Read More »Nitrates and nitrites are compounds that occur naturally in the human body and some foods, such as vegetables. Manufacturers also add them to processed foods, such as bacon, to preserve them and make them last longer. In some forms, nitrates and nitrites can be hazardous. However, they may also have health benefits. This article reviews nitrates and nitrites in the diet. What are nitrates and nitrites? Nitrates and nitrites are two different types of compound. Nitrates (NO3) consist of one nitrogen atom and three oxygen atoms. Nitrites (NO2) consist of one nitrogen atom and two oxygen atoms. Nitrates are relatively inert, which means they’re stable and unlikely to change and cause harm. However, bacteria in the mouth or enzymes in the body can convert them into nitrites, and these may be harmful. In turn, nitrites can either turn into: nitric oxide, which is beneficial for the body nitrosamines, which can be harmful There’s more information about these below. Manufacturers add nitrites to meat to preserve them. They’re the reason why cured meat is pink or red. In meat, nitrites turn into nitric oxide. This reacts with proteins in the meat, changing its color and helping preserve it. ( 1 ). Without nitrites and other additives, the meat would turn brown quickly. Summary Nitrates and nitrites are compounds consisting of nitrogen and oxygen atoms. Nitrates can turn into nitrites, which can then form either nitric oxide (good) or nitrosamines (bad). Where nitrates and nitrites are found Food producers often add nitrates and nitrites to processed meats, such as bacon, ham, sausages, and hot dogs. These added compounds help to: prevent the growth of harmful bacteria

Read More »Can nitrates fuel physical performance? Studies suggest that nitrates can enhance physical performance, especially during high intensity endurance exercise. Some people often use beetroot or beetroot juice for this purpose, because they contain high levels of nitrates. The reason for this improvement in physical performance may be due to nitrates increasing the efficiency of mitochondria. Mitochondria are the parts of cells that produce energy ( 21 ). A few studies have shown that beetroot can reduce the oxygen cost of exercise by 5.4%, increase time to exhaustion when running by 15%, and improve sprinting performance by 4% ( 22 , 23 , 24 ). Summary Studies suggest that dietary nitrates and nitrites can enhance physical performance, especially during high intensity endurance exercise. Risks of nitrates and nitrites Nitrates and nitrites are essential compounds, but they can become hazardous if they form nitrosamines. Nitrosamines can form if you cook nitrates or nitrites at high heat. (25). There are different types of nitrosamines, and many can increase the risk for cancer. (26). Nitrosamines are some of the main carcinogens in tobacco smoke, for example. Bacon, hot dogs, and processed meat can contain high levels of both sodium nitrite. They’re also high in protein, which is made up of amino acids. On exposure to high heat, this combination creates the perfect conditions for nitrosamines to form ( 27 ). Cooking vegetables, however, is less likely to produce nitrosamines. People rarely cook vegetables at very high heat, and they don’t contain large amounts of protein. Summary When nitrites and amino acids are present, carcinogenic compounds called nitrosamines can form during cooking with high heat. How to minimize nitrosamine exposure Manufacturers have to limit the amount of nitrites they use in processed meats by law, because of the dangers that nitrosamines pose. They also have to add vitamin C, which inhibits nitrosamine formation ( 28 ). The processed meat that you eat today contains less nitrite than it did a few decades ago. You can reduce your risk of nitrosamine exposure by making wise choices when shopping for processed meats, such as bacon. Some outlets sell quality bacon that’s nitrate-free. The ingredients should show that the bacon doesn’t have high levels of additives that contain nitrates. You should check the labels for: sodium nitrate (E251)
