Summary

This study by Wang and colleagues, published in Public Health Nutrition (2010), analysed the macronutrient profiles of organic and conventional broiler chickens sold in the UK, finding that both product types derive a greater proportion of their energy from fat than from protein — a notable shift from the nutritional composition of chicken reported in earlier decades. The paper contributes to a body of evidence suggesting that selective breeding for rapid growth and changes in feeding practices have substantially altered the nutritional quality of poultry meat. The authors, known for their work on dietary fat and brain health, contextualise these findings within broader concerns about the balance of omega-6 to omega-3 fatty acids in the modern food supply.

UK applicability

The study was conducted using chicken samples purchased in the UK retail market, making its findings directly applicable to UK dietary assessment, food labelling policy, and public health nutrition guidance. The results are relevant to ongoing UK debates about the nutritional quality of intensively reared poultry and the value proposition of organic labelling.

Key measures

Energy from fat (kcal; % total energy); energy from protein (kcal; % total energy); fat content (g/100g); protein content (g/100g); fatty acid composition

Outcomes reported

The study compared the macronutrient composition — specifically fat and protein energy contributions — of modern organic and conventional broiler chickens available for retail purchase. It examined whether contemporary chicken products deliver more dietary energy from fat than from protein relative to historical benchmarks.
