The first series of videos show backpacking food from the grocery store.
And here are photos of backpacking food items purchased at the grocery store.
I will add, next, videos of simple, but good, easy to prepare meals, utilizing lightweight basic ingredients from the grocery store or the lightweight products from backpacking food suppliers that taste good and are well-adapted to backpacking.
The food shown in these first two videos is for a canoe trip, involving portages of the canoe and equipment from one waterway to another. This is strenuous activity. The food to be consumed reflects the exertion.
Each video shows the food packaged up and ready to go. It is worth seeing the amount of food, and especially, the volume of this food.
Food for a weekend canoe trip
Here, is a canoe trip for a week for two.
I have included this video to illustrate weight is not nearly so important than volume for touring by canoe, or kayak for that matter.
Everything here is compact and packs down to a rather small volume overall.
Food for a 2 person, 8 day canoe trip
As an ultralight or lightweight backpacker, it is not likely you will want to carry more than 2 lbs. of food per day. This is because, you will not be working as hard, you will be conserving your energy, and stopping more often and looking around more.
Next, you will not cook every meal: lunch will likely be eaten on-the-go, and breakfast will not be so elaborate. Some hikers savor a long lunch break. If that is not you, save the more elaborate meal preparations for supper. If you have a long day, first, make a hot drink for the energy to prepare dinner. But have some quick meals that require practically no more effort than removing the wrapper, or, at the most adding-hot-water.
