Mutton is delicious and highly nutritious, making it a favorite food among the people in our country. However, can one still eat mutton after contracting an upper respiratory tract infection? Whether it is appropriate to eat mutton depends on the specific circumstances. If the symptoms are mild after falling ill, with no fever, and the patient's appetite is still good, then it is permissible to eat mutton under these conditions. However, if the patient's symptoms are severe, with a noticeable fever and poor appetite, it is then advised not to consume mutton. In such cases, it is generally recommended to follow a light diet, avoiding greasy and spicy foods. Mutton tends to be greasy and hard to digest, which could hinder recovery from the illness.
