Although a large amount of cholesterol in your body can be bad for your health, it is still a very important compound in your body. Cholesterol is responsible for a variety of bodily processes.
For instance, cholesterol is an important precursor for sex and steroid hormones. It also provides structural support for every cell in our body, since cholesterol is a key component of cell membranes. Additionally, cholesterol is also needed to make the myelin sheath, which coats our nerve cells. Even though there has been a strong link established between high cholesterol and heart disease, we still need some cholesterol in our bodies.
On average, the liver makes approximately 80 percent of the cholesterol needed to carry out necessary processes in the body, and the rest comes from the diet.
Your daily consumption of cholesterol should not exceed 200 mg a day. However, the liver is capable of making all of the cholesterol needed to meet our daily requirements, so none of it really needs to come from the diet.
