I eat oranges every morning to boost my immune system and improve my skin, but recently I've been experiencing heartburn and stomach discomfort after eating them. Who should eat this fruit, and who should be cautious? Please advise! (Minh An - Hanoi )

Dr. Pham Viet Hoang, former Deputy Director of Tue Tinh Hospital (Hanoi), advises:

Oranges are not only a familiar fruit but also considered a natural source of nutrients that can boost health when consumed appropriately. A glass of fresh orange juice (about 240ml) contains approximately 112 calories, 2g of protein, almost no fat, 26g of carbohydrates, and about 21g of natural sugar. In particular, oranges are rich in vitamin C, potassium, folic acid, and antioxidants that are beneficial to the body.

Based on the nutritional values ​​above, the following groups of people should add oranges or orange juice to their daily diet:

1. People with weak immune systems

Oranges are renowned for their high vitamin C content. Just one glass of orange juice provides nearly 100% of the body's daily vitamin C requirement. This powerful antioxidant boosts immunity, helping the body fight bacteria and viruses, especially useful during seasonal changes or when feeling tired. The vitamin C in oranges also reduces inflammation and helps the body recover faster after illness.

2. People who are frequently stressed and lack sleep.
