Muhtasari	The Nutrition Environment Measures Survey (NEMS) is a family of structured observation instruments for assessing the consumer nutrition environment — the in-store and in-restaurant conditions that shape what people can actually buy and eat. Developed by Karen Glanz, James Sallis, Brian Saelens and Lawrence Frank and published in 2007, NEMS-S audits retail food stores and NEMS-R audits restaurants, each scoring the availability, price and quality of healthier options relative to standard ones. Trained raters apply a fixed protocol so that two independent observers reach the same verdict, and the resulting scores let researchers compare neighbourhoods, link environments to diet and obesity, and evaluate interventions. NEMS is widely regarded as a foundational, validated tool for measuring the food environment and has been adapted across diverse settings since its release.	Dietary pattern analysis is the nutritional-epidemiology application of multivariate statistics that identifies how foods are actually eaten together, summarizing the whole diet into a few empirical patterns rather than studying single nutrients in isolation. Introduced as a research direction by Frank Hu in his 2002 Current Opinion in Lipidology review and surveyed methodologically by Newby and Tucker in 2004, the approach takes a matrix of food-group intakes and applies factor (principal component) analysis, cluster analysis, or reduced-rank regression to extract a posteriori patterns such as a 'prudent' pattern rich in fruits, vegetables, and whole grains and a 'Western' pattern high in red meat and refined foods. While the underlying algebra is generic principal component or cluster analysis, what makes this a distinct method is its substantive construction: the input is the food-group intake matrix of the whole diet, and the output is interpretable eating patterns linked to disease.
