I’m a registered dietitian living and working in New York City. A lot of people ask me if deli meat is a healthy food to incorporate. I said that it is but I prefer for you to get organic. When you have organic there are no added nitrates.
Nitrates have been shown to be carcinogenic, that means that they can cause cancer.
When you go for organic they’re going to have some natural sources of nitrates like celery salt, but they won’t have additives so if you’re going to do deli meat, go for organic or skip the others.
