The Gut-Brain Connection: Nurturing Your Microbiome for Brain Health and Disease Prevention

The gut microbiome consists of multiple microorganisms, like bacteria, viruses, and fungi, that live in the human gastrointestinal tract, mostly in your large intestine. They are important to us due to their role in digestion, metabolism, our immune systems, etc. The microbiome is responsible for breaking down complex carbohydrates, producing different kinds of vitamins that our body cannot synthesize, helping us absorb different nutrients and protecting us against harmful pathogens. Based on how well our body performs in these functions, we can be less likely to develop diseases like Alzheimer’s and Parkinson’s disease and prevent illnesses like depression and anxiety.

New emerging research in animals and humans shows there may be a ‘gut-brain axis’ in our body that functions like a bidirectional communication network between your brain and your intestinal microbiome. Simplified, it means that if you eat well, you’ll feel well and if you feel well, you’ll eat well.

The gut microbiome is a complex dynamic system, which results in multifaceted connections as to how it affects your brain health. An unhealthy gut can lead to inflammation, which affects the blood-brain barrier (resulting in toxic material entering your brain and contributing to neuroinflammation). It can also compromise your immune system, which has been known to contribute to neurological disorders like multiple sclerosis.

To protect your gut health, one should aim to follow three main steps:

1.      Eat more probiotics and prebiotics: Probiotics and prebiotics are beneficial bacteria and the food that these beneficial bacteria consume. Foods like yogurt, kefir, sauerkraut, kimchi and other fermented foods are good ways to get in your probiotics. Prebiotics to consume, include garlic, onions, leeks, chicory root and asparagus to feed the growth of these gut bacteria.

2.      Consume more fiber: Eating a high-fiber diet through whole grains, fruits, vegetables, legumes and seeds can reduce inflammation and promote gut health.

3.      Limit processed foods with high added sugars: Having high added sugar foods has shown imbalances in gut bacteria and can often lead to growth of pathogenic bacteria at fast rates in your intestines.

In conclusion, the gut microbiome is a deeply complex ecosystem of microorganisms that need to be nurtured through various dietary choices to ensure that we can prevent brain disease in a world where brain disease is becoming ever so common.
