Cinnamon is available powdered from most food stores or as capsules from health food stores. Keep cinnamon in a tightly sealed container in the dark. It may be added liberally to food at meals or consumed as a supplement. Cinnamon is generally considered safe, although a recommended dose has not been established. Use cinnamon with caution if you take blood thinners or medication to lower blood glucose, as it may interact with these medicines.

A banana contains about the same amount of calories as an ear of corn -- around 110 -- yet it has two to three times the amount of sugar. A cob of corn has around 6 to 8 grams of sugar, while a banana has about 15.
