In general, grains are a great way to start the day, which is why grains for breakfast are so popular. (That said, it’s best to eat whole grains.) Cereal has been a fast-breaking staple for decades, combining taste, convenience and nutrition from which to launch your activity-full day. But cereals high in carbohydrates and sugar and low in fiber are a flimsy launch pad. After the sugar high, you could be left with mid-morning cravings and moodiness. Choose your cereal wisely, aiming for at least 3 grams of fiber per serving. (Five is even better.) Adding milk and fruit is a bonus for your body and brain. Some nutritious cereals include Cheerios, Kix, Wheaties, Total, Kashi, Puffins, Grape Nuts, Quaker Oatmeal Squares, and Cascadian Farms cereals.
