Oranges: Health Benefits

There are thousands of reasons why eating an orange a day is a good idea; they are low in calories but full of nutrients, they promote clear, healthy skin and can help to lower our risk for many diseases and conditions as part of an overall healthy and varied diet.

An orange has over 170 different phytochemicals and more than 60 flavonoids, many of which have been shown to have anti-inflammatory properties and strong antioxidant effects.

Nutritional breakdown of oranges

One medium orange (approximately 154 grams) contains 80 calories, 0 grams of fat, 250 milligrams of potassium, 19 grams of carbohydrate (14 grams of sugar and 3 grams of dietary fiber) as well as 1 gram of protein.

One orange provides 130 percent of your vitamin C needs for the day, 2 percent of vitamin A needs, 6 percent of calcium and 0 percent of iron.

Oranges also contain thiamin, riboflavin, niacin, vitamin B-6, folate, pantothenic acid, phosphorus, magnesium, manganese, selenium, and copper. Because of their high vitamin C content (over twice the daily need), oranges are associated with boosting the immune system.

Oranges also contain choline, zeaxanthin, and carotenoids.

Choline is an important nutrient found in oranges that help with sleep, muscle movement, learning, and memory. Choline also helps to maintain the structure of cellular membranes, aids in the transmission of nerve impulses, assists in the absorption of fat and reduces chronic inflammation.

Zeaxanthin and carotenoids have antioxidant effects and have been shown to have an inverse relationship with overall cancer rates and prostate cancer in particular.

How to incorporate more oranges into your diet

Orange segments
There are a variety of orange types on offer that can aid in various conditions from heart health to diabetes.

Oranges should be picked at their peak of ripeness because unlike some other fruits, they do not ripen or improve in quality after being picked. Oranges should be stored at room temperature, away from direct sunlight.

While it is hard to find good fruits and vegetables in the winter, it is the perfect time to buy citrus. Winter is the peak season for oranges and other citrus fruits.

There are many different types of oranges available such as navel, mandarin, caracara, blood oranges, Valencia and Seville oranges just to name a few. Some are very sweet and others have more of a sour taste.

Tips for oranges:

  • Keep a bowl on the kitchen table or counter stocked with fresh fruit from the season. Seeing the fruits readily available will likely cause you to choose them as a snack more often rather than raiding the cupboards for a less healthy snack.
  • Make a fruit salad with strawberries, pineapple, mandarin oranges, and grapes.
  • Add some orange slices to your salad at lunch or dinner. Compliment the oranges with walnuts or pecans, a crumbled cheese, and a light balsamic or citrus vinaigrette dressing.
  • Make your own juice! Nothing tastes better than freshly squeezed orange juice in the morning. When you make your own, you can be sure there are no added preservatives or sweeteners.

Possible health risks of oranges

Beta-blockers, a type of medication most commonly prescribed for heart disease, can cause potassium levels to increase in the blood. High potassium foods such as oranges and bananas should be consumed in moderation when taking beta-blockers.

Consuming too much potassium can be harmful to those whose kidneys are not fully functional. If your kidneys are unable to remove excess potassium from the blood, it could be fatal.

Those with gastro-esophageal reflux disease (GERD) may experience an increase in symptoms such as heartburn and regurgitation when consuming highly acidic foods such as citrus fruit, however individual reactions vary.

It is the total diet or overall eating pattern that is most important in disease prevention and achieving good health. It is better to eat a diet with variety than to concentrate on individual foods as the key to good health.
