Everything is a carcinogen pretty much though.
Eat meat? Better boil or steam everything because any bit of char on meat is a carcinogen. Especially avoid all red meat and sandwiches in general.
Don’t heat potatoes or a lot of other vegetables too high either. They can produce acrylamide, another carcinogen that’s also found in tobacco smoke.
Never drink alcohol either because it’s a carcinogen.
Don’t fry anything. Causes cancer.
Peanuts and peanut butter are laced with aflatoxins that are carcinogenic.
Literally everyone gets cancer several times in life. Most of the time your body kills it off. It’s only when that fails that we catch it. The longer we live and the more we minimize other factors, the bigger cancer will become as a cause of death.
Life is too short to worry about that shit. Cut out most of the processed crap and cook and eat whole unprocessed foods mostly and you’ll be fine.
