What are Prebiotics and why you should care

Prebiotics are indigestible fibres that feed the good bacteria in your gut. 

Many of us are familiar with probiotics and know these friendly bacteria are good for our gut health. But, what about keeping these ‘good bugs’ thriving? That’s where prebiotics come into play. In this article we take a closer look at what prebiotics are, their benefits and what foods to include in your diet so you get enough of them.

What are Prebiotics?

This indigestible fibre is found in fibre-rich foods such as fruits, vegetables and whole grains. However, prebiotics are a specific type of indigestible fibre that bypass your small intestine and heads to your colon where they are fermented by the bacteria in your gut. It is here they can be metabolized by the probiotics as fuel. 

The Power of Prebiotics and Probiotics

The powerful combination of prebiotics and probiotics promotes optimal body function. Probiotics play an important role in many areas including helping to break down food, absorb nutrients, regulate blood sugar control and support digestive efficiency, immune function and brain function. Prebiotics play the important role of fuelling probiotics, so they can thrive and do these jobs efficiently. 

Benefits of Prebiotics

Prebiotics support probiotics which supports your health in numerous ways. Dr. Amy Meyers, a functional medicine specialist, clearly explains the importance of a healthy gut.

More specifically, here are the health benefits a healthy gut may provide:

  • An efficient and well-functioning digestion system
  • Strong immune function
  • The body’s ability to absorb essential nutrients such as calcium, in turn supporting bone health 
  • The ‘good’ bacteria are there to fight the growth of any ‘bad’ bacteria, reducing the risk of infections
  • Increase the production of short chain fatty acids, which fight bad bacteria and increase production of immune-boosting white blood cells
  • Activate production of Gut Associated Lymphoid Tissue (GALT), a component of the gut wall that protects the digestive tract from bacteria that can be on the food we consume
  • Fuels the good bacteria which powers the colon, a major health organ 
  • Supports the body in processing carbohydrates, which in turn supports digestion and metabolism, resulting in natural and healthy weight control 
  • Aids in production of the hormones that control appetite and anxiety
  • Assists in balancing your hormones, boosting your mood, and relieving stress
  • Can help relieve allergy and inflammatory response

Prebiotic Rich Foods

Eating a well-balanced diet, rich in fruits and vegetables is the best way to naturally provide your body with prebiotics. It’s important to be aware that not all foods containing fibre are prebiotic.  The following list of foods contain high levels of prebiotic fibre.
