The Power of Probiotics and the Gut-Brain Axis
In part five of the gut and brain series, we’re giving you the low down on the role of probiotics in maintaining a healthy connection between the brain and the ‘second brain,’ as the gut is often known.
The connection
We know by now that the vast community of microorganisms that reside in the gut known as the microbiota have an enormous impact on the health of our brain, our cognitive function, and our mental health.
The bacterium within the gut is delicately balanced, and a dysbiosis of this equilibrium can negatively affect our digestion, stress levels, and brain health. That’s where probiotics come in.
What are probiotics?
Probiotics are live microorganisms derived from foods and supplementary sources that, consumed in adequate amounts, have been shown to offer significant benefits when it comes to maintaining a healthy gut, and thus, a healthy brain. Let’s look at what the science says:
Neurotransmitters and mood
Feel-good neurotransmitters including GABA, or gamma-aminobutyric acid, and serotonin play a key role in regulating our moods, helping us to control anxiety and stress. Researchers have found that certain strains of probiotics, in particular Bifidobacterium and Lactobacillus, can assist in modulating the production and release of these neurotransmitters.
Cognition
Probiotics may also provide a helpful approach to dealing with many of the issues faced by an aging population. Preserving cognitive health is of paramount importance as we age. Since probiotics are linked to improvements in the gut-brain axis, they have excellent potential to offer an extra layer of support in warding off a range of neurodegenerative diseases, including dementia and Alzheimer's.
In addition, probiotic bacteria also contribute to the production of SCFAs, or short-chain fatty acids, via the fermentation of dietary fibers. SCFA’s have been associated with better cognitive function, and, again, a reduced risk of neurogenerative disorders.
The gut barrier and inflammation
To prevent the infiltration of harmful substances into the bloodstream, the body must maintain a healthy gut barrier. Probiotics contribute to the maintenance of a strong gut barrier, thus decreasing the chances of systemic inflammation and potential neurological consequences.
Talking of inflammation, chronic inflammation is a fundamental component of many neurological issues. Studies have revealed that probiotics show anti-inflammatory properties, helping to promote improved mental well-being.
Probiotics will likely play a pivotal role in the prevention and treatment of a wide range of digestive health, mental health, and neurological conditions in the future. So why not get ahead now?
