Fiber: what is the difference between soluble and insoluble?

Fiber is divided into two main types, each of which plays a unique role in maintaining the body's health. Soluble fiber turns into a gel-like substance upon contact with water. This process helps slow down digestion, which allows the body to absorb nutrients from consumed food more efficiently.

In addition, this type of dietary fiber effectively binds cholesterol and bile acids in the intestine, promoting their excretion from the body. This helps keep cholesterol levels normal and prevents sharp blood sugar spikes after meals. The main sources of soluble fiber are oatmeal, legumes, apples, citrus fruits, and chia seeds.

Insoluble fiber does not absorb water and is practically indigestible by the human digestive system. Passing in transit through the gastrointestinal tract, it works like a classic broom, increasing stool volume and accelerating intestinal motility. This makes it an indispensable tool for preventing and combating chronic constipation.

To achieve maximum health benefits, it is necessary to combine both types of fiber in your daily diet. Most plant foods contain both varieties, but in different proportions, so a varied menu guarantees obtaining all the necessary benefits for digestion.
