Pumpkins Useless? Spoiler warning for food effects

So when I discovered the effect of pumpkins I was really hyped for the resistance effect, however the blaze powder thing that mobs drop replaces the pumpkin resistance with one that wears off almost immediately.

Is there a way to prevent this? It really sucks eating some preserved pumpkin before combat just to have your resistance immediately get cut short because the first mob dropped the blaze powder stuff
