How does the body react to sugar from fruits differently to foods like cake, soda etc? Are the insulin spikes same for both the food? Why are people who are trying to lose weight or diabetic people asked to eat fruits and cut down cake and soda when both contains sugar?
In: Biology
Soda is just sugar in water. When you drink a soda, your body processes that sugar extremely fast and ram-jams it right into your liver and bloodstream.
A piece of fruit contains sugar, but it’s trapped in a sponge of fiber. The fiber is hard (or impossible) for your body to digest, and the sugar is much more slowly extracted from the chewed-up fibery mess that you swallow. The resulting blood sugar spike is much much slower – more of a bump than a spike.
Cake has a *little* fiber but besides the fat and protein of butter and eggs, it’s mostly sugar and starch, which your body converts fairly rapidly into sugar. Starch is very close to sugar and so easy to convert that your saliva actually converts it to sugar in your mouth.
