May improve heart health

Parsley is a nutrient-dense plant that may benefit cardiovascular health. It's a strong source of the B vitamin folate, for example, with 1/2 cup (30 grams) supplying 11% of the RDI. In certain groups, high dietary folate consumption may minimize the risk of heart disease. Comprehensive research of over 58,000 adults discovered that the greatest folate consumption was related to a 38% lower risk of heart disease. In contrast, poor folate consumption may raise your risk of heart disease. In one research of 1,980 males, those with the lowest consumption of this vitamin had a 55% increased risk of heart disease.

According to some scientists, folate helps heart health by reducing levels of the amino acid homocysteine. In certain studies, elevated homocysteine levels have been related to an increased risk of heart disease. Homocysteine can harm your heart by affecting the structure and function of your arteries. However, the link between this amino acid and cardiac disease is still debatable.
