What does nitrite do in a meat product? What are the restrictions on the use of the word 'natural' on the food label of a meat product where nitrite has been removed? Can I use the word 'natural' in my ingredients declaration?
For further Information see our FAQ on nitrites and nitrates 1 Nitrates are not permitted to be added directly to heat-treated meat products however, they may be present in some heat-treated meat products resulting from natural conversion of nitrites to nitrates in a low-acid environment.

Nitrate and nitrite ions are used as food additives to inhibit the growth of microorganisms in cured and processed meats.
Vegetables contain significant quantities of nitrate and nitrite. Actually, the vast majority of consumed nitrate and nitrite comes from natural vegetables and fruits rather than food additives.
For years, the cancer risks of these two ions have been discussed, since they potentially convert into the carcinogenic nitrosamines. However, recently, these two ions have been considered essential nutrients which promote nitric oxide production and consequently help cardiovascular health. It seems that the role of these two ions in our diet is important now from a different point of view.

Limited capacity to produce nitric oxide is associated with heart disease, diabetes and erectile dysfunction.
Found in vegetables like beets, nitrites also help us form nitric oxide, which lowers blood pressure Credit: Getty. One way the body makes nitric oxide is from an amino acid a building block of protein called arginine. We also know that this may be particularly important in older people, since natural nitric oxide production via arginine tends to drop with ageing.
Nitrates in leafy greens are less likely to form cancer-causing nitrosamines and have plenty of health benefits Credit: Getty. So when most of the nitrates in our diets come from vegetables — and in turn encourage nitric oxide formation — they are probably good for us. But the report also noted that people of all age groups can exceed this ADI quite easily. Nitrite intakes are generally much lower one estimate of average intake in the UK being 1.
As always, dose makes the poison, and levels of grams mg of nitrate can be acutely toxic, causing changes in haemoglobin that present as a blueish tinge to lips and skin. The upshot? If you want to eat the right kinds of nitrates and nitrites and avoid the potentially carcinogenic ones, then eat a widely varied diet with at least five servings a day of fruit and vegetables, and avoid nibbling on processed meats too often.
