Cholesterol is a natural substance found in every cell in the human body, necessary for normal body functioning. Most of the cholesterol is produced in the liver, but also get through some foods containing animal fats (saturated fats).
Cholesterol has important functions:
- INVOLVED IN THE FORMATION OF BILE ACIDS REQUIRED FOR THE DIGESTION OF FAT.
- IN THE SKIN, BY THE ACTION OF SUNLIGHT, IS CONVERTED INTO VITAMIN D, ESSENTIAL FOR GOOD BONE HEALTH.
- THE BODY USES CHOLESTEROL TO PRODUCE CERTAIN HORMONES, SUCH AS SEX AND THYROID.
When certain forms of cholesterol are found in excess, can cause damage to health.
Triglycerides are synthesized in nearly all cells of the body, but mainly in the liver, from fats from food. Therefore, the amount of dietary fat influences triglyceride levels. Excesses are deposited in adipose tissue, and can also do so in the arteries, blocking them in the same way as cholesterol. So when are elevated are a cardiovascular risk factor.
What about cholesterol and other fats?
When upset the balance between blood fats, also called lipids, it is said that there has been a dyslipidemia. Dyslipidemia when there may be some excess harmful fats or when low levels of other beneficial ones.
Cholesterol from food or produced in the liver is transported in the blood to the organs that need it. In this type of cholesterol is called LDL, “bad”, because when in excess can clog arteries and cause cardiovascular disease. must be taken to keep it LOW, reducing the amount of fats of animal (saturated fats in meats, cold cuts , cheese, nonfat dairy, etc..) and trans fats in the diet.
Trans fats are vegetable but industrially processed to improve your life, taste and texture. Preparations are widely used in pastry and industrial bakery, cookies, sandwich cookies, puddings, pies, fries, burgers, margarine and many packaged foods. Therefore, it is necessary to carefully read food labels: although they have no animal fats, and therefore, have no cholesterol, trans fats may have: they appear on labels as “hydrogenated vegetable oil”. At home, fried performed at very high temperatures and also transform oil recycling vegetable fats trans fat.
Foods containing trans fats can increase blood cholesterol. Trans fats raise bad cholesterol.
HDL, “good” is that which was not used by the body cells and back to the liver for excretion storage or out through the bile. This type of cholesterol helps keep arteries clear, reducing the risk of cardiovascular disease, so it must be taken to keep HIGH.
Good health depends not only on the levels of each type of cholesterol taken separately, but the balance between them.
