Cholesterol is a yellow fatty substance and a main ingredient in the digestive juice bile, in the fatty sheaths that insulate nerves and in hormones like estrogen and androgen. It performs functions like transportation of fat, provides defense mechanism and protects red blood cells and muscular membrane of the body.
Most of the cholesterol seen in the body is produced in the liver. Foods that reduce bad type LDL cholesterol include almond, apple, avocado, beans, carrot, coriander seeds, fenugreek seeds, garlic, grapefruit, grape seed oil, ishabgul, oats, olive oil, onion, soyabeans, sunflower seeds and wallnuts.
Foods can lower LDL cholesterol and raise good type of HDL cholesterol and prevent the oxidation of LDL cholesterol that is destructive to arteries. Antioxidants may also help keep bad type LDL cholesterol from becoming oxidised and harmful to arteries.
