9. Trail mix
Generally, trail mix is a combination of a variety of nuts and other dry ingredients. Traditionally, nuts and dried fruit were the only ingredients. Over time, various trail mix brands have also added chocolate pieces, like M&Ms, to their mixes. Because of this, you’ll need to steer clear of trail mixes that are too high in sodium, sugar, and saturated fats. You can easily toss together your own homemade mix using a variety of nuts and other ingredients while keeping the protein content high and everything else reasonably low.
