My naturopath does meridian test assessement which is the same as you describe; He initially tests several meridians in order to find the one thats most out of balance and then he goes through catalog in the software to find the best match for me as in supplements, foods etc.

well all the things you listed are pretty much the common food allergies .
and your body (the best tester of all ♥) agrees with what the test said.
be glad you found out those things. i did my findings by elimination dieting. (skipped out of common allergies to see if it affected me)
it took a lot longer and i wish i was able to test like you did.

more info on that testing system:

One system, which is beginning to grow in popularity among doctors and dentists, is a device known as the VEGA machine. The prototype of this system was developed by Dr. Reinhard Voll, a German physician. The VEGA comes with a hand-held electrical probe which the physician presses against the individual acupoint of interest. The patient holds a brass tube in one hand, which is connected by a wire to the VEGA Machine. By holding this tube, the patient permits a completed electrical circuit to occur when the metal-tipped probe touches the acupoint. The probe relays micro voltage electrical information from the acupoints to the VEGA Machine, where it is displayed on a type of voltmeter readout.
Certain levels of electrical norms for the acupoints have been established by Voll's previous research. The electrical voltage level for a particular acupoint reflects the energy level of its meridian associated organ(s). The direction of electrical deviation from the norm can have important implications about the nature of the underlying problem in a particular meridian. For instance, an acupoint voltage that is lower than normal may be caused by degenerative disease within an organ system or by conditions which produce a low general vitality. Conversely, higher than normal acupoint voltage readings can be indicative of an underlying inflammatory process.

The VEGA Machine allows one to carry out an energetic inventory of the functions of the different organs in a very detailed fashion. The energetic information may be in the form of too little or too much meridian electrical energy. This first step may give a clue as to the presence of degeneration or inflammation in the organ in question.
