When should you not eat oranges and tangerines?

Oranges, tangerines and other fruits of this family are known to be nutritious, containing a lot of vitamin C which is very good for health, especially helping to slow down the aging process in women. However, this fruit is not recommended for some of the following subjects.

Post-operative people

According to Professor Pham Xuan Sinh, the juice of citrus fruits mostly contains relatively high levels of citric acid. They usually exist in the form of sodium citrate (a substance commonly used to prevent blood clotting). This substance will form a complex with Ca++ ions, thereby hindering the creation of prothrombinase and thrombin, which are important factors involved in the blood clotting process. Therefore, people who have had surgery on the digestive tract such as the stomach, intestines... in surgical wounds that have not fully recovered, even in cases of ulcers with a risk of bleeding... if eating citrus fruits, must be careful to avoid bleeding at the injured site.

People with stomach ulcers

Orange juice is good for health if used in the right amount and for the right person. People with stomach ulcers, duodenal ulcers or pancreatitis should not drink orange juice. Because orange juice contains acid, organic substances that increase stomach acid, cause heartburn and make ulcers worse.

According to Dr. Cao Hong Phuc, Military Medical Academy, when taking stomach medicine, drinking orange juice will have the opposite effect.especially the groups (cimetidine, omeprazole, lanzoprazole…) are drugs that are reacted in this way.

Stomach ulcer medications are drugs that can inhibit acid secretion, helping to reduce the acid concentration in the stomach; increase the pH, thereby eliminating the symptoms of the disease. Meanwhile, orange juice is rich in vitamin C and citric acid, which will contribute to increasing the acid concentration in the stomach. So, orange juice accidentally neutralizes the effect of stomach ulcer medications.

People who are taking antibiotics

Orange juice contains a lot of acid so it can damage the chemical structure of antibiotics, thereby reducing the medicinal effect of the drug.

In addition, oranges also contain a substance similar to narigin, which hinders the activation of enzymes that transport drugs. Therefore, the drug is difficult for the body to fully absorb, making the disease more difficult to treat.

It is best to drink orange juice after finishing antibiotic treatment to nourish and strengthen the body's immune system.
