Alcohol is metabolized to acetylaldehyde, which is also produced by candida. That is why some people with candida overgrowth feel like they have a hangover even if they don't drink. Molybdenum supplements will help break down acetylaldehyde. Aldehydes are also present in many perfumes, diesel exhaust, cigarette smoke, etc.
