The St. Michael's Hospital research paper found that barley reduced both low-density lipoprotein, or LDL, and non-high-density lipoprotein, or non-HDL, by 7%.The review, which included 14 studies on clinical trials conducted in seven countries, including Canada, also indicated that barley had similar cholesterol-lowering effects as oats, which is often the go-to grain for health benefits.
"The findings are most important for populations at high risk for cardiovascular disease, such as Type 2 diabetics, who have normal levels of LDL cholesterol, but elevated levels of non-HDL or apo B," said research scientist Dr Vladimir Vuksan. "Barley has a lowering effect on the total bad cholesterol in these high-risk individuals, but can also benefit people without high cholesterol," he added. Despite its benefits, Dr Vuksan said barley is not as well-established as some other health-recommended foods, such as oats.
Barley consumption by humans has fallen by 35% in the last 10 years. Canada is one of the top five world producers of barley, almost 10 mega tonnes per year, but human consumption accounts for only 2% of the crop yield, with livestock making up the other 98%.
"After looking at the evidence, we can also say that barley is comparably effective as oats in reducing overall risk of cardiovascular disease" said Dr. Vuksan.
He said that barley can be enjoyed in a variety of ways and recommended trying to incorporate barley into existing recipes, like using it as a substitute for rice or even on its own, just like oatmeal.
