The gut health is very important in our overall health and well-being. Recent studies have illustrated the importance of “gut health” in regard to brain health and the central nervous system. 

“ALL diseases BEGIN in the GUT”- Hippocrates.

The gut health defines brain health and the central nervous system.The term “Gut Health” has become very popular in relation to both wellness and as a cause of disease conditions such as obesity, Type 2 Diabetes, metabolic syndrome and even certain types of cancers. Naturopaths, healthcare practitioners, dietitians, nutritionists are now understanding the importance of healthy gut and why it is important in our overall health and well-being.

The “GUT “ defines health: 

The “GUT “is what defines HEALTH. It is ground zero of our immune system. Only if the gut works in an optimal manner i.e. the way the food is digested and absorbed can we claim “You Are What You EAT”. Gut is so pivotal to our overall health- both physical and mental. Recent studies in scientific journals have illustrated the importance of “gut health” in regard to brain health and the central nervous system.

The Bidirectional gut brain axis wield power on our brain through multiple signaling mechanisms and it plays an important role in human brain diseases such as anxiety, depression, the way we feel pain, emotions, disorders of mood and even as a cause for Autism, Parkinson’s and Alzheimer’s.

95% of serotonin which is a neurotransmitter is made and stored in our gut. The signaling that happens between the Little Brain- the GUT and the Big Brain –can determine our energy levels, brain fog, fatigue, alertness and our cognition. So the food we eat has an effect on our day to day brain function and also can have a causative effect on allergies, autoimmune diseases such as Rheumatoid arthritis, and inflammatory diseases such as Crohn’s , Ulcerative colitis etc. just to name a few.

Overuse of different medications such as antibiotics, long term use of medicines for chronic diseases such as diabetes, obesity alter the beneficial microbes in the gut and cause an imbalance which in scientific terms is called as “ dysbiosis”.

Important nutrients for brain health:

The gut health defines brain health and the central nervous system.1. Omega 3 fatty acids: Rich in Fish (salmon), flax seeds, chia seeds, kiwi fruit, and walnuts reduce inflammation and also play an important role in the brain development of children during early childhood.

2. Flavonoids: Cocoa, green tea, citrus fruits, dark chocolate, red wine, purple grapes, Jamun has found to improve cognition in the elderly and also improve learning and memory in ischemic stroke patients.

3. B Vitamins: Pyridoxine (B6), Folate (B12) has positive effects on memory and performance and is found in oats, wheat germ, brown rice, eggs, certain veggies , soya beans.

world-microbiomeday.jBrain continuously uses glucose as its energy to function as an organ. Brain health is vital for the quality of life( QOL) at any age– we need focus, clear thinking, comprehending what happens around us, memory, good emotions like happiness, contentment and the RIGHT attitude to be of service to society and also to have a good family life. All these important brain functions are vital – whether one is in childhood, adult or senior age as this determines the QOL.

Healthy gut regulates the brain functions and emotions and hence “MINDFUL” eating loaded with good nutrients and avoiding junk foods saturated with sugar, trans fats, and empty calories will have an impact on our daily life. So every single food we eat and drink has a good or bad effect on our overall health and also on our brain health. World Microbiome Day is celebrated on June 27th every year.
