You should check out this video, it’s very eye-opening when it comes to how microwaves work (only linking to YouTube because I couldn’t find a decent Invidious source): https://youtube.com/watch?v=UiS27feX8o0
It depends on your model of microwave.
Personally, my wife and I intentionally deprived ourselves of a microwave in the house because we recognized that it makes us more prone to heavily processed foods (we’re not crazy “5G/microwaves give you cancer”people or whatever). We just recognized that we like eating whole foods and having one on hand makes it tempting to start buying a lot of garbage foods.
Especially on a forum-style network dedicated to discussion 🙈
