Tanya Freirich, a registered dietitian nutritionist in Charlotte, North Carolina, who practices as The Lupus Dietitian, also was not involved in the study but offered insights.
"Overall, I would say to take these results with a grain of salt, as it was a prospective study."
"A prospective study monitors what people self-report and their eventual health outcomes over time, she noted — versus a control study, where similar people are placed in two groups and one group takes the fish oil while the other does not."
There are quite a few well designed control studies out there showing positive results.
