What is gut health? How much does science really know. Where can you get more information from?
The interconnected relationship between microbes and humans is an increasing object of research and general public interest. Microbial communities are all around us, on the equipment you are using now to view this article, in your home, place of study or work. Crucially microbes have a significant presence on our skin and inside our bodies, particularly in the digestive tract, with the highest concentrations found in the colon. It should be pointed out the the consumption of fermented foods is linked to a positive, increased richness in gut flora.
Over the last decade advances in technology have led to improved understanding of the collection of bacteria, fungi and archaea (single cell microorganisms) that make up the human microbiome. More importantly there are ongoing attempts to understand the relationship between an individual’s microbiome and their health and wellbeing. In scientific terms the study of the human microbiome is in its infancy, but there are already a wide range of studies linking microbes living in the human gut to health and wellbeing. Elizabeth Bik has written a journal article outlining this general area of research and its challenges and opportunities. I would recommend The Hoops, Hopes, and Hypes of Human Microbiome Research to anyone wishing to get an overview.
The Bik article was published in 2016, and reflects one perspective (albeit a particularly well informed insight). A search on Google Scholar this morning (13th February 2018) for the term microbiome found over 20,000 entries; each entry likely to correspond to a journal article, book/book chapter, or other document. The point being, that this is a rapidly evolving area of enquiry. The types of human experience which appear to correlate with the microbiome is growing and includes; memory, obesity, depression, cancer, Crone’s disease, the immune system and much, much more. However as Elizabeth Bik points out in her article, the fact the certain microbes are correlated with a particular condition does not necessarily mean they cause it or are caused by it.
If you have a particular interest in gut health my advice is to find some good quality journalism as a starting point. If you need something more then go to the best scientific papers available. In my humble opinion, using one article or piece of research rarely builds a full enough picture. If you find out anything interesting feel free to email us or add it to the comments section below.
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!
Welcome to Gut Well Soon, a website committed to sharing knowledge about how fermented vegetables and fruit are able to dramatically improve health and wellbeing.
The site has been launched and we are publishing new articles every week. We to provide information on the subject of fermentation and the respective health benefits. We aim to provide information relevant to absolute beginners as well as highlighting scientific knowledge for those people wishing to know more.
