Introduction: Oranges have many benefits, but it is best to eat them regularly, not excessively. Because orange flesh contains certain organic acids, to avoid irritation to the gastric mucosa causing discomfort and being detrimental to the stomach, it is recommended not to eat oranges on an empty stomach.
Control Your Intake
According to research, eating 3 oranges a day can meet a person's daily requirement of vitamin C. If you eat too many, excessive intake of vitamin C will increase oxalic acid metabolism in the body, which can easily lead to urinary stones and kidney stones. Additionally, eating too many is harmful to the mouth and teeth.
Not Recommended Before Meals or on an Empty Stomach
Although oranges have many benefits, it is best to eat them regularly, not excessively. Because orange flesh contains certain organic acids, to avoid irritation to the gastric mucosa causing discomfort and being detrimental to the stomach, it is recommended not to eat oranges on an empty stomach.
Not to be Eaten with Radishes
After radishes enter the human body, they quickly produce a substance called sulfate, which is rapidly metabolized into an anti-thyroid substance—thiocyanate. If oranges are consumed at this time, the flavonoids in the oranges will be broken down in the intestines and converted into p-hydroxybenzoic acid and ferulic acid. These can enhance the inhibitory effect of thiocyanate on the thyroid, thereby inducing or causing goiter.
Oranges and Milk Should Not Be Eaten Together
The protein in milk is prone to react with the citric acid and vitamin C in oranges, coagulating into clumps. This not only affects digestion and absorption but can also cause symptoms such as bloating, abdominal pain, and diarrhea. Therefore, it is not advisable to drink milk within 1 hour before or after eating oranges.
Elderly Should Eat Less
Elderly people with weak gastrointestinal, kidney, or lung function, or those with a "deficiency-cold" constitution, should not eat too many to avoid inducing conditions like abdominal pain, soreness in the lower back and knees.
Those with a "Yin Deficiency" Constitution Should Not Eat
In Traditional Chinese Medicine, oranges are considered "warm" in nature. Eating too many can easily lead to "internal heat." This is especially true for those with a "Yin deficiency and Yang excess" constitution; it is best to eat fewer, otherwise, symptoms such as mouth sores, dry mouth and throat, sore throat, and constipation may occur. It is recommended to eat some tangerines to avoid these "internal heat" symptoms.
Children Should Not Eat Too Many
Children who are greedy and eat too many oranges can easily develop "internal heat." If a child eats too many oranges and shows signs of "internal heat," such as glossitis, periodontitis, or pharyngitis, they should stop eating them for 1-2 weeks before resuming.
In addition, oranges also contain a large amount of carotene. If consumed in excess at one time or continuously in large amounts recently, the high concentration of carotene in the blood will cause the skin to turn yellow. At this point, besides drinking more water and temporarily not eating citrus fruits, you should also limit foods rich in carotene. After about a month, the skin color will return to normal.
Cherries are delicious but hard to grow, oranges are delicious but hard to pick. Here are some tips for selecting oranges, shared with you.
"Genetics"—Origin and Variety is the root. This determines the general direction of the overall quality of the oranges you buy. Common orange varieties in Beijing include Satsuma mandarins, Nanfeng oranges, rock sugar oranges, Huangyan蜜橘 (Huangyan honey oranges), and tangerines, among which Satsuma mandarins are the sweetest. Of course, some vendors may try to pass off other oranges as Satsumas, which will test your sharp eye.
