The cost of a healthy diet has increased 25 percent in the past five years, putting it out of reach for one-third of the global population, according to figures released Wednesday by the United Nations.

The increased cost of food makes a healthy diet require an average of $4.28 purchase power parity dollars per person per day, per the UN Food and Agricultural Organization’s 2026 State of Food Security and Nutrition in the World report.

“As a result, 2.69 billion people -- almost one in every three people in the world -- still cannot afford a healthy diet,” Maximo Torero Cullen, the FAO’s chief economist, told a press conference.

The costs are not distributed equally -- staple foods such as beans, grains, for instance, account for 13 percent of the cost of a healthy diet, while animal products account for nearly 30 percent, and fruits and vegetables make up 16 percent.
