cleansing is good.. try fibrous foods such as papaya, fennel, cardamom, Wormwood , and aloe ferox... it'll help you normalize your digestive system so you can be sure that all of the 'healthy' food that you eat will be absorbed by the body.. if you are constantly traveling there are a lot of natural products that are revolutionized,encapsulated, and the like)just look for d product which has the contents that i've mention because these are powerful fibers and antioxidants.
