The history of hemp seeds dates back to at least 5000bc, where it's first recorded use was by the ancient Chinese. If there ever was an "ancient Chinese secret", then they must've been talking about hemp.
Hemp food contain 35% carbohydrates, 30% fat, 35% fiber, calcium, magnesium, phosphorus, potassium, and vitamins A, B1, B2, B3, B6, C, D, and in particular vitamin E, and only about 8% saturated fat.
When judging how healthy a food is, the other factors you would want to look for are: it's protein content and it's essential fatty acid content.
Hemp seed contains 25%-31% protein, which is second only to soy. Soy contains about 35% protein. However - the hemp protein is more digestable. It contains the globular (edible) proteins albuumin and edistin, which are very similar to proteins that are made by the blood.
Protein is the building block of life. Proteins are broken down into amino-acids by the body, to be remade into the different types of protein that the body needs. Protein is also used to build hormones, antibodies, and the enzymes that regulate the chemical reactions that occur in your body.
Without protein, your body would not be able to build and repair cells and body tissue. Your muscles would not grow. Your blood would not clot correctly, so cuts and scrapes would not heal quickly.
Hemp foods contain all 20 known amino acids, including: Leucine, Lysine, Threoine, Phentyro, Valine, Meethcyst, Isoleucin, and Tryptophan, with higher amounts of each than many other sources of protein.
Hempseeds contain a higher amount of essential fatty acids than any other plant. Hemp nut is the only food item containing every essential fatty acid. Essential fatty acids are fatty acids that our body requires, but cannot make on its own. You have probably heard of the fatty acid omega3, which is commonly advertised to be in fish oil. Hemp also contains omega6 and super omega6, as well as linolenic acid and stearidonic acid. The ratio of Omega6 to Omega3 that is recommended is 3-to-1, the exact ratio that is found in hemp oil! Making hemp seed oil more ideal than fish oil or even flax oil.
