What are different types of fiber?

There are two types of fibers, soluble and insoluble fiber. You can get fiber from fruits, vegetables, and grains

  • Soluble fiber: Absorbs the water in the food, turning into a gel-like substance that slows down digestion and softens the stool. This aids in lowering cholesterol and blood sugar regulation 
  • Insoluble fiber:   Doesn’t dissolve in water so it makes stool bulky.  It moves to the digestive system quickly hence                                 helping stool to pass easily, therefore, preventing constipation

What are the symptoms of too much fiber?

Fiber can cause more harm than good if consumed more than 45gms per day. Starting low is the name of the game. This will prevent feeling uncomfortable in your gut. Here are some problems you might incur if you start flooding large amounts of food with a high fiber intake.

  • It can cause intestinal obstruction especially when not drinking enough fluids after consuming fiber.

What happens if you get too little fiber?

As you might already know too much fiber causes digestive problems so is too little of it.  The main culprit of too little fiber is constipation. It is a major digestive issue in modern society, as we eat refined and sugary foods with very little fiber if any.

Half of our plate ideally is supposed to be plant foods but most of us have more animal protein than from plants.  Plants provide more fiber which that gives minerals and vitamins for our gut to function optimally.  These increase our chances of living longer, healthier, and happier lives.

Does fiber make you poop hard or soft stools? 

Fiber makes the stool more solid due to the nature of having the capability of absorbing water. 

As a result, it makes the poop bulkier and softer so it can pass with ease. A stool can become harder when the fiber is consumed and not drinking enough fluids.

What are the consequences of low fiber intake?

  • Constipation, bloating
  • feeling hunger after meals
  • Alteration in blood sugars
  • Low energy/fatigue
  • Increase in cholesterol
  • Colorectal cancer

How does fiber affect diseases?

Low or deficiency of fiber can affect overall health. Fiber supports gut health if your gut health is compromised

then diseases are inevitable. Not consuming enough fiber will yield irregular bowel movements, constipation, an increase

in blood sugars, and high cholesterol. Therefore, increases the chances of getting  diseases such as obesity, diabetes, heart disease, and digestive conditions like colon cancer and diverticulosis

Dennis Burkitt known as the fibre man linked these groups of diseases to his hypothesis simply due to a deficiency in fiber intake.
