Yogurt is a good food choice when you have a sore throat because it is cool and bland. The American Cancer Society explains that people with sore throats should choose bland foods like yogurt rather than acidic foods like oranges or spaghetti with tomato sauce, which may irritate the throat.
Certain foods are good for the voice and help promote a clear throat. Whole grains, fruit, and vegetables contain vitamins A, E, and C which help keep the throat free of mucus. If you have a sore or strained throat, try eating softer foods until the irritation clears.
