The gamma-linoleic acid content of hemp seed works as a hormone regulator for the thyroid and pancreas, and it can reduce many of the symptoms that come from a hormonal imbalance, including severe menopausal symptoms, mood swings, depression, and anxiety. It also can help regulate the hormones that affect weight gain and hunger. Overall, by re-balancing your hormones, your body will work at its optimal and ideal level.
Once open, put the package or its contents in an airtight container and refrigerate or freeze it to extend the shelf life. Once opened, you can expect a bag of hemp seeds to last for about a year in the refrigerator or freezer. If you keep a package in your pantry, however, that shelf life will be more like 3 to 4 months. If you give your bag of seeds a sniff and they smell rancid, toss them.
Hemp protein is also a complete source of all 20 known amino acids including the 9 essential amino acids (EAAs) which our bodies cannot produce. Approximately 65% of the protein in hemp seed is made up of the globulin protein Edestin, and is found only in hemp seed. Edestin aids digestion, is relatively phosphorus-free and considered the backbone of the cell's DNA. The other one third of hemp seed protein is Albumin, another high quality globulin protein similar to that found in egg whites. Hemp protein is free of the tryspin inhibitors which block protein absorption and free of oligosaccharides found in soy, which cause stomach upset and gas.
Although hemp and marijuana are members of the same species, Cannabis sativa, they're in effect completely different plants. There are about a dozen varieties of hemp plants that are grown for food, and all of them contain about 0.001 percent Tetrahydrocannabinol, or THC, the main psychoactive ingredient in marijuana. This means you can eat as much hemp as you want and you'll never have to worry about getting high or failing a drug test. Although certain states have begun to legalize the cultivation of industrial hemp in the last couple of years, the hemp seeds you can find at your grocery or health food store were likely grown in Canada or China.
From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3,000 square kilometres (1,200 sq mi) in 1970). The main production areas were in Ukraine, the Kursk and Orel regions of Russia, and near the Polish border. Since its inception in 1931, the Hemp Breeding Department at the Institute of Bast Crops in Hlukhiv (Glukhov), Ukraine, has been one of the world's largest centers for developing new hemp varieties, focusing on improving fiber quality, per-hectare yields, and low THC content.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age." "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."
Hemp is possibly one of the earliest plants to be cultivated. An archeological site in the Oki Islands near Japan contained cannabis achenes from about 8000 BC, probably signifying use of the plant. Hemp use archaeologically dates back to the Neolithic Age in China, with hemp fiber imprints found on Yangshao culture pottery dating from the 5th millennium BC. The Chinese later used hemp to make clothes, shoes, ropes, and an early form of paper. The classical Greek historian Herodotus (ca. 480 BC) reported that the inhabitants of Scythia would often inhale the vapors of hemp-seed smoke, both as ritual and for their own pleasurable recreation.
Queensland has allowed industrial production under licence since 2002, where the issuance is controlled under the Drugs Misuse Act 1986. Western Australia enabled the cultivation, harvest and processing of hemp under its Industrial Hemp Act 2004, New South Wales now issues licences under a law, the Hemp Industry Regulations Act 2008 (No 58), that came into effect as of 6 November 2008. Most recently, South Australia legalized industrial hemp under South Australia’s Industrial Hemp Act 2017, which commenced on 12 November 2017.
Hemp seeds have long been prized as a high-quality source of plant-based protein and omega fatty acids. A single serving of hemp seeds, about two heaping tablespoons, provides 10 grams of protein and 10 grams of omegas. Hemp also packs in all nine essential amino acids, which we need to get through diet since our bodies don't produce them naturally. Hemp seed oil, which is the oil derived from pressed hemp seeds, contains the most essential fatty acids of any nut or seed oil. Of the three main hemp products on the market—seeds, oil, and protein powder—hemp seeds will provide the broadest spectrum of nutritional benefits per serving.
Hemp seeds are one of the best sources of plant-based protein and GLA and have a wide variety of health benefits, including their ability to improve heart health, stimulate digestion, build muscle mass, eliminate insomnia, treat anemia, and aid in weight loss. They also help to stimulate metabolic activity, boost the immune system, reduce symptoms of menopause and menstruation, improve skin and hair health, and build stronger bones.
