Summary
White and Broadley (2005) reviewed historical food composition data to evaluate whether the mineral content of edible horticultural products has changed over the twentieth century. The paper likely draws on UK food composition tables and comparable national datasets to identify temporal trends, considering agronomic, genetic, and methodological explanations for apparent declines. It contributes to the broader scientific debate on nutrient density change in food crops and the adequacy of modern diets in meeting mineral requirements.
UK applicability
This paper is directly applicable to UK conditions, drawing primarily on UK food composition data and published in a UK-based horticultural science journal. Its findings are relevant to UK policy discussions on dietary mineral sufficiency, crop breeding priorities, and sustainable horticultural practice.
Key measures
Mineral concentrations (mg per 100 g fresh weight) of key elements including calcium, magnesium, iron, copper, and zinc across historical food composition datasets
Outcomes reported
The study examined changes in the mineral concentrations of edible horticultural products — including vegetables and fruit — by comparing historical food composition data across decades. It assessed whether mineral content has declined over time and considered the potential causes of any observed variation.
