Many of the health benefits of fiber come from the effect it has on your gut flora. This is a name for the millions of bacteria that live in your intestines. These bacteria have a major impact on your health and even how you feel.

Summary: Fiber is crucial to the functioning of your body.

But not all fiber is the same. There are two types of fiber, and each has its own unique health benefits:

  • Soluble fiber
  • Insoluble fiber

Soluble fiber absorbs a lot of moisture and forms a gel-like structure in your stomach and intestines. This stimulates bowel movement and protects your intestinal wall from inflammation.

Soluble fiber also nourishes the good bacteria in your intestines. These bacteria make short-chain fatty acids, which help create the protective layer in your intestinal wall and heal it from damage.

Finally, soluble fibers keep your blood sugar stable and in this way protect you even more against type 2 diabetes.

Soluble fiber can be found mainly in:

  • Legumes
  • Fruit
  • Vegetables
  • Oatmeal

Insoluble fiber is not absorbed into your body. They are the ‘street sweepers’ of your intestines: they keep your intestines clean and active.

Insoluble fiber can be found mainly in:

  • Whole grains
  • Pseudocereals
  • Vegetables
  • Nuts
  • Seeds

Fiber aids in weight loss

Fiber helps you lose excess pounds in three ways [5].

Because they absorb a lot of moisture, they ensure a full feeling, while they provide hardly any or no calories. In addition, fiber keeps your blood sugar stable, which prevents you from craving an unhealthy snack after an hour.

Finally, they stimulate fat burning. Soluble fiber feeds your good gut bacteria, which in return produce short-chain fatty acids. These encourage your body to burn more fat.

Summary: High-fiber foods help you lose weight quickly and healthily without feeling hungry.
