All unrefined foods have varying amounts of protein with varying amino acid profiles, including leafy green vegetables, tubers, grains, legumes, and nuts. All the essential and nonessential amino acids are present in these foods in amounts that meet or exceed your needs.
There are 20 amino acids which humans need to construct all the different proteins we need in our bodies. 12 of them are 'nonessential; they can be made in the body by conversion from another molecule or amino acid. However 8 are 'essential'; they cannot be made in the body and so must be provided in the diet if deficiency diseases are to be avoided. A first-class protein is one which contains all 8 essential amino acids (and may contain some of the nonessential ones too).
