Glen...if I can suggest a couple things from helping my good friend Mike over the years (Type 1).

Cut out as much white grains as you can - that means no Enertia, no Mt. House. Those are NOT your friend! Beyond the high sodium you want grains that work with your body.

For Mike's meals when I do them I use whole wheat pasta or multi grain pastas, only whole wheat couscous, cooked and dried barley (for this year!), etc, etc. These give him a solid fuel source that slowly is used, no spikes up and down.

Take a look at Mike's advice on www.rainforesttreks.com - he is proof you can do crazy hiking and have good health
