Vitamins and cardiovascular disease

In their daily work, some patients can often be heard to say: "age, and blood vessels are hardened." Yes ah, the increase with age, arterial flexibility will decrease. This is mainly a few reasons: 1. Senile degenerative changes. 2. Hypertension to arterial fibrosis. 3. Artery atherosclerosis. Which atherosclerosis is the most common cause. Therefore, we say that atherosclerosis is a healthy cardiovascular system, the largest killer. From medical research, the formation of atherosclerosis are many reasons, simply put, is a variety of reasons so that damaged arterial endothelial cells, vascular wall permeability, resulting in excessive lipid composition In some parts of the arterial wall deposition, the formation of atherosclerotic plaque or stripes, and ultimately the affected artery compliance decreased flexibility and smaller lumen and thus lead to coronary heart disease, stroke and other ischemic disease. These diseases in the elderly is the main cause of death. Generally occurs in men over the age of 50 and post-menopausal women, such patients may also be accompanied by high blood pressure, abnormal lipid metabolism and diabetes, in turn, these diseases will increase the atherosclerotic process.

Anti-lipid-oxidant vitamin E, vitamin C help prevent atherosclerotic disease. They are one of the basic nutrients the body is to maintain essential life processes. Can usually be obtained through the daily diet, but in some cases, the need to add.

The current academic atherosclerosis accepted view is that: Atherosclerosis is a chronic inflammatory disease, is a gene-related diseases, and lipid oxidation (LDL) in atherosclerosis formation and the development process plays a key role. Smoking, exercise, diet, drugs, blood pressure induced by factors such as will produce a large number of oxygen free radicals and promote lipid oxidation, accelerate the atherosclerotic process. Therefore, to prevent atherosclerosis before the natural process to inhibit lipid oxidation. Vitamin E, C has a strong anti-lipid oxidation that can play in the early prevention of atherosclerosis stripe formation, to prevent the involvement of arterial wall thickening and hardening of the role. In the normal blood circulation contains antioxidants such as vitamin E, vitamin C, β-carotene molecule, superoxide dismutase, flavonoids, glutathione, hydrogen peroxide peroxidase enzyme enzymes natural antioxidants oxide, to a certain extent can play a protective effect of low-density lipoprotein. However, any unusual increase in the concentration of low density lipoprotein, and endothelial damage, such as the existence of circumstances, will be low-density lipoprotein into the arterial subendothelial infiltration, making the protective effect of disruption. If the patients at this time there was smoking, improper medication, hypertension and diabetes-induced factors, that would promote low-density lipoprotein oxidation, promotion of platelet adhesion, aggregation, thrombosis, promote vasoconstriction, vascular endothelial cell injury, increased arterial atherosclerosis in inflammatory response, thereby speeding up the atherosclerotic plaque formation. And vitamin E, vitamin C may be through their powerful antioxidant, can reverse the process, thus prevention and treatment of atherosclerosis.

Atherosclerosis in the heart of a concrete manifestation of that people should be well-known coronary heart disease. Evidence-based medicine clinical study results showed that the plasma lipid content of vitamin E and coronary heart disease mortality have a strong inverse relationship. Vitamin E content is low will increase the risk of cardiovascular events, myocardial infarction survival in young patients compared with healthy control group, the former plasma lipids of vitamin E content is low. It is worth noting that, for a daily dose of vitamin E in more than 400IU of clinical trial results are positive, while the daily dose of 400IU following on atherosclerosis had no significant effect of vitamin E in order to further confirm the anti-atherosclerosis and the relationship between dose, different doses (200IU-2000IU) of Vitamin E, two large sample of evidence-based medical research is in progress, and we look forward to the results.

Studies have found that vitamin E intake of more women, in the carotid artery bifurcation Department deposition of fatty plaques in the lowest level. In postmenopausal women, the lowest level of vitamin E intake of the people, the possibility of emergence of artery plaque increased by almost 3-fold, regardless of their age, smoking habits, blood pressure, body mass index and other heart disease risk factors.

In addition, the vitamin E on the one hand, ischemic disease can reduce the risk of the disease, on the other hand will increase bleeding, such as the risk of cerebral hemorrhage. Thus, excessive intake of vitamin E can not be taking the former must be agreed with the consent of a doctor.

Vitamin C is also an antioxidant that promotes the mesenchymal cells and collagen formation, the protection of the integrity of blood vessels, but also have a certain role in the prevention of atherosclerosis. Studies have found that heart attack patients, the blood vitamin C content decreased, but after rehabilitation in patients with vitamin C levels returned to normal. Reasons yet to be studied further.

High vitamin E content of food oils such as wheat germ oil, corn oil, peanut oil, sesame oil, wheat germ, spinach, eggs, cabbage, the beans, and other coarse grains and fish.

High vitamin C content in food such as fresh vegetables, green vegetables, leeks, eggplant, onions, tomatoes, pepper, cabbage and potatoes, spinach, fresh fruit such as oranges, grapefruit, lemons, dates, hawthorn, kiwi, etc..

Cell Biology University of California, Professor Parker said: "The most important antioxidants is vitamin E. C", in recent years, in Europe and the U.S. people call it anti-aging agent, because they can not only protect but also the protection of human organs skin damage from oxygen free radicals and aging, to the effect of beauty.

Need to remind that in recent years, the prevalence of dieting to lose weight, weight loss caused by unscientific nutrition structure is not balanced, a variety of vitamins and nutrients is too low, it is difficult to protect the human body daily supply of essential nutrients, which to some extent may explain why some people fat is reduced, Keren is also old. This diet is not advisable. Special recommendation of a friend would like to lose weight, preferably in a balanced diet, based on the combination of active physical exercise to achieve weight loss purposes, so as not to strike a balance.
