Your data,
your health,
your way
70% of your diet comes from what’s in your trolley.
That’s why smarter health starts with what’s already there – your habits, your choices, the life you’re already living.
We turn supermarket data into actionable health insights. No jargon, no finger-wagging, and no need to reinvent your life.
Just simple, personal guidance – powered by your data, built for real lives, and designed to make healthy living simpler for every UK household.
There are hundreds of metrics for health and nutrition, and most I don’t understand (or care to). [Truth Trolley] removed that barrier to reassessing my habits, and made me more aware of what I’m buying, helping me to make healthier choices day to day.

What Is Your Truth Trolley Score?
Your Truth Trolley Score is a simple, powerful way to understand the nutritional quality of your grocery shopping—based on real data reclaimed from your supermarket loyalty cards. We score your habits on a 0–100 scale:
100 = Strong alignment with public guidelines on healthy eating
0 = No alignment with those guidelines.
How Is Nutritional Quality Measured?
At Truth Trolley, we celebrate the joy of food—while championing the importance of balance and moderation.
Our scoring system is grounded in trusted public health guidelines and built around two key pillars of nutritional balance and moderation.
Balanced Nutrition
Good nutrition starts with variety. We assess how well your trolley includes essential food groups—like fruits, vegetables, grains, protein, and dairy—to support long-term health.
Moderation
Some things are better in smaller amounts. We check how well you’re managing ingredients like fats, salt, and added sugar, which can affect health when consumed too often.

The Truth Trolley Chat
The Truth Trolley Chat is a powerful way to spark real change at home.
Talking about food as a household isn’t always easy—but your shopping data makes it simple, honest, and blame-free. The Truth Trolley Chat turns your trolley into a conversation starter, using real data to open up a shared understanding about what you’re eating and why.
When the conversation is grounded in data, it’s easier to move forward—without emotion, guilt, confusion, or pressure. Just real insights, real goals, and real progress.
Set Targets
Once you’ve had the chat, it’s time to agree on a few realistic, shared goals. Maybe it’s “more veg,” “less processed,” or “cutting back on added sugar.” Use your Truth Trolley Score to pinpoint what matters most for your household and choose a couple of small, achievable targets to start.
Make Changes to Your Weekly Grocery Shopping
Small changes at the supermarket can lead to big shifts over time. Swap white bread for a wholegrain option, try a new veg each week, or reduce the number of UPFs in your trolley.
