This is one of the reasons I use NRG. It doesn't use a pre mix. Because it is dehydrated, it is minimally processed, and they use only table grade ingredients. Complete nutrition using whole foods without supplementation. (no long list of supplements at the end of the ingredients list!) Here is the formulation for the food I feed:
**Cooked free range meat, ( Vitality is available in free range buffalo, beef, chicken or wild caught salmon) naked oats, wheat germ, eggs, liver, carrots, grapefruit, winter squash, broccoli, cranberries, limes, papaya, apple, parsley, garlic, goat milk yogurt, flax seed, cider vinegar, egg shell, olive oil.
All fruits and vegetables used in all our diets are raw, and edible table grade quality.**
Here is the formulation for their grain free product:

I also like that they address issues, such as the grain vs no grain debate: http://www.nrgpetproducts.com/graindebate.html
