If you began to lead a healthy lifestyle, you probably began to consume more vegetables and fruits! So you inevitably come across reliable information and rumors about nitrates. Let's get together to understand what it is, how to determine their presence and how to get them out of food and the body.
What are nitrates, what are they eaten with and why do they appear in fruits and vegetables?
Nitrates are salts of nitric acid that plants need for development. But plants take more nitrate from the soil than they need. The nitrates unclaimed during the formation of vegetable proteins still remain in vegetables and fruits and, accordingly, they enter the body in pure form.
Some nitrates are excreted from the body, but the other part, when interacting with intestinal microflora, forms harmful chemical compounds - nitrites.
What is the danger of nitrates and nitrites?
- 1 The saturation of the body's cells with oxygen is deteriorating, as nitrites prevent hemoglobin from carrying oxygen.
- 2 Serious disruptions in metabolism occur.
- 3 Weakened immune system.
- 4 An imbalance occurs in the nervous system.
- 5 Reduced absorption of vitamins.
- 6 There are problems with the gastrointestinal tract, with the cardiovascular and respiratory system.
- 7 Formed nitrosamines, the strongest carcinogens.
Of course, you will not feel the negative effect of one strawberry with nitrates, but with regular intake of small doses, the harm is no less than with one-time high intoxication.
- According to the WHO, the maximum permissible daily intake of nitrates is 3.7 mg (5 mg in the spring) per 1 kg of body weight, and nitrite is 0.2 mg.

Portable Nitrate Testers
The device is not cheap, but it helps to determine the harm of vegetables directly on the market, without departing from the counter. You just need to stick it in a vegetable or fruit, and the content of nitrates will be displayed on the electronic display. Data on the rate of nitrates will not have to remember - they already exist in the base of the device.
With their help, you can check the vegetables only at home. You should cut the vegetable, attach a strip to it and wait for the result. If there is a lot of nitrates, the strip will confirm this with an intense indicator color.
