概要	The Modified Retail Food Environment Index (mRFEI) is a spatial measure, developed by the U.S. Centers for Disease Control and Prevention, that summarises the retail food environment of a small area as the percentage of healthy food retailers among all food retailers in that area. For each census tract, the CDC counted healthy retailers (supermarkets, larger grocery stores, supercenters and produce stores) and less-healthy retailers (fast-food restaurants, convenience and small grocery stores) from national business databases, then expressed the index as healthy divided by all, times 100. Released in the 2011 Children's Food Environment State Indicator Report with census-tract maps for every U.S. state, the mRFEI offers a scalable, secondary-data way to flag food deserts (no retailers) and food swamps (dominated by less-healthy outlets) and to study how the food landscape relates to diet and obesity.	Nutrient profiling is the science of categorising foods according to their nutritional composition for reasons related to preventing disease and promoting health. A nutrient profiling model operationalises this idea as a transparent scoring algorithm: each food is awarded points for components considered detrimental in excess (energy, saturated fat, sugars, sodium) and points for beneficial components (fruit, vegetable and nut content, fibre, protein), and the net score is thresholded to classify the food as 'healthier' or 'less healthy'. The best-known example is the UK Food Standards Agency / Ofcom model (the WXYfm model developed by Rayner, Scarborough and colleagues), adopted in 2007 to restrict television advertising of less-healthy foods to children and later adapted by the WHO and as the underlying engine of front-of-pack schemes. Scarborough, Rayner and Stockley set out the systematic, transparent development process that distinguishes a defensible model from an ad hoc one.
