No issues on "cookies are bad for you", although I'd take the position that the most dangerous ingredient is fructose, either as part of sucrose (which we humans instantly split into fructose and glucose using sucrase) or separately as HFC. Manufacturers tend to use HFC as it resists crystallization and so extends shelf life.

The issue with fructose is that we hominids react very strongly to it. It leads to de novo lipogenesis in the liver, and, from there, NAFLD. Rich Johnson has some interesting things to say about how this came to be: https://onlinelibrary.wiley.com/doi/full/10.1111/joim.12993

Agreed on the potential toxicity of acrylimide. But the danger is in the dose. Looking at countries with high per capita coffee consumption https://worldpopulationreview.com/country-rankings/coffee-consumption-by-country

and I don't see any particular correlation in cancer rates https://worldpopulationreview.com/country-rankings/cancer-rates-by-country

For instance, look at Finland, highest per capita coffee consumption but relatively low in cancer.

All that said, yes, cancer is a lot of different (mostly mitochondrial related) diseases all under one label, so there's a lot of noise potentially swamping any signal, but still, I haven't much changed my 500ml/day coffee habit.

Sorry to go on so long...
