Seven servings of fruit and vegetables a day, go easy on the fat and don't overdo it with the sugar: everybody knows how to eat healthily. And most people do think they do so. This just makes it clear how difficult it is to properly assess your own eating habits.

In the last ten years, the number of overweight and obese (severely overweight) people has sharply increased worldwide. In the Netherlands, some 4 in 10 men and 3 to 4 in 10 women, or some 3.5 million adults, are overweight. This means they suffer from an increased risk to develop cardiovascular diseases, high blood pressure, diabetes and arthritis. But eating healthily is also important to people of normal weight.

But what exactly does constitute 'healthy eating'? Most people think of bland meals when considering healthy foods. A shame, because healthy foods can be very tasty and varied. Have a look at the voedingscentrum (Dutch only) website for tasty and healthy recipes, for instance. Eating healthily doesn't mean you can never gorge yourself on something delightfully unhealthy like a burger or a box of chocolates.

Wondering if you're eating healthily? You can test yourself by taking all sorts of food tests (Dutch only) (e.g. the fat test, the fruits & vegetables test, the snack test).
