A new study has reportedly found that out of 186 countries, only Guyana produces enough food to self-sufficiently feed all its citizens without foreign imports.

Published in Nature Food, the study investigated how well each country could feed their populations in seven food groups: fruits, vegetables, dairy, fish, meat, plant-based protein and starchy staples.

According to BBC Science Focus, it found that Guyana was the only country that could boast total self-sufficiency, while China and Vietnam were close behind, being able to produce enough food in six out of the seven food groups.

Worldwide, 65% of countries were overproducing meat and dairy, compared to their own populations’ dietary needs.

Just one in seven of the tested countries was judged self-sufficient in five or more categories, while six countries – Afghanistan, United Arab Emirates, Iraq, Macao, Qatar and Yemen – did not produce enough of any food group to be considered self-sufficient in even that category.
