More research is needed to determine if hyperhomocysteinemia may be a risk factor to heart disease, but if it is, then that’s just another reason to eat less meat (1). Eating meat increases levels of homocysteine in the blood (1). Leafy greens and a variety of fruits in the diet supplies folic acid and B vitamins, which help break homocysteine down (1). Vitamin B12 (almost exclusive to meat) helps as well so choosing to give up meat entirely is not advisable (1).
