Oranges are great for you, but you should enjoy them in moderation, Thornton-Wood said. Eating in large quantities "could give you gastrointestinal symptoms if you are sensitive to the high fiber content, so [it's] best to have no more than one a day," she said.
As mentioned previously, it's never wise to consume anything in excess - especially a citrus-y fruit laden with vitamin C that's heavy on the stomach. If you're eating too many oranges every day, you might experience side-effects like diarrhoea, vomiting, nausea, heartburn, bloating, cramps, and insomnia.
This time we must consult the experts, because, according to the "5 a day" Scientific Committee, a piece of 100 or 150 grams provides the nutritional values we need throughout the day. Therefore, taking into account the weight and measurements of the fruit, the ideal is to eat two pieces of orange a day.
Oranges have low levels of potassium, but if the body has too much potassium already, it can cause a potentially serious condition called hyperkalemia. At max, one should not consume 1-2 oranges in one day.
And with 70 mg of vitamin C in one medium-sized navel orange, per the USDA, one orange is almost all you need to meet your daily dose (according to the National Institutes of Health, the Daily Value for vitamin C is 75 mg for women and 90 mg for men).
Oranges are rich in nutrients like Vitamin A, Vitamin C and potassium which are great for your eyes. So, if you want your vision to be just as good as it is now, eat an orange every day!
Above all, in order to achieve an appreciable amount of vitamin C, we would have to eat too many - roughly 2 kilos of oranges a day to reach a dose of 1000mg.
“If an adult starts to consume oranges in large portions, say 4-5 oranges a day, the excess fibre in the body could trigger stomach upset, cramping, diarrhea, bloating, and nausea. Similarly, the excessive intake of vitamin C can cause heartburn, headache, vomiting, and even insomnia,” says Kaul.
Citrus Fruit
Although their high content of vitamin C makes them an excellent addition to any diet, citrus fruits should be avoided near bedtime.
Oranges are a vitamin-packed and healthy food, but moderation is key. They have a high concentration of acid, which can be irritating to the stomach, especially if you have gastroesophageal reflux disease (GERD). Oranges are high in potassium, so if you're on beta-blockers, eating too many can lead to kidney damage.
The best time of day to eat oranges
To assimilate all the nutrients of oranges — and this also applies to all other fruits — it is best to eat them on an empty stomach, i.e., in the morning for breakfast, after resting or fasting overnight, or as a snack between main meals.
Eating 3 oranges a day can be beneficial to your health, as oranges are packed with important vitamins, minerals, and antioxidants. Oranges can provide vitamin C, dietary fiber, vitamin A, thiamin, folate, and potassium.
Chinese restaurants that aren't big on desserts (i.e., the majority) will often serve slices of orange at the end of the meal, as a palate-cleanser after clearing away the plates.
Oranges are rich in antioxidants that work to eliminate free radicals, keeping skin healthy and free of cancer. Vitamin C and folate (Vitamin B9) improve blood flow to the skin, delivering nutrients, water and oxygen to the body's largest organ.
On digesting fruit
Its cousins, melons, as well as oranges, grapefruit, bananas and grapes, will leave your stomach in about 30 minutes. Foods rich in fiber help the digestive tract to function more efficiently. The majority of other fruits (apples, pears, kiwis, cherries, etc.) should take about 40 minutes to digest.
Oranges at breakfast stimulate the production of different brain substances, which are responsible for our mental, physical and mood. In addition to vitamin C,the most abundant in orange, it also provides us with a good and necessary dose of vitamins G, B and A, potassium, magnesium, phosphorus and calcium.
Oranges are high in vitamin C and they also keep your immune system healthy. An intense craving for orange juice or any other citrus fruits could mean your body may be fighting off an infection. Craving citrus can also mean digestive dysfunction.
They're Good for Your Gut
One medium orange has 3 grams of dietary fiber. Fiber doesn't just ward off or ease constipation. It also keeps your bowels healthy, lowers cholesterol, and controls your blood sugar levels. The fiber in oranges also helps you feel full longer.
Taking too much vitamin C can cause side effects, including: Nausea, vomiting and diarrhea. Heartburn. Stomach cramps or bloating.
The answer is simple: it's not. Orange juice is simply healthier and has many nutrients, in addition to being a rich source of vitamin C itself. Therefore, there is a greater benefit to having a whole food (fruit in this case) than a vitamin in a pill form.
The evening is not the best time because vitamin C is acidic and can cause problems when consumed on an empty stomach, especially in people with gastroesophageal reflux disease – of course the dosage matters.
