On the guide page for the Temple Trekking / Burgh de Rott Ramble activities,

you have a list of "allowable" foods which you can give to the NPC followers

before starting a trek. While I cannot give anything not on this list to an NPC

before the trek, I have found that I can give anything I have tried so far to

the NPC during the trek itself and it will be accepted.

 

Things I have been able to give include sharks, karambwan, cod and mackeral.

 

I have been able to do this by right clicking on a food item and "using" it on the

NPC. If the NPC is below full health, it will eat the food immediately while saying

"Thanks, I'll get this down my throat right away" or something like that. I should

have written it down. If the NPC is at full health, it will say something along the

lines of "Thanks, I'll keep this to use later." The same 15 food item quantity

limit applies, I cannot give the NPC more than 15 foods. I can only give the

foods 1 item at a time unlike the pre-trek transfer.

 

This would probably be a very helpful thing to add to your guide. I know it

would have saved me a lot of time trying to pull together "approved" foods

to give to the NPCs.

 

It might also be noted that the NPC appears to be restored to full health at

the beginning of each event. Say I just went through a combat event and

the NPC took some nasty damage. If I offer food before moving on, it will

be eaten first and then stored. But if I continue the trek and wait until the

next (hopefully noncombat) event starts, then any food I offer goes straight

to storage.

 

I hope this information is of help to you and your user base. I wish I was

more literate and could provide screen shots of what I'm doing.
