🔬 The science, kept simple
Folate takes its name from the Latin folium, leaf, because green leaves are where it lives. It hands out single carbon atoms for building DNA, which makes it most critical wherever cells divide fast: a baby's forming spine and brain, bone marrow making blood, the lining of the gut.
Why you need it: Healthy red blood cells, DNA repair, and, in the earliest weeks of pregnancy, the closing of the baby's neural tube... often before a woman knows she is expecting.
Daily target: About 400 mcg DFE a day; 600 in pregnancy.
📖 In Scripture
Daniel and his companions asked for pulse... seeds, beans, and greens... and water (Daniel 1:12), and were found healthier for it. Beans and greens remain the two richest folate foods on earth.

⚖️ Worth knowing
Folate is fragile: long boiling leaches it away, so steam greens lightly. Women who could become pregnant are advised 400 mcg daily from fortified food or a supplement in addition to food folate.
