Fiber: What do I need to know?
What are dietary fiber ?
The indigestible components of plant food that pass through our digestive tract, absorbing water and giving the stool bulk, are called dietary fiber, also known as roughage or bulk. Fiber cannot be digested and absorbed by the body like other nutrients like lipids, proteins, and carbs. Thus it moves through the digestive system primarily undamaged.
Facts to know about fiber
- In concept, fiber is not a nutrient. Unlike other nutrients, it typically makes its way through the digestive system intact.
- The required quantity of fiber is less than half what an average American eats.
- Constipation can be an adverse effect of overeating fiber.
- Foods might lose some of their fiber content while cooking.
- Fiber can make you feel satiated and full
Benefits of having fiber in the diet
It is crucial for a healthy, balanced diet and is vital in sustaining good health. Here are some reasons why fiber is essential:
Promotes good digestive health
- Fiber facilitates regular bowel movements and aids in the prevention of constipation by giving the stool greater volume. Additionally, it can aid in preventing diverticulitis and hemorrhoids.
Lowers the likelihood of developing chronic disorders
- People who consume adequate fiber have a lower chance of developing a number of chronic diseases, such as heart disease, stroke, diabetes, and some types of cancer.
Helps with weight management
- Foods high in fiber are frequently low in calories and can increase feelings of fullness and satisfaction, making it simpler to control your weight.
- High-fiber foods also take longer to digest, which helps prevent overeating.
Enhances the gut microbiome
- Fiber nourishes the good bacteria in the gut, which may improve immunological performance and general health.
- According to studies, consuming more fiber is linked to living longer.
Types of dietary fiber
Soluble fiber dissolves into water and a gel-like substance, which can hamper the passage of food through the digestive tract.
Benefits of soluble fiber include:
Lowering the amount of cholesterol
- To lower cholesterol levels, soluble fiber can bind to cholesterol in the gut and stop it from entering the bloodstream.
Controlling blood glucose levels
- It can reduce the rate at which glucose is absorbed, regulating blood sugar levels and reducing spikes.
Promoting digestive regularity
- It promotes regular bowel movements and softens feces.
It gives the stool volume and does not break down in the water. Foods including wheat bran, whole grains, nuts, and various fruits and vegetables include this type of fiber. It helps with
- Preventing constipation
- Aiding in digestion
- Maintaining intestinal health.
