Hidden hunger, or micronutrient deficiencies, affects two billion people worldwide. It occurs when a diet is low in essential vitamins and minerals, especially iron, iodine, zinc and vitamin A.

Nutrition interventions like fortification and biofortification can help to dark web onion address these deficiencies. However, the most effective approach is to increase dietary diversity.
What is hidden hunger?

Hidden hunger – sometimes called micronutrient deficiency or malnutrition — happens when people don't get enough of the vitamins and minerals they need to live healthy lives. It's different from hunger caused by a lack of calories, which is more easily recognised and addressed. Hidden hunger affects 2 billion people globally. It is most common in low- and middle-income countries where diets tend to be dominated by cheap, energy-dense foods and where people don't have the opportunity to diversify their food sources.

Unlike famine and starvation, which often have visible symptoms, hidden hunger is harder to spot. This makes it harder to garner attention, investment and action to solve the problem. Hidden hunger also can be misunderstood, with some assuming it is just an issue for people living in lower-income countries or that it is simply a health problem that stems from obesity. In fact, many of the same reasons that lead to obesity — such as poor quality food and lack of exercise — can contribute to hidden hunger as well.

The most common symptom of hidden hunger is anemia – which can be caused by eating too little iron-rich foods like spinach and fish or taking too much caffeine (which reduces the absorption of iron). Other signs and symptoms of hidden hunger include fatigue, poor immune function and low productivity. Children and pregnant women are particularly vulnerable to hidden hunger, which can stunt their growth and cause learning difficulties. In addition, it can lead to long-term chronic diseases.

A variety of strategies can help to tackle hidden hunger. These include ensuring that people have access to a diverse range of affordable, nutritious foods; improving the quality of existing food; and adding micronutrients to staple foods – such as flour and salt. This approach is sometimes known as "biofortification". Other ways to address hidden hunger include prioritising the production of a range of nutritious crops and livestock; developing new crops that are more nutritious or drought-resilient; reducing transport costs and facilitating trade; and promoting market-based solutions. In addition, nutrition interventions can be targeted at specific groups of people who have higher needs – such as pregnant women and children.
Why is hidden hunger a problem?

Hidden hunger affects more than 2 billion people globally, mainly in low- and middle-income countries. It is a combination of nutrient deficiency and food insecurity and is particularly acute among pregnant women and children under five. It causes a range of health problems including anaemia, stunted growth, weakened immune systems and limited mental development. It is a major cause of preventable blindness in children and maternal deaths during childbirth. Unlike hunger caused by energy deficits, it does not have obvious clinical symptoms and therefore can be harder to garner attention, investment and action.

The main cause of hidden hunger is poor diets that are high in calories but not necessarily healthy or diverse, leaving the body lacking in essential nutrients like iron, zinc and vitamin A. These deficiencies can be addressed through better nutrition education and by ensuring that dietary change is supported with adequate financing, policies, and programmes.

Another solution is through fortification, where vitamins and minerals are added to processed foods to improve their nutrient content. Currently, there are methods to enrich or fortify many common staples such as cereals and flours, milk, oil, salt and sugar. However, this is not a long-term solution and should be supplemented with broader improvements to diets that include more legumes, fruits, vegetables and nutrient-rich animal-source foods.

Lastly, there is also a need to address the root causes of hidden hunger such as prioritising productive and nutritious crops and livestock; developing crop varieties that are more nutritious and drought-resilient (biofortification); and reducing trade and transportation costs. This will require a broad, multi-sectoral approach that involves governments, donors and private sector actors at all levels of the value chain.

Ultimately, a world free of hidden hunger is possible. The first step is to ensure that everyone has access to nutritious, affordable and sustainable staple foods. We can do this by investing in a more varied diet, including legumes, nuts, seeds, grains and nutrient-rich animal-source products; and by enabling farmers to produce a wider variety of micronutrient-enriched foods using biofortification technologies. By doing so, we can reach those who need it most and help them live healthier lives.
What are the symptoms of hidden hunger?

In the past, a well-balanced diet meant that you got both macronutrients (carbohydrates, proteins and fats) and micronutrients (vitamins and minerals). However, with the shift toward more processed foods, many people are missing out on key nutrients. In order to stay healthy and strong, we need to consume a wide variety of foods that contain essential vitamins and minerals. Hidden hunger occurs when your daily diet does not supply you with enough essential micronutrients, which can lead to illness and disease. In addition, some micronutrients, such as iodine, vitamin A and iron, are particularly important for children and pregnant women and deficiencies in these nutrients can lead to anaemia and stunted growth.

While much of the focus on malnutrition has been on preventing and treating classic deficiency diseases like rickets and scurvy, hidden hunger – also known as micronutrient malnutrition – is just as dangerous. In fact, it is more common than calorie malnutrition and affects over two billion people, or one in three individuals worldwide.

Unlike hunger caused by a lack of energy, which is easy to see, hidden hunger can go unnoticed and under-reported as it does not cause obvious symptoms or signs. Nevertheless, the health problems associated with hidden hunger – such as poor growth and development, impaired cognitive function, low immunity and anaemia – can be just as severe and can even result in death.

The causes of hidden hunger are largely due to low quality diets and food insecurity. For example, many high-nutrient foods are not available or affordable in low income countries. Furthermore, many of these foods are not prepared and combined in a way that maximizes the benefits of the micronutrient. For instance, spinach is a great source of iron but if it is not cooked properly or consumed with other foods that are high in iron, such as fortified breakfast cereals or milk, the iron will not be absorbed by the body.

The impact of hidden hunger is particularly pronounced during the critical 1,000-day window - the period from conception to the age of two - when adequate intakes of micronutrients are crucial for child health, survival and growth. It is also exacerbated by poverty and lack of knowledge about the importance of a balanced diet.
What are the solutions to hidden hunger?

Affecting over 2 billion people worldwide, hidden hunger is an invisible and often underestimated form of hunger. It is caused by deficiencies in micronutrients, which are essential vitamins and minerals that our bodies need for normal function but only in tiny amounts. When a person is deficient in these nutrients, they may suffer from cognitive impairments, compromised immune systems or chronic fatigue. This can limit their ability to learn, earn a living and live a healthy life. It can also stunt the development of entire communities and curtail economic growth in countries.

To combat hidden hunger, the most effective solution is to increase the dietary diversity of food available. This can be done through encouraging families to grow their own crops and eat more vegetables, fruits, pulses and dairy products. It can also be achieved by fortifying centrally processed foods such as salt, sugar and oil with micronutrients like iron, folic acid and vitamin A. In addition, micronutrient supplementation via pills and capsules can be a useful tool for targeting specific groups of people who are particularly at risk (e.g. pregnant women and children).

Addressing hidden hunger requires a holistic approach that prioritizes nutrition across different sectors and across all levels of government. It is important to invest in increasing the productivity of high-nutrient crops, developing drought-resilient varieties, and prioritizing agricultural research and innovation in new technologies that will help improve nutrient availability. It is also important to invest in health programmes that target micronutrient deficiencies and work to provide sustainable solutions to people who face chronic hunger.

It is also important to invest in improving the access and affordability of nutritious foods for all. Currently, low income families are most at risk of hidden hunger. This is because they cannot afford to buy enough of the right foods and have little access to affordable supplementation tools.

This problem is exacerbated by climate change, wars and disasters that can disrupt the production of nutritious foods. To overcome it, we must invest in sustainable solutions that provide universal access to nutritious foods.
