If you take a reasonable amount of vitamin C regularly, the incidence of the common cold goes down. If you get a cold and start immediately, as soon as you start sneezing and sniffling, the cold just doesn't get going.

...It would be possible to make much more progress than has been made if the NCI knew its job better, knew how to make discoveries...The NCI really does not know how to make discoveries....So long as the NCI is not willing to follow up ideas that seem good to people who have had experience making discoveries, the work of the NCI is going to be pedestrian.

We may say that life has borrowed from inanimate processes the same basic mechanism used in producing those striking structures that are crystals, with their beautiful plane faces.

Men will gather knowledge no matter what the consequences. Science will go on whether we are pessimistic or optimistic, as I am. More interesting discoveries than we can imagine will be made, and I am awaiting them, full of curiosity and enthusiasm.

Optimum nutrition is the medicine of tomorrow.

Science is the search for truth.

Science is the search for truth, that is the effort to understand the world: it involves the rejection of bias, of dogma, of revelation, but not the rejection of morality.
