Fiber is a type of carbohydrate that the body cannot digest. It is found in plant-based foods such as fruits, vegetables, whole grains, nuts, seeds, and legumes. There are two main types of fiber: soluble fiber, which dissolves in water and helps to lower cholesterol and regulate blood sugar levels, and insoluble fiber, which does not dissolve in water and helps to promote regular bowel movements and prevent constipation. Some common sources of fiber include:

1. Fruits: apples, berries, oranges, bananas, pears
2. Vegetables: broccoli, carrots, spinach, Brussels sprouts, sweet potatoes
3. Whole grains: oats, barley, quinoa, brown rice, whole wheat bread
4. Nuts and seeds: almonds, chia seeds, flaxseeds, sunflower seeds, pumpkin seeds
5. Legumes: beans, lentils, chickpeas, peas
