I'm from the Netherlands myself. I don't like to dine out, because usually you get a too small amount of fresh produce.
It could be that Dutchies get more exercise on average, because we like to ride bikes to work, etc.
We all could do with the advise from dr. Fuhrman from the USA (www.drfuhrman.com): eat significantly more fruit, vegetables and beans and less processed foods. Increase the nutrient density of your diets: instant weight loss and health gain. People might eat a little healthier in The Netherlands than the USA, but honestly all Western countries could improve a lot on this.
This article makes the mistake that greater body length equals healthier lifespan. There is no positive correlation, maybe even a negative correlation, because longer people have more body cells. Longer people often develop back problems.
