Oranges are packed with vitamins and minerals, beta-carotene, potassium, magnesium, and fiber. Their alkalizing and detoxifying properties keep your body healthy. They are rich in vitamin C, a powerful antioxidant.
An average orange benefits your health in various ways. It may aid weight loss and also boost immunity. Its anti-inflammatory, antiviral, and antimicrobial properties could benefit humans in various ways. Orange juice has anti-inflammatory properties, and studies suggest it could help in the treatment of chronic diseases (1).
The properties of oranges offer a host of health benefits. In this post, we will see what those benefits are and what scientific studies back them up.

What Are The Health Benefits Of Oranges?
1. May Aid Weight Loss
Reports suggest that the fiber in oranges may promote satiety, which may contribute to weight loss. Whole oranges were found to promote satiety better than orange juice (which is devoid of fiber) (2).
The fiber in oranges can keep you full, and you end up eating less. You can substitute this low-calorie fruit for desserts, which will not leave you craving for sweets.
2. May Delay Skin Aging
Oranges, like most other citrus fruits, may help prevent UV-induced skin damage. In mouse studies, the ingestion of unripe citrus extracts could decrease wrinkle depth and slow down collagen degradation (3).
Oranges contain organic acids, vitamins, minerals, vitamin C, and flavonoids. These could play a role in skin health (3).
Some anecdotal evidence suggests that the topical application of oranges may also nourish the skin. Their water content may also hydrate the skin and accelerate collagen production. However, more research is needed to establish this.
3. May Regulate Blood Pressure Levels
Oranges (and their juice) are rich in potassium, which helps regulate blood pressure. Some studies also suggest that commercial orange juice may have a significant effect on blood pressure and other associated ailments (4).
4. May Lower Cholesterol Levels
Long-term intake of orange juice was associated with lower cholesterol levels in men and women. The juice could reduce total cholesterol levels and the levels of bad cholesterol (5).
Oranges are rich in fiber (pectin). Rat studies show that this fiber can help lower cholesterol levels in the liver and serum (6).
Fiber may also prevent your digestive tract from absorbing cholesterol. It also is believed that in addition to fiber, vitamin C, potassium, and flavonoids in the fruit may also help lower cholesterol.
5. May Promote Heart Health
The vitamin C in the fruit also keeps blood from clotting. This prevents thrombosis (local blood clotting) and reduces the risk of a heart attack (7).
The potassium in oranges, as discussed, can lower blood pressure and reduce the risk of cardiovascular diseases (4).
6. May Aid Diabetes Treatment
In a Nigerian study, oranges, along with other fruits, were considered safe to be eaten by those with diabetes. This had to do with the healthy glycemic response the fruit had in the body (8).
The pulpiness of the fruit serves as a great source of fiber. Fiber helps in slowing down the absorption of sugar and improving the blood sugar levels (9).
However, there is no research if orange fiber, in particular, helps lower blood glucose levels. Some believe the moderate glycemic index of oranges may help in diabetes, but this also has not been proven.
To completely absorb the fiber, avoid extracted juices, and go for the whole fruits (10).
7. May Prevent Kidney Stones
Citrate deficiency in urine can cause kidney stones. Oranges (and their juice) can help increase citrate levels in your urine, reducing the risk of kidney stones (11).
Oranges (and the juice) also contain calcium that may reduce the risk of stones (11).
8. May Help Treat Anemia
The vitamin C in oranges may promote iron absorption. Iron cannot be fully absorbed in the body without the help of vitamin C (a nutrient that oranges are loaded with) (12). Snacking on at least one orange every day may help in the treatment.
9. May Help Boost Immunity
Oranges are rich in vitamin C. Some research states that this nutrient can help boost immunity (14). Though there is no direct research stating oranges can promote immunity, its vitamin C content could help.
The fruits contain many other essential nutrients like folate and copper, which may also promote immune health.
10. May Reduce The Risk Of Colon Cancer
Rat studies show that orange juice may help inhibit colon cancer. The fruit (and its juice) contain hesperidin, which is a flavonoid with chemopreventive potential (15).
The fiber in oranges may help reduce the risk of colon cancer. Oranges also contain other important chemopreventive agents that help in this regard (16).
However, some research states that a high intake of orange/yellow fruits may increase the risk of colorectal cancer in men. The mechanism behind this is yet to be studied (17).
The fiber in oranges also helps treat constipation and aids digestion. It is believed that the less fructose in oranges makes them less likely to cause gas. Research is limited here, though.
11. May Promote Eye health
You must have heard how orange-colored fruits and vegetables promote eye health and protect vision. Eating oranges can offer significant eye benefits as the flavonoids in them help boost vision health. Studies showed that participants who consumed oranges were found to have a reduced risk of age-related macular degeneration (18).
Additional studies are required to validate these findings.
12. May Help Treat Polycystic Ovary Syndrome
You should follow a diet that contains low glycemic index foods to combat PCOS. Orange has a low glycemic index and is suitable for those with PCOS. Oranges also improve insulin resistance, which is thought to be the origin of PCOS (19).
Oranges are quite popular. They taste refreshing, but more importantly, they contain important antioxidants that promote human health. Though oranges are common, they are available in different types that we may not be aware of.
What Are The Different Types Of Oranges?
The most common types of oranges are the Washington navel, blood oranges, and valencia.
Oranges are likely to have originated in southern China, northeastern India, and other parts of southeastern Asia. They have since been hybridized, re-hybridized, and altered so much that there are hundreds of orange varieties found around the world today.
While we have understood the benefits of oranges, it is important to understand the fruit’s nutritional values and its various applications that make it so potent.

In pre-historic times, Europeans recognized the medicinal properties of oranges and stocked them on long sea voyages to prevent scurvy. These citrus powerhouses are important sources of vitamin C and folate. Oranges also contain significant antioxidants, such as beta-carotene and other flavonoids.
But does this mean you can eat as many oranges as you want? Well, maybe not. Excess intake of oranges may cause certain undesirable effects.
What Are The Side Effects Of Eating Too Many Oranges?
Oranges are great for you, but only when consumed in moderation.
As they are highly acidic, oranges may lead to heartburn if consumed in excess. They can also aggravate symptoms of GERD (gastroesophageal reflux disease) (20).
Due to their acidic content, eating too many oranges can also lead to indigestion (21).
Consuming too many oranges may also cause abdominal pain. One study states the case of an individual who had developed severe abdominal pain after consuming oranges. Its high fiber content could be the reason (22).
Some anecdotal evidence states that eating too many oranges may also lead to diarrhea. However, we need more research to prove this statement.
Hence, it is important you keep a check on the number of oranges you are consuming in a day.
How Many Oranges Can You Eat In A Day?
There is no concrete research on this – but looking at the high vitamin C levels and the abundance of other beneficial phytochemicals, you can consume one to two oranges a day.
The antioxidants and other anti-inflammatory compounds in oranges help treat and prevent chronic disease. However, ensure you do not consume them in excess. Eating one to two oranges a day is sufficient.

Freeze them whole, in pieces, or packed in syrup.
