Flavonoids
Oranges are packed with phenolic compounds — especially flavonoids, which contribute to most of their antioxidant properties. •Hesperidin. A citrus flavonoid that’s one of the main antioxidants in oranges, hesperidin may have blood pressure-lowering, anti-inflammatory, and antioxidant effects in the body (9). •Naringenin. Naringenin is another citrus flavonoid that has been linked to health benefits. Drinking naringenin-rich orange juice may help improve blood vessel function and enhance antioxidant defenses in the body (10).
Carotenoids
All citrus fruits are high in carotenoid antioxidants, which are responsible for their rich orange, red, and yellow colors. A study found that drinking fresh orange juice helped increase skin carotenoid levels, which are good indicators of total antioxidant status of the body (11). •Beta-cryptoxanthin. This compound acts as an antioxidant in the body, protecting cells against oxidative damage. In addition, your body can convert beta-cryptoxanthin into the active form of vitamin A (12). •Lycopene. Lycopene is a powerful antioxidant found in high amounts in red-fleshed navel oranges (Cara Cara oranges). It has various health benefits, and getting enough in your diet may help protect you against heart disease (13, 14, 15).
Vitamin C
Vitamin C is one of the most well-known and well-researched antioxidants. It’s essential to maintain optimal intakes of vitamin-C-rich foods and beverages like oranges. Higher dietary intake and blood concentrations of vitamin C have been linked to a lower risk of heart disease, cancer, and death from all causes (16). Summary Oranges are a rich source of several plant compounds that may be responsible for many of their health benefits.
Helps promote heart health
Heart disease is currently the world’s most common cause of premature death. A number of nutrients and plant compounds found in oranges, including vitamin C, flavonoids, and carotenoids, may help promote heart health and reduce the risk of heart disease if you consume them at optimal levels (16, 17, 18). Plus, regularly consuming oranges and orange juice may help reduce heart disease risk factors. One review of 10 high quality studies found that consuming orange juice reduced several heart disease risk factors, including levels of (19): •blood sugar •LDL (bad) cholesterol •the inflammatory marker C-reactive protein (CRP)
Diets high in citrus fruits may protect against chronic diseases
In addition to protecting heart health, regularly consuming oranges and other citrus fruits may help reduce the risk of other health conditions, including certain types of cancer and diabetes. Studies suggest that diets high in citrus fruits may help reduce the risk of several types of cancers, including (20, 21, 22, 23): •lung cancer •mouth cancer •stomach cancer •head and neck cancer What’s more, diets high in fruits, including citrus fruits, may help reduce your risk of developing type 2 diabetes (24). One study including over 7,000 Australian adults found that those with moderate total fruit intakes that included oranges and other citrus fruits were 36% less likely to be diagnosed with diabetes at 5 years, compared with people with the lowest fruit intakes (24). Keep in mind that this study found benefits connected to eating fruits, in general, and it didn’t isolate the benefits of eating whole oranges, specifically. In addition, it didn’t find the same beneficial effects in people who drank fruit juice. This is likely because fruit juice has much less fiber and a greater effect on blood sugar compared with whole fruits. Although citrus fruits may help reduce the risk of some medical conditions if you consume them on a regular basis, remember that your diet and lifestyle as a whole are much more important than any one food.
Anemia prevention
Consuming vitamin-C-rich foods may help prevent anemia, a condition that occurs when your body lacks adequate amounts of the mineral iron. Although oranges are not a good source of iron, they’re an excellent source of vitamin C, which enhances your body’s ability to absorb iron (7). One study found that adding 120 grams of orange to meals composed of rice or flatbread with lentils or a greens-based dish called saag enhanced the bioavailability of iron by as much as 10.7% (25). Try adding a sprinkle of orange juice to lentil and bean dishes, or adding orange segments to spinach salads to help enhance iron absorption.
Fiber content
One of the main differences between pure orange juice and whole oranges is that juice is much lower in fiber. One cup (248 mL) of pure orange juice has nearly double the calories of a whole orange and contains almost twice as much sugar. Plus, orange juice contains much less fiber than whole oranges, so it’s much less filling (3, 4). As a result, fruit juice is much easier to overconsume than whole oranges. Drinking too much of any fruit juice isn’t good for your overall health because it could contribute to excessive calorie consumption.
Added sugar
Plus, some orange juices contain added sugars, which you should keep to a minimum for optimal health. Although quality orange juice can be a healthy choice when you consume it in moderation, choosing whole fruit more often is a smart choice. Summary Fruit juices are more concentrated in sugar and contain less fiber, making them much less filling than whole fruit.
Oranges don’t have many known adverse effects.
Although rare, orange allergies do exist. If you’re allergic to oranges, you should avoid eating oranges or drinking orange juice (30).
For people who experience heartburn, eating oranges can make symptoms worse. This is because oranges contain organic acids, mainly citric acid and ascorbic acid (vitamin C) (31).

They are a good source of vitamin C, as well as several other vitamins, minerals, and antioxidants.
Some studies show that consuming citrus fruits like oranges on a regular basis may help lower the risk of certain health conditions, such as heart disease.
