If you or your child are experiencing ongoing problems with tonsillitis, try avoiding dairy foods for a period of 1-2 months. Dairy allergy has commonly been found to contribute to recurrent throat infection.
Eliminate all sources of concentrated simple sugars (sugar, honey, fruit juice) from the diet and instead base your diet on complex carbohydrates such as fruit, vegetables and whole grains.
Use an Echinacea, Andrographis or vitamin C supplement to help improve resistance to infection.
