Carbs. They’re always in the spotlight—and often slammed. One minute they’re your best friend for energy, the next they’re the villain behind your bloating, weight gain, and sugar cravings. So what about carbs and gut health? How do they actually affect your gut?
Let’s break it down 👇
First things first: Why do we even need carbs?
Carbs are your body’s preferred fuel source. Most of them get broken down into glucose, which fuels your cells and powers you through your day. Your body even stores extra carbs as glycogen to use later (like during exercise or overnight fasting).
BUT—it’s not as simple as “carbs are good” or “carbs are bad.”
Because not all carbs are created equal.
⚡ Fast Carbs = Fast Trouble (Especially for Your Gut)
These are the refined, processed carbs—stripped of fibre and nutrients, and known for wreaking havoc on your blood sugar and digestion.
Here’s why they’re gut-unfriendly:
-
They feed the wrong kind of gut bugs, disrupting your microbiome
-
They cause blood sugar spikes, leading to energy crashes and cravings
-
They create a pro-inflammatory environment in the gut
If you’re worried about your gut health, I’d highly recommend downloading my online course The Ultimate Gut Health Programme to help support your digestive system, whilst avoiding triggering symptoms.
It’d be impossible to include all you need to know in one blog, but the programme will have all you need to know to ensure you’re soothing your digestive system, whilst eating delicious and filling foods.
👎 Carbs and gut health: Carbs to cut back on:
-
Fizzy drinks
-
Fruit juice (yes, even the “natural” ones)
-
Pastries & cakes
-
White bread, pasta, rice
-
Sugary cereals
If it’s white, fluffy, and packaged—it’s probably not doing your gut (or waistline) any favours.
🥦 Smart Carbs = Happy Gut
Whole carbs—aka carbs that still have their fibre and nutrients intact—can actually support gut health. These feed your good bacteria, keep your digestion regular, and help reduce inflammation.
👍 Gut-loving carbs to load up on:
-
Colourful veg
-
Whole fruits (not juices!)
-
Legumes (beans, lentils, chickpeas)
-
Sweet potatoes & potatoes (skin on!)
-
Wholegrains like brown rice, oats, and quinoa
Bonus tip: Pair your carbs with protein and healthy fats to keep your blood sugar stable and your gut bugs happy.
🧬 Carbs and gut health – the microbiome, the link you can’t ignore
Recent studies show that very low-carb diets can reduce gut bacterial diversity. That means fewer good bugs, less short-chain fatty acid production (especially butyrate), and a less resilient gut overall.
So if you’ve cut carbs drastically and your digestion’s gone downhill—bloating, constipation, food intolerances—it might be time to rethink.
Once your gut is in a better place, a Mediterranean-style diet with plenty of fibre-rich carbs is a great long-term strategy.
❓Should you eat fewer carbs?
That depends.
✅ If your energy is stable, your digestion is happy, and your weight is where you want it—great! Keep going.
⚠️ But if you’re constantly tired, struggling with cravings, bloating, or your gut is a mess—it’s worth reviewing your carb intake (and which carbs you’re eating).
🔥 Final Thoughts
You don’t need to fear carbs. But you do need to get smart about them.
When it comes to carbs and gut health, the goal isn’t low carb, it’s smart carb. Focus on fibre-rich, whole food carbs that nourish your gut bacteria and support balanced blood sugar.
And remember—there’s no one-size-fits-all. Your ideal carb intake depends on your age, activity levels, hormones, and gut health.
