Observational study of population level disparities in food costs in 2021 in Canada: A digital national nutritious food basket (dNNFB)
The aim of this work was to assess the feasibility and effect of applying a nationally representative and highly disaggregated food costing measure across Canada, through the novel application of web-scraping technology to the methods of the National Nutritious Food Basket (NNFB). Further, this stud...

The aim of this work was to assess the feasibility and effect of applying a nationally representative and highly disaggregated food costing measure across Canada, through the novel application of web-scraping technology to the methods of the National Nutritious Food Basket (NNFB).

This was an observational cross-sectional study using web scraped food price data collected in November 2021.
