Studies have shown that cannelle may lower blood sugar levels, especially in people with 2 type diabetes whose blood sugar is poorly controlled. According to one of them, the daily consumption of a capsule of cinnamon extracts allowed the levels of glycemia and blood lipids, of the 30 people observed, to drop by 25% in 40 days.¹ This spice acts on insulin, a hormone secreted by the pancreas and responsible for the control of sucre in the blood. In order to benefit from its effects, it is recommended to consume 1 to 6 g per day, or ½ teaspoon (5 ml) to 1 tablespoon (15 ml).
