How accurate is this?
Most of a stew's calories are oil, so a stew cooked with more or less oil than usual will be well off these figures.
Figures come from a study that weighed real portions on Nigerian adults' plates in Ibadan (Sanusi and Olurin, 2012), USDA FoodData Central and the FAO/INFOODS West African food composition table, combined at standard recipe ratios where a dish needed it. They are estimates for a typical home-cooked portion, not lab results for your plate.
