Final answer:
Vitamin B6, folate, and vitamin B12 play important roles in reducing the risk of coronary heart disease (CHD) by decreasing homocysteine levels. Including food sources rich in these vitamins in your diet can help reduce the risk of CHD.
Step-by-step explanation:
Vitamin B6, folate, and vitamin B12 play important roles in reducing the risk of coronary heart disease (CHD). Vitamin B6 helps in the metabolism of homocysteine, an amino acid that, when elevated, is associated with increased risk of CHD. Folate and vitamin B12 are involved in the conversion of homocysteine to methionine, a non-toxic amino acid, thereby reducing homocysteine levels and decreasing the risk of CHD.
Research has shown that individuals with low levels of these vitamins have a higher risk of CHD. Including food sources rich in vitamin B6, folate, and vitamin B12, such as whole grains, leafy greens, legumes, lean meats, and fortified cereals, in your diet can help reduce the risk of CHD.
