The past five years have truly transformed our understanding of gut health, and I am passionate about helping others achieve better health outcomes through nutrition. As a food scientist and nutritionist, I’ve dedicated my career to blending culinary enjoyment with scientifically backed health benefits. Incorporating Top 10 Gut Healthy Foods into your daily diet is one of the most effective ways to boost your well-being, and I’m excited to share my personal favourites with you. 

Each food I’ve selected not only improves gut health but also delivers a range of additional benefits—because, in my world, food must work hard and be smart. These Top 10 Gut Healthy Foods will help nourish your microbiome, support digestion, and contribute to a healthier, happier you. 

1. Garlic

Garlic is a powerhouse when it comes to gut health, not only is it a staple in my kitchen, I am so convinced of garlic’s super powers that I’ve written a book about it called The Garlic Story. The book a testimony of the many health benefits of garlic and the many beautiful ways in which it can be enjoyed. As a natural prebiotic, garlic fuels the growth of beneficial gut bacteria like Lactobacillus and Bifidobacterium. It’s also rich in allicin, which has anti-inflammatory and antimicrobial properties. 

• Nutritional Breakdown: High in vitamins B6 and C, manganese, and selenium. 

• Why It’s Great: Enhances gut flora, reduces inflammation, and supports immunity. 

“The Garlic Story.”  Is available to purchase here on Amazon or at The cooking Academy book shop.

2. Onions

From the same family as garlic, onions are another fantastic prebiotic food. They contain inulin and fructooligosaccharides (FOS), which stimulate the growth of good bacteria in the gut. I cook with onion all the time – if not white onions in sauces or curries then red onions.  I particularly like finely diced red onion with avocado, cucumbers and tomatoes in a salad or fresh mangoes in the summer. 

• Nutritional Breakdown: Packed with vitamin C, B vitamins, and antioxidants. 

• Why It’s Great: Supports digestion, boosts immunity, and helps regulate blood sugar. 

Adding onions to your meals is a simple way to include one of the Top 10 Gut Healthy Foods in your diet. 

3. Flaxseed (Linseed)

Flaxseed is a nutritional superstar in my diet. It’s rich in dietary fibre and omega-3 fatty acids, which are essential for gut health. I add ground flaxseed to my smoothies, oats, and baking. I frequently use it as a thickening agent which is why its also used as an egg replacement often in a vegan diet.  

• Nutritional Breakdown: High in fibre, lignans, and omega-3s. 

• Why It’s Great: Promotes bowel regularity, reduces inflammation, and supports heart health. 

Flaxseed is a versatile member of the Top 10 Gut Healthy Foods. 

4. Kefir Yoghurt

I swear by a daily shot of kefir yoghurt to keep my gut bacteria topped up. Kefir is a fermented milk drink loaded with probiotics, particularly Lactobacillus kefiri and Bifidobacterium. 

• Nutritional Breakdown: Rich in calcium, protein, and probiotics. 

• Why It’s Great: Improves digestion, boosts immunity, and supports bone health. 

Including kefir in your routine is a delicious way to benefit from one of the Top 10 Gut Healthy Foods. 

5. Olives

Olives are another favourite of mine, and they deliver multiple health benefits. They are naturally fermented, providing a source of probiotics, and they’re packed with healthy fats. I use them regularly to make a pasta sauce, as the base with tomatoes, it really bring a rich umami flavour like no other.  I also add a drop of balsamic vinegar to heighten the flavour with some sharpness.   

• Nutritional Breakdown: High in monounsaturated fats, vitamin E, and polyphenols. 

• Why It’s Great: Supports gut health, reduces inflammation, and promotes heart health. 

6. Almonds

I rely on almonds for snacking, smoothies, and baking. These versatile nuts are high in fibre and polyphenols, which act as prebiotics to support gut bacteria. 

• Nutritional Breakdown: Rich in vitamin E, fibre, and healthy fats. 

• Why It’s Great: Supports digestion, heart health, and skin health. 

Almonds are a crunchy addition to the Top 10 Gut Healthy Foods list. 

7. Oats

Oats are a staple in my morning routine. Whether in granola, Bircher muesli, or cookies with ground flaxseed, oats provide beta-glucan, a type of soluble fibre that nourishes good gut bacteria.  

• Nutritional Breakdown: High in fibre, manganese, and phosphorus. 

• Why It’s Great: Promotes satiety, supports heart health, and improves gut health. 

8. Miso

As a vegetarian, miso is my go-to for adding umami flavour and gut-healthy probiotics. It’s a fermented paste made from soybeans, rich in beneficial bacteria. I use miso paste on mushrooms and aubergines and grill or bake them. 

• Nutritional Breakdown: Contains protein, probiotics, and vitamins like K and B12. 

• Why It’s Great: Supports digestion, boosts immunity, and adds depth to dishes. 

Miso is one of the most flavourful Top 10 Gut Healthy Foods. 

9. Mushrooms

Mushrooms are a natural source of prebiotics, particularly beta-glucans. I often cook with shiitake and oyster mushrooms, which are versatile and packed with nutrients. 

• Nutritional Breakdown: High in fibre, selenium, and vitamin D. 

• Why It’s Great: Supports immune function, promotes gut health, and reduces inflammation.

10. Sprouted Beans

I grew up eating sprouted mung beans, a traditional dish that’s rich in nutrients. Modern alternatives like bean sprouts are easy to incorporate into stir-fries and salads. 

• Nutritional Breakdown: High in fibre, protein, and vitamins C and K. 

• Why It’s Great: Enhances digestion, supports weight management, and boosts energy levels.
