Healthy diet is always the goal we pursue, only healthy eating habits are more conducive to health. Some people say that a healthy diet means a light diet, but this is actually very partial. To maintain the normal functioning of the body, the diet must be balanced in terms of nutrition. A single vegetarian diet is also bad for your health. This is not always a light diet, cholesterol still appeared “burst”, let a person some doubts! Why is this? 1, the source of human cholesterol is mainly synthesized in the body and food intake, of which 70-80% is synthesized by the liver, while the cholesterol in animal offal, egg yolk, cream and meat and other foods only accounts for 10-20%. The cholesterol eaten only accounts for about 20% of the cholesterol in the blood, that is, 80% of the cholesterol in the blood has little to do with eating, but is synthesized by the body itself. Endogenous cholesterol is 99% secreted by the liver and accounts for most of the total cholesterol, about 70-80%, while exogenous cholesterol is obtained from outside foods and only accounts for 20-30% of the total cholesterol, and exogenous cholesterol decreases as the intake increases. 3, genetics may be a cause of high cholesterol, there is a disease called familial cholesterolemia, a lifetime, the blood cholesterol is particularly high, and at a very young age, due to high cholesterol, resulting in serious atherosclerosis, or even heart attack or sudden death. 4.If you usually exercise less, even if you eat a light diet, but because you eat more and consume less, obesity and high cholesterol may occur. 5, cholesterol is metabolized at night, if often stay awake at night or often on night shift, easy to high cholesterol. 6.Some drugs. Certain drugs can increase triglyceride levels and lower HDL (good cholesterol) levels, such as diuretics, beta-blockers, estrogen and adrenocorticotropic hormones. Therefore, a person’s high or low cholesterol is not entirely determined by diet, but also by the overall body composition, DNA, liver health, usual diet and exercise. In the future, we should pay attention to a balanced diet, and we can eat some meat, preferably fish, followed by chicken. Try to eat coarser staple foods, reduce fine grains, and not eat light, there is no problem.
