The scientist finds : It is a cardiovascular most dangerous killer to oxidize cholesterol
Please control your taking in amount of cholesterol carefully! Don't especially be fascinated by those and contain rich amount of food which oxidize cholesterol such as fried chicken, grilled lamb chops, trans-fatty acid. The first discovery of research of the scientist of our country, cholesterol oxidized may be threatened by the most serious cardiovascular vessel health, it is apter to cause atherosclerosis than cholesterol that has not been oxidized, the risk that increase heart disease and apoplexy breaks out.
The scientific research group which Professor Chen ZhenYu of Chinese University of Hong Kong led, will announce this result of study at the national meeting on the 238th in chemistry of U.S.A. not long ago. This to oxidize cholesterol to oxidize cholesterol, raise the intersection of blood cholesterol and first batch of research of competence one of while being non-. " So, we should not only pay close attention to one's own total intaking amount of cholesterol, but also cholesterol form paying close attention to being taken in - -The ones that oxidize are not oxidized . " Chen ZhenYu says in this way while interviewing by this newspaper.
The cholesterol harmfulness of hydroxy is great
Cholesterol oxidized in the food, it is hydroxy cholesterol. Oxidizing and reacting between fat and oxygen, will produce hydroxy cholesterol. For example, the food which contains the fat is heated, such as the fried chicken, roast Hamburg or beefsteak, oxidizing and reacting will happen . Also there is hydroxy cholesterol, it was food manufacturers that make in the form of oxidizing the oil specially, if trans-fatty acid and hydrogenate the vegetable oil partly, in order to improve the texture, taste and stability of the food.
Hydroxy cholesterol,as to the public,like " L The most familiar stranger " . People know, if cholesterol (LDL) of lipoprotein of total cholesterol and low density in the physical examination report The density is simply high, mean one's own health lights up the alert light - -Cholesterol piled up in the blood vessel will make the blood vessel become narrow, apt to stop up. Containing food of a high level of hydroxy cholesterol as to those, people are not strange either, even like having dealings with it . But people have not realized before this, cholesterol oxidized in food processing, more dangerous than the primitive not oxidizing cholesterol while eating the material.
Hamster's experiment verifies the risk
Researchers choose the hamster how to carry on experimentally for the model animal, because cholesterol in hamster's blood is distributed and very close with people. Researchers are that two groups of hamsters have designed different recipes, one groups of diet is hydroxy cholesterol, another group is for not oxidizing cholesterol as the food. As a result, feed the hamster of hydroxy cholesterol, blood cholesterol density rises more prominently, there are more cholesterol that are deposited on the inboard wall of artery, and deposit some (namely atherosclerosis spot piece) more greatly Inclination,these increases heart disease and it is apoplexy risk.
In addition, there is one hydroxy cholesterol to artery " L The vicious behaviour " : It makes elasticity of the artery become bad, has weakened the ability of relaxation and transportation more blood of the artery, and this kind of relaxation contributes to dredging the artery blood vessel, lowering the risk of heart disease or apoplexy.
Eat more vegetables and fruits to resist effectively
In order to avoid taking in too much hydroxy cholesterol, Chen ZhenYu points out, fried food, meat-roasting, squid silk,etc., better to eat less . Researchers propose, eat the diet enriched with antioxidant and may stop forming the oxidizing and reacting of hydroxy cholesterol at the same time, may contribute to reducing the cholesterol density of hydroxy in the human body. The source against oxidant includes fresh fruit, vegetables, beans,etc.. (Dong ChunLei )
