We used to think that anxiety, depression, grief, etc. caused tummy trouble, but increasingly researchers are thinking that it actually works the other way – an unhappy belly can make an unhappy brain. The good news about this is that it doesn’t take too much effort to put it right, but eating well is super-important.
We know there are trillions of microbes that live in the intestinal tract. These send signals to the brain that can change mood and behaviour. If you eat too much processed food or too much sugar (or not enough good food) it can knock out the balance of good bacteria in your gut. This can upset the balance of everything and heavily influence your mood by sending funky messages back to your brain. Eating unprocessed, healthy food, and food that contains good bacteria (such as miso or yogurt) can help to balance things out inside your gut and put things back on track.
There’s absolutely nothing wrong with eating something unhealthily delicious now and then, but make sure that you’re not overdoing it. The healthier your gut, the healthier your mental health. Gut bacteria are the rock stars of the mental health world. It’s really important to keep yours happy, because, you know – cranky rock stars can be painful and annoying and cause more than a decent amount of trouble.
