المنتدى العالمي المعني بالأمن الغذائي والتغذية

The issues paper is broad and concise. As others have pointed out, it is an enormous task to review all the evidence (there is no suggestion of collecting new evidence). The issues paper rightly emphasizes the need to identify the drivers of change in food systems and consumer behaviours. I agree with this approach and although the issues paper does not name drivers i believe urbanization to be one driver that needs to be looked at. Food policy (or the absence of) is another.

The issues paper does not take a normative position with respect to types and characteristics of food systems. Many comments so far take strong normative positions, and there is no doubt that the HLPE Report on Nutrition and Food Systems will be normative, because it must determine actions to be taken to produce better nutritional outcomes.

It is likely that a typology of food systems might be needed, using a broad range of evidence sources, and an assessment of their effectiveness in terms of nutritional outcomes, again evidence-based.

My own view is that dietary diversity is a key factor in good nutritional outcomes and I believe this is supported by evidence. As noted in a previous comment, i am not comfortable with the term "over-nutrition", as it does not accurately describe some conditions which are really forms of malnutrition.
