Oxidized LDL cholesterol is more likely to build up into plaque formations in arteries, causing arteries to narrow and harden. That plaque formation and related damage is known as atherosclerosis. If oxidation of LDL cholesterol can be delayed the risk of atherosclerosis is reduced. During the 12-week study the subjects were monitored and required to keep detailed food records. Hyson said the antioxidants in apples in addition to fiber and potassium may all help protect against heart disease.
Apples contain no fat, sodium or cholesterol.
A medium piece of fruit has only 80 calories. Previous studies have shown that the type of soluble fiber found in apples reduces overall blood cholesterol levels. Cornell University researchers reported in June 2000 that apple antioxidants inhibit the growth of certain types of cancer cells in a laboratory study. Cornell researchers reported that apples had more antioxidant capability than a 1,500 milligram megadose of vitamin C. Recent population studies associated apples with a reduced risk of lung cancer, improved lung function, reduced risk of certain types of stroke and reduced risk of coronary mortality.
