Oxidized cholesterol is the most dangerous killer of cardiovascular - cardiovascular, cholesterol - the pharmaceutical industries
Please carefully control your Cholesterol Intake! In particular, those not fascinated by oxidation of cholesterol-rich foods such as fried chicken, roast beef, trans fatty acids. The study is the first Chinese scientists found that the oxidation of cholesterol may be the most serious threat to cardiovascular health one of its more than without the oxidation of cholesterol lead to atherosclerosis, increased Heart disease And stroke risk.
Chinese University of Hong Kong research team led by Professor Chen Zhenyu, in a recent American Chemical Society 238 th National Conference on the published results of this study. This is the oxidation of cholesterol compared to non-oxidized cholesterol raise blood cholesterol levels, one of the first study. "So, we not only pay attention to their total intake of cholesterol and cholesterol intake should be concerned about the form?? Oxidation or non-oxidized." Zhen-Yu Chen says an interview.
Cholesterol detrimental hydroxyl
Oxidation of cholesterol in food, called hydroxyl cholesterol. Between fat oxidation and oxygen, will produce hydroxyl cholesterol. For example, foods containing fat is heated, such as fried chicken, grilled hamburgers or steak, oxidation reaction occurs. Others hydroxy cholesterol, is Food Manufacturers specifically to oxidation to produce the form of oil, such as trans-fatty acids and partially hydrogenated vegetable oil, to improve food texture, taste and stability.
Hydroxyl cholesterol to the public, as if "the most familiar stranger." People know that if a medical report in total cholesterol and LDL cholesterol (LDL) concentration high, which means their health turn on the lights?? Accumulation of cholesterol in the blood vessels so that blood vessels within the narrow, easily blocked. For those with high levels of hydroxyl-cholesterol food, people are not completely new, or even like dealing with them. But people had not realized that, in the food processing oxidation of cholesterol, than the original ingredients of not more dangerous oxidation of cholesterol.
Hamster experiments confirmed that the risk of
Researchers chose hamster as a model animal experiments, because the hamster blood cholesterol distribution and people are very close. The researchers designed two groups of hamsters of different recipes, diet is the hydroxyl group of cholesterol, another group of non-oxidized cholesterol for food. The results, feeding hamsters hydroxyl cholesterol, blood cholesterol levels rose more significantly, the inner walls of arteries have more cholesterol deposition, and there is an even greater deposition point (ie, atherosclerotic plaque) in the tendency, which increases heart disease and stroke risk.
In addition, the hydroxyl of cholesterol on the artery there is an "evil": it enables the arterial elasticity variation, weakened artery in the capacity and transport more blood, which help to dredge diastolic arterial blood vessels, reduce the the risk of heart attack or stroke. Eat more fruits and vegetables and effective resistance
Order to avoid excessive intake of cholesterol hydroxyl, Zhen-Yu Chen pointed out, fried food, barbecues, dried squid, etc., are all eating better. The researchers also suggested that eating a diet rich in antioxidants may prevent the formation of hydroxyl oxidation of cholesterol, may help reduce cholesterol in the body of the hydroxyl concentration. Source of antioxidants, including fresh fruits, vegetables, beans, etc..
