I remember seeing something about how carrageenan, a common ice cream thickener and emulsifier can cause cancer and is banned in the EU but not the USA. I was bummed when I checked my favorite brand and it actually had it as an ingredient.

Okay but this answers almost nothing, because cancer is not heart disease. Also, 'causing cancer' is a huge scam.

The top of the carcinogen scales is alcohol, tobacco, and red meat. Almost everything else falls into categories that 'might' cause cancer.
