Researched a little more today on unsaturated fat

it seems like soy and unsaturated fat are very similar in their immune suppression and thyroid suppression. I wonder if soy is just much more unsaturated fat than other unsaturated fats so the statistical people found that correlation easier.
there was also a research on cholesterol on that site that i found rather interesting and confusing. Apparently they think good cholesterol (HDL) and bad cholesterol (LDL) dont actually matter much - its the total cholesterol that had any statistical predictiveness, and only slight at that.
