Does anyone have information on the impact and credibility of the publication (BMJ)? I'm a complete layperson in nutritional science so even though this speaks to me as a genuinely important perspective when it comes the bias of nutritional science I'd like to know if this is going to have any influence in the future. Additionally, how does this affect common meal replacements like soylent, huel, etc? Can we trust the nutritional science behind them if we presume the bias to be true as stated here?
