Healthy Food Is a Maths Problem: Why “Just Eat Better” Doesn’t Work in the UK

“Eat better” is advice that assumes spare money exists.

For millions of households, it doesn’t.

The UK has a simple issue hiding behind complex debates:

healthy diets are unaffordable for too many people.

The Food Foundation has repeatedly shown that low-income households would need to spend a very high share of disposable income to meet healthy eating guidance.

This isn’t ignorance. It’s arithmetic.

Healthy eating becomes a penalty under pressure

When money is tight, every purchase must do a job:

• feed everyone
• fill people up
• avoid waste
• survive the week

Fresh food often loses because it comes with risk:

• it spoils
• it requires cooking time
• it needs storage and appliances
• kids might reject it

Households don’t “choose badly.”

They choose safely.

The hidden costs nobody includes

Even when the food itself is possible, the surrounding costs kill it:

• gas/electricity for cooking
• transport to cheaper supermarkets
• storage and fridge space
• time to prep
• stress and fatigue

That’s why diet inequality isn’t just food access.

It’s life access.

What fixes actually look like

If you want healthier diets, the system must make them easier:

• stable school meals
• community pantries with choice
• cash-first support that prevents crisis
• appliance support (fridge, cooker, microwave)
• local projects that reduce transport barriers

Healthy eating advice without infrastructure is just public shaming with extra steps.

Feed & Flow exists to fund the real-world fixes.
