Nutritionist Trudy Scott recommends a boiled egg: "Boiled eggs are a great source of protein and good fats for growing brains. The choline in the yolk is so important for brain health and as a chemical messenger between nerve cells. Eggs also help to keep blood sugar levels stable for better energy and mood. Eggs are also a good source of tryptophan (the 'happy' amino acid) and the B vitamins (important for energy, stress, and the brain). I do recommend pastured or at least organic eggs, since quality food is a big part of eating well and staying healthy. The great thing is that eggs are a low-cost, high-quality protein source."
