Health reporter Kelly Grant and her family of five lived for seven days without consuming any ultraprocessed foods to test the diet's feasibility [1, 2].

The experiment highlights the difficulty average Canadians face when attempting to remove industrial food processing from their daily routines. As concerns over the health impacts of ultraprocessed foods grow, understanding the practical barriers to avoidance is essential for public health planning.

Grant conducted the trial in early 2024 within her home in Canada [1, 2]. The goal was to determine if a typical household could realistically avoid these foods for a period of seven days [1]. The process involved identifying ingredients that meet the criteria for ultraprocessing and finding whole-food alternatives.

The household consisted of five people [2]. By restricting their intake to minimally processed ingredients, the family aimed to assess the health and practical impacts of such a restrictive diet. This involved changes to grocery shopping habits, and an increase in home cooking to replace convenient, pre-packaged options.

Ultraprocessed foods are typically characterized by industrial ingredients that are not used in home kitchens. Avoiding them requires a significant shift in how a family sources and prepares meals, a challenge that Grant sought to document through her personal experience [1, 2].

A personal experiment to live for one week without consuming any ultraprocessed foods.

This experiment underscores the systemic reliance on ultraprocessed foods in the modern Canadian food supply. When a health professional struggles to implement a whole-food diet for a single week, it suggests that the barrier to healthier eating is not merely individual willpower, but a lack of accessible, affordable, and convenient minimally processed alternatives.
