Although we have seen no reports that the mature seeds of this plant are eaten, research has shown that they are a potential nutritious food for humans. They contain around 48% carbohydrate, 8.7% protein and 17.2% fats, plus a good range of minerals, though rather high in sodium. Antinutritional compounds such as tannins, saponins and oxalates are present, but in lower concentrations than in many commonly eaten foods. The sodium to potassium ratio is rather high and could lead to heart problems in later life if the seed becomes a major part of the diet - though eating the seeds with foods rich in potassium and low in sodium would restore a balance[
