Fava beans are a great source of both fiber and protein. A single cup of fava beans contains 33 grams of carbs, 9 grams of fiber and 13 grams of protein. Apart from this, fava beans also contain trace minerals such as potassium, phosphorous, calcium and manganese. As an additional, psychological bonus, fava beans contain L-dopa, an amino acid that aids in the synthesis of dopamine (the "feel good" hormone). Aside from the "feel good" boosting, dopamine has also been linked to increasing the human growth hormone (HGH).
