🌿🦠 FIBRE 101: WHY YOUR GUT MICROBES NEED IT
When you eat fibre, you're not just feeding yourself...
You're feeding your gut microbes too. 🦠
Unlike carbohydrates that are digested and absorbed higher up in the digestive tract, some types of dietary fibre make their way to the large intestine.
And that's where things get interesting.
Certain gut microbes can ferment these fibres and produce compounds called short-chain fatty acids, including:
🟢 Butyrate
🟢 Acetate
🟢 Propionate
These compounds are involved in maintaining the gut environment and communicating with cells throughout the body.
But here's something important:
FIBRE ISN'T JUST ONE THING.
Different plant foods contain different types and combinations of fibre.
That's one reason I prefer to talk about VARIETY, rather than relying on one fibre supplement or eating the same vegetables every day.
Think:
🫘 Beans, chickpeas + lentils
🌾 Oats + wholegrains
🥦 Vegetables
🍎 Fruit
🥜 Nuts + seeds
🌱 Chia + flaxseed
And don't forget...
💩 Fibre also helps support normal bowel function—something that can become particularly relevant when constipation enters the menopause conversation.
But before you suddenly double your fibre tomorrow...
MORE ISN'T ALWAYS BETTER—ESPECIALLY OVERNIGHT.
If your current intake is low, increasing fibre too quickly can leave some people feeling more bloated or uncomfortable.
My approach?
🌿 Increase gradually
💧 Drink adequate fluid
🌈 Include a variety of plant foods
👂 Pay attention to your individual tolerance
And if persistent bloating, constipation, diarrhoea or abdominal discomfort is an issue, don't simply keep adding more fibre.
That's when we need to ask WHY.
So rather than thinking:
“Which gut-health supplement should I buy?”
Start with:
“What am I feeding my gut microbes?” 🦠🌿
