My wife pointed out and I feel dumb for not realizing it because I know this myself, you never heat baby food much past 30 seconds, certainly not for 3 minutes at highest setting. Babies generally eat baby food at room temperature to body temperature, and anything outside that is considered extreme to a baby's sensitive nervous system, not to mention you wouldn't want to risk lava spots that might burn their mouths.…

I wonder how it went when our ancestors heated food for babies to eat on a burning camp fire? Was that a factor in high child mortality?

What about the heavy metals that are part of the cast iron and steel though? What about the heavy metals in ceramics? The list is pretty endless, but very specific types of glass (boron silicate or pyrex) and titanium can be good to switch to, as long as you are very careful about not getting lead or uranium glass. Or you could just not buy that lead testing kit or Geiger counter and live in ignorant bliss. People li…

But there isn't lead or other heavy metal in the cast iron itself. If there are heavy metals, they are found in the glazing, so the best thing to do is buy pure cast iron, not glazed cast iron. The same goes for ceramics, but you can't really buy ceramics without glazing, because the ceramic itself is porous - I personally replaced all ceramics with glass and stainless. Just as a single data point, all our kitchenwar…

This comment is unhelpful; the person you're replying to clearly is not claiming that "absolutely everything that's harmful in large doses is harmful in small doses." > Unrealistically high doses imply absolutely nothing about lower doses. The example they give of nuclear radiation is a clear illustration of how a useful hint can be drawn from the high-level example of harm, a pattern which microplastics might very w…

Models can breakdown at huge scales because they introduce other non-representative factors or nonlinear responses. Sending an astronaut to the center of the Sun and concluding their death is from radiation would be a pretty bad model. Hitting a person with a car would be a pretty bad model for a fly landing on them. The first model is bad because the sun is doing more than just exposing them to radiation. The second…

Stainless does have problems leeching nickel (and sometimes chromium), especially after being cleaned by an abrasive, or cooking acidic foods, which is common. This happens to an extent to cause allergic reactions in people. Also silicone products are commonly mixed with plastic fillers that have the same issues as normal plastics. Pure platinum cured silicone products are premium products and somewhat rare.
