Incidentally this is why there are limits on range hood CFM without makeup air (and there are broader recommendations on overall house design from groups like ASHRAE for air quality management). There are also whole-house leak tests in some regulations, e.g. Title 24 in California. Typically it's around 300CFM before you should consider a mechanical make-up air device (gravity activated or a makeup air fan tied to the hood activating).
