While they aren’t often the focus of news media, hunger and undernourishment are problems plaguing millions of people every day. It turns out a healthy diet is harder to achieve than you might think.
According to the UN Food and Agriculture Organization (FAO), more than 3 billion people could not afford a healthy diet in 2020. An additional 112 million more people than in 2019. The increase was partly because of rising food prices. With the average cost of a healthy diet rising by 3.3% from 2019 levels.
As of August 2022, the FAO food price index was up 40.6% from average 2020 levels. Unless income levels increased by a similar magnitude, the healthy diet crisis is likely to have worsened. Especially in low-income countries experiencing rampant food inflation.
Using data from the FAO, the above infographic maps the share of people unable to afford a healthy diet in 138 different countries as of 2020 (latest available data).
The Cost and Affordability of a Healthy Diet
According to the FAO, a healthy diet is one that meets daily energy needs as well as requirements within the food and dietary guidelines created by the country.
The (un)affordability is measured by comparing the cost of a healthy diet to income levels in the country. If the cost exceeds 52% of an average household’s income, the diet is deemed unaffordable.

In 52 countries, more than half of the population cannot afford a healthy diet. The majority of these are in Africa, with the rest located across Asia, Oceania, and the Americas.
By contrast, in four countries—Azerbaijan, Iceland, Switzerland, and the UAE—everyone is able to afford a healthy diet. The picture is similar for most European and developed high-income countries. There more than 95% of the population can afford a healthy diet.
When the percentages are translated into numbers, Asia contains the most number of people unable to afford a healthy diet at 1.89 billion. Of this number 973 million people are in India alone. Another 1 billion people are in Africa, with around 151 million people in the Americas and Oceania.
While hunger is a worldwide concern, it is particularly acute in African countries. This continent contains all of the top 20 spots in the above table.
Africa’s Deepening Food Crisis
In many countries across sub-Saharan Africa, more than 90% of the population cannot afford a healthy diet.
Sub-Saharan Africa is particularly susceptible to extreme climate events and the resulting volatility in food prices. Roughly one-third of the world’s droughts occur in the region. Some sub-Saharan countries are also heavily reliant on imports for food.
Russia’s invasion of Ukraine has deepened the crisis. With many African countries importing over 50% of their wheat from the two countries in conflict. The rising food prices from this supply chain disruption have resulted in double-digit food inflation in many African nations. This means that more people are likely to be unable to afford healthy diets.
The Horn of Africa region at the Eastern tip of Africa is particularly in turmoil. All the countries in the region are reliant on wheat from Russia and Ukraine, with Eritrea (100%) and Somalia (>90%) high up in the import dependency chart. Additionally, the region is facing its worst drought in 40 years alongside ongoing political conflicts. As a result, 22 million people are at risk of starvation.
Population Growth and Food Insecurity
In November of 2022, the global population is projected to surpass 8 billion people, and many of the fastest growing countries are also food-insecure.
By 2050, the global population is likely to increase by 35%, and to meet the growing demand for food, crop production will need to double. Given that agriculture is one of the biggest contributors to greenhouse gas emissions, this increase in crop production will also need to be environmentally sustainable.
As the impacts of climate change intensify and food demand increases, reducing food waste, building climate-resilient agricultural infrastructure, and improving agricultural productivity will all play a key role in reducing the levels of food insecurity sustainably.
