Without taking into account the potential “inflammatory” effects of chitin from insects, a controversial experiment on undernourished African children aims to see if regular consumption of mopane worms and soldier termites can improve their nutrition.
Controversial Study on Insect Consumption in ZImbabwe to Improve Nutrition Sparks Concerns
A controversial experiment aiming to investigate the potential benefits of regular consumption of worms and termites on undernourished African children has raised eyebrows and sparked concerns. The study, funded by the UK government, is examining the impact of feeding underprivileged elementary school students in Zimbabwe with “insect-based porridge foods” promoted as a sustainable dietary option. As the project progresses, questions about potential health risks and the lack of informed consent have emerged, drawing attention to the ethical and scientific considerations surrounding this experiment.
The Experiment & Whats on the Menu: Mopane Worms and Soldier Termite Flour
The project, backed by the United Kingdom Research and Innovation (UKRI), involves providing mopane worm and soldier termite flour to undernourished elementary school students. The study seeks to assess how insect supplementation may affect children’s height, weight, micronutrient status, and cognitive function, as measured by academic achievement. Proponents argue that since rural communities in Zimbabwe have traditionally used these insect foods to prevent malnutrition during challenging periods like droughts and poor harvests, they are culturally acceptable in the region.

Missing Links and Health Concerns
While edible insects are touted as a valuable source of nutrients, the project description acknowledges the absence of a mechanistic link between insect consumption and health. Notably, it fails to mention any potential harmful health effects associated with frequent insect consumption.

Concerns have been raised regarding the presence of chitin, a compound found in insects, which studies have shown to be highly inflammatory and allergenic. Inhaling chitin has been found to trigger allergic inflammatory responses in the lungs of mice, leading researchers to explore its potential role in asthma development. It is crucial to consider the potential risks of chitin exposure before promoting widespread insect consumption.
Safety Concerns and Parasite Risk
Further safety concerns arise from a 2019 study that discovered parasites in 81% of inspected insect farms, with 30% of those potentially pathogenic to humans. The study highlighted the underestimation of insects as reservoirs for human and animal parasites. While the experiment aims to combat malnutrition, it is essential to carefully evaluate the potential risks and ensure appropriate safety measures are in place.
Broader Push for Insect Consumption
Efforts to normalize insect consumption as a sustainable dietary option have gained momentum globally. Insects, such as crickets, have been promoted as having more protein than beef without causing environmental damage. However, it is important to scrutinize the scientific basis and potential consequences of such claims.

Ethical Considerations and Historical Context
The experimental nature of the study and concerns surrounding informed consent cannot be ignored, especially considering Africa’s history of medical experimentation. Past incidents, like the unauthorized administration of an experimental drug to HIV-positive women in Zimbabwe and the Pfizer test in Nigeria, where children were given an experimental drug without proper consent, have left lasting scars. The absence of informed consent undermines the ethical foundation of any research involving vulnerable populations.
Scientists from the University of California, San Francisco, have discovered, for instance, that inhaling chitin “triggers an allergic inflammatory response in the lungs of mice,” and they are also investigating whether some people may be more susceptible to developing asthma as a result of their decreased ability to control their exposure to chitin.
What is Chitin
Its Role: Understanding Why Eating Insects Can Pose Risks for Humans
In recent years, there has been growing interest in promoting insects as a sustainable and nutritious food source. While edible insects are consumed by many cultures worldwide, it is essential to consider the potential risks associated with their consumption. One significant factor is the presence of a compound called chitin, which can pose dangers to human health. In this article, we explore what it is and why it is considered potentially hazardous for human consumption.
The Nature of Chitin
Chitin is a tough and fibrous substance found in the exoskeletons of insects and other arthropods, as well as the cell walls of certain fungi and algae. It provides these organisms with structural support and protection. Think of it as a strong armour or shield that helps insects and crustaceans stay safe and protected from their surroundings.
Digestive Challenges
Unlike other carbohydrates, such as sugars and starches, our bodies have difficulty breaking down and digesting chitin. This is primarily because humans lack the necessary enzymes to break it down completely. As a result, if we consume insects that contain chitin, our digestive system struggles to process it effectively.

Potential Health Risks
The resistance of chitin to digestion can lead to several health risks when consumed in significant amounts. The undigested chitin can cause discomfort, indigestion, and potentially blockages in the digestive tract. Imagine eating something that your body has difficulty breaking down and how it can cause tummy troubles.
Inflammatory and Allergic Reactions
One concerning aspect of chitin is its potential to trigger inflammatory and allergic responses in certain individuals. Research has shown that chitin can stimulate an immune response in the body, leading to inflammation. For those with existing allergies or sensitivities, consuming chitin-containing foods can worsen their symptoms and pose serious health risks.

Research and Safety Considerations
Scientists are actively studying the effects of chitin on human health and exploring its potential as a therapeutic agent for various medical conditions. However, the current understanding suggests that caution should be exercised when it comes to consuming chitin-rich foods, such as insects.
Promoting Informed Choices
While insects may be a common part of diets in some cultures and may offer nutritional benefits, it is crucial to consider the potential risks associated with its consumption. Individuals with existing digestive disorders or allergies should be particularly cautious. It is always recommended to consult with healthcare professionals or nutritionists before incorporating insects into your diet.
Chitin, a natural compound found in the exoskeletons of insects, can present challenges for human digestion and may trigger inflammatory and allergic responses. As we explore alternative food sources to address global challenges like sustainability, it is vital to consider the potential risks associated with consuming chitin-rich foods. More research is needed to fully understand the effects of of the compound on human health and to establish guidelines for safe consumption. In the meantime, individuals should make informed choices regarding insect consumption, keeping in mind their own health and any potential sensitivities they may have.
As the controversial study in Zimbabwe proceeds, it is crucial to address the concerns raised regarding the potential health risks and ethical considerations surrounding the experiment. While combating malnutrition is a noble goal, caution must be exercised to ensure the safety and well-being of the children involved. Further research and dialogue are needed to evaluate the potential benefits and risks associated with insect consumption, weighing both scientific evidence and ethical considerations. Only through a balanced approach can we safeguard the welfare of those involved and make informed decisions about nutrition interventions in undernourished communities.
