Cholesterol is a lipid molecule which is produced by all animal organisms but in humans it is mainly produced by the liver and then transported in the blood or in the brain, also used for the production of bile.
The cholesterol in our blood is not free at all, as it is not water soluble but rather bound to lipoproteins, which are divided into HDL, LDL and VLDL, i.e. lipoproteins of high density, low density and very low density.
But what is LDL cholesterol?
The major cardiovascular risk factor is represented by LDL, whose task is to transport cholesterol from the liver to the cells of the body, thus passing through the arteries, but if they are oxidized, the proteins could give rise to atheromatous plaque. which is responsible for arteriosclerosis, or the pathology that can cause thrombosis.
HDL lipoproteins, on the other hand, act in a totally opposite way by bringing cholesterol molecules from the arteries back to the liver.
Cholesterol represents a vital molecule for humans since it is the basis for the formation of certain hormones and vitamin D. In addition, we speak of the precursor of bile acids which is also involved in the formation and repair of all cell membranes. It therefore follows that only too high levels of LDL cholesterol can represent a serious alarm signal.
How do you know you have high cholesterol?
In itself, this pathology does not cause any symptoms in the patient, except in cases of homozygous familial hypercholesterolemia in which it is therefore noticeable from an early age, but there are signals that trigger the alarm such as the deposit cholesterol in the tendons and in the cornea but also the lipid plaques inside the knees and elbows.
The causes of hypercholesterolemia can however also be food and among the different foods to limit or even avoid completely we find:
-Simple sugars;
– Pasta, rice, refined cereals and bread;
-Coffee;
–Milk and yogurt, especially whole;
-All animal fats such as butter, lard and cream;
-The entrails of animals such as the liver, kidneys and brain;
– Fat cold cuts;
– Alcoholic beverages;
–All types of cheese;
– Dark vegetable oils such as palm oil.
Unfortunately, in this list of foods to avoid we also find fruits, (not all of them), but only those which, containing a high percentage of carbohydrates and fructose, contribute significantly to raising already high cholesterol levels. It is therefore advisable to be very careful not to take any: apples, cherries, pears, grapes, dates and dried figs.
