I will just start this off with mentioning a couple of them.
Green vegetables, green salads and in particular Wheat Grass Juice. The green is chlorophyll which is an oxygen producing agent that will increase the oxygen level of your blood giving you more strength and relieves tiredness.
Fish oil (Omega 3) enhances blood circulation. Eating fish will give you this oil plus the protein you need without the fat usually obtained from meat.
This is not a food but obtaining at least 30 minutes of sun light a day will produce vitamin D for your bones and it will enhance your mood. Sunlight is a mood booster. All musicians could use a booster for their moods.
