Apples are loaded with a powerful group of antioxidants called polyphenols. Although many other fruits contain polyphenols, apples have much higher concentrations.
One of the most powerful polyphenols is called phloridzin and is uniquely concentrated in the apple skin.
Phloridzin-rich apple skins have been shown to be especially active against glycation, which is one of the most reliable markers of aging. They have also demonstrated the ability to burn abdominal fat!
Glycation occurs when sugars and carbohydrates in the blood stick to proteins in the blood, creating large molecules that clump together. These large molecules damage arteries, cells and tissues throughout the body. These advanced glycation end products, or AGEs, are found at the site of most chronic degenerative diseases and considered most responsible for accelerated aging.
Apple skins rich in phloridzin block the sugar from leaving the small intestine and entering the bloodstream in the first place. If the sugar never gets into the blood, the sugars cannot glycate. In one study, phloridzin inhibited glucose (sugar) uptake by 52% (1).
Better yet, when the ice cream you ate with your apple pie gets into your blood, the phloridzin may block the sugars from sticking to the proteins, preventing glycation.
Of course, one of the (welcome) side benefits of the body burning less sugar is that it is more inclined to burn fat. In one study, patients ate 600mg of phloridzin a day for 16 weeks. The group eating the apple skin extract lost 8.9% of the original body fat and the placebo group actually gained 3.3% body fat over the same period of time (1).
While apples have gotten a bad rap for boosting blood sugar, nature seemed to be one step ahead of us and designed this amazing fruit to have it’s own blood sugar-balancing and fat-burning properties. How cool is that!
