Sep 4, 2025 22m 28s 17 insights
Twenty years ago, very few scientists even knew about something called the gut microbiome. Now, with over 70,000 research papers published on the subject, this complex ecosystem, home to trillions of microorganisms, is recognised as a key factor in our physical and mental wellbeing. Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests. Today’s clip is from episode 508 of the podcast with microbiome scientist and researcher at King’s College London, Dr Emily Leeming. We now know that our gut health plays a crucial role in everything from our immune system and our ability to respond to stress, to our skin and even our mental wellbeing. In this clip, Emily shares some of the latest science along with some simple, practical tips for building more gut-friendly foods into your diet. Emily is someone who is highly knowledgeable and passionate about helping us all improve the health of our guts. Her message is clear: nurturing our gut microbiome is not about following rigid rules – it’s about understanding this remarkable ecosystem and working with it, not against it.

Actionable Insights

1. Prioritize Minimally Processed Whole Foods

Follow general dietary principles by eating foods that are minimally processed, as close to their natural form as possible, and avoid excess added sugar to support overall health.

2. Personalize Your Diet

Recognize that there is no single perfect diet for everyone; instead, personalize your eating approach by listening to your body’s wisdom, including hunger and fullness levels, to understand what works best for you.

3. Make Small, Consistent Changes

Focus on making small, regular dietary changes that you can easily keep up with, enjoy, and find delicious, as these consistent actions are the most impactful for your health.

4. Increase Daily Fiber Intake

Aim to increase your daily fiber intake, as it is a forgotten nutrient that feeds your gut microbiome, leading to the production of anti-inflammatory short-chain fatty acids and supporting gut barrier health.

5. Incorporate BGBGs Daily

Add ‘BGBGs’ (beans, greens, berries, grains, and nuts and seeds) to your essential shopping list and aim to include them as everyday or most-day foods to boost your fiber intake and feed your gut microbes.

6. Eat a Rainbow of Polyphenol-Rich Foods

Consume a variety of different colored fruits and vegetables to ensure a diverse intake of polyphenols, which are compounds that give plants their color and feed your gut microbes, supporting gut microbiome health.

7. Choose Affordable Polyphenol Sources

Incorporate affordable, polyphenol-rich foods like black beans, which contain significantly more polyphenols than some expensive alternatives like wild blueberries, to support your gut health without overspending.

8. Add Avocado for Fiber

Include avocado in your diet, as one avocado contains approximately eight grams of fiber, contributing significantly to your daily fiber goals.

9. Enjoy Dark Chocolate for Fiber

Consume dark chocolate, ideally 70% cocoa or above, as it provides about 11 grams of fiber per 100 grams and can be a delicious way to boost your fiber intake.

10. Eat Rye Pumpernickel Bread

Incorporate rye pumpernickel bread into your diet, as one slice can provide seven grams of fiber, helping you reach your daily fiber target, especially at breakfast.

11. Keep Nuts and Seeds Accessible

Store a jar of high-fiber nuts and seeds (like chia seeds, flax seeds, or dried coconut flakes) by your kettle or in a visible spot to prompt you to have them as snacks or sprinkle them onto breakfast or salads.

12. Simplify Gut Health with Meal Additions

Make simple, practical changes to support gut health, such as adding onions and garlic to stews or soups, or sprinkling extra herbs, nuts, and seeds onto your lunch, as these small additions make a big impact.
