As a food it is very nourishing and restorative with such a complete range nutrients that it can, by itself, sustain life. This nutritional miracle is most evident in the animal kingdom where studies prove large and small grazing animals not only sustain themselves on young grasses but also improve their health. Wheatgrass contains raw chlorophyll, the blood of plants. Chlorophyll is condensed sunlight. Process of photosynthesis.
Green cells convert light to carbohydrates and oxygen.
All forms of life on land and sea may feed on each other, it's on plant eating animals. Ultimately all life depends on green plant life. Grass is one of the top three sources of chlorophyll. Algae and alfalfa. Mice, rats, rabbits, guinea pigs, cows, chickens, turkeys fed grasses in studies at the Univ.
