Probiotics have many benefits, but could these bacteria also help prevent serious diseases as cancer from developing?
Those diagnosed with cancer often experience extreme anxiety and stress. This is because such a diagnosis is associated with severe sickness, gloominess and death. But also because conventional treatment is often expensive, complicated, and associated with side effects.
However, new, simpler strategies are emerging. For example, recent research suggest using microorganisms—probiotic bacteria.
Probiotics for serious disease
The human body is covered in trillions of microorganisms, both on the outside and the inside. These organisms colonize the digestive tract, the skin, and mouth. Each person has a unique colony that has developed since birth and is shaped by diet, lifestyle, and other factors.
The gut contains strains of the Lactobacillus family, which are also used to produce fermented foods like yogurt, sauerkraut, and fermented vegetables. Lactobacillus species are also included in many probiotic supplements.
In a 2016 UCLA study, Lactobacillus johnsonii 456 proved to reduce gene damage and greatly reduce inflammation in mice. Much research confirms that inflammation plays a major role in the development of cancer, heart disease, and autoimmune diseases. Therefore, the UCLA finding is intriguing.
The probiotic bacteria given to mice stimulated them to produce certain metabolites known to prevent cancer. For example lymphoma that originates in the immune system, slowed down considerably in mice fed with probiotic bacteria. The mice also lived longer, had less DNA damage, lower inflammation, and an improved metabolism. The researchers stated: “Remarkably, our findings suggest that composition of the gut microbiota influences and alters central carbon metabolism in a genotype-independent manner.”
The researchers continued: “Together, these findings lend credence to the notion that manipulating microbial composition could be used as an effective strategy to prevent or alleviate cancer susceptibility. In the future, it is our hope that the use of probiotics would be a potential chemopreventive for normal humans, while the same type of microbiota would decrease tumour incidence in cancer susceptible populations.”
As there are strong indications that probiotics works well in animals one can wonder if humans would respond in a similar manner to probiotic treatment?
Probiotics and disease?
This research indicates that in the future it might be possible to use probiotics more effectively to prevent serious disease. How?
A doctor can analyze the bacteria residing in a person’s gut and determine which specific bacteria strains are needed. After this, it’s fairly easy to add the gut bacteria that are involved in reducing this individual’s risk of developing serious disease. But already now we can do something.
- A high-quality probiotic supplement with a wide range of bacteria.
- Consume fermented food as kefir, yogurt, sauerkraut, natto. Making homemade fermented food is inexpensive but very effective as it contains large amounts of bacteria, including lactobacillus strains.
- Adding prebiotics (fibre) stimulate the growth of gut bacteria.
In addition, consuming less sugar and carbs and more healthy fats and fresh vegetables an cut the risk even more.
