He talks about North Carolina which has the highest percentage of neural tube defects, which leads to Spina Bifida, in the United States. This comes out to be 1 in 33 babies born in North Carolina.

Folic acid is also known as the chemical folate which is a B vitamin, known as B9. It is found in many different types of foods, such as multivitamins, leafy greens, vegetables, beans and many more, some of which you can see below in the graphic. When this chemical is found in food it is called folate. Folic acid is hard to absorb through foods because how the digestive system processes it. Only about half of the amount of it that is consumed in food is absorbed. The biggest thing to remember is that absorption is different for everyone and it can depend on how the food is cooked or what food it is.
The hardest thing about Folic Acid is that the researchers studying its effects do not know why it helps the neural tube defects or if it could help with other birth defects. In the united states, the FDA has suggested that women take folic acid daily in childbearing ages and in at least the first 3 months of pregnancy.
