Trust Your Gut: The Five Lifestyle Foundations for a Happier Microbiome

Gut health continues to dominate the wellness conversation. After years of growing awareness, the profound connection between the microbiome, immunity, mood, digestion, and overall wellbeing is firmly on the public radar.

"Gut health sits at the core of almost every client case I work with," says Kim Schweiger, a Registered Nutritional Therapist (mBANT, mCNHC). "When the gut is supported, so much else falls into place, from energy and immunity to mood and sleep. It's genuinely exciting to see this conversation entering the mainstream, and I'm pleased to share the five lifestyle foundations I return to again and again in clinical practice."

1. Eat More Fibre and Cut Back on Ultra-Processed Foods

"A diverse, plant-rich diet is one of the best ways to nourish the gut microbiome," Schweiger explains. Fibre plays a dual role in digestive health: soluble fibre feeds beneficial gut bacteria, while insoluble fibre maintains regular bowel movements and supports overall digestive function.

To give your gut a boost, focus on foods rich in gut-friendly fibre such as avocados, kidney beans, artichoke hearts, mushy peas, raspberries, and wholewheat pasta. Concurrently, reducing your intake of ultra-processed foods is key for supporting microbial diversity and maintaining digestive balance.

2. Add Fermented Foods into Your Routine

Fermented foods continue to gain attention for their role in supporting the gut microbiome. Options like live yoghurt, kefir, kombucha, kimchi, sauerkraut, and natto naturally contain beneficial bacteria and nutrients linked to digestive wellbeing.

Natto, a traditional Japanese superfood made from fermented soybeans, has been consumed in Japan for generations and is increasingly appearing in global wellness conversations. Now progressing into Europe and America, natto products, in both raw forms and alternatives like Sonomono Natto Powder Capsules, are introducing the ingredient to a wider audience.

"Fermented foods can contribute vitamins, minerals, fibre, protein, and beneficial compounds that support overall wellbeing," Schweiger explains. "For those who find natto's texture or smell off-putting, a quality natto powder capsule can offer a more accessible way to incorporate this fermented food into a daily routine."

Important Health Note: Anyone taking blood-thinning medication, blood pressure medication, or who has a cardiovascular condition should consult their GP or a registered healthcare professional before taking natto supplements.

3. Prioritise Quality Sleep

Research increasingly highlights a two-way relationship between sleep quality and gut health. Disturbed sleep patterns can negatively affect the gut microbiome, while poor gut health can conversely disrupt your rest.

Most adults require between seven and nine hours of sleep each night. "It’s helpful to set a regular time and routine for going to bed," says Schweiger. "Winding down before bed, away from screens, is really important to let the day go and give your body and mind the signal that it’s safe to switch off and get the restorative sleep we need."

4. Stay Properly Hydrated

Hydration plays a fundamental role in maintaining digestive health and supporting the gut lining.

"Drinking six to eight glasses of water daily can help support nutrient absorption, maintain the intestinal lining, and prevent constipation," says Schweiger. "It’s also advisable to limit alcohol and caffeinated drinks, particularly during warmer weather or if you’re going to be doing a lot of exercise."

5. Move More and Manage Stress

Physical activity and stress management are both closely tied to gut health through the gut-brain axis. Regular movement positively influences the composition of gut microbes while also supporting hormonal balance and digestive transit.

Conversely, chronic stress can elevate cortisol levels, which potentially disrupts digestion and alters the gut microbiome. As interest in preventative health grows, lifestyle habits are proving to be the ultimate tool for everyday health.

"Gut health is never just about food," Schweiger concludes. "Sleep, movement, hydration, and stress all work together to influence how well our digestive system functions."
