Coffee is in the news again thanks to California requiring a warning label.
This decision is apparently due to concerns with acrylamide – one of the chemicals present in roasted coffee beans, as well as fries and burnt toast. Acrylamide in high amounts has been shown to cause cancer in mice.
Coffee companies argue that the level of acrylamide in coffee isn’t enough to cause harm, and that there isn’t proof of harm in human studies. Proponents also argue that coffee has been shown to have many beneficial effects as well, including lowering risk of heart disease, type 2 diabetes, and early death.
Here’s an article about the new warning, and a link to a meta analysis of coffee’s effect on mortality for a wide ranging number of health conditions, showing when coffee could be harmful and when it could be beneficial, so that you can make up your own mind.
