Here is an example of a Python dictionary with glycemic index values for common foods: ``` { "apple": { "raw": 36, "cooked": 44, "frozen and cooked": 57 }, "banana": { "raw": 51, "cooked": 51, "frozen and cooked": 50 }, "carrots": { "raw": 35, "cooked": 41, "frozen and cooked": 39 }, "white rice": { "raw": 73, "cooked": 73, "frozen and cooked": 79 }, "oatmeal": { "raw": 55, "cooked": 58, "frozen and cooked": 55 }, "sweet potato": { "raw": 70, "cooked": 63, "frozen and cooked": 82 } } ``` The keys of the dictionary are the food names, and the values are dictionaries with keys for the different preparation methods ("raw", "cooked", and "frozen and cooked") and values for the glycemic index of the food prepared in that way. This dictionary is in a format that can be easily converted to JSON for use in other programs.
