Cholesterol, essential for the body

Cholesterol is a fat brought in for one third by the diet (exogenous origin) and two thirds made by the liver (endogenous origin). The liver is able to produce 1g of cholesterol per day from proteins, fats and carbohydrates! One can assimilate cholesterol to a particle of fat that moves in our body via the bloodstream.

Cholesterol has several functions:

  • To constitute the membranes of the cells of our body;
  • Direct the development of certain fetal cells;
  • Participates in the formation of synapses;
  • It is an ingredient of bile;
  • Precursor of vitamin D;
  • Is part of body fat.

Note: there is  only one cholesterol but two cholesterol transport systems in the blood  !

Origin cholesterol

The good cholesterol

The  HDL  (High Density Lipoproteins), known as the “good cholesterol”, recover the excess cholesterol and carry it back to the liver where it is processed before being eliminated.

The bad cholesterol

The  LDL  (Low Density Lipoproteins), transport cholesterol from the liver to all cells . When this beautiful machine breaks down, LDL-cholesterols accumulate and can contribute to the formation of plaques that gradually clog the arteries.
