Spinach turned out to be not only tasty but useful as well as it contains nitrates, which can be the source of our energy. As well as other vegetables with green leaves, spinach is capable of increasing the energy effectiveness of the human cells. The matter is that scientists began to relate spinach to the group of products that are called super food, first it was mentioned about it in 1930. Then a new animation character, Popeye by name, appeared on television, he ate spinach without fail before every fight with the rival. Initially the key spinach feature was high content of iron but now it is proved that these green leaves are useful exactly for the nitrates, which actually increase power level in the cells of the human organism. Particularly experience has shown that a cupful of spinach during daily food intake allows our cells to work more effectively than ever before. If you take 300 grams of such a plant, it will make the level of oxygen, which is used by the muscles during exercise, 5% lower. This effect will last for three days after you visit a gym. The researches from Karolinska Institute, which is located in Stockholm, have come to the decision that just the nitrates of the mitochondrion, which can be found in spinach, allows cells to work more effectively.
