Are Oranges Good for You? 9 Benefits, Calories & Recipes

Yes, oranges are good for you, because they are rich in vitamin C, fiber, and flavonoids, such as hesperidin. These nutrients help support the immune system, promote healthy digestion, lower LDL (“bad”) cholesterol levels, and maintain healthy skin.

One medium orange (about 131 g) contains approximately 62 calories and 70 mg of vitamin C, providing most of the recommended daily intake for adults. Oranges also provide potassium and folate and have a low glycemic index, making them a suitable choice for people with diabetes when eaten whole.

To enjoy these benefits, you can eat one orange a day as part of a healthy, balanced diet. Eating whole oranges is generally preferable to drinking orange juice, as whole fruit provides more fiber and helps slow sugar absorption. Oranges can also be used in simple, healthy recipes, like cakes, cookies, and orange peel tea.

Health benefits

The main health benefits of oranges are:

1. Improving digestion

Oranges contain fiber, like pectin, cellulose and hemicellulose, which adds bulk to stool and helps it move through the gut. This makes oranges useful for preventing and relieving constipation.

Pectin is a soluble fiber that absorbs water in the intestine and forms a gel. This gel softens the stool and makes bowel movements easier.

2. Lowering bad cholesterol

The soluble fiber in oranges, particularly pectin, helps lower LDL ("bad") cholesterol by binding to bile acids in the digestive tract and promoting their elimination from the body. This may help reduce the buildup of fatty plaques in the arteries and support cardiovascular health.

Oranges also contain hesperidin, a flavonoid with antioxidant properties that may benefit heart health.

Some studies suggest that hesperidin can help reduce cholesterol, triglyceride levels, and systolic blood pressure. However, most of these studies have used supplements containing much higher doses of hesperidin than those naturally found in a single orange.

3. Helping control blood pressure

Oranges contain potassium, an essential mineral that helps the body eliminate excess sodium and relax blood vessel walls, supporting healthy blood pressure levels. Regularly eating potassium-rich foods may help lower blood pressure, particularly in people with hypertension.

One medium orange provides approximately 5% to 7% of an adult's daily potassium needs. For greater benefits, oranges should be included in a balanced diet alongside other potassium-rich foods, such as beans, bananas, and leafy greens.

4. Helping manage blood sugar

Oranges have a low glycemic index (around 43) and contain fiber, which slows sugar absorption in the digestive tract and helps prevent sharp rises in blood sugar levels after meals.

People with diabetes can include oranges in their diet, preferably eating one small to medium whole orange at a time.

Whole oranges are a better choice than orange juice because they contain more fiber and generally lead to a slower rise in blood sugar.

5. Strengthening the immune system

Oranges have a low glycemic index (around 43) and contain fiber, which slows sugar absorption in the digestive tract and helps prevent sharp rises in blood sugar levels after meals.

People with diabetes can include oranges in their diet, preferably eating one small to medium whole orange at a time. Whole oranges are a better choice than orange juice because they contain more fiber and generally lead to a slower rise in blood sugar.

6. Keeping skin healthy

Vitamin C is needed to produce collagen, a protein that keeps skin firm and elastic. Because it is also an antioxidant, vitamin C helps fight free radicals, which contribute to premature skin aging.

7. Preventing anemia

Oranges contain vitamin C and citric acid, which enhance the absorption of iron from plant-based foods, such as beans, lentils, and spinach. This can help maintain healthy iron levels and reduce the risk of iron-deficiency anemia.

To make the most of this benefit, eat an orange for dessert after a meal rich in plant-based sources of iron. Oranges also provide folate, an essential nutrient for the production of healthy red blood cells.

8. Supporting weight loss

Oranges are low in calories and high in water and fiber, which help promote a feeling of fullness, control appetite, and support weight management.

Regularly eating fruits and vegetables is also associated with weight loss and improved weight management in people with overweight or obesity.

Whole oranges are a better choice than orange juice for weight loss because they provide more fiber, help you feel full for longer, and make it easier to control calorie intake.

9. Possibly lowering the risk of some cancers

Oranges are rich in antioxidants, such as vitamin C and flavonoids, which help protect cells from damage caused by free radicals.

Observational studies involving large populations suggest that higher citrus fruit consumption may be associated with a lower risk of colorectal cancer. However, these findings do not establish a direct cause-and-effect relationship, and further human studies are needed to confirm this potential benefit.

Nutrition facts

The following table shows the nutritional information for 100 g of orange, fresh orange juice and orange peel:

A small orange (about 96 g) has around 45 calories, a medium orange (131 g) has about 62 calories and a large orange (184 g) has about 86 calories. One medium orange also provides about 3 g of fiber, 12 g of natural sugar and 70 mg of vitamin C.

To get all of the benefits listed above, oranges should be part of a healthy, balanced diet together with regular physical activity.

Types of oranges

The most common types of oranges in the US are:

• Navel oranges: seedless and sweet, with an easy-to-peel skin. They are best eaten fresh, because their juice turns bitter after a while.
• Valencia oranges: juicy, with thin skin and a few seeds. They are the most used type for making orange juice.
• Cara Cara oranges: a type of navel orange with pinkish-red flesh. They are sweet, low in acid and contain lycopene, an antioxidant also found in tomatoes.
• Blood oranges: have deep red flesh because of anthocyanins, antioxidants also found in berries. They taste slightly tart, like raspberries.
• Mandarin oranges: smaller and easier to peel, and include clementines and tangerines. They have similar nutrients to oranges, with a little less vitamin C per fruit.
• Seville oranges: also called bitter or sour oranges. They are too sour to eat raw and are mostly used for marmalade and sauces.

All types of oranges can be eaten on their own or added to juices, cakes, sauces and salads.

Whole oranges vs. orange juice

Whole oranges are the healthiest option, because they keep all the fiber of the fruit. A cup of orange juice needs about 3 oranges to make, and it has much less fiber and more sugar than a single orange.

The Dietary Guidelines for Americans recommend eating fruit in its whole form and drinking 100% fruit juice only in small portions or diluted with water. Drinking juice every day is linked to weight gain, especially in children.

If you drink orange juice, choose 100% juice with no added sugar and keep it to a small glass (about 4 oz or 120 mL). Fresh, homemade juice should be consumed right after it is made, because vitamin C breaks down when exposed to air and light.

How to eat oranges

Oranges can be eaten fresh, as juice or added to recipes for salads, sauces, cakes, jams and desserts. Raw oranges have more nutrients than cooked ones, because vitamin C is lost with heat.

The peel can also be eaten, as it is rich in fiber, vitamin C and antioxidants. It can be grated into zest for cakes and cookies, candied or used to make tea.

Wash the orange well before using the peel, or choose organic oranges, to remove dirt and pesticide residue.

Possible side effects

Oranges are safe for most people, but eating too many can cause bloating, gas or diarrhea because of their fiber content.

The acid in oranges can also worsen heartburn in people with gastroesophageal reflux disease (GERD).

People with diabetes should prefer whole oranges over juice and spread their fruit portions throughout the day.

People with chronic kidney disease who need to limit potassium should check with their doctor or dietitian about how many oranges they can eat.

People who take medication every day and want to consume products made with Seville (bitter) orange, such as supplements, should talk to their doctor first.
