Coffee

You may have heard recently that California is now on the verge of requiring all coffee shops and manufacturers to include a warning on the beverage that it may cause cancer.

Nothing could be more ridiculous, and I will show you the reason, and back it up with many, many studies.

Roasting coffee beans creates Acrylamides, the substance in issue. Acrylamide might cause cancer at very high doses, but the amount that you’ll find in your food is relatively harmless. You’ve actually been unintentionally eating it for your whole life, because it’s in everything from coffee to roasted asparagus. When the media world exploded about the acrylamide in french fries last year, Professor of the Public Understanding of Risk at University of Cambridge David Spiegelhalter said: “Adults with the highest consumption of acrylamide could consume 160 times as much and still only be at a level that toxicologists think unlikely to cause increased tumors in mice.”

“…overall evidence suggests no association of coffee intake with cancers of the stomach, pancreas, lung, breast, ovary, and prostate.”

“Findings from this meta-analysis may support the hypothesis that coffee consumption is associated with decreased risk of postmenopausal breast cancer.”

“The clinical and experimental findings demonstrate various anticancer properties of caffeine and caffeic acid against both ER(+) and ER(-) breast cancer that may sensitize tumor cells to tamoxifen and reduce breast cancer growth.”

“In conclusion, dietary acrylamide intake was not associated with the risk of breast cancer in this population-based prospective cohort study of Japanese women.”

“there is no evidence to support a harmful effect of coffee consumption on prostate cancer risk.”
