Introduction

Fiber rich foods for gut health is more than just a dietary trend it’s a powerful way to support digestion, boost immunity, and improve overall health. A healthy gut plays a central role in keeping your body in balance. From fighting disease to helping you absorb nutrients, your digestive system thrives when fueled with plenty of fiber. In this blog, we’ll explore high fiber foods, their benefits, and how they positively impact your heart, cholesterol, weight, and more.

What is dietary fiber and why is it important?

Dietary fiber is a type of carbohydrate found in plant-based foods that your body can’t digest. Instead of being broken down, fiber moves through your digestive system, helping everything run smoothly. There are two main types:

• Soluble fiber: dissolves in water to form a gel like substance (found in oats, apples, beans)
• Insoluble fiber: adds bulk to stool and helps it pass more quickly (found in whole wheat, vegetables, bran)

Both are essential for gut health and should be part of your daily diet.
