That is an excellent guide, albeit written with information that may turn out to be incomplete or wrong in the fullness of time. Interesting that he recommends 500mg of Vitamin C TID and 5000IU of Vitamin D daily. Vitamins A, C and E, in particular, have an anti-oxidant effect. One of the notable changes with age in the lung is a decrease in anti-oxidants. Of course we have learned since Linus Pauling's time that taking supplements and certain foods for their anti-oxidant value is not much use, likely because intra-cellular anti-oxidants are not particularly derived or influenced by dietary intake of same. One small difference here, however, is that the active anti-oxidants in the surfactant layer of the surface of the alveoli are, unlike the intra-cellular situation, almost entirely diet-derived. FYI Vitamin A is horrendously toxic in overdose. All the fat-solubles require care in dosing and some vitamins, certainly C, can interfere with medications.
