IMO, the extent to which nutrition is important against diseases should not be overstated.
The extent to which this is true is obvious. Many diseases that are internal, such as internal bacterial infection, fungal infection are strongly related to nutrition and water chemical quality.
This is so obvious that perhaps most people need not be reminded.
One very important consideration in this hobby is the closed nature of the tank. That is the lack of the dilution effect of the ocean. This is a very important consideration that should not be overlooked. In fact, it is hard to overstate this consideration.
Just think, even the most healthy and young people can get sick. If one is exposed to new patheogens, nutrition does not always help. This is in realtion to many external bacterial infections.
In regard to ich, nutrition link with ich is fickle. May be that the first fish in a tank get ich infestation due to stress (may be, even this is questionable), but such a fish will harbor and breed ich to such a high level that immunity can no longer be the issue.
Nutrition and disease is a rather limited link.
