Fibre/Fiber

aka dietary fibre/fiber and roughage.

Always plant derived. Cannot be broken down by digestive enzymes.

Supports health and lowers the risk of several diseases.

Good stuff

Fructans - soluble (inulins)

30g a day

Ideally a split (unknown ratio) between soluble, insoluble and resistant starch.

Considered a carbohydrate.

Prebiotic

Promotes the growth or activity of beneficial microorganisms;

  • apples
  • barley
  • inulin (chicory root) - soluble
  • garlic (which happens to contain inulin)
  • Jerusalem artichoke
  • oats
  • onions
  • seaweed

Probiotic

Soluble (Prebiotics)

Soluble fibre of any kind provides the following potential benefits;

  • food and/or a substrate for your gut bacteria, in particular the beneficial kind such as bifidobacteria and lactobacilli - these bacteria;
    • fend off unwanted pathogens (bad bacteria)
    • prevent infection
    • stimulate your immune system
  • slowing digestion/metabolism (thus slowing glucose/sugar intake when eating simple carbohydrates which in turn may reduce blood glucose/sugar spikes) as well as giving your body more time to absorb other nutrients in the food you eat
  • increasing fullness/satiation (lowering the risk of overeating)
  • reducing cholesterol absorption as it passes through the digestive tract
  • adding bulk to your stools
  • possibly increasing the frequency of your bowel movements
  • lowering your colon cancer risk
  • increasing the effectiveness of and reducing the symptoms of antibiotic use

Increasing Your Intake - Soluble Fibre

  • inulin (prebiotic, a polysaccharide, most often extracted from chicory, FDA approved, increases calcium absorption, promotes the growth of intestinal bacteria, FODMAP, likely to reduce LDL)

Increasing Your Intake - Insoluble Fibre

Further Information

  • Inulin was discovered in 1804 by German scientist Valentin Rose
