Hello Sudhir Ji,
Vitamin C-rich fruits like oranges are good for immunity but should be consumed in moderation, as they can be acidic and may irritate the stomach in some cases. To help with recovery, focus on a balanced diet with hydrating fluids, anti-inflammatory foods (ginger, turmeric), and lean proteins. Avoid processed foods, excessive dairy, and alcohol, as they can hinder healing. Always follow your doctor's advice for dietary modifications based on your health condition.
