There are two main types of fiber: soluble and insoluble, each serving different functions in the body.

• Soluble fiber dissolves in water and can help lower blood cholesterol and glucose levels. Example: oats, beans, and apples.

• Insoluble fiber does not dissolve in water and aids in digestion by adding bulk to stool. Example: whole grains, nuts, and vegetables.

• Both types of fiber are essential for a healthy diet and can be found in various foods.
