Vitamin C or ascorbic acid has been referred to as the 'wonder worker'. It is an antioxidant and its primary role is to neutralize free radicals. Since ascorbic acid is water soluble, it can work both inside and outside the cells to combat free radical damage.
Free radicals are charged molecules. They seek out an electron to regain their stability. If they come across an LDL particle they combine with it, oxidizing it, making it much more capable of penetrating the artery wall and distributing its cholesterol there. This forms the fatty plaques and constricts artery blood flow. In the later stages, the plaques may break off and clog the artery creating a heart attack.
Nature Vitamin
Vitamin C is an excellent source of electrons - it is an antioxidant; therefore, it can donate electrons to free radicals and neutralize them stopping the plaque buildup (i.e. the atherosclerotic process).
Large concentrations of vitamin C can be found in fruits such as oranges, grapefruits, tangerines, lemons, limes, papaya, strawberries and cantaloupe. Many vegetables also pack in vitamin C including tomatoes, broccoli, green and red bell peppers, raw lettuce and other leafy greens.
Studies on the relationship of vitamin C to blood cholesterol levels report mixed results. A few human studies have noted a positive connection between the blood levels of vitamin C and high density lipoproteins (HDLs). Unlike the LDLs, which can lead to plaque, HDLs help to reduce the risk of heart disease by "scavenging" cholesterol. Conversely, a number of studies on the vitamin C/cholesterol connection concluded that the vitamin did not have a positive effect on LDL and HDL levels.
In one notable study, however, researchers monitored the blood levels of people who took 1,500 mg of vitamin C a day. They found that the cholesterol levels were reduced significantly because vitamin C encouraged the conversion of cholesterol into bile acids, which are then eliminated from the body in the feces. Similarly, several animal studies indicate that vitamin C contributes to this conversion by stimulating an enzyme that regulates the process. In addition, vitamin C may increase the beneficial HDL cholesterol.
Vitamin C might not lower cholesterol levels, but it does work to lower the accumulation of cholesterol in the cell walls.
Although Linus Pauling - the great 20th century scientist - was said to have taken 17 grams of vitamin C a day (he lived to be 93 and was very healthy), high doses of vitamin C should only be taken with your physician's approval. Vitamin C is considered to be nontoxic. However, large doses may interfere with medical tests and lower the effectiveness of sulfa drugs. Anyone with a history of kidney stones, should follow his/her doctor's advice.
