The ultimate research on microbiome shows that having a certain bacteria inside your gut may boost the odds of falling ill with bowel cancer. What bacteria should your medical tests NOT indicate?
Lately, researchers tried to find as many links as possible between different types of microbiome and conditions that are ‘eating up’ the current population, such as obesity and anxiety.
The investigation, not yet published, assessed the gut bacteria of 4,000 volunteers of different nationalities in the hope they will find the genetic particularities that give rise to different types of gut microbiome (thought before as existing randomly).
However, they found 13 genes that are responsible for several microbiomes. They moved on to a different trial that included 2,000 participants and tried to understand whether bowel cancer is ‘written’ in the genetic variants linked with gut bacteria. The work paid off, revealing the next insights.
A 2% to 15% increase in the odds of bowel cancer was given by a bacteria called Bacteroidales, after finding it in most patients living with the condition.
It is well-known that genetics are already determined in the first years of life.Therefore, to what extent the lifestyle and diet are able to push cancer forward?
What Can You do About it?
The new path opened the way to many unlocked questions and only time can provide a much-needed steady conclusion. What species of Bacteroidales are involved? Can this bacteria be altered to behave in a different way regarding bowel cancer?
The research represents the first steps to a tremendous journey of knowledge. Prof Tim Spector, an expert in the gut microbiome at King’s College London and author of The Diet Myth added:
The problem is – like genes – there is no one single criminal and there are likely to be hundreds of microbes changing our risk of [bowel] cancer. At present our best defence is to cultivate the most healthy diverse gut communities by eating a wide diversity of plants, full of fibre and polyphenol chemicals.
