Are the nitrites in cured ham a health risk?

Nitrites are preservatives and antimicrobial agents; they also help maintain the product’s color and flavor. After more than 50 years of studies, the debate about possible adverse effects continues. Nitrates have been implicated as a cause of a variety of illnesses including pulmonary disorders and cancer. In view of the uncertainty about health risks, it’s probably a good idea to eat products with nitrites (including hot dogs and luncheon meats) in moderation and perhaps to avoid them altogether during pregnancy.
