This article is about the safety of sodium nitrate, a common preservative used in cured meat products. It explains how nitrates and nitrites serve an important bodily function and are found in vegetables as well as processed meats. The article also discusses the potential dangers of nitrosamines, which can be formed from sodium nitrate, and compare...
Sodium nitrate is a common preservative used in cured meat products, linked to heart disease and diabetes. The human body needs nitrates and nitrites which serve an important bodily function. Most of our nitrates come from vegetables.
85% of the nitrates in our diet come from vegetables, most notably celery, spinach and carrots. These provide the body with healthy carbs and fiber that help prevent conversion of nitrosamines into carcinogens.
