Cholesterol is widely found in the body, especially in the brain and nerve tissues. Cholesterol is also high content in the kidney, spleen, skin, liver, and bile.
Cholesterol is mainly synthesized by the liver and adrenal glands, and only 10 to 20% of cholesterol is obtained directly from food.
For example, an adult weighing 70 kilograms has about 140 grams of cholesterol in his body, and about 1,000 mg is renewed daily.
His body can synthesize 800 grams of cholesterol, and the other 200 mg needs to be obtained from food.
Eating one egg a day can satisfy the body's need for cholesterol.
The cholesterol in eggs is mainly concentrated in the yolk. A medium-sized egg weighs about 50 grams and contains about 230 mg of cholesterol.
Studies have found that although eggs contain more cholesterol, they are also rich in lecithin.
Lecithin can break down cholesterol into small particles and suspend them in the blood, thereby preventing the deposition of cholesterol in the blood vessel walls.
Scientific research has confirmed that eating 2 to 3 eggs a day will only increase the cholesterol in 100 ml of blood by 2 mg to 3 mg, and will not increase total cholesterol and low-density lipoprotein cholesterol.
