So often, mid-afternoon usually, we hit an energy slump. And often we reach for a candy bar or other sweet to give us a boost. What a wrong choice. A recent study from the University of Cambridge found that it is protein, not sugar, that activates the cells responsible for keeping us awake and burning calories. Suggested items for snacking during that energy slump are low-fat cheese (I like string cheese), a couple slices turkey breast, hard-boiled egg, a handful -approximately 10 - nuts, or a cup of Greek yogurt just to mention a few.
