Brain function is controlled by messages sent via chemicals called neurotransmitters.
And many of our most common neurotransmitters such as GABA, norepinephrine, serotonin, dopamine, and acetylcholine are actually produced in the gut.
Serotonin is an important neurotransmitter which helps to regulate our sleep cycle and mood – it’s our de-stressing hormone. People who have low levels of serotonin experience anxiety, depression, aggression, irritability, and insomnia. 90% of our serotonin is produced in the gut by the billions of bacteria that make up our gut microbiome.
Several scientific studies have found that individuals with a healthy gut microbiome have decreased levels of stress, anxiety, and depression and have a generally more positive outlook compared to individuals with altered gut bacteria populations. More recent research is suggesting that our gut microbiome can also play a role in reducing chronic inflammation, regulating glucose and insulin balance, and might even improve cognitive scores in people with dementia.
The health of our gut microbiome is dependent on the foods we eat. The more whole, organic foods we eat, the healthier and more diverse our gut becomes.
