A 100-gram portion of hulled hemp seeds supplies 586 calories. They contain 5% water, 5% carbohydrates, 49% total fat, and 31% protein. Hemp seeds are notable in providing 64% of the Daily Value (DV) of protein per 100-gram serving. Hemp seeds are a rich source of dietary fiber (20% DV), B vitamins, and the dietary minerals manganese (362% DV), phosphorus (236% DV), magnesium (197% DV), zinc (104% DV), and iron (61% DV). About 73% of the energy in hempseed is in the form of fats and essential fatty acids, mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.
While hemp seeds are grown in many parts of the world, its major producers include Canada, France, and China. Hemp has been prohibited from cultivation in the United States since about 1950. Despite its value, the U.S. government doesn't recognize the differences between industrial hemp and marijuana. In fact, the U.S. Drug Enforcement Agency, or DEA, classifies all varieties of Cannabis as marijuana, making industrial hemp just as illegal regardless of its use.
In the Australian states of Tasmania, Victoria, Queensland, Western Australia, New South Wales, and most recently, South Australia, the state governments have issued licences to grow hemp for industrial use. The first to initiate modern research into the potential of cannabis was the state of Tasmania, which pioneered the licensing of hemp during the early 1990s. The state of Victoria was an early adopter in 1998, and has reissued the regulation in 2008.
One of the most important hemp seed benefits is its high quantity of proteins. Moreover, there are a range of vitamins and minerals in hemp seeds, besides omega 3 and omega 6 essential fatty acids. Essential fatty acids are not synthesized by the human body naturally, and this is what makes hemp seeds an excellent food source of essential fatty acids. If you want to keep your heart healthy, you should try and consume a lot of hemp seeds, as they are rich in essential fatty acids. You can reduce the chances of a fatal cardiac arrhythmia or a heart attack if you substitute saturated fats with foods like hemp seeds, as they contain healthy fats. Moreover, it produces phytosterols, which help in reducing the amount of cholesterol in the body, thereby removing fat buildup in the arteries.
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.
Author Paoli Ranalli in the book, Advances in Hemp Research, states that one of the major minerals that one can find in hemp seed is iron, an integral part of red blood cell construction in the human body. Iron deficiency can result in anemia, so having a proper amount of iron intake from foods like hemp seed can help prevent anemia, which displays itself in symptoms like fatigue, headaches, muscle weakness, and a wide range of other symptoms. Iron also helps in reducing stress and anxiety.
Hemp seed food products are also considered more allergy-free than many other seeds. Hemp seeds contain the perfect balance of essential amino acids for sustaining good health. In addition, hemp seed oil contains necessary fatty acids, also known as good fats. Not only can hemp seeds provide valuable nutritional benefits to people, but they can also be used in pet foods and taste good too.
The seeds are sown with grain drills or other conventional seeding equipment to a depth of 1.27 to 2.54 cm. Greater seeding depths result in increased weed competition. Nitrogen should not be placed with the seed, but phosphate may be tolerated. The soil should have available 89 to 135 kg/ha of nitrogen, 46 kg/ha phosphorus, 67 kg/ha potassium, and 17 kg/ha sulfur. Organic fertilizers such as manure are one of the best methods of weed control.
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.
For profitable hemp farming, particularly deep, humus-rich, nutrient-rich soil with controlled water flow is preferable. Waterlogged acidic, compressed or extremely light (sandy) soils primarily affect the early development of plants. Steep and high altitudes of more than 400 m above sea level are best avoided. Hemp is relatively insensitive to cold temperatures and can withstand frost down to −5 °C. Seeds can germinate down to 1–3 °C. Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter. This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF. Roots can grow up to 3 feet into the soil and use water from deeper soil layers.
Hemp fiber has been used extensively throughout history, with production climaxing soon after being introduced to the New World. For centuries, items ranging from rope, to fabrics, to industrial materials were made from hemp fiber. Hemp was also commonly used to make sail canvas. The word "canvas" is derived from the word cannabis. Pure hemp has a texture similar to linen. Because of its versatility for use in a variety of products, today hemp is used in a number of consumer goods, including clothing, shoes, accessories, dog collars, and home wares. For clothing, in some instances, hemp is mixed with lyocell.
A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles. The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen and Volvo. For example, the Lotus Eco Elise and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).
The oil contained in the hemp seed is 75-80% polyunsaturated fatty acids (the good fats) and only 9-11% of the lesser desired saturated fatty acids. Hemp seed oil is reputed to be the most unsaturated oil derived from the plant kingdom. The essential fatty acids (EFAs) contained in hemp seed oil are deemed essential because our bodies do not naturally produce them. This means that they must be obtained from the food we eat.
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.
Despite this progress, hemp businesses in the US have had difficulties expanding as they have faced challenges in traditional marketing and sales approaches. According to a case study done by Forbes, hemp businesses and startups have had difficulty marketing and selling non-psychoactive hemp products, as some online advertising platforms and financial institutions do not distinguish between hemp and marijuana.
