Fiber foods are intricate carbohydrates that are quite different from other carbohydrates that are digested to give fuel to the body in form of glucose. However, fiber is never digested by the human body. It is also known as roughage, it is generally found only in plants. It is the only part of the plant that is never digested and is found in the walls of the plant cells.
The major function of fiber foods is to make sure the digestive system is functioning properly and healthily. It speeds up and aids the excretion of toxins and wastes from the human body. This prevents the wastes from accumulating in the bowel or intestines for too long. The accumulation of toxins and wastes in the body can lead to various diseases.
Types of Fiber
To answer the question what is fiber? It is important for you to understand the two main types of fiber:
- Insoluble Fiber and
- Soluble Fiber.
Insoluble fiber just passes through the human body without any change along with the digested food until it reaches the large intestines. This type promotes the growth of particular bacteria, which ferments the food and makes it bulky and soft.
On the other hand, soluble fiber absorbs the water in the intestines. This softens the stool and aids waste removal through the body quickly. Recent studies show that this type of fiber reduces the cholesterol level in the blood. However, it slows down digestion resulting in the sudden release of energy. This explains why it is good for diabetic patients.
