If you're packing peanut butter and jelly in your son's lunch box each day, entice him with another nut. My daughter is a big fan of almond butter — the delicious and nutritious paste that can be substituted for the traditional peanut one on sandwiches, waffles and pancakes. Smeared across apples or halved bananas, it makes for a midday snack that sticks to the stomach and provides protein, fiber and calcium. One sure way to convert your child is to take a trip to your local health store or grocer and let him or her grind a tub of the rich spread.
