Perhaps obviously, I disagree. It's not that every paper has to mention everything that's obvious, but my point was that the choice of how to frame the problem can be a political decision. There was no attempt to explain why micronutrient per serving of rice was the right metric, and I think using it can be misleading if the amount of rice grown changes for the same reason that the nutrients are dropping. And while "everyone knows" that yields will increase, there is disagreement on whether the increase in yield is dependent or independent of the change in nutritional value. By the way, I liked your comment elsewhere in this thread about eating plain rice. But rather than lamenting that all the references are behind paywalls, I personally think it's better just to give the DOI's and a link to http://sci-hub.tw http://sci-hub.tw. Or even better yet, just link to the papers, profits of publishers be damned. The world is better off when more people read the actual science.
