Although it’s often a subject shunned by polite society, what happens in your bowels is becoming increasingly an object of open discussion. The growth of interest in fermentation and gut bacteria is linked to an awareness of a relationship between improved health and how what we eat is processed in our gut. It goes without saying that we are what we eat. This maxim reflects the traditional understanding that the quality of the food we consume is a factor in our health. But science is increasingly demonstrating that the nutrients contained in our meals rely on a range of microbes to extract the maximum benefit from them.
While a discussion centered on healthy eating is normally something that can be sanitized, with the microbiome (the human microbial population), sooner or later human waste has to be discussed. What happens all through the intestinal tract including the colon has a key part to play in human health. Often the state of your own faecal matter (poo) can be a good indicator of what’s going on inside you. If you have a healthy diet and your food is being digested properly, the chances are you that you have a good quality and quantity of helpful bacteria in your system. There are a number of conditions that lead to the loss of a significant proportion of useful gut bacteria, these include the overuse of antibiotics.
Faecal Microbial Transplant (FMT) is a treatment used in a limited number of clinical cases, but its application demonstrates just how crucial gut bacteria is. As its name suggests, FMT is the transplanting of bacteria and yeasts from a person with a healthy digestive function into a person that has a significant lack of the necessary microbes. When one of the world’s best triathletes, Lesley Paterson contracted Lyme Disease, she turned to FMT as an alternative solution. Lyme Disease often leads to tiredness and low energy in those infected, and antibiotics are often prescribed as part of the treatment. Antibiotics have a number of possible side effects including massive reduction in gut bacteria, often further lowering the body’s natural resistance further. In some cases FMT is thought to offer an effective yet inexpensive solution with few negative side effects. Lesley Paterson’s story can be found on the BBC website.
