How about a mood-boosting and nutritious breakfast to start your day? Blueberries are so small but are packed with so much goodness. They are not too sweet but so flavorful that you can easily end up eating a whole pint without noticing it. Blueberries contain a ton of water and dietary fiber which when consumed on a regular basis can help you maintain a healthy digestive tract. Bananas are also nutrient powerhouses. They are very rich in potassium and can help to keep your blood pressure in check. Yummy!
