Kefir – what’s it all about?

You may have heard a lot of talk recently about “kefir.”

But what is kefir, and why is it getting so much attention in the media these days? 

Kefir is a probiotic fermented milk drink, ideally made from goat’s milk. It’s a bit like drinking yogurt, but much stronger and more beneficial for you. 

What’s a probiotic? 

A probiotic contains live bacteria that are beneficial for your gut microbiome.1 Over time, exposure to stress, sugar, medications and chemicals can deplete the trillions of living bacteria inside your large intestine. Kefir puts the good “gut bugs” back into your gut microbiome, restoring it to healthy diversity.2

Why does it matter? 

Your gut microbiome is incredibly important, as it helps regulate the health of your brain, heart, digestive system and joints. 70% of your immune system also sits inside your gut, so a healthy gut will help you to fight off infectious colds and viruses.3

What’s so great about kefir? 

Unlike manufactured probiotics, kefir contains a natural synergy of many different strains of bacteria, all working together to boost the good bugs and suppress the pathogens inside your system. Because it’s all-natural and chemical-free, kefir is the best way to improve the living ecosystem inside your gut.  

What’s the best place to get kefir?

What do Chuckling Goat customers say?

There are kefirs and then there is Chuckling Goat. This is the best of the lot and it is underpinned by science. The company is thoughtful, environmentally conscious and cares about their customers. Everyone that I have spoken to who has tried it, thinks so too!4

What’s the difference between kefir and yogurt? 

Kefir contains “non-transient” bacteria, which have been shown to survive the digestive tract to have a positive effect on your gut health. The bacteria in yogurt is “transient,” which means that it gets killed off during the digestive process, and doesn’t survive long enough to do any real good inside your system.5

Where’s the proof? 

Dr Michael Mosley in his BBC2 television show Trust Me I’m A Doctor, performed NHS studies proving that kefir is the most effective of all probiotic foods available today, and does the most to improve your gut health.6

What kind of kefir is best? 

Dr Mosley also demonstrated that the best kefir is: 

  1. Traditionally made, with real kefir grains7
  2. Live and unpasteurised 
  3. Pure, unflavoured and unsweetened. Sugar and sweeteners kill off the good bugs, and do your gut more harm than good. 

Why is goats milk better than cow’s milk for kefir? 

Cow’s milk is allergenic because it contains the A1 casein, which causes an allergic response in many adults. Goats milk contains the A2 casein, and so is considered non-allergenic and easily tolerated by most people.8

Can kefir help protect you from viruses?

New science published in the Journal of Biomedicine and Pharmacotherapy, January 2021, demonstrates that kefir can suppress viral activity by modulating immune-system responses and/or causing disruption of viral adhesion. The study authors state: “Using kefir (and its byproducts) as an inhibitor of expression of proinflammatory cytokines in COVID-19 patients could be a viable policy.”10

  1. Hi Shann, I was a subscriber until we left in December to live in the Açores
    Getting goat milk a bit tricky here, mainly used for cheese, I have started getting whole cow milk starting to make yoghurt, I have a milk kefir culture to use, I am also starting to make water kefir
    I found a kefir in the supermarket but imported from Spain
    Your thoughts on what I can make here?
    BTW liked the blog

    1. Hi David – I really don’t recommend regular cows milk for human consumption, it’s too allergenic. If you can’t source goats milk, try buffalo, camel or sheeps milk. Sometimes you can find A2 cow’s milk, which comes from Jersey or Guernsey cows, and lacks the allergenic A1 casein. Good luck!

  2. Good afternoon

    Can you advise me of the best time to take your daily glass of kefir please.

    1. Hi Sandra – Best to take your kefir first thing in the morning, on an empty stomach! This allows the beneficial bacteria to adhere to the intestinal lining.

  3. I have only been taking kefir for 10 days and I can already feel a great improvement. My acid has reduced and my gut feels so much better. I am taking the highest dose of medication from the Doctor and Consultant for my stomach problems . I am so impressed that hopefully I will be able in time to start reducing this medication which would be amazing. I will keep you posted.

    1. Hi Maralyn – Great to hear that you are feeling the benefits of the kefir after just 10 days! If the medication that you’re currently taking is a PPI, or Proton Pump Inhibitor, I do encourage you to try to wean yourself off as soon as possible. Recent studies regarding the long-term use of PPI medications have noted potential adverse effects, including risk of fractures, pneumonia, Clostridium difficile diarrhea, hypomagnesemia, vitamin B12 deficiency, chronic kidney disease, and dementia.,chronic%20kidney%20disease%2C%20and%20dementia.

  4. I would like to try the kefir, but I would like to take it every other day to see how I get on. Any problems with that ?
    Thank you
    Alison Porter

    1. Hi Alison – Consistency is key when it comes to your microbiome. Better to take a smaller dose every day, than skip days.
