A well-balanced diet, such as the DASH diet, significantly lowers blood levels of homocysteine, a by-product of protein metabolism. This reduction is predicted to lower the risk of heart disease by 7 to 9 percent. Additionally, reductions in blood pressure and cholesterol from the DASH diet should further reduce heart disease risk.
The DASH diet, known for its blood pressure-lowering effects, also reduces homocysteine levels, a risk factor for heart disease. Participants on the DASH diet had lower homocysteine levels compared to those on a control diet or one rich in fruits and vegetables.
