We review our first DIY kit on this page, visit these pages for more general information about kefir or links to useful kefir resources
The Mad Millie Kefir Kit from Lakeland was our first experience of DIY kefir. The kit cost £9.99 (at the time of writing) contains everything you need to get started and is a useful first step for beginners.
1 litre glass jar
Stainless steel mixing ball
2 sachets of kefir culture.
On the plus side, instructions are good but simple, the kit contains live cultures that can be used with milk, soy, coconut milk or juice. Everything is pretty good quality and we are still using the equipment even after moving onto kefir grains. The bonus of buying in store at Lakeland is that there’s nearly always someone who can offer some advice or tips. The website also offers a few kefir recipes.
However the cultures can only be reused a couple of times, replacements cultures cost (at the time of writing) £4.99 and produce, this makes the cost of the kefir £1 per litre, not including the cost of the milk or juice. Consider that kefir grains (live cultures) can be purchased for around £5 and have an almost indefinite life.
At the time of writing this product had a 3.5 rating (9 reviews) on the Lakeland website, the replacement cultures were rated as 5/5 (3 reviews). From a beginners perspective this felt like a good purchase, it definitely got us started. The sachets of culture are flexible and don’t have to be used immediately so can be transported or even wrapped up and used as a gift. This flexibility means you pay a premium for the actual product compared to grains.I think this product comes into it’s own as a starter kit and not something for an experienced fermenter. Could be a neat way to get kids involved in taking responsibility of their own healthy diet.
What is fermentation and how is it related to health and well being?
The growing area of study linking human microbiota to health and wellbeing is seeing the development of new learning opportunities. The extent to which microorganisms on our skin and in our bodies meditate our lived experience can be understood through a free Coursera module, Gut check; exploring your microbiome. Maggie and I have completed the first two weeks, I thought potential future students might be interested in hearing more about what this course entails.
This MOOC is produced by the University of Colorado Boulder and the tutors are all linked to the institution; Professor Rob Knight, Dr. Jessica L. Metcalf and Dr. Katherine R. Amato.
As you might expect week one offers an overview of the subject area. Explanations are given for what microbes are in relation to each other (Bacteria, Archaea, Eukaryotes and Viruses) and all living organisms. The role of microbes more generally is explained before looking at how microbes and humans interact. Definitions include the distinction between human microbiota (a community of microbes), and the microbiota (the total genes in the microbiota).
The material highlights a number of interesting microbiome facts including that whilst humans share 99.99% of the same DNA, two humans may only have 10% of their microbiomes in common. This is one of the reasons why gut bacteria is thought to be influential in how we experience life. Although the majority of our microbes live in our gut, there are communities all over us (mouth, skin, vagina). We are born sterile and then communities of microbiota become established at a very early age, changes to these communities happen throughout our lives. The module material clearly illustrates that the microbes we are exposed to have an import role in our lives.
The first week provides a useful introduction to the subject and offers a context for later material. Beyond week 1, the course follows a much stronger academic path. Explaining the science behind the study of microbiota and moving onto subjects such as alpha diversity and ‘fuzzy microbes’. If you’ve tried the MOOC what do you think?
There is a two way communication system between the gut and brain, this is one way that gut microbiota mediate our health.
The growing excitement over the role of gut bacteria is being fuelled, in part, by the realisation of the potential role of the gut – brain axis. The gut-brain axis is the hard wiring between the digestive tract and the brain. That is to say a direct communication link passing information between neural, hormonal and immune systems. A key point to make is that the communication is bi-directional, that means the brain talks to the gut and that the gut talks to the brain. Thus the microbiota (gut bacteria) and metaboloites (small molecules that are the product of metabolism) may be in reciprocal communication with different parts of the brain. While this has a direct and obvious impact on processes related to eating and digesting, there is rising evidence that our gut flora may be significant factors in physical and mental health.
The relationship between emotions and the digestive system is one of which we are intuitively aware. For example, feelings of love often manifest as ‘butterflies’ in the stomach. Engaging in team sports enables you to observe pre-match nerves in both yourself and others; the digestive system often plays an obvious role in how some people deal with tension! There is evidence that stress is a mediating component in gut microbiota, perhaps through increasing or decreasing the optimal conditions for certain types of bacteria to flourish.
New studies are suggesting that individual microbiota may be influential in functions as apparently disparate as memory and fear. It is not known what the basis of the relationship is, where the causality can be found. But that there is a correlation between what is in our gut and how we experience life in terms of mental and physical well being. The take home point is that many of the things we eat and drink are able to positively and negatively influence our health. By taking more interest in what goes into your stomach you might do yourself a power of good.
Outstanding lecture from Prof Simon Carding, how gut bacteria mediates both physical and mental health
Emerging research is demonstrating a profound relationship between the bacteria in our gut and how well we are, our lived experience. In this outstanding lecture Prof. Simon Carding offers insights, new and old into ideas about our gut bacteria. Warning you may see the world a little differently after watching the video!
