Washington DC: It turns out that if every human on Earth wants to eat healthily, there are not enough fruits and vegetables available to meet the demand.
As part of a recent study, researchers compared global agricultural production with nutritional recommendations and found a dramatic mismatch. The study appears in the journal PLOS ONE.
Evan Fraser, co-author of the study, said: "We can not feed all healthy under the current global farming system, and the results show that the global system is currently overproducing grains, fats, and sugars To a lesser extent, protein is not enough to meet the nutritional needs of today's population. "
Researchers calculated how much land is currently used for agriculture and how much would be needed if all were followed by dietary recommendations. Then they calculated these numbers for 2050, when the world's population is expected to reach 9.8 billion.
They found that we now produce 1
"What we produce at a global level is not what we should produce according to nutritionists," Fraser said.
He said that developed countries have been subsidizing grain and corn production for decades to become self-reliant and take global leadership in their production. These countries have also spent much more money on research and innovation for these crops than on fruits and vegetables.
Krishna KC, the co-author of the study, said: "Fat, sugar and salt are tasty and are what we humans long for, and that's why we have a real hunger for these foods." All these factors go together led to a world system that really overproduces this kind of food. "
The study suggests that a more nutritious diet is not only good for us, but also good for the planet.
The researchers also found that switching production to dietary guidelines would require 50 million hectares less farmland because fruits and vegetables need less land to grow than grains, sugar and fat.
But to achieve this decline, consumers would have to eat less meat, and the agri-food sector would have to produce more vegetable proteins.
Without change, the diet of 9.8 billion people will require 12 million more hectares "Fraser" (19659002) "Next-generation nutrition is one of the most pressing challenges of the 21st century. that the only way to eat a nutritionally balanced diet, to save land and reduce greenhouse gas emissions, is to consume and produce more fruits and vegetables, and move on to a diet with higher levels of vegetable protein.
