Is it true that milk and its by-products contain cholesterol?
This cannot be denied, but it must be remembered that there is a special substance in milk, idrossimetilglutarato, that seems to favour the lowering of cholesterol and of fat in the blood; besides because of the fact that the average quantity of cholesterol is modest, about 80 mg of cholesterol per 100 g of cheese, this cannot be considered a limiting factor for its consumption.
