Can you find a source that provides any scale for how much over the recommended daily 8-28mg (men vs. women) is required to cause long-term concerns? All I can find online is for acute iron poisoning which is usually when a kid wolfs down a bottle of supplements.

If you’re curious, Wikipedia says iron poisoning happens at around 20-60mg/kg or 1.8-5.4g for a 90kg (200 pound) person. That’s like 3/4 of an M&M’s worth of pure easily digestible iron which is a shitload.

I’ve never heard anyone talk about any negative health impact of cooking with iron (which people have been doing for literally thousands of years), so I’m curious.
