How Ultra-Processed Foods Impact Your Health

6. Cancer and increased mortality rates

Diets high in ultra-processed food also lead to increased cancer incidence and mortality rates. Research shows that for every 10 percent increase in ultra-processed food, the overall incidence of cancer increases by two percent and ovarian cancer by an astounding 19 percent. A 10 percent increase also affected cancer mortality rates, leading to a six percent increase in mortality for all cancers, 16 percent for breast cancer, and 30 percent for ovarian cancer.

Researchers believe this may be because ultra-processed foods are nutritionally inferior and can contribute to other risk factors, like obesity. Some studies also show that exposure to additives and contaminants may contribute to cancer and cancer mortality.
