LOL, i just read this today about how researchers have compered the salivary bacteria in overweight people vs normal weight people in a clinical study and have discovered that certain types of bacterial associated with inflammation are highly elevated especially the species Selenomanas Noxia in people that are overweight. I wonder if cavities and gingivitis could be a factor somehow?
Anyway for those interested here's the article.
