How much do you really know about dairy?
For generations, we’ve been told milk is one of the most natural, nutritious foods there is.
It gives us calcium. It builds strong bones. Children need it to grow. Cows simply produce milk.
These ideas are so familiar that most of us rarely stop to question them.
And that’s hardly surprising.
For decades, the dairy industry has had enormous resources behind it. Its messages have appeared everywhere – in advertising, schools, packaging and public campaigns – alongside those familiar images of cows grazing happily in idyllic green fields.
When we hear the same claims again and again, they become part of what simply feels normal.
But what happens when we look beyond the marketing?
What Do You Really Know About Dairy? investigates the science, the industry and the animals behind one of Britain’s most familiar foods.

The film
A 30-minute investigation into what we think we know about dairy.
In this powerful 30-minute documentary, Viva! founder and director Juliet Gellatley investigates what the public really knows about dairy; and where our beliefs about milk came from.
We hear from members of the public, explore some of the biggest health claims surrounding dairy and look at the reality of modern milk production.
Featuring expert insight from registered dietitian Rosie Martin, haematologist Dr Shireen Kassam and gastroenterologist Dr Alan Desmond, the film examines the health claims surrounding dairy and asks whether it really deserves the nutritional reputation it has enjoyed for generations.
And behind the familiar image of cows in green fields lies another story entirely.
One involving pregnancy, separation, intensive farming and an industry dependent on animals producing milk for human consumption.
Question the claims. Challenge the norm. Discover what you really know about dairy.

Why this film?
59 per cent believed cows produce milk simply because they eat grass.
Before making the documentary, Viva! asked the British public what they believed about dairy.
The answers revealed just how deeply some ideas have become embedded in our culture.
If we misunderstand something as fundamental as why a cow produces milk, what else don’t we know?

What you’ll discover
Six questions at the heart of the dairy story.
Calcium & strong bones
Where familiar health claims come from.
The marketing machine
How the dairy industry markets milk and dairy products.
Why cows produce milk
And what happens to their calves.
Dairy & health
What the scientific evidence actually tells us.
The reality of farming
How modern dairy differs from the idyllic image most of us recognise.
Life without dairy
Why plant-based diets can provide the nutrients we need without dairy.
Why have so many of us never been encouraged to ask these questions before?
“But I’ve always been told dairy is good for me…”
Exactly.
This film isn’t about blaming people for believing what we’ve been told.
Milk has been promoted as wholesome, natural and necessary for generations.
The dairy industry has enormous resources – and those messages have been repeated through advertising, education, packaging, government-backed campaigns and popular culture.
It is completely understandable that they became part of our everyday understanding of food.
The point isn’t to ask why we believed it.
It’s to ask what happens when we finally examine it.
