Da. I. N. KOG~MASS， distinguished physician， biochemist，<br >hematologist， and nutritionist， views us as two systems which<br >transform raw materials， supplied by the environment， in<br >"serviceable ways."<br > Physiologically， body chemistry elaborates Nature s ma-<br >terials into physiochemical compounds intended precisely to<br >meet the needs of the body machine， its bone， muscle， glands，<br >tissue， blood vessels， and cells. This is physiometabolism.<br > The other system is psychometabolism. Its basic material<br >is subjective experience; its product is， hopefully， psycho-<br >socially acceptable organization of feeling and thought.<br > "Psycho-nutrition" is a wedding of these concepts， for we<br >are and we think and we feel and function and are main-<br >rained with what we eat. If our nutrition--always a compro-<br >mise falling short of the optimal--in any way fails us， what<br >we are， think， and feel will change; and these changes will<br >feed back to and alter psychometabolism. Conversely， when<br >nutritional deficits are repaired--which may require heroic<br >amounts of nutrients usually needed in much smaller main-<br >tenance quantities--the responses in terms of more socially<br >acceptable feding and thought may (and o，ften do) make<br >the difference between being a dweller within the scene a.nd<br >being an outcast on its fringe or a cipher in its mental<br >institutions. So it is that psycho-nutrition is more than a new<br >approach to the problems of the neurotic， the schizophrenic，<br >the alcoholic， and the withdrawn， hyperactive， autistic， slow<br >leamer， or minimally brain-damaged， for--excitingly--it also<br >extends to normal children and adults a means， too long<br > neglected， of reaching potentials they never knew they had.<br > 9<br >
