Whether you're just starting a healthy-eating plan or you've been following a healthy diet for years, sticking to the plan can be challenging. To make sure you're getting enough fiber, experiment with new foods and combinations. Add wheat bran to your morning yogurt or smoothie. Add chickpeas or black beans to your favorite soups or salads. Or make nachos with refried black beans, lots of fresh veggies, whole-wheat tortilla chips and salsa.
