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).
