Both are fillers. Most likely these are the leftovers too. Probably 85% of people open up the box lunch at that conference and they’re disappointed to see an oatmeal raisin cookie inside. Or what I like to call the Counterfeit Chocolate Chip. However, if you’re someone that enjoys one or both of these “fillers” then you’re extremely happy because what was intended to just fill in the gaps has now rewarded you in a feast of good things.
But if the audience, your audience, doesn’t like any of the “fillers” then leave them out. Better to have less and it be the stuff people care about than just more fluff that’s going to look just like every other thing.
