Embrace whole-grain carbs Gone are the days when carbohydrates were poo-pooed. Today, we applaud the variety that is whole grain, like brown rice or whole wheat pasta. Unlike the white types out there (bread, sugar, potatoes, pasta), whole grain carbs can actually raise serotonin -- which you need to help avoid panic, anxiety and depression. These foods also boast folate, which is linked to an increase in happiness and joy. Field's tip: Make yourself an open-faced sandwich with vitamin-rich veggies and cheese (to add protein and calcium) as an afternoon snack.
