Q

What are the complex carbohydrates (polysaccharides)

A
  • Starches – found in foods such as bread, rice, pasta, grains, vegetables, legumes etc
  • Cellulose – the structural material plants (found in plant walls), provides dietary fibre

Complex carbohydrates:

  • Retain their rich nutrients
  • Are digested more slowly, promoting satiety and help to keep blood glucose in balance

Q

What are the benefits of fibre for the microbiome?

A

Feeds the microflora, resulting in numerous health benefits
Fermentation of some fibre in colon by healthy bacteria produce short chain fatty acids
= fuel source for colon cells
= reduces local inflammation
= effects throughout whole body such as blood glucose control, cholesterol moderation
