Prep Tip
Light cooking actually increases how much iron and calcium your body can absorb, since heat breaks down the oxalates that bind them.
Absorption Boost
Vitamin C foods — significantly improves absorption of spinach's non-heme iron
Healthy fats — helps absorb spinach's fat-soluble vitamin K and lutein
Use Caution If
You're prone to kidney stones — spinach is one of the highest-oxalate vegetables
You take blood thinners — very high vitamin K content; keep intake consistent
Storage
Refrigerate in a breathable bag; use within 5 days, as leaves wilt and lose vitamin C quickly.
