Shelled hemp seeds are becoming a popular dietary supplement because of their high protein content and healthful fatty acids. Hemp seeds come from the same plants, Cannabis sativa or C. indica, that produce marijuana, although the plants are cultivated and processed differently so that hemp seeds contain very low levels of psychoactive cannabinols such as delta-9-tetrahydrocannabinol, or THC. Shelled hemp seeds are generally safe, but some people may experience some undesired side effects.
Further the protein content of the hemp seed is supposed to be very digestible. Many people noted their personal experience of finding that hemp seed protein did not cause bloating or gas, like some of their whey, or other protein shakes did. And, unlike soy which has super high amounts of phytic acid (that anti-nutrient that prevents us from absorbing minerals), hemp seed doesn't contain phytic acid. At the very least, this makes hemp seed a step up from soy.
In the UK, the Department for Environment, Food and Rural Affairs treats hemp as a purely non-food crop, but with proper licensing and proof of less than 0.2% THC concentration, hemp seeds can be imported for sowing or for sale as a food or food ingredient.[19] In the U.S., imported hemp can be used legally in food products and, as of 2000, was typically sold in health food stores or through mail order.[16]

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.[citation needed] 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.[citation needed] Seeds can germinate down to 1–3 °C.[citation needed] Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter.[citation needed] This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF.[citation needed] Roots can grow up to 3 feet into the soil and use water from deeper soil layers.

These seeds rank high in plant-based protein as it contains 25% of high-quality protein, which makes it superior to other plant-based superfoods like quinoa, flax, and chia seeds. Furthermore, it is composed of a large number of edible oils and a variety of essential fats in the body, including omega 3 and a rare form of omega-6 called GLA (gamma linoleic acid). As per the USDA National Nutrient Database, these small seeds contain high levels of zinc, magnesium, calcium, phosphorous, iron, and fiber. It also contains vitamin E, copper, manganese, and moderate levels of carbohydrates and fats.
Queensland has allowed industrial production under licence since 2002,[78] where the issuance is controlled under the Drugs Misuse Act 1986.[79] Western Australia enabled the cultivation, harvest and processing of hemp under its Industrial Hemp Act 2004[80], New South Wales now issues licences[81] under a law, the Hemp Industry Regulations Act 2008 (No 58), that came into effect as of 6 November 2008.[82] Most recently, South Australia legalized industrial hemp under South Australia’s Industrial Hemp Act 2017, which commenced on 12 November 2017.[83]

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.
Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6–14.0 tonnes of dry, retted stalks per hectare (1–5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha.[73][74] Only a part of that is bast fiber. Around one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha.[75] The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.[14]
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.[20] 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,[20] mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.[21]

Hemp seed is a wonderful source of dietary fiber, both insoluble and soluble, in a ratio of 4:1, says a report published in the Biosystems Engineering Journal by a team of researchers from Ankara University, Turkey. Insoluble fiber is best for bulking up the stool and easing the passage through the digestive tract, thereby reducing symptoms of both diarrhea and constipation. Soluble fiber, on the other hand, is responsible for slowing glucose absorption and increasing the digestive and gastric juices, which further ease the passing of bowels. Soluble fiber also stimulates bile juice, which reduces the amount of LDL cholesterol (bad cholesterol) in the body. Overall, the effects of these two types of fiber on the body can help you avoid a number of mild to serious health conditions.

Eating shelled hemp seeds, or hemp hearts, is as simple as sprinkling a spoonful or two into smoothies or on top of cereal, salads, or yogurt, says Kelly Saunderson of Manitoba Harvest Hemp Foods, the world's largest hemp foods manufacturer. People with gluten sensitivity can use hemp seeds as a substitute for breadcrumbs to coat chicken or fish. Just like you can blend almonds and water to make almond milk, you can do the same with hemp seeds for hemp seed milk, which you can use as an alternative to dairy milk in drinks and recipes. And because of its nutty flavor, hemp seeds make a great substitute for people with nut allergies—you can dry-toast them over low heat to bring out even more of that nuttiness.

Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated. (Roulac 1997; 149).
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.[citation needed]
Hemp has been grown for millennia in Asia and the Middle East for its fibre. Commercial production of hemp in the West took off in the eighteenth century, but was grown in the sixteenth century in eastern England.[148] Because of colonial and naval expansion of the era, economies needed large quantities of hemp for rope and oakum. In the early 1940s, world production of hemp fiber ranged from 250 000 to 350 000 metric tonnes, Russia was the biggest producer.[130]

Hemp was used extensively by the United States during World War II to make uniforms, canvas, and rope.[144] Much of the hemp used was cultivated in Kentucky and the Midwest. During World War II, the U.S. produced a short 1942 film, Hemp for Victory, promoting hemp as a necessary crop to win the war.[143] U.S. farmers participated in the campaign to increase U.S. hemp production to 36,000 acres in 1942.[145] This increase amounted to more than 20 times the production in 1941 before the war effort.[145]
Hemp Seeds are a perfect and natural blend of easily digested proteins, essential fats (Omega 3 & 6), Gamma Linolenic Acid (GLA), antioxidants, amino acids, fiber, iron, zinc, carotene, phospholipids, phytosterols, vitamin B1, vitamin B2, vitamin B6, vitamin D, vitamin E, chlorophyll, calcium, magnesium, sulfur, copper, potassium, phosphorus, and enzymes. All amino acids essential to optimum health are found in Hemp Seeds, including the rarely found Gamma Linolenic Acid (GLA). The 17+ grams of omega fats supplied by Hemp Seeds provides sufficient, continuous energy throughout your day. Many users also experience these health benefits:

The process to legalize hemp cultivation began in 2009, when Oregon began approving licenses for industrial hemp.[97] Then, in 2013, after the legalization of marijuana, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century.[98] After that, the federal government created a Hemp Farming Pilot Program as a part of the Agricultural Act of 2014.[99] This program allowed institutions of higher education and state agricultural departments to begin growing hemp without the consent of the Drug Enforcement Agency (DEA). Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[100] Hemp production in North Carolina resumed in 2017,[101] and in Washington State the same year.[102] By the end of 2017, at least 34 U.S. states had industrial hemp programs. In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.[103]

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.
In the early 1990s, industrial hemp agriculture in North America began with the Hemp Awareness Committee at the University of Manitoba. The Committee worked with the provincial government to get research and development assistance, and was able to obtain test plot permits from the Canadian government. Their efforts led to the legalization of industrial hemp (hemp with only minute amounts of tetrahydrocannabinol) in Canada and the first harvest in 1998.[85][86]
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.
Use of industrial hemp plant and its cultivation was commonplace until the 1900s, when it was associated with its genetic sibling a.k.a. Drug-Type Cannabis species (which contain higher levels of psychoactive THC). Influential groups misconstrued hemp as a dangerous "drug",[56] even though hemp is not a recreational drug and has the potential to be a sustainable and profitable crop for many farmers due to hemps medical, structural and dietary uses.[57][2]
One claim is that Hearst believed[dubious – discuss] that his extensive timber holdings were threatened by the invention of the decorticator which he feared would allow hemp to become a cheap substitute for the paper pulp used for newspaper.[126][129] Historical research indicates this fear was unfounded because improvements of the decorticators in the 1930s – machines that separated the fibers from the hemp stem – could not make hemp fiber a cheaper substitute for fibers from other sources. Further, decorticators did not perform satisfactorily in commercial production.[130][126]

One of the most important aspects of hemp seed is its high mineral content, including magnesium, which creates a very soothing and relaxing sensation throughout the body. Magnesium has various stimulating qualities on enzymes and hormones that induce sleep. According to a report published in the Journal of the American Geriatrics Society, Serotonin is released when magnesium is administered, and it travels to the brain, where it becomes converted to melatonin. Melatonin is a powerful sleep aid, and insomnia patients have often claimed that magnesium supplementation is the reason. A single serving of hemp seed contains nearly 50% of the daily recommended dose of magnesium, so grab a handful and get guaranteed beneficial and restorative sleep.
