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.
Industrial help has many uses, from paper and textiles to plastic and fuel. In fact, it can even be used in place of traditional paper made from trees, as hemp paper can be recycled more times than that made from wood. Hemp also yields nearly four times as much as trees. Plastic produced from hemp is also biodegradable, making it better for the environment. Hemp seeds can be used in a variety of food products as well.
Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy. Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.
Hemp is rich in omega fatty acids, which are prone to breaking down and spoiling. The one thing you want to look for when buying a bag of hemp seeds is a totally opaque package that doesn't have a window for you to look at the actual seeds. A window means the contents of the bag are being exposed to light, which means it's likelier those omegas will spoil quicker and go rancid. Also look for a "packaged on" or "best before" date on the bag and buy the newest product you can find. This will help prolong your hemp seeds' freshness.
Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks. A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production". Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material. Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.
What are the most healthful high-fat foods? Fats are an essential component of nutrition, alongside carbohydrates and protein. The key is choosing the healthful, unsaturated fats. There are many healthful high-fat foods to choose from, including avocado, chia seeds, dark chocolate, eggs, and fatty fish. Learn more about the best healthful high-fat foods here. Read now
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.
The process to legalize hemp cultivation began in 2009, when Oregon began approving licenses for industrial hemp. 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. After that, the federal government created a Hemp Farming Pilot Program as a part of the Agricultural Act of 2014. 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. Hemp production in North Carolina resumed in 2017, and in Washington State the same year. 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.
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.
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.
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.
