In the early 2000s, “healthy eating” was driven more by marketing than understanding. Supermarket shelves were full of products promoted as good-for-you — even when they were heavily processed or packed with sugar.
One of the biggest examples was low-fat yoghurt. Fat was removed, sugar was added, and the product was sold as a smart choice. Bright packaging and fruit imagery helped sell the idea.
Cereal bars were another staple. Marketed as wholesome snacks, many were little more than compressed syrup and refined grains. They appeared in lunchboxes daily, rarely questioned.
Breakfast cereals were similar. Chocolate-coated and honey-frosted options were advertised as part of a balanced breakfast, with cartoon characters and bold health claims doing most of the convincing.
Fruit juice also escaped scrutiny. Despite containing as much sugar as fizzy drinks, it was widely seen as nutritious. Squash and juice cartons were packed without hesitation.
Even spreads played a role. Margarine and “lighter” spreads replaced butter in many homes, promoted as the healthier option despite heavy processing.
What’s striking isn’t that people got it wrong — it’s how confidently these foods were sold as healthy. Nutrition advice has shifted dramatically since then.
Looking back, these products highlight how much our understanding of food has changed — and how powerful marketing can be in shaping what people believe is good for them.
