Spice Consumption and Increased Risk of Cancer?
My friend conceded what I've generally read about spices and health -- that certain spices have health benefits and help fight cancer -- but warned that excessive consumption of "some spices" can actually increase risk of cancer. Is this true? I tried finding info online, but whenever I search the terms "spice" and "cancer" I only found lists of the health benefits of spices. Has anyone heard of a danger associated with excessive consumption of certain spices?
