By law, since we sell to California, we have to include this warning on specific products, ever since Prop 65 was passed.
Click here to read about the prop 65 bill.
In Prop 65, acrylamide is labeled as a cancer causing agent that must be labeled as such in all restaurants and stores that sell products that contain it.
Acrylamide is produced during the roasting process in coffee beans, or the baking process of breads and cakes, or the cooking process of just about any starchy food. Even Starbucks has to post this message.
The Office of Environmental Health Hazard Assessment Acrylamide fact sheet states:
"In 2002, Swedish researchers discovered that acrylamide forms during the baking, frying, or roasting of certain kinds of foods, particularly starchy foods. Acrylamide is not added to foods. It is a contaminant that forms during the baking, frying or roasting of certain plant-based foods. Boiling and steaming foods does not create acrylamide. French fries, potato chips, other fried and baked snack foods, roasted asparagus, canned sweet potatoes and pumpkin, canned black olives, roasted nuts, coffee, roasted grain-based coffee substitutes, prune juice, breakfast cereals, crackers, cookies, bread crusts, and toast all contain varying levels of acrylamide."
Fortunately, coffee is pretty much as safe as can be when you factor in the massive amount of antioxidants in coffee (especially if you add grass fed butter).
This is also why our Bulletproof Diet advocates cooking temperatures of 250 degrees fahrenheit / 121 degrees celsius, or lower, to reduce the creation of acrylamide and other harmful byproducts of high temperature cooking.
