The article talks about turning white, fat-filled blood red, so presumably it would have an effect on blood fat level. Is the issue that humans with this disease have no choice but to remain on extremely strict diets, which does a reasonable job of controlling their blood fat level. This treatment (cure, essentially) would alleviate that, but not necessarily change the levels much, since the patients were already (laboriously) controlling them?
