Among the foods highest in fiber (47.5 g per 100 g). Its fiber is made up mainly of mucilages and alginic acid, a compound able to join heavy metal contaminants in various toxic and radioactive substances that are within us, forming alginates and thus facilitating their elimination.
The cochayuyo are among the foods with higher content of calcium (1160 mg per 100 g) iron (30 milligrams per 100 grams), magnesium and manganese, of course, with values well above 100 grams of food such as milk (125 milligrams of calcium per 100 g), lentils (7 milligrams of iron per 100g) or chicken liver (7, 9 milligrams of iron per 100 g).
Their intake of proteins is also noteworthy, being higher by 100 Ga our traditional cereals such as maize, wheat and rice. It contains all the essential amino in respectable quantities, such as 47% of its total protein.
Other nutrients that deserve special attention of its membership are phosphorus the zinc, the sodium, the potassium, the folic acid and vitamin E.
