All people need good food. 

Food helps us stay strong. 
Sometimes, food is hard to find. 
Bad weather like floods can also cause problems. Wars and sickness can make it hard too.
In some places, it is harder for women to get food. It is also harder for people in the country.
Many groups work to make sure everyone can eat. They want to help end hunger for all. 
Food security means everyone has enough good food. 
Sometimes, food is hard to find. This is called food insecurity. Many things can cause this problem. High food prices make it hard to buy meals. Wars and sickness can stop food from moving. Bad weather like droughts or floods can also help cause it. 
Food insecurity affects many people. In 2024, about 2.3 billion people faced this problem. It is often harder for women than for men. It is also more common in rural areas.
Lack of food can cause serious health issues. For young children, it can stop them from growing well. This is called stunting. It can also affect how their brains grow. Many groups work hard to solve these problems. They want to reach a goal called Zero Hunger. 
Food security is a very important idea. It means everyone has reliable access to enough food. This food must be healthy and affordable. It also needs to be safe to eat. People must be able to meet their dietary needs. This helps them live active and healthy lives. Food security also means being ready for changes. People should not live in fear of starvation. This includes having enough food even during hard times. 
Experts use several pillars to understand food security. These include availability, access, utilization, and stability. There are two more important parts called agency and sustainability. Availability means the food is actually there to be used. Access means people have the money and ways to get it. Utilization means the body can use the nutrients well. Stability means the food supply stays steady over time.
Many things can cause food insecurity. This is the opposite of food security. It happens when food is limited or uncertain. High food prices are a major cause. Wars and conflicts can also stop food supplies. Climate change brings droughts and floods that hurt crops. Land degradation and water scarcity make farming much harder. Diseases in plants or pandemics can also cause problems. 
Food insecurity affects many people in different ways. In 2024, about 2.3 billion people were food insecure. This means they lacked regular access to adequate food. The global rate was about 28.0% in 2024. Food insecurity is rising in Africa right now. However, it is falling in Latin America and the Caribbean. It has also been decreasing in Asia for several years. In most regions, it is more common in rural areas. It also affects more women than men.
Not having enough food can cause serious health issues. For young children, it can lead to stunting. Stunting means a child does not grow as well as they should. This damage cannot be reversed after the age of two. Severe malnutrition can also affect how a brain develops. This is why many groups work toward "Zero Hunger." 
Food security describes a state where all people have reliable access to enough food. This food must be sufficient in quantity and high in quality. It must also be affordable, safe, and nutritious to meet dietary needs. 

To understand how food security works, experts look at several specific dimensions. The four main pillars are availability, access, utilization, and stability. Availability refers to the physical production and supply of food. Access involves the ability to acquire food through economic or physical means. Utilization, or nutritional adequacy, is how the body uses the nutrients provided. Stability ensures that food supplies remain steady over time.
Food insecurity is the opposite of food security. It is a state where the availability of suitable food is limited or uncertain. There are different types of food insecurity. Chronic food insecurity is a long-term, persistent lack of adequate food. In these cases, households are constantly at risk. Transitory food insecurity is more temporary but can lead to chronic issues. If food shortages happen repeatedly, households become more vulnerable to permanent hunger. 
Many complex factors can trigger food insecurity. High food prices are one of the most important causes. Disruptions in global food supplies, often due to war, also play a major role. Environmental issues like climate change, water scarcity, and land degradation make farming difficult. Agricultural diseases and pandemics can further damage food systems. 
In 2024, an estimated 2.3 billion people were moderately or severely food insecure. This means they lacked regular access to adequate food. The global prevalence of moderate or severe food insecurity was 28.0% in 2024. This rate has declined gradually since 2021, but regional differences remain large. Food insecurity is rising in Africa, where the 2023 prevalence was 58.0%. Conversely, insecurity is falling in Latin America, the Caribbean, and Asia. In most regions, food insecurity is more common in rural areas than in urban ones. It also affects women more frequently than men.
Food insecurity has serious consequences for human health and development. Severe malnutrition in early childhood can lead to defects in cognitive development. It can also cause stunting in children. Stunting is when a child's growth is slowed due to poor nutrition. Once a child passes the age of two, improved nutrition cannot reverse this damage. 
To track progress, many organizations use specific measurement tools. The Food and Agriculture Organization (FAO) uses the Food Insecurity Experience Scale (FIES). This scale helps researchers compare food insecurity levels across different countries. Other tools include the Household Dietary Diversity Scale and the Coping Strategies Index. The latter asks what people do when they lack food or money.
