Combustion products from gas stoves are specifically implicated in asthma. Children in houses with gas stoves have asthma at higher rates and the effect is not small. People with electric stoves cook too, but their children get less asthma.

  "Our meta-analyses suggest that children living in a home with gas cooking have a 42% increased risk of having current asthma, a 24% increased risk of lifetime asthma and an overall 32% increased risk of having current and lifetime asthma." https://academic.oup.com/ije/article/42/6/1724/737113 https://academic.oup.com/ije/article/42/6/1724/737113

    The study is based on exposure to nitrogen dioxide, a by-product of combustion, not particulate exposure. High temps are needed for NOx production, so presumably electric stove tops aren't going to be generating NOx.

      The study has multiple parts. The part of the study I quoted is not specific to nitrogen dioxide, but a general conclusion about the combined effects of all of the properties of gas stoves. The study does not have enough information to conclude that the effect is entirely or even mostly caused by nitrogen dioxide in particular, or any other single cause. I did not claim that particulates are the cause. The point is that gas stove combustion products are harmful to children and probably everyone.

I guess what I have is personal experience measuring things. Maybe people with gas stoves burn their food more because of the higher potential heat?

  Perhaps the higher heat has something to do with it. I still suspect that not all particulates are made equal, so even though burning food makes more PM2.5, perhaps the particulates from the gas combustion are worse for us in some way. Still, I try to avoid any of it! I have an induction stove, but now do things like skin-on salmon in the air fryer because it produces basically no smoke, whereas it used to smoke my house out when I did it on the frypan. Requires a lot less supervision than to stop it burning in the pan too, which is nice (but perhaps I was always just doing it on too hot a pan)...

    If your gas is burning yellow, it is producing soot. If it is burning blue, it is producing very little soot. (the yellow you see is actually hot particles of soot glowing, but at a much lower temperature than the gaseous fuel-air mixture which glows blue. Gas flames can just get pans quite a lot hotter than electric or induction, generally.

      I have both gas and induction. I don't think it makes sense to cook higher than 250C, because all oils will burn at that temp. And the induction works surprisingly well in this conditions, subjectively seems to be even better than gas (faster heating, better heat uniformity), did not expect that.

      >Gas flames can just get pans quite a lot hotter than electric or induction, generally. This claim doesn't really pass the smell test for me. My induction burner gets plenty hot really fast, much warmer than I could ever practically use while cooking, even. After a quick search I was not able to find any data supporting the claim either - the only data I was able to find seemed to support induction peaking out at significantly higher temperatures than gas. Do you have any data on gas vs induction- max temperatures?
