Why are apples a low-sugar fruit because they are quite sweet?

The sweetness of fruit is not only related to the level of sugar content, but also related to the type of "sugar" and the content of acidic substances.

The "sugar" in fruits mainly includes monosaccharides (fructose, glucose) and disaccharides (sucrose), maltose) and polysaccharides (starch), of which starch has basically no sweetness. In addition, fruits also contain varying degrees of organic acids (fruit acid, citric acid, tartaric acid, tannic acid, etc.), which can make the sweetness of the fruit less obvious.

Apples have low sugar content and are low-sugar fruits. Apples are cool and sweet. No matter what kind of apples, proper consumption not only has obvious effects of replenishing qi and relieving coughs, but also strengthens the stomach and spleen. When you eat apples, the sugar in them will be absorbed slowly and evenly, so it has a good blood sugar-lowering effect, especially after meals. It can be said that eating apples regularly is very beneficial to diabetics.
