15. Whole Grains
Research on the human diet has taught us that the brain prefers to burn glucose for fuel. Glucose is the sugar naturally found in carbohydrates. That being said, not all carbohydrates are created equally. Low-quality carbohydrates digest quickly, resulting in blood sugar spikes. As energy levels go up and then bottom out, so does your mood.
The quick increase and sharp drop in energy results in brain fog and mood swings. When you eat sustainable foods like pasta, however, your body has the energy needed to regulate mood. Whole grains also nourish the good bacteria in your digestive tract. A healthy gut microbiome has been linked to better mood and lower occurrence of mental health problems.
