We all know that cholesterol mainly comes from the body’s synthesis, mainly from food, but high cholesterol is not good for the body, will cause hypercholesterolemia, which will form coronary atherosclerotic heart disease, so the intake of cholesterol must be moderate, not too much and too little, so we know how cholesterol comes from, now let me tell you how cholesterol comes from it. We must eat a reasonable diet and take active precautions against diseases so that we can have a good body. Cholesterol in its solid state is generally a colorless crystal, which is widely present in the body of animals, but is most abundant in the brain and nerve tissue. The amount of cholesterol in the human body is generally 0.2% of the body weight, with the liver and skin having the highest content. There are two sources of cholesterol in each person’s body, one is produced by internal metabolism, which accounts for about four-fifths of the total, and the other is obtained from food, which accounts for about one-fifth of the total, so the daily cholesterol supplement should not be too much. First of all, cholesterol is a substance that exists in the cells of animal tissues, like some fish, animal offal and squid, which will synthesize cholesterol after entering the human body, some of which will be metabolized out of the body and some will stay in the body to form bile acids, constitute cell membranes and synthesize hormones. 2.Secondly, cholesterol mainly exists in foods, mainly among pig brain, pig liver, pig lung, pig spleen, every animal, and shellfish, like fresh shellfish and red shellfish, and finally, some cream, butter, suet and lard which all suffer from cholesterol. Lastly, we should eat a reasonable diet to lower cholesterol, eat less fatty meat and meat and oil, and eat more vegetables and fruits and algae, like fungus, kelp and wakame so that cholesterol will not increase, and cholesterol can even trigger the occurrence of gallstones, so we should match our diet reasonably. 4, pay attention to cholesterol must pay attention to diet, eat less cholesterol-rich food to avoid disease, usually more exercise, digestion of cholesterol, after all, good habits to have a good body. 5, in the daily life diet, there is no need to deliberately supplement the cholesterol intake, because most of the cholesterol is synthesized by its own metabolism, such as a 70 kg adult, her cholesterol content is about 140 grams, so the cholesterol in food is a secondary supplement. 6.Everyone eats a wide variety of food every day, which can be said to be very different, but the demand for cholesterol is very little, and the amount of cholesterol intake from food per person per day can be said to be only 200 mg, which can meet their own needs and ensure the health of the body. 7. If a person consumes a large amount of cholesterol, it is usually considered to increase the absorption of it, but in fact, if too much cholesterol is consumed, on the contrary, its absorption rate tends to decrease, so the daily intake of cholesterol for adults should not exceed 300 mg at best. Note: Whatever it is, there should be a proper degree, so it should not be supplemented too much, let alone too little. This requires us to pay attention to our usual reasonable diet, and adhere to reasonable exercise, and eat more fish and foods rich in plant fiber can effectively control the amount of cholesterol stored.
