Fresh raw tomato juice is rich in sodium, potassium, calcium and magnesium. It can take its rightful place among therapeutic and preventive nutrition. All varieties of tomatoes are equally healthy, but only in their raw form! Did you know that heat treatment turns tomatoes into poison?
The fact is that raw tomatoes contain a fairly high percentage of citric and malic acids, as well as a little oxalic acid. These acids are useful, but only until they are boiled. High temperature converts organic acids into inorganic acids, which are harmful to the body. So canned tomatoes and tomato juice from a can are, of course, tasty products, but not dietary at all.
Doctors recommend consuming them in moderation, replacing them with fresh ones whenever possible. The harmful effects of cooked tomatoes on the body do not appear immediately. And over time, canned tomatoes and tomato juice can even lead to the formation of stones in the bladder and kidneys.
