A 2013 research review published in the American Journal of Lifestyle Medicine suggested that cinnamon could have real benefits when it comes to Type 2 diabetes, even though some of the human research results have been mixed. “Despite the mixed results coming from studies of cinnamon in type 2 diabetic patients, there is promise in its potential effects. Large, randomized, placebo-controlled studies of cinnamon need to be completed in order to fully evaluate its efficacy,” the researchers wrote in their conclusions. “However, due to the significant amount of favorable studies in patients with uncontrolled type 2 diabetes, cinnamon is a reasonable treatment option in this population. Cinnamon’s low cost, over-the-counter availability, and safety profile make it a relatively low-risk alternative to traditional glucose-lowering medications.” But before you start dumping the stuff on everything you eat, take note: They say maximum medical benefits likely come from taking capsules of cassia (Chinese) cinnamon.
