I agree there is an enormous amount of shady nutritional nonsense. I disagree with characterizing this study in that way. This study appears credible for suggesting an association. The authors do not misrepresent this. They acknowledge it does not determine any causality or solutions. Determining causality is expensive and time consuming. There is not enough research funding available to do that for every plausible hypothesis. We need retrospective studies such as this to determine where further funding should be applied.
