Good and bad Lipid
It is a fact that the agency needs cholesterol to make enzymes, hormones and vitamin D, which is produced mainly by the liver. However it is also well known that the cholesterol can cause plaques in arteries, when its level in sander is very high.
Types of cholesterol “good” or HDL and the “bad” or LDL. The LDL is responsible for the emergence of plaques in arteries, greater number plates, less space for that flow through the blood, increasing the risk of a total blockade and, therefore, suffering heart. The saturated fats and Tran’s fatty acids are two of the most important sources of growth of blood cholesterol, the same as that is unnecessary for the proper functioning of the agency.
The monounsaturated fats and poly-unsaturated found in some foods, such as dried fruit and fish, have the capacity to down the level of LDL in the blood. Other foods that can be consumed to achieve this objective are fruits, oats, barley and pulses, because of the soluble fiber they contain.
The cholesterol “good” or HDL takes the excess cholesterol “bad” or LDL to take it to the liver, so it can be removed, in addition withdraws part of the plates that have already been formed in the arteries. Through this mechanism cholesterol “good” is able to reduce the risk of cardiovascular disease, even more when practiced moderate exercise.
It is important to note that there are several factors that contribute to the level of blood cholesterol, among them the family inheritance, age, sex, eating habits, weight and body shape, level of physical activity and presence or absence of diabetes. While it is not possible control all in several of them can be exercised enough influence to tilt the balance in favor of health.
