Hemp hearts are the seeds of the hemp plant, Cannabis sativa.
They are from the same species as cannabis (marijuana) but a different variety.
Hemp hearts (or hemp seeds) are rich in healthy fats and essential fatty acids. They are also a great protein source (about 25% of the calories in hemp seeds come from protein). They contain all the essential amino acids, making them a complete protein source, and that is rare in the plant world. Only Quinoa has the same properties.
