Nutrition tips for long days in the mountains

Hey all, I’m looking for tips/suggestions/your personal favorites for nutrition on long days in the mountains. In my head I’m picturing things like multiple Adirondack 46 or NH 48s (great range traverse or presi traverse). Im no stranger to these types of peaks or fueling for mountain days, but I am trying to hone in on nutrition to better suit myself for longer days, hot days, etc. Usually I’m bringing ample electrolytes, carbs/calories in the shape of snacks (pretzels, peanut butter stuff, crackers, banana chips, fruit snacks), a few protein bars, and sometimes a sandwich or two. For reference I’m a 28y/o M, weigh between 155-160 lbs. I don’t usually bring gels or things of that sort but am open to them,and again just looking for tips or nutrition that has been helpful for you! Thanks and happy trails!
