All Scientific and medical research has to be funded from somewhere. And to make my point, this would include research on subjects around low carb diets which is championed on this forum.
Research funding will inevitably come from areas where there is interest, as government funding is more or less nonexistent. It doesn’t mean to say the research is tainted, which seems to be something that is brought whenever it involves a subject that doesn’t suit one’s thinking. These research papers do have full disclosure. It’s down to the individual whether one wants to take on board the findings within these reports. The Lancet does have an excellent worldwide reputation and papers published within are peer reviewed.
