A healthy gut is linked with several benefits, including:

  1. Digestive function, breaking down the food we eat and absorbing nutrients from these foods
  2. Gut comfort, helping to manage bloating
  3. Pathogen protection, which protects against bad bacteria that can cause illness
  4. Immune function, which is your body’s ability to fight illness
  5. Metabolic health, helping all the cells in our bodies function properly to manage weight, cholesterol, blood pressure and blood sugar


What you eat isn’t just for you. It’s also food for the trillions of bacteria in your gut, and these microbes play an important role in digesting food and supporting a strong immune system.

Fibre is great food for our gut microbes, and helps these bacteria thrive. Fruits, vegetables, legumes and whole grains are all delicious sources of fibre, and both soluble and insoluble fibre support these microbes and our overall health.

Then there are naturally fermented foods which contain live bacteria, and there’s more on this below in the “Fermented Foods” section below.

On the other hand, antibiotics, which are important medicine for treating infections and diseases caused by bacteria, work indiscriminately and can affect the diversity and composition of the gut bacteria for as long as two years. When we need to take antibiotics, it could be worthwhile considering these other dietary options for supporting our gut bacteria, and it’s always worth asking your GP for advice about what’s best for you.


The gut and the brain are in constant communication. Here we explain how, though this section gets a bit technical.

The gastrointestinal (GI) tract is the series of organs that that manage the journey everything we eat and drink; food and liquids travel through when they’re swallowed, digested, nutrients absorbed and finally leave the body as waste.

Located within the GI tract is the enteric nervous system, which controls the function of the GI and communicates with the brain via the sympathetic and parasympathetic nervous systems.

The sympathetic nervous system kicks into gear when we face stressful situations, triggering our “fight or flight” response. Then, when we feel we’re out of danger, the parasympathetic nervous system works to calm the body down, sometimes called “rest and digest”.

This is why, when we experience negative emotions the GI tract can speed up or slow down, making the digestive system overly sensitive to bloating, changing the gut microbiota and more. Some great ways to decrease anxiety and mitigate these symptoms include meditation, mindfulness, breathing exercises and yoga. Source: Harvard Health Publishing.

And to top it all off, 90% of serotonin receptors are located in the gut . Serotonin is the chemical in our bodies that helps with sleeping, eating and digesting, and is also considered a natural mood stabiliser. While we can’t diet our way out of depression, some research suggests that eating a healthy, balanced diet may help with our mental health.


Fermented Foods

Fermented foods made with live cultures, such as Kefir, kimchi and sauerkraut, can give your body a dose of live microorganisms crucial to healthy digestion.

And these bacteria are thought to help a multitude of health issues, specifically digestive health.  

Gut specialist Professor Tim Spector was on This Morning in 2019 discussing five things that aren’t great for your gut, and five things that are – and fermented foods, such as Biotiful Dairy Kefir, made the great list. Catch up on the segment here: The truth behind good health? You’ve ‘gut’ to start on the inside!

Kefir is naturally lower in lactose

To make Kefir, Kefir cultures are added to milk and then left to ferment. These Kefir cultures break down the lactose sugars in the milk during this fermentation process, making the Kefir lower in lactose, which is usually the main issue for people’s discomfort when eating or drinking Dairy.

Additionally, Kefir contains enzymes that can help break down the lactose even further.

This means that, even though it’s not entirely lactose-free, our Kefir is naturally lower in lactose and so easier to digest, making it gentler on stomachs. Learn more about Kefir.


Biotiful Kefir contains over 40 strains of gut-friendly cultures, and every serving has billions of them.

Our Original Kefir is simply British milk and Kefir cultures, and to make our flavoured Kefir we add natural fruit puree with no preservatives. There’s no sugar added in our Kefirs, so any sweetness will come from naturally occurring sugars: lactose in the milk, or fructose in the fruit.

All our Kefir products are a source of protein, calcium, vitamins B12 and B2, are vegetarian-friendly and gluten free.

And, of course, we think Biotiful Kefir is delicious. Just ask any of the millions of people who enjoy it.
