Low Folate Also Increases Your Risk of Heart Disease and Stroke.
In addition to its role in producing blood cells, folate is also important in preventing a potentially toxic amino acid from building up in the body. The amino acids in foods are an essential part of our diet, but not all are beneficial. Homocysteine is an amino acid that occurs naturally in your blood. You can also get it from eating red meat. Folate, along with vitamins B6 and B12, helps break down the amino acid. When levels of homocysteine are too high, it can have a damaging effect on the brain, heart, blood vessels, and bones. High homocysteine levels can damage the linings of arteries, making it harder for oxygen-carrying blood to travel from the heart to the rest of the body and increasing heart attack risk. At high enough levels, homocysteine is linked to a higher risk of heart disease, dementia, and stroke. Increasing folate intake can help keep homocysteine levels low to protect your heart and brain health.
