如何选择叶酸

Folic acid is the man-made form of folate, a B vitamin. 

Many breakfast cereals (in U.S.) have 100% of your recommended daily value (400 micrograms) of folic acid. Folate is found naturally in some foods. Foods that are naturally high in folate include:

* unpopulated spinach and other dark green, leafy vegetables

* unpopulated oranges and orange juice

* unpopulated nuts

* unpopulated beans

* unpopulated poultry (chicken,turkey,duck, and geese) and meat

* unpopulated whole grains

Most multivitamins sold in the U.S. contain 400 micro-grams, or 100% of the daily value, of folic acid.  Look for "USP" or "NSF" on the label when choosing vitamins. These "seals of approval" mean the pills are made properly and have the amounts of vitamins it says on the label. Check the "Supplements Facts" label to be sure you are getting 400-800 micrograms of folic acid. Some brands list the word “folate” on the label, others use “folic acid,” but either term is okay as long as the supplement provides 400 mcg.



1 mcg DFE = 0.6 mcg folic acid and 1 mcg L-5-methylfolate = 1 mcg folic acid
