By: A new evidence review has found that dairy makes an important contribution to healthy diets and the United Kingdom’s environmental targets, according to the Agriculture and Horticulture Development Board (AHDB).
The report was written by independent nutritionists and AHDB specialists in human health and the environment. It follows a similar assessment of red meat published earlier this year.
Rachael Madeley-Davies, AHDB’s head of environment, said the environmental impact of dairy has often been discussed without a clear picture of the science.
“The role of dairy in the UK has received plenty of media attention and debate over the last few years, but the evidence around its impact on the environment is disjointed and often lacking,” she said.
“Our review brings together the evidence to show that UK dairy farming is not only efficient but actively working towards sustainability targets, highlighting that it is among the most efficient and sustainable globally, with emissions intensity down 22% since 1990.”
According to AHDB, the review’s key findings include the following:
Health
- Dairy is a building block of healthy and sustainable diets and is an affordable source of nutrients in the UK.
- Viewing dairy as whole foods, rather than focusing on individual nutrients, offers greater dietary benefit.
Environment
- Well-managed livestock systems not only produce food but can also support carbon storage, habitat management and improved soil health, contributing to the UK’s net-zero goals.
Kate Arthur, AHDB’s head of nutrition and health, said dairy remains a central part of UK diets.
“Dairy is a cornerstone of UK nutrition, supplying essential nutrients like calcium, iodine and high-quality protein through all stages of life,” she said. “By providing a science-led foundation for marketing and policy, we hope that this report will strengthen the sector’s position in debates on health and sustainability.”
