Honey This sweet treat raises your blood sugar just enough to reduce the production of orexin in your brain, a neurotransmitter that helps you stay awake. Drizzle it onto your oatmeal or take it in your tea.Sugar is higher on the glycemic index (GI) than honey, meaning it raises blood sugar levels more quickly. This is due to its higher fructose content, and the absence of trace minerals. But honey has slightly more calories than sugar, although it is sweeter, so less may be required.
