The protein contained in potatoes has 18 kinds of amino acids, including amino acids that cannot be synthesized by the human body. Of course, in addition to protein, there are also various vitamins, inorganic salts and trace elements.

After talking about the nutritional content of potatoes, let’s go back to overnight potatoes. The above mentioned nitrite, which has strong oxidizing properties and will accelerate the aging of the human body.

Nitrite can also react with hemoglobin in the human body, reducing its activity. The most important thing is that it can also cause cancer and is a strong carcinogen.
