Apple's Amazing Polyphenols
In the past five years, no area of apple research has been more dynamic than the area of apple polyphenols. The balance of these phytonutrients in apples is far more unique than many researchers previously suspected.
In terms of flavonols, quercetin is the primary phytonutrient found in apples, and it's far more concentrated in the skin than in the pulp. Kaempferol and myricetin are also important apple flavonols.
Chlorogenic acid is apple's primary phenolic acid, and it's found throughout the pulp and also in the skin. Chlorogenic acid is a metabolism boosting compound also found in the popular new green coffee bean extracts. It help supress appetite and stimulate weight loss.
