Be vigilant against the “killer” hidden in blood vessels


           Atherosclerotic plaque is invisible and impalpable without modern medical equipment and is the “No. 1 killer” hidden in blood vessels. Why do people say atherosclerotic plaque is the “No. 1 killer”? This is because plaque seriously harms the health of blood vessels. Although the formation of plaque is a very slow process, and the patients tend to have no obvious symptoms, lesions caused by plaque, such as myocardial infarction, often happen suddenly and sometimes even kill people within several minutes, making people be caught off guard.

      Plaque formation and lesion hazard

      Atherosclerotic plaque formation is a long process, with an incubation period of about 10-20 years, and the symptoms do not appear until middle age or middle and old age. Our blood vessel endothelium is damaged by hypertension, hyperlipidemia, hyperglycemia, smoking, etc., which causes deformation, necrosis and shedding of endothelial cells, leaving the endothelium underlying tissue exposed. When the endothelium is damaged, the blood vessel “garbage” such as triglyceride, cholesterol, etc. of increased levels enters the vessel wall through the damaged endothelium and is deposited under the endothelium to thicken and harden the endothelium. At the same time, the platelets that stop bleeding rapidly adhere to and gather at the damaged part and gradually form atherosclerotic plaque. What is more, it may cause sudden death. For example, when one rages, does strenuous exercises, hits the bottle, or is in a cold environment, which causes increased blood pressure, blood flow impact or vasospasm, the diolame will be broken, the lipid, etc. in the plaque will gush and form thrombus. If the cardiac vessels are clogged, acute myocardial infarction may be caused, leading to sudden death.

       Coronary atherosclerotic heart disease is the most common type of organ lesion caused by atherosclerosis as well as a common disease hazardous to human health. It usually happens after 40 years old. Myocardial infarction, the most serious manifestation of coronary heart disease, causes the death of cardiac cells due to clogged arteries which blocks the blood supply to the heart.

      In western developed countries, such as USA, etc., coronary heart disease is the No. 1 killer that causes death, with the attack rate of about 5%. One of 20 persons has coronary heart disease. In China, although the attack rate of coronary heart disease is not as high as in western countries, the rate has been rising significantly since 1990s. It is estimated that the death toll related to coronary heart disease in China currently exceeds 1 million.  

      The power of the “killer” can be reduced artificially

      Lesions caused by atherosclerosis cause severe harm to the body. Is there any method to prevent or reduce its harm? The answer is yes. Now let the dietician of SAMLY ETIT Nutrition and Health Research Center give you help:

     COMPOUND VITAMIN B (B1, B6, B12, and folic acid), VITAMIN C, VITAMIN E, etc. play an active role in preventing and treating atherosclerosis.


    1. Vitamin B1

     Vitamin B1 is the important ingredient of phosphopyridoxal which is the important substance that regulates glycometabolism. Therefore Vitamin B1 is the vitamin required to fully utilize sugar in the body as well as the essential vitamin that maintains the normal functions of the cardiovascular, nervous, digestive, and muscular systems. Vitamin B1 has a good blood fat reducing effect.

      Good Sources of Vitamin B1: Internal organs of animals, lean meat, whole grain, beans, and nuts.

      2. Vitamin B6 and folic acid

      Intervene experiments proved that high Vitamin B6 and folic acid intake reduces the attack rate of myocardial infarction and fatal coronary heart disease. Although they have individual effects respectively, they jointly participate in homocysteine metabolism through such effects, thus prevents cardiovascular disease. In the intervene experiments, folic acid was given at the level of less than 400ug/day and Vitamin B6, greater than 3mg/day, to minimize the risk of coronary heart disease.

      The good source of Vitamin B6 is meat, in which, chicken and fish contain the highest level of Vitamin B6, followed by liver, beans, and yolk. Fruits and vegetables also contain high level of Vitamin B6.

      Folic acid is an important Compound Vitamin B and is mainly from such foods as liver, kidney, egg, beans, yeast, green vegetables, fruits, and nuts (walnut and peanut).

      3. Vitamin B12

      Vitamin B12 plays a part in suppressing peroxidation and lowering blood fat levels in the body.

      The major food source of Vitamin B12 is meat, including animal liver, fish, birds, mussel, and eggs.


      Vitamin C participates in the hydroxylation reaction of many biologically active compounds in the body, participates in cholesterol metabolism to convert 80% of the cholesterol to cholic acid which is eliminated from the body, thus lowers cholesterol levels in the blood, and removes the cholesterol deposited on the arterial wall to increase the healthful component HDL-c (high-density cholesterol) in the blood, which is very important for preventing atherosclerosis. Vitamin C participates in the synthesis of collagen in the body to increase the flexibility of blood vessels, thus prevents bleeding from vessels. At the same time, Vitamin C is an antioxidant and can catch free radicals to prevent lipid peroxidation of unsaturated fatty acids.

      The major sources of Vitamin C are fresh vegetables and fruits.

       VITAMIN E

       A lot of clinical applications indicate that Vitamin E can prevent and treat cardiovascular disease. Vitamin E is a strong antioxidant and can prevent and reduce the harm caused by lipid peroxidation to protect cell membrane, enhance the flexibility of blood vessels, and improve minicirculation, which is favorable to preventing the formation and development of atherosclerosis; and can suppress the agglutination of platelets on the vessel wall, thus reduces the damage of endothelial cells of blood vessels and reduces the risk caused by thromboembolism. In addition, Vitamin E promotes arachidonic acid’s conversion to prostaglandin which dilates blood vessels and suppresses platelet agglutination. To prevent atherosclerosis, intake of unsaturated fatty acids should be increased. But unsaturated fatty acids cause peroxidization easily, therefore Vitamin E intake should be increased properly. In general, 1g unsaturated fatty acids require 0.6mg Vitamin E.

       The major sources of Vitamin E are vegetable oil, wheat germ, xylocarp, seeds, beans, and other grains.
