Back in 2003, a study in Diabetes Care showed that in thirty people with type 2 diabetes, one to six grams of cinnamon daily for forty days resulted in a drop in blood sugar levels, triglycerides, and LDL (bad cholesterol)…
But a new study, also published in Diabetes Care, has found that cinnamon doesn’t do a thing, at least for type 1 adolescents. The researchers gave 72 type 1 teens one gram of cinnamon daily in addition to their usual routine. After ninety days, the adolescents experienced no change in A1c’s, insulin requirements, or number of low blood sugar episodes. In fact, the matching group of teens who received a placebo actually did a little better than the cinnamon group, though not significantly so.
