is this a good food for hamsters?

Despite the added mealworms the crude protein levels are very low honestly, so I wouldn't consider it to be a good diet in terms of a base food providing proper nutrition in terms of macronutrients even if micronutrients are probably covered there.

In terms of proper diet that provides the right nutrition, it really depends on where you are in the world. In the US & Canada for example the proper diet would be Higgins Vita Garden(not Sunburst which has dried fruit that isn't exactly the best thing to have in a daily diet for any hamster species even for non diabetes prone species), with the addition of daily flax seeds & Pure Bites or a similar high quality animal protein source.
