The Not-Sad Smoothie
Food Mood Girl Lindsey Smith turns to nourishing ingredients (such as leafy vegetables) instead of processed foods to shake herself out of a funk—and she shares dozens of her satisfying recipes in her new book Eat Your Feelings: The Food Mood Girl's Guide to Transforming Your Emotional Eating. Science backs this up: A study published in the journal Psychosomatic Medicine found that optimism was associated with greater carotenoid concentrations—and you'd be hard-pressed to find a food with more carotenoids (such as lutein and beta-carotene) than kale. Smith's tasty smoothie contains a big handful of the star ingredient together with blueberries and cacao (minimally processed chocolate). Blend them together with water or almond milk and you've got a delicious morning pick-me-up.
