The EatWell guide We're told to "eat a balanced diet" all the time — but what does that actually mean ? If you've ever stared at your plate wondering if you've got it right, you're not alone. The UK's Eatwell Guide is designed to answer that question. It's a simple visual tool that shows how different types of food should fit together to make a healthy, sustainable diet. But like most things in nutrition, the reality is more interesting — and more personal than a pie chart.
