Garbage disposal shoots water out the other sink drain.

When I turn my garbage disposal on, it shoots water and debris out the other drain first for about 1 second before it drains. I had 2 plumbers look at it, and one replaced the disposal saying it was too old. That fixed the problem for a few days, but it came back. The other one told me that there is no vent going to it, because it's in the island, and for whatever reason, they can't vent it up, so there is no vent, therefore the vacuum shoots the water up. Both checked the draining, and there are no obstructions in the water flow. Does this sound reasonable?
