This should be clear as day to anyone - burning causes toxic fumes.
PeterWhittaker•44m ago
That's why I love my induction range: all the benefits of gas (near instant heat control and response, even cooking, etc.), none of the asthma or benzene!
Forgeties79•26m ago
I’m lucky we have a proper range hood that vents outside so I feel better about gas. If this is the same paper I read a year or two ago, or related to it, apparently that reduces the “pollution” in the house by like 90% or more. Going off memory though so someone correct me if I’ve got it wrong.

If the hood breaks down or the stove needs to be fully replaced, I will probably flip to induction. I had one in my old apartment and it was great

lkramer•40m ago
I find it significantly harder to cook with electric than gas, and the first hurdle these days is always that for some reason all modern stoves use awful touch interfaces instead of just plain knobs. I don't understand how we got there. It should be obvious to anyone that it's a terrible interface when you are trying to multitask several pots and might also have greasy hands
syntaxing•35m ago
Simply not true. There’s a ton of induction and electric coil ranges with knobs. Just look at the Bosch line.
mort96•32m ago
I haven't seen one in a kitchen in decades, other than extremely old ones. The touch control design is absolutely everywhere. At least here in Norway, where ~all stovetops are electric.
XenophileJKO•23m ago
I just bought an LG induction stove, all knobs except oven temp setting.
expedition32•14m ago
I mean they probably exist but the standard induction plates that they deliver with kitchens are all touch control. You learn to live with it.
agos•30m ago
they are definitely a minority, not "tons". On the Bosch website I can't even find them.
Maxion•22m ago
Not really in Europe, at least not in the nordics. All Bosch are touch controls.

I don't care. Quality-of-life. I cook in a pan every day. Nothing but an open flame gives me the kind of control I need to cook with the precision I do. Whatever the harmful effects on my health are, that is a trade I make consciously. My life would be noticeably worse without my open-flame stove.

I'd wager anyone who opines otherwise in this thread barely cooks or doesn't cook in a serious fashion. A gas stove is a tradesman's tool.

syntaxing•37m ago
No way. I cook everyday and induction is vastly superior than gas. The only time fire is vastly superior is when I use a wok which I have a stove I use outdoors. Most induction stoves have temperature maintained too. So it can keep your oil at a specific temperature let it be frying or confit or roasting spices.
Forgeties79•30m ago
Yeah I was going to say, induction is the shit. Normal electric stove tops are a far cry from them and people should not assume they’re anything alike other than a non-flame process.
jedberg•23m ago
They have wok adaptors for induction now, FYI.
chomp•20m ago
Can’t (properly) cook a tortilla on an electric burner, though you can get subpar results in a pan

Can’t char a pepper on an electric burner

Can’t heat a nabe on an electric burner

Also during hurricane season, my gas burner still works when the power goes out.

The list goes on of things that electric simply cannot do. To claim one is superior over the other ignores a lot of the ways people cook. They are just simply different cooking tools.

warmedcookie•40m ago
Interesting. I would like to know if central heating (gas) has similar effects.
alex43578•36m ago
If it’s properly vented, no it wouldn’t. Huge difference between just running an open flame in the middle of your kitchen and HVAC applications.
fhdkweig•22m ago
Technology Connections did a video (because of course he did) on how gas furnaces work. The short of it is that the flame is contained inside of metal tubes and never mixes with indoor air. No exhaust gases can leak into the breathable air.

syntaxing•38m ago
I’ve been using induction since I have had kids and I enjoy it so much more than fire. That being said, I rent so I can only use 120V ones and the options are so limited here. Most of the small 120V ones make an obnoxious hum.
amluto•24m ago
The Impulse Labs stove has almost cartoonish levels of excessive power and uses 120V (and doesn’t even use particularly high current). The Breville Control Freak uses 120V and is a touch underpowered but is truly excellent. Both of these even have knobs (and both have very nifty temperature control capabilities).

The paper: https://doi.org/10.1093/pnasnexus/pgaf341

The numbers:

[...]

We estimate average total residential long-term NO2 exposure across the United States to be ∼10 ppbv for people who own a gas stove (∼18 ppbv or more for households in the top 5% of gas burned while cooking) and ∼8 ppbv from total outdoor exposure for those with electric stoves, which cause no additional NO2 exposure.

[...]

Stratifying exposure by gas stove use intensity (i.e. by amount of gas burned while cooking, [...]), we find that people in households burning the 5th, 50th, and 95th percentiles of fuel nationally on average are exposed to 0.03 (95% CI: 0.01–0.07) ppbv, 1.7 (95% CI: 0.8–3.5) ppbv, and 10.3 (95% CI: 4.8–21.7) ppbv, respectively, of additional NO2 exposure from using their gas or propane stoves.

[...]

its-summertime•21m ago
It seems they considered water boiling in their numbers, which makes this estimation very non-portable across countries (e.g. countries where gas hobs are used, but also electric kettles are used)
Spooky23•27m ago
I’ll be frank - I don’t buy this stuff because there are well funded agendas behind it. We find ourselves in an era where electrical utilities have shifted from widow & orphan dividend stocks to growth companies… and shockingly the environmental people are fully mobilized with gas everywhere.

Asthma is clearly correlated to urban areas with exposure to various pollutants. We’d see those same clusters in suburban populations with gas stoves if these indoor pollutants were elevating risk.

I live in New York. The utility in my region successfully lobbied to hike delivery rates for electricity by 40%. My spring electric bill is $300/mo, as much as my peak August or January utility bill a decade ago. 3-5 years ago, various foundations were bussing hundreds of protestors to lobby for climate change legislation that is essentially outlawing new natural gas service. They also prevented construction of pipelines to serve NYC and New England with additional capacity. All new construction must be electric only.

foco_tubi•11m ago
Observational evidence is confounded by numerous variables, to say that “urban centers have clusters of asthma and rural centers don’t” ignores all of the extant factors of the urban environment. Studies have found that gas stoves could play a role in development of childhood asthma. It may not scale to the magnitude of that seen in urban cores, with the addition of other sources of air pollution, but it’s weird to discount the studies entirely as a propaganda campaign by Con Ed.
jMyles•24m ago
I love my induction cooktop. I despise - in fact loathe - the touch interface, which becomes useless with the slightest spill of oil (and can thus be stuck on high until the interface is sufficiently wiped off and dried).

I have the Gasland IH77BFH. If someone has made a hack to modify this by adding physical dials, I'd be tickled.

6DM•18m ago
I didn’t see it in the article, but I wonder if this is still the case if people who properly vent before turning on their gas stoves and continue to vent for a minute after cooking is finished.
stevenkkim•15m ago
I feel like it should seem obvious gas stoves create unhealthy pollution in an indoor environment.

What is less obvious and what I would personally like to know is how much pollution remains if you have a hood above your gas stove that exhausts outdoors that is operating while cooking.

micromacrofoot•8m ago
some definitely does linger and most consumer kitchen hoods are not strong enough, you can get a pm2.5 meter and find out yourself... in my experience a couple hours

the craziest thing is no hood at all, if you cook once a day that stuff lingers all day unless you open a bunch of windows

gpm•14m ago
Along the same lines - replacing gas stoves with electric ones is effective for treating asthma:

xnx•11m ago
Cooking itself pollutes the air (e.g. oil droplets) so external ventilation is still essential.
stephbook•11m ago
I don't get it. Did the US never get electric stoves? They're over 100 years old tech at this point.

It's weird that noone here mentions there are electric stoves between gas and induction.

16m ago
Agreed - maybe not lots - but I got myself a HIS8055U three years ago specifically because it had knobs. No regrets there. I wish it had one larger burner, but completely night and day with traditional electric.
Zanfa•34m ago
This! The only electric (induction or otherwise) stovetops are either bottom of the barrel portable or top of the line commercial models. Everything in between is capacitive touch garbage.
tass•27m ago
I bought a relatively inexpensive induction range from LG specifically because it has knobs - a lot of the more expensive ones from other brands were capacitive touch.
mort96•33m ago
I hate it but I think the reason might be regulations? I have family who recently had to replace their stove setup, they used to have a combined oven + stovetop thing where dials on the front of the oven controlled the stovetop. They wanted the replacement to work the same way but there were no options, and when they asked, they were told it's no longer legal for the stovetop and the oven to be electrically connected in that way (or something along those lines).

No idea if it's true or if it was just an impressively creative salesperson.

But it sucks. I've accidentally burned cookware by having parts of the stovetop turn on intentionally. And sometimes, if my fingers are moist while cooking (imagine that!), the touch controls just go completely insane and I have to spend time drying my hands and the controls before I regain control over the stove.

IMO the new design with touch buttons is way more dangerous.

Hikikomori•31m ago
Still easy to manage, quick wipe with a paper towel, but rarely need to do even that.
gpm•29m ago
Yeah, so my (electric) stove has knobs, but my oven and microwave are both touch buttons and this has literally never been an issue.

Admittedly I have other complaints about the microwave controls (why is it so damn many button presses to vary the power output) but it's not because the buttons are hard to use.

ericpauley•31m ago
Am I missing something? A quick search for electric ranges on Home Depot shows simmerstats at every price range.

The harder one is induction, where there are lots of touch controls, but I don’t see this issue on traditional resistive stovetops.

(This is in the US of course)

beached_whale•23m ago
I've seen induction with dials for the stove. Ovens have had electronic buttons for decades though.
pornel•16m ago
Induction is the good one - it has instant response like gas.

Resistive electric stoves suck and deserve their reputation, but induction is the best of both worlds: high power, accurate control, and you don't waste half of the energy due to the flame's heat going around the pot.

But the touch-sensitive controls are infuriating indeed. Nothing about induction requires them, it's just a dumb design fad.

cassianoleal•10m ago
Induction is shit. Horrible stuff. Not nearly the same level of control and heat dissipation as gas. Much better than resistive, but about 10% as good as gas.

Where it has a clear advantage is in boiling speed when used at full power. I've ditched my electric kettle for a stovetop one. There's not a day I'm cooking that I don't somewhat regret having replaced the old and crappy gas stove.

Even with very thick cast iron pans, the hot spots are there at any power. It takes longer for the pans to heat up and the heat is never uniform.

For pots with thinner floors, I bought thick heat diffusers. Again, they help - but they just make everything less responsive and probably a lot less efficient as well. Not to mention they don't actually make the hot spots disappear either.

shimman•12m ago
Can literally do all these (except nabe, don't understand what's happening there) with a basic cast iron pan + induction stove top.

They may be different cooking tools but if one is ruining the quality of your life + possibly children, wouldn't you rather do it the safe way? Or are your habits more important than your health?

mint5•33m ago
“Whatever the harmful effects on my health are, that is a trade I make consciously”

Technically since it appears the effects are nebulous to you and if consciousness means informed then it seems a conscious decision is not possible

Hikikomori•33m ago
Induction is as good or better for everything except a wok.
jedberg•22m ago
They have wok adaptors for induction now.
lightedman•9m ago
There are actual induction units for woks now. They're large but they really get almost the whole wok really hot really fast! I'm assuming there are multiple induction loops inside the unit to be able to make that happen given how deep the wok must sit inside the unit.
lokar•31m ago
Induction is more precise with better control
atrettel•20m ago
And induction gets hot immediately. And it is easier to clean. And it is less likely to cause fires. It's just a better technology all around when compared to gas stoves. The only issue I personally have with it is that it is not compatible with all cookware.
cosmic_cheese•28m ago
Maybe it’s just because the gas stoves I’ve worked with are cheap, but I find them frustrating because their temperature ramps aren’t remotely linear, which can make finding exactly the right setting a pain.
foco_tubi•27m ago
Tradesmen typically are paid to offset the health effects of their profession, but you get benzene for free.
expedition32•9m ago
Professional kitchens have way better exhaust than your typical modern apartment.

If your kitchen is in your living room (and nowadays they all are) I would definitely switch to induction.

DANmode•26m ago
It’s not the flame/carcinogens that I’m most worried about personally, but instead the gas.

Oh, and I disagree with the fire being more precise than induction etc.

It’s just what you’re used to.

jghn•25m ago
> Nothing but an open flame gives me the kind of control I need to cook with the precision I do

Please explain how an induction cooktop doesn't give you the control and precision you need as compared to gas flame.

jedberg•24m ago
Many professional cooks who are building new kitchens are doing it with induction. Induction gives you even more precise control, especially since they can put more sensors on the cook surface since it doesn't get as hot.
lightedman•17m ago
"I'd wager anyone who opines otherwise in this thread barely cooks or doesn't cook in a serious fashion."

I started my taxable life almost 30 years ago in a Chinese kitchen. I'm literally a born-in-the-fire professional cook first and foremost out of any other thing in life I do. Induction rocks, I don't know what your skill issue is. I get pots and pans hotter, way faster than gas, and the temperature control is as fast as the cooking implement can shed the excess heat. That is as fine a degree of control as you can possibly get, the only better thing would be instantaneous temperature and that's basically a thermodynamic impossibility.

analog31•13m ago
I've cooked every day for 40 years. Before that, I learned to cook at home on an old fashioned electric stove with the coil elements.

Sure, the reaction time is slower. You learn to think ahead.

Nothing is optimal. The tenements that my kids lived in as students had gas stoves and zero ventilation. That couldn't have been a good idea.

Our latest stove is induction, made by LG, with control knobs. I love it. Best thing is it's easier to keep clean. I'm learning to be more reactive about turning the heat up and down, just because I can. Maybe I'll discover what I've been missing all these years.

Julia Child wrote that a home cook doesn't have to be a chef.

christoph•11m ago
Same. I feel I can give a very honest opinion on this as I insisted on a dual fuel hob when we refitted our kitchen 5 years or so ago.

The induction rings aren’t a patch on the gas ring for “proper” cooking. There’s simply no competition between them in that regard. Mad for anyone to suggest otherwise.

I’d wager you won’t find many commercial kitchens, even at the low/mid end not running some gas rings as well. I’d be amazed if any at the top-end were not using gas rings. The inductions are great for boiling some pasta or veg up fast though!

We have a massive outside venting hood overhead as well (which must have been required in UK building regs since at least the 90s?!?) so I really don’t care about indoor “pollution” lol.
