Claim Breakdown:
📝 Fact Check: It is true that coffee can interfere with iron absorption, but this is highly dependent on your diet! 🥦🥩 Coffee impacts 'non-heme' iron (found in plants like spinach and lentils), but has very little effect on 'heme' iron (found in meat). If you are vegetarian or prone to anemia, timing your coffee matters! ⏱️
