In the case of poor nutrition, it happens that the increase in cholesterol that we call "bad" LDL occurs and the "good" HDL cholesterol that is protective and sweeps the bad that covers the blood vessels is not increased. Taking into account diabetes, the excess glucose produced in the body, glycosylates the LDL particle, which also obstructs the passage of blood flow through the vessels.
