Hemp seeds -- sometimes called "hemp hearts" -- are sprinkled on foods, pressed for oil, ground into protein powder and made into milk. Afraid of psychotropic side effects? Don't be. While these small, pale-beige to dark-brown seeds form the edible part of the hemp plant (aka pot, ganja, weed, grass, Mary Jane, doobage), they don't contain THC, the active drug found in hemp leaf.
How much fiber should I eat per day? Most Americans eat less fiber than the USDA daily recommendations suggest. This article looks at the guidelines for fiber intake in men, women, and children. We also talk about how fiber can help with weight loss, and discuss how much fiber is too much. Learn about good sources of dietary fiber and a handy meal plan. Read now
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.
Considering its popularity from long ago, when even our forefathers appreciated the value of hemp seeds, it seems unusual that the plant would have such a bad reputation today. Both George Washington and Thomas Jefferson grew hemp plants in their gardens. Hemp paper was even used for the Declaration of Independence, and Benjamin Franklin produced hemp paper at his mill. The environmental advantages and nutritional benefits of growing industrial hemp seem to many to be worth lifting its restrictions.
In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of Cannabis that has escaped from cultivation and is self-seeding.
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 plants grow brown popcorn kernel-sized hard seeds. Inside these hard seeds lie soft, white or light green inner kernels that are packed with essential amino acids, protein, and omega-3 fatty acids. You can't really derive a lot of nutritional value from the unhulled seeds, so when you see a bag at the store labeled "hemp seeds," what you're actually buying is those soft inner kernels, also known as hemp hearts. Hemp hearts can be pressed to make hemp seed oil, leaving behind a byproduct that can be turned into hemp protein powder. You can find all of these hemp products at health food stores, or a well-stocked grocery store like Whole Foods.

Separation of hurd and bast fiber is known as decortication. Traditionally, hemp stalks would be water-retted first before the fibers were beaten off the inner hurd by hand, a process known as scutching. As mechanical technology evolved, separating the fiber from the core was accomplished by crushing rollers and brush rollers, or by hammer-milling, wherein a mechanical hammer mechanism beats the hemp against a screen until hurd, smaller bast fibers, and dust fall through the screen. After the Marijuana Tax Act was implemented in 1938, the technology for separating the fibers from the core remained "frozen in time". Recently, new high-speed kinematic decortication has come about, capable of separating hemp into three streams; bast fiber, hurd, and green microfiber.
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.
