There is not enough fruit and vegetables in the world for everyone to have healthy diet, new study reveals

Scientists say switch to healthier crops and plant-based proteins required to provide humanity with balanced diets in future.

The world is not growing enough fruit and vegetables for everyone to eat healthily, according to a new study.

A global appetite for fat and sugar, alongside a surge in grain production to feed developing countries, has led to a system that cannot provide balanced diets for all.

 

In order to feed the world’s rapidly expanding population with healthy diets, the scientists said more fruit and vegetables must be produced alongside a shift to plant-based proteins.

 

They then worked out how much land is currently used for farming, as well as how it is currently divided, and how much would be needed if everyone stuck to the Harvard system.

 

The results revealed a rift between the ideal and the reality, with 12 servings of grain being produced per person, instead of eight, and just five servings of fruit and vegetables instead of the recommended 15.

 

Levels of fat and sugar production were also far higher than is necessary for a healthy population.

 

In order to achieve self-sufficiency, developing countries have pumped masses of investment into grain and corn production in recent decades, and the researchers said some of this capacity must be swapped for other crops.

 

There was also a smaller shortfall in the amount of protein being produced, with three servings per person instead of five.

 

To bring protein consumption up to the required amount, the scientists recommended that a greater emphasis must be placed on plant-based proteins instead of animals.

 

“Major players in the protein industry are investing in alternative protein options such as plant-based proteins, and consumers are taking advantage of the recent increase in alternative protein options hitting the market,” said Professor Fraser.

 

Meat production uses huge amounts of land and resources, and is a major contributor to greenhouse gas emissions.

 

Unless the appropriate changes are made, feeding the 9.8 billion people expected to make up the global population by 2050 will require 12 million more hectares of arable land and at least one billion more hectares of pasture land.

 

Shifting production to match the health needs of the population would conversely slash the required arable land area by 50 million hectares, as these crops need less space than grains.
