Food for thought: raising the world’s IQ
4Digest
The episode begins with a discussion about the long-term effects of malnutrition on brain development, particularly during the first thousand days after conception. The Economist's deputy editor, Robert Guest, highlights the significant impact of malnutrition on cognitive abilities and its contribution to global economic losses. He also discusses potential solutions, including cash transfer programs and educational initiatives for mothers. The second segment focuses on the critical role of undersea cables in global communication and their vulnerability to sabotage. The Economist's defense editor, Shashank Joshi, explains the history of cable cutting as a military tactic and the growing concern over potential sabotage by Russia and China. He emphasizes the importance of undersea domain awareness and the geopolitical contest for control over cable infrastructure. The episode concludes with a discussion about a new innovation in menstrual hygiene, a polymer powder that can transform menstrual blood into a firm gel, potentially reducing leaks and spills. Emily Steinmark, a science writer for The Economist, explains the science behind this innovation and its potential to revolutionize menstrual products.

Keywords
Malnutrition
Malnutrition refers to a state of inadequate nutrition, which can be caused by insufficient intake of essential nutrients, poor absorption of nutrients, or increased nutrient requirements due to illness or infection. It can lead to various health problems, including stunting, wasting, and micronutrient deficiencies. Malnutrition is a major public health concern, particularly in developing countries, and can have long-term consequences for physical and cognitive development.
Brain Development
Brain development refers to the complex process of growth and maturation of the brain, starting from conception and continuing throughout life. It involves the formation of new neurons, the establishment of connections between neurons (synapses), and the pruning of unnecessary connections. The first thousand days after conception are considered a critical period for brain development, as the brain is highly susceptible to environmental influences, including nutrition, stimulation, and stress. Adequate nutrition is essential for optimal brain development, as it provides the building blocks for brain cells and supports the formation of synapses.
Undersea Cables
Undersea cables are long, insulated cables that are laid on the seabed to transmit data, electricity, or other signals across oceans and seas. They are essential for global communication, internet connectivity, and energy transmission. These cables are typically made of fiber optic strands encased in protective layers, including steel wires, aluminum barriers, and polyethylene. They are vulnerable to damage from natural disasters, fishing activities, and intentional sabotage. The security of undersea cables is a growing concern, particularly in the context of geopolitical tensions and cyberwarfare.
Sabotage
Sabotage refers to the deliberate act of damaging or disrupting something, often with the intention of causing harm or disruption. It can be used in various contexts, including warfare, industrial espionage, and political activism. In the context of undersea cables, sabotage can involve cutting, tapping, or disrupting the cables to disrupt communication or data flow. The potential for sabotage of undersea cables is a significant concern, as it can have far-reaching consequences for global communication, economic activity, and national security.
Menstrual Hygiene
Menstrual hygiene refers to the practices and products used to manage menstruation safely, hygienically, and with dignity. It encompasses a range of aspects, including access to sanitary products, proper disposal of menstrual waste, and education about menstrual health. Menstrual hygiene is a critical aspect of women's health and well-being, and access to safe and effective menstrual products is essential for women's participation in society and their overall health.
Alginate
Alginate is a natural polysaccharide derived from seaweed. It is a biocompatible and biodegradable material that has various applications in food, pharmaceuticals, and textiles. In the context of menstrual hygiene, alginate is used as a absorbent material in pads and tampons. It has the ability to absorb and retain fluids, including menstrual blood, and can help to prevent leaks and spills.
Q&A
What is the impact of malnutrition on brain development?
Malnutrition, especially during the first thousand days after conception, can significantly hinder brain development, leading to reduced cognitive abilities and impacting a person's ability to cope with the modern world. This can have long-term consequences for their education, employment, and overall quality of life.
Why are undersea cables vulnerable to sabotage?
Undersea cables are crucial for global communication and internet connectivity, making them attractive targets for sabotage. They are physically vulnerable to damage from ships, fishing activities, and intentional acts of disruption. The potential for sabotage by nations like Russia and China raises concerns about the security of these vital communication links.
How does the new polymer powder work to improve menstrual hygiene?
The polymer powder, made of alginate, interacts with the calcium ions in menstrual blood, forming a firm gel. This gel prevents leaks and spills, making it easier to manage menstruation and potentially reducing the discomfort and anxiety associated with periods.
What are some potential solutions to address malnutrition?
Cash transfer programs and educational initiatives for mothers can be effective in addressing malnutrition. These programs provide financial support and knowledge about proper nutrition, empowering mothers to provide their children with a balanced diet and improve their overall health and development.
What are the geopolitical implications of undersea cable security?
The security of undersea cables has become a major geopolitical concern, with nations like the US and Australia investing in alternative cable infrastructure to reduce reliance on Chinese companies. This highlights the growing importance of critical infrastructure in international relations and the potential for conflict over control of these vital resources.
Show Notes
If you don’t have enough food in the first 1,000 days of your life, your brain may never reach its full potential. Our correspondent discusses what better nutrition would mean for the world. Undersea cables are the arteries of our telecommunications system, but that also makes them vulnerable (9:13 ). And a new powder may help make periods less of a bloody nuisance (17:42 ).
