With 78% essential fats hemp oil greatly exceeds soy oil at 40%, canola oil at 30%, olive oil at 10% and other oils. Omega 3 and Omega 6 essential fats may reduce cholesterol, blood pressure, coronary heart disease and stroke. The 3:1 ratio of Omega 6 to Omega 3 EFA's in hemp oil is thought to be the best in nature for promoting cellular health. Hemp oil contains more "Omega 3" EFA components (19%) than are found in any fish and in most fish-oil supplements.
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 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.
Two tablespoons of hemp seed serve up 90 calories and six grams of fat. Watching what you eat? I say, "Keep sprinkling!" That two-tablespoon serving size offers two grams of fiber, five grams of protein, 300 mg of potassium, 15 percent of your vitamin-A requirement and 25 percent of your daily iron needs. It’s hard to find another food that nutrient-dense.
Hemp rope was used in the age of sailing ships, though the rope had to be protected by tarring, since hemp rope has a propensity for breaking from rot, as the capillary effect of the rope-woven fibers tended to hold liquid at the interior, while seeming dry from the outside. Tarring was a labor-intensive process, and earned sailors the nickname "Jack Tar". Hemp rope was phased out when manila rope, which does not require tarring, became widely available. Manila is sometimes referred to as Manila hemp, but is not related to hemp; it is abacá, a species of banana.
Hemp plants are cultivated for industrial use and harvested for their fibers, seeds, oils, and meal. Industrial hemp seeds are available in different forms. They can be sterilized, toasted, roasted, or cracked. Hemp can be pressed into oil or hulled into meal. Hemp thrives nearly anywhere, tolerating a variety of growing conditions. It's rarely affected by pests or disease, making hemp quite hardy. In fact, the plant provides numerous benefits.
Furthermore, hemp seed has a final unique characteristic. Gamma-linoleic acid, commonly known as GLA, is a rare form of omega-6 fatty acid that can be found in very few edible sources, but it can have amazingly beneficial effects on your health. It has been connected to improving a number of cardiovascular conditions, and it helps to lower negative cholesterol while increasing the presence of beneficial cholesterol. Overall, this seed is a powerful weapon against damage to your heart.
The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti. In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill. Designed by Modece Architects, who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials. The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.
Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use, while C. sativa subsp. indica generally has poor fiber quality and female buds from this variety are primarily used for recreational and medicinal purposes. The major differences between the two types of plants are the appearance, and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes, although they can also be distinguished genetically. Oilseed and fiber varieties of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, hemp contains below 0.3% THC, while cultivars of Cannabis grown for medicinal or recreational use can contain anywhere from 2% to over 20%.
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.
There are many long-term health benefits that can be experienced. Hemp Seed is one of the best balanced sources of Omega 3 and Omega 6 essential fatty acids. Hemp Seed contains only small amounts of saturated and mono-unsaturated fats which can be easily converted to energy. Hemp Seed is also an unsurpassed source of the whole spectrum of required proteins, it promotes vigorous cellular development with diverse health benefits:
In 2017, the cultivated area for hemp in the Prairie provinces include Saskatchewan with more than 56,000 acres (23,000 ha), Alberta with 45,000 acres (18,000 ha), and Manitoba with 30,000 acres (12,000 ha). Canadian hemp is cultivated mostly for its food value as hulled hemp seeds, hemp oils, and hemp protein powders, with only a small fraction devoted to production of hemp fiber used for construction and insulation.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield, etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.
Most health organizations agree that the human body needs a 3 or 4:1 balance of omega 6 over omega 3. Hemp seed is the only seed where this ideal balance occurs. It does not occur in flax, almond, walnut, soybean or olive oil. Daily use of flax seed can lead to dangerous imbalances since flax seed oil has a balance of 1:4 instead of a healthy 4:1 omega-6 over omega-3.
