It is said that coffee causes cancer because it contains acrylamide. When the human body ingests 2.6 micrograms to 16 micrograms of acrylamide per kilogram of body weight every day, there is a risk of cancer. According to this calculation, the daily acrylamide tolerance of a person weighing 55 kg is 143 micrograms. A cup of coffee 160 ml has an average acrylamide content of 0.45 micrograms, and at least 3 18 cups a day may cause cancer.
