But hemp, the varieties with lower THC levels, can be used for a variety of products including hemp seed foods, hemp oil, wax, resin, rope, cloth, pulp, paper, and fuel. In fact, there is a long history of using hemp for making fiber and paper.
As for nutrition (as per Wikipedia)
Approximately 44% of the weight of hempseed is edible oils, containing about 80% essential fatty acids (EFAs); e.g., linoleic acid, omega-6 (LA, 55%), alpha-linolenic acid, omega-3 (ALA, 22%), in addition to gamma-linolenic acid, omega-6 (GLA, 1–4%) and stearidonic acid, omega-3 (SDA, 0–2%). Proteins (including edestin) are the other major component (33%). Hempseed's amino acid profile is "complete" when compared to more common sources of proteins such as meat, milk, eggs and soy. Hemp protein contains all nutritionally significant amino acids, including the 9 essential ones adult bodies cannot produce. Proteins are considered complete when they contain all the essential amino acids in sufficient quantities and ratios to meet the body's needs. The proportions of linoleic acid and alpha-linolenic acid in one tablespoon (15 ml) per day of hemp oil easily provides human daily requirements for EFAs.
A Canadian firm has taken a lead in moving the hemp hearts, a highly nutritive component into the US. According to the Bloomberg article below, the company is looking to triple its production to meet the increasing demand.
Hemp Enters the Mainstream
By Matthew Boyle May 22, 2014
The sachets of hemp hearts on the shelves at Costco (COST), Safeway (SWY), and Whole Foods Market (WFM) are Mike Fata’s last laugh. The founder of Manitoba Harvest has spent the past decade working to transform hemp—a variety of cannabis—from the butt of weedy jokes into a supermarket staple. Fata’s investors are particularly happy about the mass-market breakthrough. “Our customers are bright enough to know that it does not have dope in it if Costco’s selling it,” says Jim Taylor, a founding partner of Avrio Capital, a Calgary-based venture capital company that was one of Manitoba Harvest’s early backers.
Looser cultivation restrictions and the food industry’s hunger for produce that packs a protein punch have helped distance hemp from its more notorious relative. Hemp contains less than 0.5 percent of the mind-bending compound tetrahydrocannabinol, or THC, that gives marijuana its potency. Earlier this year the U.S. government finally recognized hemp as distinct from cannabis. A federal ban on commercial cultivation, however, is still in force.
That hasn’t stopped the flow of hemp into the U.S. from Canadian companies such as Manitoba Harvest, which this year plans to hand out 2 million samples of its hemp hearts—the soft, nutty-flavored inner kernel of hemp seeds. Hemp is easy to digest and has more protein than chia or flax. It’s also versatile: Hemp hearts can be sprinkled on cereal, yogurt, and salads or processed into powders, flour, or oil to make everything from bread to beer. “We have our eye on it,” says Colleen Zammer, a marketer in Quincy, Mass., who has worked with food and beverage companies to develop and promote healthy ingredients for the past 25 years. It’s “similar to chia in nutrition and better-tasting.”
The U.S. farm bill Congress passed in February allows it to be grown for research purposes in 14 states. Restrictions are easing as marijuana gains acceptance, and Democrats and Republicans alike support the economic boost hemp could provide industries ranging from textiles to homebuilding. “Without realizing it, many Americans already use hemp in their soaps, automobile parts, or even in their food,” says Representative Jared Polis (D-Colo.), one of the legislators behind a hemp amendment in the farm bill. “The potential for a billion-dollar-plus domestic industry is very realistic.”
Fata and two friends started Manitoba Harvest soon after hemp growing was legalized in Canada in 1988. Early on, the lingering association with pot made it hard for him and others in the nascent industry. “Some people looked at me and turned right around like they had seen the devil,” says Shaun Crew, chief executive officer of Hemp Oil Canada, a bulk supplier to the food industry.
Fata’s big break came in 2001, when Loblaw (L:CN), Canada’s biggest supermarket chain, signed on to carry the company’s products. “As we stepped up from natural food stores to mainstream stores, the stigma started to go away,” he says. Manitoba Harvest’s sales have tripled to more than $50 million in the past two years. Prices range from $1.50 for a 0.9-ounce sachet of hemp all the way up to $75 for a 5-pound pouch of certified organic hearts.
At a recent industry gathering in California, Fata introduced his latest creation: hemp heart “Snaxs” made with brown rice syrup and organic cane sugar. He figures company sales could hit $500 million over the next decade.
Whole Foods Chairman John Elstrott says Fata has helped debunk the myths surrounding hemp through education and giving out samples. The two companies sponsor the annual Hemp History Week, which this year kicks off on June 2 and features more than 175 events coast to coast, including a three-day Hemp Hoe Down in South Dakota. Celebrity backers of hemp include musician Ziggy Marley and actress Alicia Silverstone.
Fata says a $6 million expansion will triple his annual production, and he’ll soon begin scouting for a site for a new facility in Manitoba. Hemp Oil Canada is spending $13 million on a 35,000-square-foot factory scheduled to be ready by yearend.
That’s good news for food manufacturers waiting to add hemp to their products, such as Post Holdings (POST), the maker of Grape-Nuts and Alpha-Bits cereals. The company’s Erewhon brand, acquired in December 2012, has a top seller in a hemp and buckwheat cereal. Jim Holbrook, executive vice president of Post, says the St. Louis-based company is also “actively pursuing” hemp as an ingredient in an upcoming cereal from its Great Grains line.
Packaged-food giants such as ConAgra Foods (CAG) and Kraft Foods Group (KRFT) say they don’t have any current plans for hemp, leaving the market open for smaller outfits such as Nature’s Path Organic Foods. The British Columbia company sells organic hemp-seed frozen waffles, which Jillian Michaels, a personal trainer from the reality series The Biggest Loser, calls “breakfast heaven.”
