Try out these 4 great snacks! Green tea + handful of walnuts or almonds "Green tea has less caffeine than coffee, but like coffee, it helps boost dopamine in the brain. I like the nutrient density and jolt of fatty calories that comes with the nuts. Caramel rice crackers + tea latte "Sometimes, having a little caffeine along with carbohydrates is a marvelous mood and energy booster. That's why the British afternoon tea makes so much sense! Hummus + baby carrots "When you're tense, chewing is a real stress reliever -- kind of like giving a dog rawhide. Carrots are crunchy and satisfy that sweet craving, and hummus is salty and provides carbs -- and a hit of happiness." Water + apple + peanut butter "Hydration is important -- if you get even a little dehydrated, you'll feel the slump. The fiber from the apple makes you feel full longer, and the protein in peanut butter prevents a blood-sugar spike, keeping you on an even keel."
