1. Processed meat
Processed meats like bacon, hot dogs, and lunch meat offer a double-punch of disease risk. The saturated fat tends to cause inflammation, while the preservative nitrates and nitrites are directly linked to cancer.
High cooking temperatures associated with these meats also create byproducts that can result in swollen and painful joints, and when you get those tasty char marks on food, a carcinogenic chemical called acrylamide develops. Some studies indicate that regularly consuming charred meat can increase your risk of pancreatic cancer by a gut-churning 60%.
