What is cholesterol milk powder ?
Cholesterol is a derivative of cyclopentane polyphenanthrene, which is an important component of various membrane structures and nerve myelin sheath of human cells. A normal person weighing 70 kg contains about 140 grams of cholesterol. It exists widely in animals, especially in brain and nerve tissues, and is also high in kidney, spleen, skin, liver and bile. Its solubility is similar to that of fat, and it is insoluble in water.Cholesterol milk powder usually refers to low-fat, low-saturated fat or plant-based milk powder, which helps to control cholesterol levels by reducing the intake of cholesterol and saturated fat.

What are the sources and absorption sources of Cholesterol ?
Source and absorption source:
(1) Exogenous comes from dietary cholesterol. (2) Endogenous comes from the human body's own synthesis.
Absorption: It is absorbed in the intestine and mainly synthesized in the liver, skin and intestinal mucosa. Cholesterol in the diet is absorbed into the blood in the form of chylomicrons. The absorption of cholesterol also depends on the intake. When the intake is high, the percentage of absorption will be reduced, and the absorption of cholesterol by people will be less than 10% when the intake is high. After free cholesterol is absorbed, 2/3 of it quickly combines with fatty acids to form cholesterol ester, which increases the ability of lipoprotein to carry It. After Cholesterol milk powder enters cells, it is hydrolyzed and defatted by acidic lipase in lysosomes. Part of cholesterol is converted into steroids in cells. Excess It is directly excreted into the intestine; Part of it is oxidized into bile acid in the liver and excreted with bile.
What is the main function of Cholesterol?
It in the body has free type and lipid-bound type (cholesterol ester).
1. Cholesterol can be used as emulsifier, raw material of artificial bezoar, vitamin D, liquid crystal and synthetic hormone, and also as analytical reference substance for biochemical research.
2. It can also be used for the flocculent test of cephalin cholesterol. It is the main component of biofilm, and about 25% of total cephalin is cholesterol.
Cholesterol milk powder has the following functions
(1) participate in the formation of cell membranes.
(2) It is the raw material for the synthesis of bile acids, vitamin D and steroid hormones.
(3) The serum total cholesterol of normal people in China is about 182.5 4.3 mg%. cholesterol metabolism may be impaired. The serum cholesterol content of patients with coronary atherosclerosis is often high. Therefore, the determination of serum cholesterol content in clinical laboratory will help to diagnose some diseases.
Foods with low cholesterol are:
Lean meat, rabbit meat, yellow croaker, hairtail, skinless chicken, carp, shredded eel, square ham, white fish, jellyfish skin, milk, sea cucumber. Foods containing high Cholesterol milk powder (the number of milligrams of cholesterol per 100 grams of food is in brackets); The brain content of animals is the highest: such as pig brain (3100 mg), cow brain (2670 mg) and sheep brain (2099 mg). Followed by poultry egg yolk: such as salted duck egg yolk (2110 mg), egg yolk (1705 mg), quail egg yolk (1674 mg) and preserved egg yolk (1132 mg).
Foods high in cholesterol:
Animal foods contain high cholesterol, such as meat, eggs, milk, etc., while plant foods do not, such as vegetables and fruits, and beans contain almost no Cholesterol milk powder, so if people with high cholesterol should avoid animal foods, it is better to choose plant foods. Its content in animal viscera is particularly high, such as pig lung, pig kidney, pig liver, pig intestine, pig spleen and so on, which all contain high cholesterol, so we should eat less. The content of animal brains is also very high, especially pig brains, followed by cow brains, sheep brains, duck brains, chicken brains, etc., so we should eat less brain foods to prevent high cholesterol.
