At present, many people want to remove cholesterol from the diet, it seems that not doing so can not maintain normal blood cholesterol levels. Recently, Dr. Yu Kang of Peking Union Medical College Hospital told the author that in fact, this is neither realistic nor conducive to health.
Many clinical studies have made it clear that an increase in serum total cholesterol is an independent risk factor for coronary heart disease. The higher the cholesterol, the greater the risk of atherosclerosis and the earlier the time. Every 1% reduction in serum total cholesterol, the risk of coronary heart disease can be reduced by 2%%. If you are concerned about the possible harm to human body due to the increase of serum cholesterol, do not overlook the benefits of normal cholesterol levels on the human body. For example: it is an important component of human cells, is the premise of synthesis of many important hormones and vitamins, and is important for the brain, liver, etc. Organ components ... lack of cholesterol can lead to a series of health problems.
Only about 30% of cholesterol comes from diet, and 70% comes from in vivo synthesis. If the cholesterol in the diet is strictly limited, the in vivo synthesis will increase. Conversely, if the dietary intake of high cholesterol, the body synthesis will be reduced, in general, the two maintain dynamic balance. Perhaps this may explain to some extent why some people who eat vegetarian food for a long time and have low dietary cholesterol may also have elevated blood cholesterol. Since cholesterol is often coexisted with other nutrients in the diet, excessive restriction of cholesterol may simultaneously limit the reasonable intake of other beneficial nutrients, which is detrimental to health.
How low is the appropriate level of serum total cholesterol? This has long been a debate in the academic community. Some people think that low serum total cholesterol can cause cerebral hemorrhage and increase the incidence of cancer, especially for the elderly, which is more meaningful, but it still requires a lot of epidemiological evidence to confirm. In some patients with dysentery, serum cholesterol can be reduced to very low levels, which is actually a manifestation of severe malnutrition.
At present, the intake standard of dietary cholesterol in many countries is no more than 300 milligrams per day. For those with increased low-density lipoprotein cholesterol, the cholesterol intake is further limited to less than 200 milligrams per day. At the same time, the proportion of energy for saturated fatty acids should be less than 7% of the total energy. Foods that are rich in cholesterol and saturated fats include fatty meat, animal oil, palm oil, coconut oil, egg yolk, and animal organs. Regardless of whether healthy or coronary heart disease patients, should eat or not eat these foods, but this does not mean that you can not eat animal foods, on the contrary, the amount of intake of lean meat, fish, milk, eggs or egg whites, etc. It is necessary to maintain human health.
