Dietary fiber acts as fuel for gut bacteria, promoting the production of short-chain fatty acids that have anti-inflammatory effects on the brain. High-fiber foods such as oats, beans, and vegetables like broccoli encourage diverse microbial communities, which are associated with better emotional regulation. Low fiber intake, on the other hand, can lead to dysbiosis, potentially exacerbating mood swings or fatigue.
Integrating more fiber into your diet not only aids digestion but also supports mental clarity and emotional balance, as evidenced by research linking high-fiber consumption to lower risks of psychiatric disorders.
