Nitrates in cured meats, comparable to bacon, scorching canines and chilly cuts, have lengthy had a foul rap, however extra lately there’s been quite a lot of speak concerning the well being advantages of nitrates in beets and different greens. Complicated? Sure. However we’ll straighten all of it out for you.

What Are Nitrates?
Nitrates are compounds made up of nitrogen and oxygen. Most come from vegetation, comparable to leafy greens, beets and celery. They’re additionally added to processed meats—within the type of sodium nitrate or sodium nitrite—as a preservative, or to boost taste, shade and texture.
Potential Advantages of Nitrates
After we eat nitrates from vegetation, our physique converts them to nitric oxide, which has been proven to have a number of advantages, comparable to regulating blood strain and bettering circulation. This, in flip, can increase each coronary heart well being and athletic efficiency. For instance, a 2021 examine discovered that lively grownup males who acquired nitrates derived from beet juice elevated their muscle energy output. One other trial confirmed that consuming at the least 60 milligrams of nitrates from greens every day (that is about what you get from 1 cup of uncooked inexperienced leafy greens) could considerably cut back the chance for coronary heart illness. As well as, nitrate-rich vegetation present “many different health-promoting vitamins, together with antioxidants and potential anti-inflammatory compounds,” explains New York Metropolis culinary nutritionist Jackie Newgent, RDN, CDN.
Potential Downside of Nitrates
So why are they an excellent factor in beets however not bacon? In processed-meat merchandise, nitrates can mix with the proteins’ amino acids and kind nitrosamines, which have been related to an elevated danger of sure cancers. A World Well being Group report discovered that every 50-gram portion of processed meats an individual ate per day (that is about 5 slices of bacon) upped their odds of colorectal most cancers by 18%. The proof was sturdy sufficient that WHO classifies these meals as a Group 1 carcinogen—the identical designation as tobacco.
Consuming loads of vitamin C and different antioxidant-rich meals might help block the manufacturing of nitrosamines—and offset the possibly adverse results of processed meats, explains Melina Jampolis, M.D., an internist and board-certified vitamin specialist in Los Angeles. Actually, producers are beginning to add vitamin C to cured meats for simply this motive. Excessive warmth may contribute to nitrosamine formation, so Jampolis recommends cooking processed meats at decrease temperatures. (For instance, microwaving bacon could also be higher than frying it, in line with some analysis.) However the very best guess is to easily cut back the quantity of them you eat. And that goes for meals labeled “pure” or “nitrate-free” too. Research present that the conversion of nitrates to nitrosamines can happen no matter whether or not they’re natural or artificial—in order that “pure” scorching canine might not be any more healthy for you. As for merchandise boasting “no added nitrates,” Jampolis says these are sometimes made with celery powder, which accommodates naturally occurring nitrates and might nonetheless produce nitrosamines (though it’s not thought-about an added nitrate).
The Backside Line
Nitrates from vegetation and people added to meat behave very otherwise within the physique. Growing your consumption of nitrate-rich veggies could cut back blood strain and enhance athletic efficiency. However it’s greatest to restrict your consumption of processed meats (even “pure” and “nitrate-free” merchandise), that are related to an elevated danger of most cancers.
