Stop using cast iron pans! Here are four things to know about iron: 👇🏼1. Too much can increase your cancer risk: High iron levels are associated with an increased cancer risk, likely because of iron's ability to make free radicals, which damage DNA. 2. You probably aren’t deficient: Unless you’re losing a lot of blood or you’re on an extreme diet, you probably have enough iron in your body.3. Copper deficiency can make you iron deficient: Because you need copper to absorb iron, anemia can actually be caused by a copper deficiency. If you have anemia, get your copper levels checked before you start supplementing with iron. 4. Steak has more iron than kale: You knew I had to bring kale into this somehow. 🤪#Kale #Iron #Iroevels #Castironpan #Cooking #Bulletproofdiet #Biohacking #Biohacker #Daveasprey
