Nitrates are salts of nitric acid. They are in each living organism therefore their presence at a human body is absolutely natural and doesn't bear any harm. But the excess of such substances is hazardous to health. Generally nitrates come to an organism from plant products, first of all, from vegetables. Therefore it is important to know how to distinguish useful vegetables from nitrate.
How to define naturalness of vegetables
First of all, it is necessary to keep track of seasonality. If the season, for example, of tomatoes, didn't come yet, and you see them on counters, so they imported. And to increase their period of storage, add nitrates to them. Learn about duration of harvest seasons of your country and don't give themselves to deceive.
Chemicals are added to vegetables to keep their appearance. Therefore if products look unnaturally faultless, fresh and strong, most likely, they won't bring you benefit.
Remember that midges and flies attracts only aroma of natural products therefore they completely ignore nitrate.
How not to be mistaken when choosing vegetables
When choosing tomatoes pay attention to their color. If at them there is an orange shade, so they were grown up with use of fertilizers. Then taste tomato to the touch. Press a finger: if the skin didn't burst and on it there was a dent from a finger, most likely, the product is full of nitrates.
Sometimes tomatoes are on sale directly on branches. Khimikatny tomatoes remain beautiful and fresh, they don't come off a branch even if begin to decay inside.
When choosing cucumbers run a hand over their surface. The soft, thin, easily erased thorns speak about naturalness of a product. Rough thorns and a dark green thin skin mean that cucumbers grew on a nitrate plantation. If there is no smell, you shouldn't buy cucumbers also. Journalists made a special experiment during which it became clear that the majority of cucumbers in the modern market and in supermarkets have no smell, so and taste. When choosing carrots pay attention to color. Natural completely orange, it is deprived of green and yellow impregnations. When choosing cabbage don't think that black dots and spots on it demonstrate lack of nitrates. On the contrary, dark stains on leaves is a fungus which appears on nitrate vegetables. Probe a head of cabbage. Leaves natural usually dense. Cabbage stump has to have not thick basis of leaves. The potato tubers which are grown up without addition of chemicals are also distinguished on appearance and to the touch. Potatoes with green spots say that tubers too long were in the sun. These spots – sign of presence of the poisonous toxin corned beef produced in plants and person very hazardous to health even in small doses. Natural potato has to be dense and elastic. The tubers containing a large amount of pesticides and nitrates look smooth and equal, and to the touch they are quite soft. When pressing on potatoes a nail you have to hear a crunch. If the nail enters a tuber without sound, so such potatoes were grown up on mineral and nitrogen fertilizers.
