Hear the words ‘backpacking food,’ and you probably think about stuff in cans: tuna, beans, maybe even Spam, anything that’s already cooked, calorie-dense, and virtually nonperishable. And yet, if you’re going on a backpacking trip for many days or even weeks, canned food actually presents a major logistical issue: it’s heavy.Depending on their body weight, backpackers typically carry around 25-30 pounds worth of supplies on their backs for multi-day trips, according to the site FarOut. That means that every ounce must be accounted for, especially because they’re already packing a tent, sleeping equipment, and items like water filters and camp stoves.
