I found a good website for planning food other than the commercial dehydrated meals.

http://caloriecount.about.com

If you create an account, it will analyze the nutrients. I found my backpacking diet was completely lacking in potassium and low in calcium. A cup of dehydrated fruit will fix that.

I also found I could increase the calorie count and nutrient by at least 10% for the same weights just by picking a different brand of food.

All this is probably overkill for an overnight hike. But if the calorie count can be increased by 10%, it means about a 10% reduction in food weight or maybe an increase in energy for the same weight. For a longer hike, this can make a difference.
