text: what can a person drink or eat to act as natural mucolytic to help alleviate sinusitis?   i assume we're talking about chronic stuffiness, right?  if so, i find that, in my personal experience, it's not so much what i eat as it is what i avoid.  if you were my client, i'd suggest that you keep a food diary for a couple of weeks and see if you spot any patterns.  common foods that cause stuffiness include refined starches, rice and dairy.  (a plate of spaghetti will do it to me every time!)  best wishes.
