Processed and Ultra-processed Food Products: Consumption Trends in Canada from 1938 to 2011
Abstract
Purpose: A classification of foods based on the nature, extent, and purpose of industrial food processing was used to assess changes in household food expenditures and dietary energy availability between 1938 and 2011 in Canada. Methods: Food acquisitions from six household food budget surveys (1938/1939 , 1953, 1969, 1984, 2001, and 2011) were classified into unprocessed or minimally processed foods, processed culinary ingredients, and ready-to-consume processed or ultra-processed products. Contributions of each group to household food expenditures, and to dietary energy availability (kcal per capita) were calculated. Results: During the period studied, household expenditures and dietary energy availability fell for both unprocessed or minimally processed foods and culinary ingredients, and rose for ready-to-consume products. The caloric share of foods fell from 34.3% to 25.6% and from 37% to 12.7% for culinary ingredients. The share of ready-to-consume products rose from 28.7% to 61.7%, and the increase was especially noteworthy for those that were ultra-processed. Conclusions: The most important factor that has driven changes in Canadian dietary patterns between 1938 and 2011 is the replacement of unprocessed or minimally processed foods and culinary ingredients used in the preparation of dishes and meals; these have been displaced by ready-to-consume ultra-processed products. Nutrition research and practice should incorporate information about food processing into dietary assessments.

The energy contribution of UPFs to total household food purchases increased in Spain, Canada, Mexico, Brazil, Argentina, China, South Korea, the USA, and the UK over recent decades.
“The energy contribution of UPFs to total household food purchases nearly tripled in Spain 39 over three decades (11•0% to 31•7%), more than doubled in Canada 40 over eight decades (24•4% to 54•9%), and increased from 10% to 23% in Mexico 41 and Brazil 42 over four decades (figure 1).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
