Have you ever noticed how you often feel grumpy or irritable when you have gut issues? Feeling bloated for example is not conducive to a happy outlook!
This is because our gut and our brain are directly connected via the hypothalamic-pituitary-adrenal (HPA) axis.
What does this mean?
Our gut is made of billions of bacteria but it also houses over 100 millions neurons. The nerves within our gastrointestinal tract (the enteric nervous system) connect the gut to the brain: this allows the brain to influence our gut functions and, in turn, our gut influences our mood, cognition, and mental health. Our gut and brain use the same neurotransmitters and thus affect each other in a bi-directional way.
So, does this mean that we should take care of our gut to improve our mood? The answer is: YES!
So what we eat does impact our mood!
