Benefits of Yams
Protection Against Cardiovascular Disease
Yams are a good source of vitamin B6. Vitamin B6 is needed by the body to break down a substance calledhomocysteine, which can directly damage blood vessel walls. Individuals who suffer a heart attack despite having normal or even low cholesterol levels are often found to have high levels of homocysteine. Since high homocysteine levels are signficantly associated with increased risk of heart attack and stroke, having a good supply of vitamin B6 on hand makes a great deal of sense. High intakes of vitamin B6 have also been shown to reduce the risk of heart disease.
