The role of nutritionists for better understanding of the nutritional waste of foods by consumers should be highlighted. It would be impossible to measure the waste of calories and other nutritional aspects of food being purchased and actually consumed by households without a clear measurement based on different food categories. In fact, representative/valid direct observation research methods are lacking from the international literature on food and nutritional waste. This would be the first step to assess the current levels of waste among households and opportunities for intervention. The research initiative being proposed by FAO and SESI to assess food and nutritional waste among households in Brazil may provide an important contribution for reliable domestic and international comparisons. Most of the studies found in the literature are estimates of waste, focus on specific geographical areas, and very few are current. The document should stress opportunities for direct observation research methods or what methods are considered the most relevant by the committee.
