Burnt Toast

Factual Questions
1

Hi everyone,
My girlfreind and I got into a debate as to whether or not (according to her) the black burnt part on toast is cancerous. I’ve always been told that it’s innocuous, and that, if anything, it’ll make… your bowels easier to loosen.
Granted, neither of us has any kind of infomation from any kind of authority, rather “I’ve been told” kind of info. So nnow I’m turning to my great encyclopedia of answers, you guys.

Thanks for any clarifaction!

Charred foods - Suspected Carcinogen - Stomach, colon and bladder cancer - Barbeque grilled food. Burnt toast, shish kebabs. - Only eat grilled foods, avoid charred or heat blackened foods.
