Synonyms diet, nutrition and usage of feeding [duplicate]

Question

We have several questions tagged diet or nutrition. I really don't see any difference between them.

feeding sound similarly close, too.

Answer 1

Both diet and nutrition are synonyms, I would prefer nutrition as the main tag as it sounds more professional and doesn't carry the connotation of weight-loss.

feeding should be perceived as the actual process of feeding (and methods used during the process). Which would have to be noted in the tags wiki excerpt.
