apolipoprotein(a) [or apo(a)] isoform size, which is strongly genetically determined, showed significant association with the cardiovascular risk. Subjects on a fish diet have lower lipoprotein(a) levels, larger apo(a) isoform sizes and lower leptin levels than their vegetarian diet counterparts. We hypothesized that leptin may contribute to a potential association between the type of diet and the size of apo(a) isoforms.
Oxidative stress is a natural physiological process that describes an imbalance between free radical production and the ability of the antioxidant defence system of the body to neutralize free radicals. Free radicals can be beneficial as they may promote wound healing and contribute to a healthy immune response. However, free radicals can have a detrimental impact when they interfere with the regulation of apoptosis and thus play a role in the promotion of some cancers and conditions such as cardiovascular disease.
The vegetarian diet may play a preventive role in the development of chronic diseases such as coronary heart and cardiovascular disease. However increase of homocysteine (Hcy) concentration in peoples avoiding animal products may contribute to an increased atherosclerotic risk in these subjects. Recent evidence has suggested that role of hyperhomocysteinemia in atherogenesis is associated with process of autooxidation, which can promote the production of hydroxyl radicals, resulting in oxidative modification of low density lipoprotein and endothelium injury.
OBJECTIVE:Many studies have shown that vegetarian diet has beneficial effects on the prevention of cardiovascular diseases. However, the effect of vegetarian diet on carotid intima-media thickness (IMT), as well as the association between IMT and duration of vegetarian diet, are still unclear. The present study aims to investigate the influence of duration of vegetarian diet on cardiovascular risk factors, and more importantly on IMT among Chinese vegetarians.
BACKGROUND AND AIMS:Vegan diet excludes all foodstuffs of animal origin and leads to cholesterol lowering and possibly reduction of cardiovascular disease risk. The aim was to investigate whether vegan diet improves the metabolic pathway of triglyceride-rich lipoproteins, consisting in lipoprotein lipolysis and removal from circulation of the resulting remnants and to verify whether the diet alters HDL metabolism by changing lipid transfers to this lipoprotein.
Clinical, hemodynamic and metabolic parameters were investigated for 42 patients with coronary heart disease, after myocardial infarct, recieved selective beta-adrenoblockers. Patients were divided in two groups. The first group (24 patients) were given methoprolol (50 mg/daily) and antiatherogenic lacto vegetarian diet, the second (18 patients)--methoprolol (50 mg/daily) and standard mixed antiatherogenic diet. After the treatment, positive changes clinical and gemodynamic parameters were observed in both groups of patients.
OBJECTIVE:This study aims to ascertain the relationships between mineral consumption, hair mineral content, and blood pressure. METHODS:The study involved 26 postmenopausal women from enclosed religious communities, 14 were semi-vegetarians and 12 were omnivores. Mineral dietary assessment was performed using a 14-d precise weight method and Food tables. Hair mineral levels were measured by means Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES).
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.

Pursuing professional training or graduate work is a challenging path - and it can be even more challenging if you're interested in pursuing something as unusual as plant-based nutrition!
