We are pleased to present our detailed discussion of the link between high-fiber eating habits, mood, and brain chemistry. Nutritionists are often asked to explain the impact of different dietary options. The article below will answer one of these questions: Does a diet high in fiber affect your mental health?

How a high-fiber diet affects brain chemistry and mood

It's not just for digestive health that fiber is important. Research shows it can also have a positive impact on mental well-being. Recent research indicates that eating a diet high in fiber can improve brain chemistry, and even mood. Gut-brain communication is key - it links your digestive system to your brain.

In a study that was published in "Cell", it was revealed mice who were fed high fiber diets had higher levels of short chain fatty acids in their gut. The SCFAs have been shown to influence brain function, and possibly mood. A second study published in the journal "Nutritional Neuroscience", also confirmed these results, suggesting that higher intakes of dietary fibre may help reduce depressive symptoms.

How to Start a Diet High in Fiber

It's essential to know what a diet high in fiber entails before you start. A high-fiber diet includes foods rich in both soluble and insoluble fibers. Insoluble fibers are added to the stool and help digestion.
