For decades, we have often rated nitrates as an ingredient that is toxic to human health. However, recently many scientists have cleared this compound.
Nitrate is the salt of nitric acid (NO3) It is contained in soil, water and plants and animals that absorb it from there. It is one of the nitrogen compounds and is used by plants and animals as a source of nitrogen. However, we need to make a clear distinction Nitrate and Nitrite (NO2).
According to nutritionist Kristin Gillespie: “Nitrate differs from nitrite in chemical structure. NO3 contains 3 oxygen compounds and NO2 contains only 2 oxygen compounds. Nitrates are stable and are not likely to harm the body. However, Bacteria and enzymes are capable of converting them into nitrites and are harmful“.
According to scientists, Nitrate can be converted to 2 types of nitrite (Nitric oxide or Nitrosamine).. When Nitric oxide is beneficial then Nitrosamine is harmful to health.
Many people often mistakenly believe that the common human source of nitrates is meat, but that is not the case. According to dietitian Barry Sears, The most common source of nitrates in our diet comes from green vegetables like spinach, beets and carrots … About 80% of the nitrates that the average person uses comes from vegetables.
Nitrates are also added to processed meats as a preservative to prevent food poisoning.
Nitrate in vegetables will be converted to beneficial nitrite when they come into contact with the bacteria in the mouth. These substances help in the production of nitric oxide which helps to lower blood pressure.
In addition, nitrates are also added to processed meats as a preservative to prevent food poisoning. Besides, Nitrates also help keep meat pink, not brown.
According to some nutrition experts, nitrates are used in most processed meat products such as ham, sausages, bacon … There, they are responsible for preserving the meat.
Natural nitrates, such as those found in vegetables, are believed to be safe and even beneficial for the health of consumers. Studies have also shown that natural nitrates can reduce the risk of cancer, reducing the risk of chronic diseases.
However, Nitrates found in foods such as processed meats can turn into nitrites when combined with stomach acids, potentially forming cancer-causing nitrosamines. In addition, when proteins and nitrates are combined at high temperatures, they can also form nitrosamines.
However, you should not be too concerned that consuming more processed meat will cause cancer. A study published on the BBC in 2019 found that the proportion of people who eat 50 grams of processed meat (three strips of bacon) per day with bowel cancer in the UK is not much higher than the average rate of disease. this nationwide.
Of course, to stay healthy, you shouldn’t overeat and overeat processed foods. A scientific diet is to avoid processed foods, vegetables and fruits, rich in fats and healthy proteins … When owning such a diet, sometimes you eat a little bacon also does not affect your health. Medical experts say you need to remember that a healthy, regular diet and exercise will contribute the most to our overall health.
