Folate is a B vitamin also known as folic acid. This is vitamin is important for birth defect prevention and healthy pregnancy. Vitamin B12 and folate combined help the body metabolize homocysteine, which is a sulfur-containing amino acid derived from methionine that is normally present in blood, according to the Office of Dietary Supplements. If levels of homocysteine become elevated, your risk for cardiovascular disease increases. Iron is an important nutrient for the delivery of oxygen to the body. If levels were to become low, anemia can develop, which causes low energy levels, fatigue and shortness of breath. Learn what foods to include into your diet to avoid any health complications.

Fish
Select varieties of fish and shellfish contain B12 and iron, but they do not contain folate. Oysters, clams, trout, salmon and sardines all have at least 50 percent of the daily value for these nutrients. Salmon is also high in omega-3 fatty acids, which are beneficial to heart health.
