In a state of nature there is no better doctor than a man's own appetite, and no doubt in a state of nature man could find the most palateable food the most wholesome.

Context

“If we had to wait till experience taught us to know and choose fit food for ourselves, we should die of hunger or poison; but a kindly providence which has made pleasure the means of self-preservation to sentient beings teaches us through our palate what is suitable for our stomach. In a state of nature there is no better doctor than a man's own appetite, and no doubt in a state of nature man could find the most palateable food the most wholesome. Nor is this all. Our Maker provides, not only for those needs he has created, but for those we create for ourselves; and it is to keep the balance between our wants and our needs that he has caused our tastes to change and vary with our way of living.” source
