Average calories: 156 per one medium fruit.

Vitamins found in higher amounts: vitamins C, B2 and B6.

Phytonutrients found in higher amounts and their health benefits: quinces are rich in tannins (catechin and gallocatechin), which are also found in persimmons, chokecherry, and skins of bananas. The strange taste in mouth after having quince is due to tannins, which usually bind to the proteins in saliva, causing them to aggregate and resulting in a dry feeling in the mouth. Tannins have antioxidants and cancer-preventing properties.

The unique fragrance of quinces is due to the phytonutrients phenolic compounds. They are antioxidants with anti-inflammatory and anti-cancer activities.

Quinces are high in pectin. It is a soluble fiber that increases viscosity and volume of stool, making it useful in both constipation and diarrhea. Pectin is used as a demulcent as well.
