What is Nitrate do to our healthy? Is it harmful to us? Well, after reading this article, you will get a know. As nitrate in food, WHO suggests maximum daily intake of nitrates to be maximum 3.7mg/kg per body weight. So it is quite useful to monitor our intake level every day? But how, you can buy organic food or you can use Nitrate Tester to detect the level of nitrate inside the fruit and vegetales.
Nitrates occur naturally in some foods and are added to others to prevent them from going rancid or growing dangerous bacteria. While processed meat is commonly considered the No. 1 source of nitrates in the American diet, vegetables actually contain much higher levels of nitrate. There is no firm consensus on the health effects of dietary nitrates.
Nitrate, short for sodium nitrate, is a form of salt that has been used for thousands of years as a meat preservative, according to the University of Wisconsin Meat Laboratory. Because nitrate is able to inhibit the growth of dangerous bacteria, it is are classified by the U.S. Department of Agriculture as a preservative that can safely improve meat quality. Nitrates occur in natural sources such as vegetables, which is where they are sometimes extracted for use in meat products. However, there is no difference between the natural nitrates extracted from vegetables and purified nitrates that are also used in meat products.
According to Jeff J. Sindelar, Ph.D., extension meat specialist at the University of Wisconsin Meat Laboratory, about 80 percent of the nitrates you eat come from vegetable sources. Cured meat products, on the other hand, only account for 5 percent of total nitrate consumption. Because nitrates in soil are taken up by plants as they grow, leafy vegetables are particularly high in nitrates. Sindelar notes that most water is another source of nitrates, whose concentrations are also higher than that of processed meats.
On NutritionFacts.org, Michael Greger, M.D., reports on the top 10 vegetables with the highest concentrations of nitrates. Per 100 grams, beets contain 110 milligrams of nitrates; Swiss chard, 151; oak leaf lettuce, 155; beet greens, 177; basil, 183; spring greens, 188; butter leaf lettuce, 200; cilantro, 247; rhubarb, 281; and arugula, 480. According to Sindelar at the University of Wisconsin Meat Laboratory, the levels of nitrate in cured meats at the time of purchase are between .00002 percent and .004 percent. Therefore, 100 grams of cured meat would contain somewhere between 20 and 400 milligrams.
According to Martha Grogan, M.D., a cardiologist for Mayo Clinic, the sodium nitrate added to cured meats can harm your heart and increase your chance for heart disease and diabetes. However, Greger claims that the natural nitrates in vegetables can protect against heart disease, and Sindelar reports that the USDA and the U.S. Food and Drug Administration have deemed nitrates safe for use in food. In the end, nitrates are found in many foods and have been studied for their safety. However, it’s best to limit your consumption of processed meat because of the saturated fat and sodium it contains.
