Both cholesterol fats can not dissolve in the blood : they must be transported by complex cells called lipoproteins . There are many types of lipoproteins, but the ones that interest us, in this case, are lipoproteins low density lipoprotein (LDL) and lipoprotein high density lipoprotein (HDL) .
What is LDL cholesterol?
The low-density lipoproteins are the major of cholesterol in the blood . If too much cholesterol LDL circulates in the blood can slowly build up in the walls of arteries feeding the heart and brain. Together with other substances it can form plaques, thick, hard deposit that can clog the arteries, in which case we face the problem known as atherosclerosis.A blood clot (thrombus) may form around these plaques in the arteries leading to the heart, blocking blood flow and cause a heart attack. If the clot blocks blood flow to the brain, you can get the stroke. At a high level of cholesterol LDL (> 160 mg / dL) is a high level of risk of diseases heart. For those suffering from heart level cholesterol LDL should not exceed 100 mg / dL.
This is the reason why the cholesterol LDL is called bad cholesterol : low values \u200b\u200bof cholesterol LDL corresponds to a Low risk factor for heart disease.
What is HDL cholesterol?
About one-third, one fourth of blood cholesterol is carried by lipoproteins HDL. Doctors believe that HDL tends to remove cholesterol from the arteries bringing it to the liver, which is distributed to the body. Some experts believe that HDL eliminate the cholesterol in excess of the plates in this way delaying their development. The cholesterol HDL is known as good cholesterol because a high level seems to protect against heart attacks. In addition, scientific evidence would show that a low level of HDL (\u0026lt;40 mg / dL in men and \u0026lt;50 mg / dL in women) coincides with a major risk factor. Therefore, even a low level of cholesterol HDL can cause serious heart problems.What is cholesterol Lp (a)?
The Lp (a) is a genetic variation of plasma LDL. At a high level of Lp (a) is a major risk factor for premature development of atherosclerosis. The way in which a high value of Lp (a) contributes to heart disease is unclear. In addition, any micreo-lesions in artery walls contain substances that may interact with Lp (a) and lead to the accumulation of fatty deposits.Cholesterol and diet
Generally cholesterol can get in two different ways. The first is a production, mainly associated with the liver, which normally produces about 1,000 mg per day. The second is related to diet daily which can also contain significant amounts. In particular we mention the animal foods (dairy products, egg yolks, meat, fish, seafood and whole milk). Foods plant (fruit, vegetables and cereals) do not contain back cholesterol .Generally the body is able to produce all cholesterol it needs, so that an additional contribution is not necessary . Saturated fatty acids are primarily responsible for raising the cholesterol in the blood, which, remember, it increases the risk of heart disease. The power therefore plays a key role in industrialized countries, especially in countries with low consumption of fruits and vegetables, the average values \u200b\u200bof cholesterol hired through food can easily exceed 300 mg and 200 mg for men and women.
Although cholesterol excess dietary be eliminated from the body by the liver , the common trend in the medical world indicates the maximum limit of 300 mg cholesterol that the human body can take daily. In the case of heart problems such amount should not exceed 200 mg. A simple rule can help do this: avoid foods with high levels of saturated fat , which generally contain high levels of cholesterol , can significantly reduce the 'intake of cholesterol .
Who is in a state of high values \u200b\u200bof cholesterol should further reduce the intake from foods. Since the cholesterol is in all animal foods, a diet should be based on rigorous daily limit of 150 grams of lean meat or fish and low fat dairy products. Recall that protein especially vegetables and legumes are of high quality and therefore valid substitute for animal protein.

Physical activity and cholesterol
A exercise regular increases cholesterol HDL, lowering the risk factor of heart disease. Exercise may also help in control or pes of diabetes and high blood pressure. L ' aerobic exercise benefits the heart and breathing. Daily moderate-intensity physical activity such as brisk walking or swimming is therefore surely desirable.Even physical activities low intensity , if daily, help reduce the risk of heart problems. They include activities such as walking for pleasure, gardening, housework, dancing, etc. ...
Tobacco and cholesterol
Smoking is one of six factors at higher risk for heart disease. Smoking lowers cholesterol HDL and increases the chances of clots in blood.Alcohol and cholesterol
In some studies, moderate use of alcohol showed a relationship with high levels of cholesterol HDL. However, due to very high risk of other , especially if one makes use of spirits, and the modest benefits to the cholesterol is highly recommended not to use them.If you already have use of alcohol and you can not avoid it, consumed in moderate quantities. A moderate use of wine (an average of one or two drinks per day for men and one drink per day for women) lowers the risk of heart problems than those who did not use. Make sure, however: the use of alcohol can lead to other health hazards, such alcoholism, high blood pressure, obesity, cancer, suicide , etc.
