Bananas

Bananas offer serious mood-lifting power, with their combination of vitamins B6, A, and C; fiber; tryptophan; potassium; phosphorous; iron; protein; and healthy carbohydrates. When you eat a banana, you’ll get a quick boost from the fructose as well as sustaining energy from the fiber, which helps prevent a blood sugar spike and ensuing drop in energy and mood. Carbohydrates aid in the absorption of tryptophan in the brain, and vitamin B6 helps convert the tryptophan into mood-lifting serotonin. Bananas are also a great source of potassium. While potassium isn’t directly related to mood, it’s needed to regulate fluid levels and keep muscles working properly, which is important for feeling energized, a key factor for a sunny outlook. And finally, bananas also offer iron, which is crucial to producing energy and fighting fatigue.
