Hemp is one of the most misunderstood plants used by humans. Although it does not contain enough THC to cause a psychoactive effect, unlike the cannabis strains, guilt-by-association has meant that hemp seeds were actually banned as a food substance in Australia until April 2017! Even its many industrial uses, such as safe, natural bioplastic, have been thrown under the bus, despite its versatility, water efficiency and benefits in farmland management. Thankfully now, we Australians can enjoy the health benefits of hemp seeds legally and without unnecessary, condescending labels.
Hemp seeds are one of the only complete sources of plant protein. They contain 20 different amino acids, and nine of them are the ones that our bodies cannot produce. Three tablespoons of hemp seeds contains ten grams of protein, so it is a perfect food for vegetarians and vegans. Hemp is particularly high in the amino acid arginine, which is beneficial for heart health. A higher dietary intake of arginine is associated with lower levels of C-reactive protein, an inflammatory marker that helps to indicate cardiovascular disease risk. Three tablespoons of hemp seeds also contains one gram of fibre, which many people do not eat enough of. Eating enough fibre can prevent constipation without the use of laxatives, and aids detoxification.
Many people also do not consume enough of the essential fatty acids; the omega-6 linoleic acid and the omega-3 alpha-linolenic acid. These are present in hemp at a ratio of 2-3:1, which is considered the ideal proportion for a healthy diet. The dietary ratio of omega-6 to omega-3 fats is typically far out of balance, with proportions of 20-30:1 common. Why is this harmful? While necessary in small amounts, omega-6 fatty acids feed into a pathway that produces pro-inflammatory chemicals, and inflammation is known to fuel many chronic illnesses. Omega-3 fats feed the anti-inflammatory pathway but compete for the same enzyme as omega-6s, so these can help to prevent illness. In fact, studies on hemp seed oil or the essential fatty acids it contains have found that they can improve some markers that indicate cardiovascular disease risk.
Hemp seeds are also high in some minerals and vitamins, especially calcium, magnesium, iron and vitamin E. Magnesium deficiency is particularly common, and it is estimated that if everyone had an optimal intake of the mineral, millions of deaths worldwide would be prevented every year. Why? Well, it is involved in over 300 biochemical reactions, from heart rhythm to energy production. Overall, the nutritional value of hemp means that it could save and improve millions of lives if it were treated like just another food. Why did the Australian government, among others, jump to such illogical conclusions about the fear of "getting high" in the first place?
