18 Foods Research Links to Increased Cancer Risk

3. Processed meats

Processed meats are those that have been flavored or preserved by fermentation, curing, salting, smoking, or adding chemicals. Some examples include ham, bacon, sausages, hot dogs, salami, pepperoni, beef jerky, and deli meats. Some research suggests that these foods can increase cancer risk because of the nitrates and nitrites used as preservatives. For example, studies have found that nitrates and nitrites were positively associated with breast and prostate cancer risks and that increased consumption of processed meats may lead to a higher risk of colon cancer. Processed meats have also been associated with increased risks of lung cancer.
