If you’re a fan of citrus fruits, you’ve probably enjoyed your fair share of oranges.
Citrus sinensis, or the sweet orange, is the type people typically enjoy fresh and in juice form.
Oranges are a treasure trove of nutrients and protective plant compounds, including vitamins, minerals, and antioxidants. Studies show that consuming oranges regularly may benefit your health in several ways.
This article explains everything you need to know about oranges, including their nutritional value, potential health benefits, and more.
Here’s the nutritional breakdown for 1 orange (140 grams) (3Trusted Source):
- Calories: 66
- Water: 86% by weight
- Protein: 1.3 grams
- Carbs: 14.8 grams
- Sugar: 12 grams
- Fiber: 2.8 grams
- Fat: 0.2 grams
- Vitamin C: 92% of the Daily Value (DV)
- Folate: 9% of the DV
- Calcium: 5% of the DV
- Potassium: 5% of the DV
Like most fruits, oranges mainly comprise carbs and water, contain very little protein and fat, and are relatively low in calories.
Getting enough fiber on a daily basis is essential for overall health and helps keep your digestive system healthy by supporting regularity and fueling your beneficial gut bacteria.
Oranges are also high in certain nutrients, especially vitamin C and folate.
One 140-gram orange covers 92% of your daily vitamin C needs. This water-soluble nutrient is essential for your health. Your body uses it for immune function, collagen synthesis, iron absorption, and more (7Trusted Source).
Folate is a B vitamin that plays a role in metabolism, fetal and placental development, and many other important processes (8Trusted Source).
In addition to vitamin C and folate, oranges provide smaller amounts of other nutrients, including calcium, potassium, and thiamine (vitamin B1).
Oranges are a good source of fiber and a rich source of vitamin C and folate, among many other beneficial nutrients.
Oranges are an excellent source of various bioactive plant compounds that have anti-inflammatory and antioxidant effects. These include flavonoids, carotenoids, and vitamin C.
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 (9Trusted Source).
- 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 (10Trusted Source).
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 (11Trusted Source).
- 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 (12Trusted Source).
- 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 (13Trusted Source, 14Trusted Source, 15Trusted Source).
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 (16Trusted Source).
Oranges are a rich source of several plant compounds that may be responsible for many of their health benefits.
According to research findings, regularly consuming citrus fruits, like oranges, may benefit your health in a number of ways.
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 (16Trusted Source, 17Trusted Source, 18Trusted Source).
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 (19Trusted Source):
- 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.
- lung cancer
- mouth cancer
- stomach cancer
- head and neck cancer
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 (24Trusted Source).
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.
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 (7Trusted Source).
One study found that adding 120 grams of orange to meals composed of rice or flatbread with lentilsor a greens-based dish called saag enhanced the bioavailability of iron by as much as 10.7% (25Trusted Source).
Try adding a sprinkle of orange juice to lentil and bean dishes, or adding orange segments to spinach salads to help enhance iron absorption.
May help support immune health
Regularly consuming fruits, which are high in vitamins, minerals, and antioxidant compounds, can help promote healthy immune function.
Oranges and other citrus fruits are excellent sources of vitamin C.
This nutrient is critical to the function of immune cells like natural killer cells. It’s likewise necessary for a process called apoptosis, in which old, damaged cells die, then are cleared out and replaced with new healthy cells (26Trusted Source).
Vitamin C is a powerful antioxidant and helps protect against the process of oxidative damage, which otherwise can negatively affect immune health and increase disease risk (27Trusted Source).
Many other compounds in oranges, including hesperidin and naringenin, have anti-inflammatory activities.
Fiber is another nutrient provided by oranges that can help promote immune health. Your body needs fiber to maintain a healthy balance of gut bacteria, which influence immune system development and function (28Trusted Source).
Oranges may benefit heart health, reduce the risk of some chronic diseases, enhance iron absorption, and support a healthy immune response.
Orange juice is one of the most frequently consumed juices in the United States (29Trusted Source).
It’s sweet, refreshing, and provides a number of important nutrients and beneficial plant compounds.
Even though both orange juice and whole oranges are nutritious, there are several differences between the two.
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 (3Trusted Source, 4Trusted Source).
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.
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.
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 (30Trusted Source).
Some people are allergic to oranges, and their acidity may increase the symptoms of heartburn. However, oranges pose few health risks overall.
Oranges are among the world’s most popular fruits — they’re as nutritious as they are tasty.
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.
Put simply, this bright citrus fruit is an excellent addition to a healthy diet.
