Taboos for eating oranges
1, you can't eat more oranges.
According to the measurement, eating three oranges a day can meet everyone's daily demand for vitamin C. If you eat too much and take too much vitamin C, your body will metabolize more oxalic acid, which will easily lead to urinary calculi and kidney calculi. In addition, eating too much is harmful to the mouth and teeth. Eating too many oranges is also harmful to children's mouth, teeth and gastric mucosa.
If children eat too many oranges, the heat generated can't be converted into fat and stored in the body, and it can't be consumed in time, which will cause "excessive fire" through accumulation, manifested as stomatitis, periodontitis, pharyngitis, constipation and so on.
2, people with poor gastrointestinal function eat leisurely.
People with poor gastrointestinal function, eating too many oranges, are prone to stomach stones. Excessive consumption of citrus fruits will cause "orange peel disease" and cause symptoms such as yellowing of the skin.
Oranges and milk should not be eaten together.
Protein in milk is easy to react with fruit acid and vitamin C in oranges and coagulate into lumps, which not only affects digestion and absorption, but also causes abdominal distension, abdominal pain, diarrhea and other symptoms. You should eat oranges after drinking milk 1 hour. In addition, people with gastrointestinal, kidney and lung deficiency should not eat more, so as not to induce abdominal pain and soreness of waist and knees.
4, it is not suitable to eat with radish.
After radish enters the human body, it will quickly produce a substance called sulfate, which will soon be metabolized to produce an antithyroid substance-thiocyanate. If you eat oranges at this time, the flavonoids in oranges will be decomposed in the intestine and converted into hydroxybenzoic acid and ferulic acid, which can strengthen the inhibitory effect of thiocyanate on thyroid, thus inducing or leading to goiter.
