The Power of fibre ( delicious soup recipe included) by Dr Eden Lurie


Red Lentil Sweet Potato Soup

Let’s talk about fibre.

Fiber is a type of plant based carbohydrate that is not able to be broken down and digested by our body, so it passes all the way to the large intestine where it is broken down and consumed by bacteria living in our colon – the microbiome. Fibre is found in all plant foods such as vegetables, fruit, nuts, seeds, legumes and beans.

Why do we need to eat fibre rich foods?

  1. It helps keep you regular ! Fiber rich foods aid in the procession of food through your intestines by attracting water into the gut, and thus aid in the motility of foods in and out the body.
  2. Stabilises blood sugar levels. It does this by slowing down the rate at which food is emptied out of the stomach and thus regulates and stabilises the availability of broken down natural sugars to the bloodstream.
  3. Lowers cholesterol levels by binding and preventing reuptake into the blood stream, and eliminating cholesterol in the intestines via passage through stool
  4. Feeds our microbiome: enter PREBIOTICS
  5. Reduced risk of colon cancer (!)

What are probiotics and how do eating them help me?

Prebiotics are plant based nutrients, mostly found in fibre rich foods, which are sources of fuel for the bacteria making up the gut, or microbiome. by feeding your microbiome healthy plant sources of fibre and probiotics, it selects for the growth of gut “friendly” bacteria. They also act as food sources for the bacteria, which produce short chain fatty acids (SCFAs) which are fuel sources for the cells of the lining of the large intestine and thus aid in forming a healthy colon.

With all that said, the moral of the story is eat more plants ! This delicious warming recipe is a great example of a meal that will provide lots of fibre and nourish both your soul and your bacteria (ha ha).
