Is Orange Peel As Healthy As The Fruit Inside?

Hold on to that orange peel! It is just as (or maybe even more) precious as the juicy fruit it holds. Its rich flavonoid content can help ward-off inflammation, thus lowering your risk of various degenerative diseases including Alzheimer's, cancer, and heart disease. Orange peels and their oils are great digestive aids and can also be used as teeth whiteners and face masks.

Many of us already know that the vitamin C in oranges makes them great immunity boosters. Feeling a cold come on? Grab an orange! But what most of us don’t realize is that we’re often tossing out the most nutritious part of the fruit – the peel!

The Cover Story

Most fruits have a protective covering, either a hard rind or tough peel. This exterior contains a wealth of vital nutrients and other wellness-promoting compounds, including dietary fiber. The fruit of the orange, aka Citrus genus, is typically consumed raw or used to make a variety of foods like jams and cakes. But its peel, and the oil from that peel, can be used in multiple ways. Researchers are discovering numerous uses for the peel as both a disease fighter and an effective ingredient in cosmetics, medicines, air fresheners, whiteners, cleaning agents, and even compost.

The Protective Peel

Hold on to that orange peel – it’s just as (or maybe even more) precious as the juicy fruit it holds. Across multiple studies, the orange peel has proven to provide immense health benefits. The peel is especially rich in flavonoids – organic compounds found in plants and categorized as plant secondary metabolites – which have shown to be useful in anti-fungal and anti-inflammatory treatments.1

Derived from the peel, citrus oils contain anti-microbial properties that are effective against bacteria. In both oil and vapor form, they can also be used as a safe, natural food additive.2

Many Uses For The Rich Peel

Fighting The Big C

Perhaps some of the most fascinating studies have looked into the citrus peel’s anticancer properties. Researchers have found that the polymethoxyflavones (PMFs), a type of flavonoid found in peels, act as a protective agent in fighting off cancer cells. PMFs seem to prevent carcinogenesis by blocking the metastasis cascade (spreading to other organs) and reducing the ability of cancer cells to move through the circulatory system.3

Your Diet’s Best Friend

Orange peels are high in dietary fiber, but who wants to bite right into that thick and bitter peel? Fortunately, you can consume the orange peel in powder form as a way to add more fiber to your diet. The peel consists of about 61–69% fiber, with a significant portion of that being soluble fiber (19–22%) – a great digestive aid.4

Keeping Inflammation Away

Chronic inflammation is a major cause of various degenerative diseases, including cardiovascular diseases, Alzheimer’s, diabetes, and cancer. Again, the flavonoids in the orange peels are the true stars here. They can easily permeate through membranes. This is called “bioavailability” and it’s inspired researchers to study the potential use of flavonoids in the prevention and treatment of various diseases. One notable thing they’ve found is that these flavonoids in the orange peel can act as an anti-inflammatory drug.5

Fungus Fighter

Several studies have also proven that orange peel oils can be effective in fighting fungal infections. One study found that the vapors show greater effectiveness, while the oil produces faster results.6

Always Save The Peel!

Would you believe there are even more handy ways to use the orange peel? You don’t need to be a doctor or scientist to reap its benefits. With its rich supply of vitamin C, orange peels and their oils can also be used as teeth whiteners, face masks, cleaning and composting agents, air fresheners, and natural insect repellants. So, after enjoying the delicious, juicy orange to nourish your body, use the peel to freshen up your skin, your teeth, and your home!
