Take a look at the nutrition label on a freeze-dried backpacking meal, and you might be surprised by how much sodium it contains. Some meals pack more than 1,500 mg into a single pouch, roughly two-thirds of the recommended daily limit of 2,300 mg for most adults<\/a>. That\u2019s a lot for one dinner, but when you\u2019re spending hours sweating your way up steep climbs, you\u2019re also losing sodium along with water.<\/p>\n Sodium helps regulate fluid balance and supports normal nerve and muscle function. Yet there\u2019s a contradiction in how you might think about it on the trail: you question the sodium in your freeze-dried dinner while adding electrolyte powder to your water bottle and snacking on pretzels, jerky, and cheese.<\/p>\n So, are you consuming too much sodium or not enough? The answer depends on what\u2019s already in your food, how much you\u2019re sweating, and how you\u2019re replacing fluids.<\/p>\n You can pack nearly identical amounts of food and end up with dramatically different sodium intakes. I compared two realistic days of backpacking food, each containing commercial meals, protein bars, snacks, and other familiar trail staples. Both provide roughly 3,150 calories and weigh about 23 ounces dry, yet one contains 5,465 mg of sodium while the other contains just 1,975 mg.<\/p>\nTwo Food Bags, One Big Sodium Difference<\/b><\/h2>\n
