Never use dried foods when bike touring. Are you going to be in remote areas where you will not be able to purchase food on a regular basis? Even if I will be camping several miles away from the nearest town, I prefer to purchase and carry food on a daily basis. A whopping 5 lbs. of food is only about 2.3% of my body weight. When you factor in the weight of the bike, racks, panniers, water and all my other gear, the percentage drops even lower.
