I am a huge proponent of wheatgrass juice and usually have at least 2 shots a day, morning & evening, of my own home-grown (and using my own enriched compost). There is so much information on this magnificent superfood that I need not go into it here, suffice it to say that if wheatgrass juice is not in your daily routine, research it with a view to including it. Amongst other benefits, it is hugely detoxing and gives of its energy freely & is unlike any other food that I am aware of.
I can second the benefits of Himalayan rock salt, truely amazing stuff, I feel that it literally revives with the energy stored in its crystals. If you are not near an ocean where you can walk at the tide line this is second best IMHO.

Warm regards
