Washington DC: Appears if everyone on the planet wanted to eat a healthy diet, there would not be enough fruit…
As part of a new study, researchers studied global agricultural production with nutritionists’ recommendations for consumption and found a drastic mismatch. The study is published in the journal PLOS ONE.
Evan Fraser, co-author of the study said, “We simply can not all adopt a healthy diet under the current global agricultural system. Results show that the global system is currently overproducing cereals, fats and sugar, while the production of fruit and vegetables and less protein is not enough to meet the nutritional needs of the current population. “
Researchers calculate how much soil is currently used for agriculture and how much would be needed if all the nutrition recommendations were followed. They then projected these numbers by 2050, when the global population is expected to reach 9.8 billion.
They found that we now produce 1
2 servings of grain per person instead of the recommended eight. That is, five portions of fruits and vegetables instead of 15, three servings of oil and fat instead of one, three servings of protein instead of five and four servings of sugar instead of none.
“What we produce at a global level is not what we are going to produce according to nutritionists,” says Fraser.
He said that developed countries have subsidized grain and corn production for decades to become self-sufficient and to create global leadership in their production. These countries have also spent a lot more money on research and innovation for these crops than for fruit and vegetables.
Krishna KC, co-author of the study said, “Fat, sugar and salt are tasty and what we crave people so we have a real hunger for these foods. All of these factors have combined resulted in a world-wide system that overproduces These types of foods. “
The study suggested adopting a nutritional diet is not only good for us but also good for the planet.
The researchers also found that changing production to match nutritional nutrition guidelines would require 50 million fewer hectares of farmland, as fruits and vegetables take less land to grow than grain, sugar and fat.
In order to achieve this reduction, however, consumers would need to eat less meat, and the food sector would produce more plant proteins.
Without any change, 9.8 billion people will need to get 12 million hectares of a rable land and at least one billion hectares of pastures, Fraser said.
“The next generation feed is one of the most pressing challenges facing the 21st century. For a growing population, our estimates suggest that the only way to eat a nutritionally balanced diet, save land and reduce greenhouse gas emissions is to consume and produce more fruit and vegetables as well as transition to diets higher in herbal protein. “
