Between the mince pies, late nights, fizz-filled celebrations and irregular eating patterns, the festive season can be joyful – but it can also challenge your gut health. Many people report feeling more bloated or sluggish, but it doesn’t have to be this way. Here are five simple, science-backed tips written by Dr Megan Rossi (PhD, RD), to help your gut thrive through the season, without missing out on any festive fun.

1. Keep your gut microbes on a rhythm
Did you know your gut microbiome has its own circadian rhythm, just like you? With party season in full swing, that rhythm can be thrown off not only by disrupted sleep but also by late-night eating, affecting digestion and even your immune defences. Where you can, try to keep mealtimes consistent, and if you’re planning a big celebratory meal, don’t fall into the trap of skipping earlier meals to “save up”. Instead, stick to your normal eating pattern and add some extra gut-nourishing foods to keep your microbes fed and happy — this can also help prevent binging and those unwanted gut symptoms later in the day.
It’s also worth aiming to finish eating at least three hours before bed to allow food to move through your stomach. You’re more likely to suffer from acid reflux if this doesn’t happen, as leftover food can put pressure on the valve that separates your stomach from your oesophagus. As well as being uncomfortable, this can disrupt your sleep quality (research shows that just two days of disrupted sleep can negatively affect your gut microbes)
And if you want some easy, delicious ways to build your fibre tolerance, keep an eye out for the two new Mindful Chef recipes I’ve co-created with your gut in mind, arriving on the menu from 21st December 2025. Both provide 1/3 of your daily fibre and are packed with diverse plant ingredients to gently support your gut. Scroll to the bottom of the page to see the recipes.
2. Go slow and steady on the festive fibres
Brussels sprouts, asparagus and other festive greens all make great additions to your plate at this time of year, rich in fibre and prebiotics that feed the beneficial bacteria in your gut. But if your gut isn’t yet what I call “fibre fit” (able to digest fibre-rich foods comfortably), a sudden increase in these veggies can cause uncomfortable gut symptoms like bloating or excess gas. That doesn’t mean you should avoid them completely. Instead, start small—¼ or ½ a portion per meal—and increase gradually over the festive season.
3. Move and connect
Those family walks and long catch-ups over coffee offer more than just festive cheer. Gentle movement helps stimulate digestion, while quality time with loved ones supports the gut:brain connection by lowering stress and calming the enteric nervous system. Emerging evidence even suggests that socialising may benefit the microbiome itself, as the science shows we share microbes with the people we spend the most time with. So, connecting with others this season may help your gut health in more ways than one.
4. Protect your gut barrier
Reaching for that extra glass of fizz? Alcohol can temporarily disrupt the gut barrier, often referred to as a ‘leaky gut’, making it easier for unwanted toxins and bacteria to pass through and trigger inflammation. While this effect is usually temporary, the gut’s ability to repair itself slows with age, so supporting it during periods of indulgence becomes even more important.
One way to do this is through fibre-rich, gut-loving foods like beans. They are easy to add to soups, salads or sides, and packed with plant-based protein, fibre and prebiotics, which is why they’re always a go-to in my house. The prebiotics act as a fertiliser for your gut bacteria, helping them produce short-chain fatty acids that help to strengthen the gut lining and support overall gut health (plus your metabolism).
But as well as getting your fibre fix, if you are drinking alcohol, you might also want to consider alternating each alcoholic beverage with a soft option such as kombucha, sparkling water with frozen mixed berries or a homemade pear and ginger spritz to help reduce stress on your gut.
5. Get specific with your supplements
We’ve already talked about how the festive season can put extra strain on the gut, but this can have a knock-on effect on your immune health too, with 70% of your immune system living there. In these situations, a targeted probiotic can help. For example, the combination of Lactobacillus rhamnosus, LGG and Bifidobacterium, BB-12 — the exact formulation you’ll find in SMART STRAINS (available to shop when logged into your Mindful Chef account) for your immune system — has been shown in clinical trials to reduce the severity of colds and flu by over 30% and shorten their duration by around two days compared to placebo. Start taking them ahead of the winter cold and flu wave (or before extra visitors descend on you).
