Best kefir to buy in the UK for gut health and immunity

The fermented food revolution is showing no signs of slowing down, with foods like kimchi, sauerkraut and kefir regularly flying off local supermarket shelves.

But what exactly is the yoghurt-like substance known as kefir, and how does it benefit our gut health? We chatted with Registered Associate Nutritionist (ANutr) Eli Brecher for some insight into the health benefits of kefir.

What is kefir and why is it good for you?

“Kefir is a fermented milk drink made with cultured kefir grains”, she explains. “It has the tangy taste and a creamy consistency of thin yoghurt and is a rich source of minerals like calcium, phosphorous, B vitamins, and protein”. Kefir is a type of probiotic food, which means it contains live bacteria that benefit our gut health. We know that the health of our gut is linked to so many other systems of the body beyond digestion, from the immune system and mental health to skin, hormones and weight management, so consuming kefir and other probiotic-rich foods can support all these areas.”

How much kefir should the average person drink daily?

“If you’re new to probiotic-rich foods, it’s important to increase your intake gradually to avoid experiencing unwanted digestive symptoms like bloating and gas”, Brecher recommends. “Start slowly, with just one tablespoon per day, and build up over time to around one to two ups a day. As well as kefir, aim to include a variety of other fermented foods and drinks in your diet to increase your intake of probiotics. These include sauerkraut, kimchi, kombucha, miso and live yoghurt”.

She adds, “It’s worth noting that certain people may need to limit their intake of kefir, including people with diabetes (due to the carbohydrate count). While kefir typically contains dairy, it tends to be lower in lactose than other forms of milk, so is often well-tolerated even by those who are lactose intolerant – although it should be avoided entirely by anyone with a dairy allergy, unless made from coconut or soya milk rather than dairy.”

Is it better to drink kefir before or after breakfast?

Brecher reveals, “Drinking kefir at any time of day is beneficial to our health, but it is thought that the ideal time to consume it is on an empty stomach first thing in the morning, in order to ensure that the bacteria remain alive throughout the digestive process. This allows the good bacteria like lactobacillus to settle in the intestinal tract more easily which in turn enables it to crowd out the bad bacteria. However, you can take your kefir any time during the day that works for you.

“Kefir works well when combined with a diet rich in fibre, particularly prebiotic fibre. Prebiotics are the food or the fuel that the probiotic bacteria eat to thrive and multiply in the gut. Prebiotic fibre can be found in foods like onion, garlic, leeks, mushrooms, lentils, oats and green bananas.”

Does kefir help with symptoms of IBS?

The nutritionist says, “The probiotic bacteria in kefir can help restore balance within your gut microbiome, which is the community of trillions of bacteria and other microorganisms that live within our digestive tract. Regular consumption of probiotic foods is associated with reduced digestive concerns, including irritable bowel syndrome (IBS). While kefir can help mitigate IBS symptoms, it’s not a cure and should form part of a healthy, balanced diet, alongside sustainable lifestyle changes such as regular exercise, optimal sleep and stress management techniques like meditation and yoga, which are proven to help with IBS.”

Why are cultured foods so important for gut health?

“Cultured or fermented foods like kefir, sauerkraut and kimchi can all help to increase the diversity of the beneficial bacteria in our gut microbiome. The more diverse our microbiome, the healthier it is, with a wider range of friendly bacteria supporting our health”, she concludes.
