They come in all different sizes, shapes and colours. The seed is an embryonic plant itself and the origin of nutrition. A plant goes to great lengths to produce each seed and fill it with high concentrations of vitamins, minerals, proteins, essential oils and dormant enzymes. If you’re looking for a high quality, nutritious and filling snack, seeds are tough to beat. A seed is life. It is a living food. It is impossible to eat a raw seed and not derive nutrition. In different seeds the seed embryo or the endosperm dominates and provides most of the nutrients. The storage proteins of the embryo and endosperm differ in their amino acid content and physical properties.
