Trending Now: Warning: Worldwide Uniform Diet Is Dangerous
As the diets of countries are growing more and more similar, the global menu is getting smaller.
Research published in the "Proceedings of the National Academy of Sciences" looked at fifty years of data from the UN's Food and Agriculture Organization.
They found that diets across the world grew about 36% more similar.
People in a growing number of countries are consuming wheat, corn, meat, dairy and soybeans. That means they're eating fewer unique, regional crops. the researchers call this dangerous.
They say it's not good for health to rely on such a short list of major food crops, because it makes the global food supply dependent on such a short list of major food crops - setting us up to be much more vulnerable to things like new diseases or climate change that could wipe out a big part of the global food supply.
The researchers say more people are also eating more calories and fat which puts much more emphasis on needing to balanced nutrition.
