Everything you know everything about cholesterol

Among the enemies of the arteries, cholesterol is specifically about him and everyone has his own ideas on the subject ... 9 questions simple and practical to understand everything about this heartbreaker and overcome preconceptions.

1. What is cholesterol?

CholesterolIndispensable the functioning of the body, cholesterol is a fat made by two-thirds by the liver and provided to third from food. Present in the cell wall, cholesterol gives them flexibility and strength. It also provides protection from external aggression. To reach the various organs, cholesterol uses carriers that allow it to circulate in the blood. HDL (High Density Lipoproteins), known as "good cholesterol", recover the excess cholesterol and bring it back to the liver where it is processed before being eliminated. LDL (Low Density Lipoproteins), carry cholesterol from the liver to all cells. When LDL malfunctioning or are in excess, the rate of cholesterol in the blood increases. Cholesterol accumulates and forms plaques that gradually clog the arteries. This is why LDL is called "bad cholesterol".

2. Why cholesterol increases there?

Poor eating habits in the first place (excess saturated fatty acids in particular), but also stress, genetic predisposition, certain diseases (kidney disease, hypothyroidism), taking certain medicines help to increase the rate of cholesterol blood. In addition to smoking, alcohol consumption, hypertension, diabetes, obesity, sedentary lifestyle are factors associated with high cholesterol, increases exponentially cardiovascular risks.

3. The excess cholesterol is it related to weight?

Cholesterol and weight can be linked. The extra weight, preferably fits in the upper body (neck, shoulder girdle, abdomen), accompanied very often many abnormalities: hypertension, type 2 diabetes, elevated triglycerides and cholesterol. An even moderate weight loss improves the health of people whose body mass index (BMI) is above normal.

4. Fatty foods are they to be banned permanently?

To reduce cholesterol levels, there is no mystery we must first change his eating habits. All fatty foods are not avoided. Avoid excessive intake of saturated fat and focus on the contributions of fat called "unsaturated" in the diet.

5. What do you usually "good" fats?

We must first know that there is no "right" or "bad fat" per se, since it is excessive or insufficient intake that may have adverse effects on the body.

The unsaturated fatty acids, known as "good fats" are found primarily in oils, oilseeds and fish.

Omega-3 is relevant because our modern diet is sorely lacking: these unsaturated fatty acids contribute to the efficient functioning of the cardiovascular system. They are found only in foods (they are not produced by our body) and especially in fatty fish and rapeseed oils, walnuts and soybeans.

Other unsaturated fatty acids (omega 6, omega 9.) Are beneficial: omega 6, for example, are particularly present in sunflower oil, soya or maize.

In a balanced diet, nutritionists recommend making these unsaturated fatty acids Omega 6 and Omega 3 balanced amounts in our diet (recommend: report omega 6 to omega 3 close to 5).

Today intakes of omega 3 are insufficient to achieve this balance.

6. What are the benefits of vegetables and fruits in a cholesterol-lowering diet?

Low in fat and calories, fruits and vegetables you feel fuller while providing micronutrients - vitamins, minerals, trace elements, fiber - essential to the body. They contain a number of antioxidants, which prevent the oxidation of cholesterol and prevent the formation of plaque in arteries. Combined with lower saturated fats, consumption of fruits and vegetables protects cardiovascular health.
