New analysis finds hempseed oil packed with health-promoting compounds

31-Jan-2014 - Spain

Long stigmatized because of its “high”-inducing cousins, hemp — derived from low-hallucinogenic varieties of cannabis — is making a comeback, not just as a source of fiber for textiles, but also as a crop packed with oils that have potential health benefits. A new study, which appears in ACS’ Journal of Agricultural and Food Chemistry, details just how many healthful compounds hempseed oil contains.

Maria Angeles Fernández-Arche and colleagues note that for millennia, people around the world cultivated cannabis for textiles, medicine and food. Hemp has high levels of vitamins A, C and E and beta carotene, and it is rich in protein, carbohydrates, minerals and fiber. In the early 20^th century, many countries banned cannabis because some varieties contain large amounts of the high-inducing compound THC. And although Colorado recently legalized recreational marijuana use — and some states have passed medical marijuana laws — the drug remains illegal according to U.S. federal law. But the European Union has legalized growing low-THC versions of hemp, and it’s making its way back into fabrics and paper. With increasing interest in plant oils as a source of healthful compounds, Fernández-Arche’s team wanted to investigate hempseed oil’s potential.

They did a detailed analysis of a portion of hempseed oil. They found it has a variety of interesting substances, such as sterols, aliphatic alcohols and linolenic acids, that research suggests promote good health. For example, it contains α-linolenic acid, which is an omega-3 fatty acid that some studies suggest helps prevent coronary heart disease. The findings could have implications in the pharmaceutical, cosmetic, food and non-food industries, they state.
