Most forms of cooking produce really alarming levels of particulate polution, regardless of the energy source.
If you have adequate ventilation to address the pollution from the cooking itself, then that is more than enough to address the combustion products.
From a policy perspective, cooking is a major energy sink that significantly occurs during peak hours (and outside of solar production)-- moving 100% of that load to the electrical grid seems far from desirable.
Particularly when the issue could (and should) be addressed with improved ventilation requirements for cooking areas, esp in California where the outside weather is usually mild enough that better ventilation isn't a big deal.
