If only you were not so blind to the obvious.

The natural cures have been with us from the beginning, and no study is needed. Just a proper diet will provide the natural protection, and there is no need to get sick.

Use unnatural substances, and inevitably you will become ill; some quicker than others, but all will get their chance.

The natural cures have been with us from the beginning, and no study is needed.

Really? How do you demonstrate that a "natural cure" is effective? Do we just take the village priest's word for it, or would it be a good idea to apply the scientific method to test whether something is an old wives tale, or actually effective?

Just a proper diet will provide the natural protection, and there is no need to get sick.

Could you please explain the proper diet that will provide the natural protection against the bubonic plague? How about smallpox? Or what about malaria?
