Folic Acid

Folic acid is widespread in the food supply, with the highest concentrations in liver, yeast, leafy vegetables, fruits, and legumes. It is now also fortified in grain products (breads, cereals, spaghetti) within the United States, where fortified foods deliver approximately 140 micrograms of folate per 100 grams of food. It is easily destroyed through common household food preparation techniques and long storage times, so it is often most highly concentrated in fresh foods.
