Orange pith is the spongy white substance that’s between the fruit and the peel. Many people will peel it off and eat only the fruit, because they think the pith is bitter or inedible. Usually, the pith of orange is tasteless not bitter, and contains nutrients just like the actual flesh.
Orange pith is high in fiber that may reduce bad cholesterol and contains as much vitamin C as the fruit itself. It also contains dietary flavonoids, including hesperidin, which may improve blood vessel function and reduce inflammation.
Another flavonoid found in the pith of oranges and other citrus fruits are naringenin, which has antioxidant and anti-inflammatory properties.
Research has shown that naringenin can reverse the DNA damage that causes cancer. The flavanoid may also helps lower cholesterol levels, and has some beneficial effect on weight management and metabolic syndrome – a combination of risk factors for type 2 diabetes, stroke, and heart disease.
There are many positive health benefits contained in the orange pith, so do not peel it off. If you can’t handle the taste of the pith on its own, you can add them to a smoothie or add zest to sauces, dressings, and other dishes.
