The Brain-Gut Connection for Mental Well-being

HomeLifeThe Brain-Gut Connection for Mental Well-being

Have you ever wondered the reason behind feeling butterflies in your stomach? Or that sinking premonition feeling around your stomach when something unexpected happens?

Several studies over the years have established the brain-gut connection and the condition of our gut influences one’s mental health. Human body consists of two brains. One is located in our head and the second one – in our guts, both these brains start forming at the time of fertilization.

They develop from the same cluster of tissue wherein one section evolves into a central nervous system (brain) and another one into enteric nervous system (gut). Vagus Nerve, longest of all the cranial nerves, connects both these nervous system.

Chemicals (hormones, neurotransmitters) that control the brain in the head are found in the gut brain as well. Due to this linkage between the brain and gut, researchers have concluded that a healthy gut helps in maintaining good mental and emotional health.

“Many of the gut signals reaching the brain will not only generate gut sensations, such as the fullness after a nice meal, nausea and discomfort, and feelings of well-being, but will also trigger responses of the brain that it sends back to the gut, generating distinct gut reactions. And the brain doesn’t forget about these feelings, either. Gut feelings are stored in vast databases in the brain, which can later be accessed when making decisions.” ~ Emeran Mayer, The Mind-Gut Connection: How the Hidden Conversation Within Our Bodies Impacts Our Mood, Our Choices, and Our Overall Health.

The impact of food on your brain

Human gut has a gut microbiota, which basically is clusters of several microorganisms living in our intestine. It contains tens of trillions of microorganisms, including at least 1000 different species of known bacteria with more than 3 million genes (150 times more than human genes).

According to studies, presence or absence of gut microbiota affects the development of behaviour that causes neurochemical changes in the brain.

Gut microbiota execute the communication-function with the brain. Their presence or absence influences the central nervous system and it’s behaviour. Hence, it is necessary that a healthy communication between gut and brain be ensured for avoiding psychiatric illness.

Research shows that eating food rich in omega-3 fatty acids will boost mental health, reduce irritability and reduce depressive symptoms. 

Additionally, about 70% of the cells that make up the body’s immune system is found in the gut. Therefore, it is highly advisable to keep your gut in check.

The positive effect of probiotics on mental health

Researchers at the University of California, Los Angeles (UCLA) assigned 45 women to receive either daily probiotic yogurt, non-probiotic yogurt or no yogurt at all. When the women were examined after 4 weeks, it was found that the women in the probiotic yogurt group had a more stable emotional response when exposed to a stressful situation.


Kirsten Tillisch who led the Californian researchers noted, “By changing the environment in the gut, we can actually change what happens in the brain”.

Steps to take to maintain a healthy brain-gut connection

Along with feeding your mind, feed your gut as well. There are innumerable ways to keep a healthy mind and gut simultaneously.

1) Include “prebiotics” in your diet each day. Prebiotics are hard to digest carbohydrates that increase the number of gut bacteria in your intestine. Like yoghurt, raw oats, garlic, onions, bananas, unrefined wheat and barley etc.

2) Don’t skip breakfast. When you wake up in the morning, your blood sugar level is low due to which you feel lethargic and lazy. To boost up your energy, have breakfast daily. Messing up with your sugar level is messing up with your body and mind energy.

3) Lack of variety in the diet means lack of variety in our gut bacteria. Work on having a wholesome nutritious meal.
4) Avoid acidic foods. Keep a check on your coffee and alcohol consumption.

5) Eat fruits. Fruits are the best source of enzymes and vitamins.

6) Several herbs like Cinnamon, cardamom, coriander etc come handy in feeding the good bacteria in the gut. They also eradicate the presence of unfriendly bacteria in your gut.

7) Decrease the level of stress hormones. Indulge in activities that you enjoy, sing, draw, dance.

8) Yoga and meditation are excellent ways to relax. Working out regularly boosts the presence of healthy hormones required for maintaining a healthy mind. It turns out they keep the gut happy too.

9) Keep your body and mind energy balanced by having several small meals throughout the day. A good metabolism is the key to excellent fitness of the being.

10) Keep a check on your digestion system. Have lots of water. Dehydration leads to several problems.

Unfortunately the author has little knowledge in nutrition and so please seek councel from a nutritionist rather than try and decipher the tips. It is easy to copy and paste someone else’s science but you should know your topic before adding your own advice.

If you have autoimmune issues like are advised to avoid grains and dairy which would make this plan in need of alteration…..

As someone who had c difficile/pseudomembranous colitis caused by an antibacterial wipe, the long term lack of biodiversity in my gut makes me wonder what sort of psychiatric illnesses I might be susceptible to in the future/what percent of my emotional responses to stress are currently affected by this

Bill Lee Emery

the enteric/gut brain is sometimes called the second brain but it is actually the first neural network/brain laid down in the womb. The cardiac network/brain is laid down next and finally the head or cephalic brain last. They all have their part of play in our lives and provide very different skill sets. We often get into trouble when we give a task or responsibility to a brain/intelligence that is not its best work!
