When people hear the word hunger, they usually imagine someone who does not have enough food to eat. But hunger is not always that obvious. Someone can have enough calories every day and still not get the vitamins and minerals their body needs.
This is known as hidden hunger, and it affects more than 2 billion people around the world. People may not realize they are missing important nutrients until the effects become serious. Micronutrient deficiencies can contribute to anemia, stunted growth and problems with physical and cognitive development. For children especially, what is missing from a meal can matter just as much as what is on the plate.
That is why food fortification deserves more attention.
Food fortification means adding essential vitamins and minerals to foods people already eat. Instead of expecting every person to completely change their diet or have access to expensive supplements, fortification can build nutrients into everyday foods such as rice, flour, milk and sugar.
Costa Rica is an example of why this approach can work.
The country has developed mandatory fortification programs for several staple foods, helping address deficiencies in nutrients including iron, iodine, vitamin A and folate. According to research from the National Library of Medicine, anemia among children in Costa Rica dropped from 19 percent to 4 percent after these programs were implemented. Among women, anemia decreased from 18 percent to 10 percent.
Those numbers matter because they show that fortification is not just an idea that sounds good on paper. When implemented properly, it can make a measurable difference.
But food fortification is not a solution to hunger by itself.
Around 2.3 billion people experience moderate or severe food insecurity worldwide. Someone who does not have reliable access to food cannot benefit much from nutrients added to food that never reaches them in the first place. This is especially important in low-income and rural communities where transportation, healthcare and clean water can already be difficult to access.
Nutrition is also connected to problems that do not initially seem related to food. Unsafe drinking water, for example, can contribute to disease and make it harder for people to absorb the nutrients they consume. Poor sanitation and limited healthcare can make existing nutritional deficiencies even worse.
That means the world needs to stop treating nutrition as an isolated problem.
International organizations such as the United Nations and UNICEF have already made reducing malnutrition a priority. But global efforts should focus not only on providing emergency food, but also on making the food people regularly eat more nutritious and making sure communities have the infrastructure needed to stay healthy.
This does not mean every country should simply copy Costa Rica. Different countries have different diets, economies and healthcare systems. A fortification program that works for rice in one country may need to look completely different somewhere else.
Fortification is not as visible as distributing thousands of meals or building a new hospital. That may be part of why it receives less attention. But sometimes the most effective public health solutions are the ones people barely notice.
Adding iron to flour or iodine to salt does not look like solving world hunger. But if it can prevent anemia, support childhood development and improve health on a large scale, it is worth taking seriously.
The world’s hunger problem is bigger than empty plates. If we want to actually improve global nutrition, we have to start paying attention to what is missing from the food people are already eating.
