Are all sugars same?

Hi

I was wondering is all sugar the same, like all types for example:

Sugar found in potatoes/rice? Sugar found in fruit? Sugar found in honey? Sugar found in milk? White sugar?

Are all the above types the same, do they act in the same way as each other? What will cause a high spike?

Thanks

Well, yeah, but people without serious diseases have zero problems digesting disaccharides and simple starches...

On sugar metabolism: Monosaccharides like glucose and fructose are absorbed directly into the intestine. Disaccaharides require enzymes to split them into their constituents, like how sucrose must be split into fructose and glucose before it is absorbed. Starch requires a salivary/pancreatic enzyme, amylase, to be split into absorb-able glucose. Your body's ability to secrete enzymes will determine the digestibility of starches and disaccharides.

No, sugars are not the same. There are two main kinds, glucose and fructose. They are different and are metabolized by the body in very different ways. There's also starch which is a polymer of glucose and will break down to just glucose in your gut.

White sugar is 50% glucose, 50% fructose. Starch (potatoes/rice) is pretty much all glucose. Fruit is a mix of glucose and fructose, depends on the fruit. Same for honey.
