HFCS (high fructose corn syrup) is 55% fructose and 45% glucose. It is mostly genetically modified. Stay away!
Rapadura is the pure juice extracted from the sugar cane (using a press), which is then evaporated over low heat, whilst being stirred with paddles, then sieve ground to produce a grainy sugar. It has not been cooked at high heats or spun to change it into crystals, and the molasses is maintained in the sugar. “Sucanat” is the USA trade name for Rapadura.
Coconut sugar is made from the sweet watery sap that drips from the cut flower buds of the coconut palm. It has a low glycemic index (GI) and is rich in amino acids. It is typically less than 10% fructose, with sucrose being the primary component.
Xylitol is a sweetener known as a “sugar alcohol” (or polyol). Sugar alcohols are neither sugars nor alcohols − they are carbohydrates (with structures that happen to resemble sugar and alcohol). Xylitol is extracted from corn or birch cellulose. Unlike sugar, Xylitol is slowly absorbed, does not cause a rapid blood sugar increase, and does not require an immediate insulin response from the body to be metabolized. Moreover, many studies have shown that it actually helps prevent dental cavities, ear infections, and some evidence suggests that it helps prevent gum disease because Xylitol is anti-bacterial. However, Xylitol does have some potential health side effects (most notably gastrointestinal issues) and should be used with caution.
