Folic acid

From my last pregnancy I know that neural tube defects can be prevented in pregnancy by taking folic acid. I took mine religiously last pregnancy and I'm going to start taking it now since I may potentially get pregnant soon. Not sure if I need a prescription for it here in France, but I found a list of foods that have good quantities of folic acid:

Fortified breakfast cereals such as Total and Product 19
Lentils
Asparagus
Spinach
Black beans
Peanuts (only if you do not have a peanut allergy)
Orange juice (from concentrate is best)
Enriched breads and pasta
Romaine lettuce
Broccoli

I eat those foods quite a lot anyway so I think it's good. But in an effort to manage this next pregnancy well I think I'll start my supplements this week.
