2016 edition of the Dietary Guidelines for Chinese Residents, high-cholesterol foods can be released to eat?

recently, a post about cholesterol in a circle of friends was frantically retweeted: "The latest version of the Dietary Guidelines for U.S. Residents removed the daily cholesterol intake limit of
300 mg
, and cholesterol, which has been wrong for years, has finally been 'whitewashed'!" A similar post declared, "The claim about cholesterol is the biggest medical deception ever," "No need to change cholesterol intake, cholesterol intake neither causes nor prevents heart disease" . . .
May

13
, the Chinese People's Dietary Guidelines
2016
, also did not mention cholesterol intake restrictions, and recommended eating eggs without throwing away egg yolks. So, in the future to eat meat, eat eggs really do not have to consider the problem of cholesterol?cholesterol is not a "bad thing cholesterol is widely found in animal foods, especially in brain and nerve tissue, and high in kidneys, spleen, skin, liver and bile. Doctors warn of the risk of arteriosclerosis and heart disease after testing for high levels of cholesterol in the bleeding, which many have equated with "bad things" harmful to the body for years. In fact, cholesterol is also an indispensable substance for the human body, the content can not be too high or too low.Huang Yufang, deputy director of nutrition at Guangzhou Medical University's affiliated oncology hospital, said cholesterol is an indispensable and important substance in animal tissue cells, which is involved in the formation of cell
membranes and nerve fibers
; Ultraviolet radiation in the transformation into vitamin
D3
; the formation of bile salt emulsified fat, promote fat digestion and absorption; help to repair and maintain integrity of the blood vessel wall, if the serum cholesterol content is low, the blood vessel wall will become fragile, increase the risk of bleeding;that is to say, if cholesterol is simply criminalized as a "bad thing", it is indeed wronged.Professor Zhu Huilian, vice chairman of the Senior Nutrition Branch of the Chinese Nutrition Society and a doctoral tutor in the Department of Nutrition at Zhongshan University, told reporters that our bodies can also synthesize the cholesterol they need, such as fatty acids, amino acids and sugars, which can be used by the body as raw materials for cholesterol synthesis, and when cholesterol is eaten more, the body's synthesis will be reduced. When you eat a lot of high-energy substances, the body synthesizes more cholesterol, which may be more than we eat ourselves, so we're not looking at cholesterol intake, we're looking at the calories and fat that the whole food brings.the removal of dietary cholesterol limits is not due to cholesterol-soundingthe latest U.S. Dietary Guidelines remove the limit of no more than
300,
milligrams of dietary cholesterol intake per day, causing widespread concern., deputy director of the National People's Congress, said that in fact,
2013
edition of the "Chinese residents dietary nutrient reference intake" is no longer for cholesterol intake to set a ceiling. Although high-cholesterol foods (e.g. egg yolks, animal viscerals, etc.) have long been considered one of the risk factors for cardiovascular disease, numerous studies have shown that cholesterol intake is not necessarily associated with cardiovascular disease. "This change does not mean that cholesterol is completely harmless, but it is not considered harmful enough to limit it, but cholesterol remains one of the potential threats to cardiovascular health."according to an analysis byFruit Shell.com, blood cholesterol has different forms, with
LDL-C
being the most commonly mentioned health risk indicator, often referred to as "bad cholesterol." Since the

1970s, a number of studies have found that levels of this
LDL-C
are directly associated with the risk of arteriosclerosis and blockage of cardiovascular vessels. On the other hand, HDL cholesterol (
HDL-C
) is known as "good cholesterol" and is considered to indicate a lower health risk. It is this principle that statins used to lower "bad cholesterol" reduce cardiovascular risk in patients with coronary heart disease. However, studies in recent years have suggested that the relationship between lipids and disease is not so simple. A study published in the New England Journal of Medicine found that in familial high-cholesterol patients who combined drugs to "strengthen fat reduction", the indicators of atherosclerosis did not improve further, suggesting that further research is needed to link this link.High cholesterol food or can not let go of eating Huang Yufang introduced, usually the blood cholesterol is divided into endo-origin and exo-origin, endo-cholesterol is the human liver and extrinsic tissue synthesis, accounting for about
80% of total plasma cholesterol
, extrotic cholesterol is ingested through food, accounted for about
20%
, it can be seen that the effect of diet is not the main, its own fat metabolism on blood cholesterol is far greater than the effect of dietary cholesterol intake."Cholesterol intake is no longer capped, does not mean that egg yolks, seafood, animal offal and other high-cholesterol foods can be 'let go of eating', the guidelines emphasize the control of saturated fatty acids in the diet, the saturated fatty acids required to provide no more than
10% of the total energy
, if you eat a lot of meat, eggs, guts, then saturated fat is easy to exceed the standard. Huang Yufang pointed out that although the U.S. and Chinese guidelines no longer limit dietary cholesterol intake, people with hypercholesterolemia still need to control dietary cholesterol. Many studies have shown that the effect of body fat metabolism on blood cholesterol levels is much greater than that of cholesterol in the diet, but the effect of dietary cholesterol raising serum cholesterol is closely related to saturated fatty acid intake.experts suggest that for the average healthy person, there is no need to specifically limit cholesterol intake. For patients with high blood lipids, due to the body fat metabolic energy is affected, or need to pay attention to control the intake of cholesterol in the diet. "For many people, there is no need to pay too much attention to the daily diet of cholesterol, if blood cholesterol is not high, an egg a day is not to worry about high cholesterol,
2016
version of the Chinese People's Dietary Guidelines also advocate eating eggs do not abandon egg yolks, egg yolks rich in nutrients, rich in lecithin, an egg a day will not increase the risk of heart disease." (Yan Huifang, Wenwen)
