Also, as always, the "New Guide" suggests that the American people should move from animal-based diet to vegetable-based diets, and eat more vegetables, fruits, nuts, whole grains and seafood! In response, the reporter invited Nanjing experts to comment and interpret.
Does not limit cholesterol intake
One of the major changes in the New Guide is the removal of the limit on cholesterol intake, which means that there is no need to worry about eating more eggs.
High cholesterol in the blood is a risk factor for cardiovascular and cerebrovascular diseases. Therefore, the United States' 2010 Diet Guide recommends that cholesterol intake should be less than 300 milligrams a day, equivalent to two small eggs.
Why is the New Guide no longer targeting cholesterol?
The reason is that although cholesterol levels are very closely related to cardiovascular and cerebrovascular diseases, this is only "cholesterol levels in the blood," and a number of studies have shown that the amount of cholesterol consumed by people, and the level of cholesterol in the blood, are not directly apparent. relationship.
Why is it so?
In one case, when we eat high-cholesterol foods, the small intestine only absorbs a small amount of cholesterol.
Second, the absorption of dietary cholesterol and its impact on blood lipids, because each person's genetic and metabolic status is different, and there is a greater individual differences, some people's cholesterol intake is high, but inhibit their own cholesterol synthesis.
In three cases, when the body is working properly, the liver itself will constantly adjust itself to prevent the accumulation of low-density lipoprotein and the cholesterol it carries in the blood.
In short, for most healthy people, the intake of cholesterol in food does not directly reflect the level of cholesterol in the blood.
Eggs can also lower cholesterol
American nutritionists extracted lecithin from eggs, allowing patients with cardiovascular disease to eat daily. After 3 months, the serum cholesterol level of patients dropped significantly. In order to treat atherosclerosis, they also received unexpected results.
The reason is that lecithin is a very strong emulsifier, can make cholesterol and fat particles smaller, and keep the suspension state, is conducive to lipids through the blood vessel wall, used by the organization, so that the blood cholesterol.
Therefore, among the foods listed in the "New Guide" that can be "eat more," eggs are among them.
Of course, for people already suffering from hyperlipidemia, the intake of cholesterol in the diet may affect the level of cholesterol in the blood and still need to be restricted in the diet.
Do not eat meat eggs will prevent nutritional balance
Lean meat, in the "new guide", is also listed in the "can eat more" list.
Why is it so?
The main spirit of the "New Guide" is to select foods to pay attention to diversity, because each type of food contains nutrients that have their own characteristics. There is no natural food that can meet all the needs of the human body for nutrients (6 for breast milk) Except for babies of the month).
Lean meat, generally refers to pigs, cattle and other livestock are rich in protein, meat, protein in these meat is a high-quality protein, very in line with the body's nutritional needs.
People can eat eggs with confidence
