As a former healthcare professional I share your concerns about health matters here in Malaysia. Regarding the haze, it is definitely unhealthy, especially for those suffering from asthma, allergies and COPD. Even if you don't suffer from these ailments, you will in time suffer from respiratory problems. Here is a site you might find interesting:

Fluoride is toxic, but at a level that no human would ingest it ie. eating tablespoons of pure fluoride. Here is another site that deals with fluoride:

Tom's All Natural. My dentist friends back home say that brushing your teeth in baking soda is just as good or better than commercially toothpastes. It's cheaper too.
One concern you did not mention was medication given by the doctors here. When you visit a clinic or doctor they give you medication, many times with no name on the packet. They also do not tell you the side effects or ask what other medications you are taking that might be dangerous in combination. There is also no record of the meds they gave you. You have to be proactive and question the doctor about your medications. If interested I can give you a site that will keep a record of the drugs you are taking and tell you of the sides effects as well as what drugs are dangerous in combination.
