For years, the Netherlands has held the world title for having the tallest people on the planet. But new data from the office for national statistics suggest that the height of the average Dutch person is shrinking. And scientists are puzzled as to why.

At just over 6 feet for men and about 5-foot-6 for women, the Dutch are still the world's tallest population. But the growth that has seen the country to the top of global height charts for decades appears to have ground to a halt.

Scientists have offered a number of explanations - including the possible economic ramifications of the 2007 financial crisis, the increased consumption of unhealthy food, or even a shift from meat to plant-based diets while noting that such theories are speculative at this stage.

Such height studies are important, scientists say because taller people generally live longer. They are less likely to have difficult pregnancies or to develop heart or respiratory diseases. Taller people may also earn more money and be more successful in school.

Some think the reason could be plant-based diets but that's not been proven....... Americans have also changed....we're heavier......surprised?
