Each of the substances of a man’s diet acts upon his body and changes it in some way and upon these changes his whole life depends.
Other Hippocrates quotes:
A wise man ought to realize that health is his most valuable possession and learn how to treat his illnesses by his own judgement.
Make a habit of two things: to help; or at least to do no harm.
Illnesses do not come upon us out of the blue. They are developed from small daily sins against nature. When enough sins have accumulated, illnesses will suddenly appear.
If you are in a bad mood go for a walk. If you are still in a bad mood go for another walk.
All disease begins in the gut.
