Many primals consume a lot of nuts, and for good reason. They're simple, energy-dense, and full of healthful fats. Trail mix is a popular snacking recommendation -- but you have to be careful with commercial mixes.
Most commercial trail mixes are made with roasted nuts, whose fats are damaged, and contain added salt or sugar. It can also be hard to find mixes without pusedo-chocolate or other candy pieces, which naturally jack up carb/sugar intake and tend to spur cravings that can result in excessive consumption of otherwise-healthful nuts. Fortunately, it's easy to make your own mix from quality ingredients.
I concocted this Primal Energy Mix specifically for use during extended physical exertion, such as when participating in equestrian endurance racing or long conditioning rides. For snacking on regular days, I make a similar mix without the dried fruit, which adds more carbs than I need for sitting in front of a computer all afternoon.
Primal Energy Mix
2 parts raw almonds
2 parts raw walnuts
1 part raw cashews
1 part coconut flakes, unsweetened
1 part dried fruit, unsweetened and unsulfered (I like figs and home-dried apricots.)
Combine in a large bowl or zip-top storage bag. Store, airtight, in a cool and dark location to protect those precious fats!
