Key Evidence Takeaways:
- Legumes are nature's richest plant folate sources: 1 cup of cooked edamame provides 482 mcg DFE (120% DV); 1 cup of lentils provides 358 mcg DFE (90% DV).
- Dark leafy greens (spinach, asparagus, romaine) provide bioavailable natural folates alongside synergistic antioxidants.
- Boiling leafy greens leaches up to 50% of folate into cooking water; gentle steaming, sautéing, or raw consumption preserves nutrients.
- Whole foods provide natural folates with zero risk of exceeding the 1,000 mcg synthetic folic acid upper limit.
