 Welcome to Spotlight. I'm Colin Louther. And I'm Liz Wade. Spotlight uses a special English method of broadcasting. It is easier for people to understand no matter where in the world they live. In a village in Cambodia, a mother prepares food for her family. She boils some water in a big round cooking pot. She washes a small fish. Then she puts it in the boiling water. After 10 minutes, she removes the fish from the pot. Her family will not eat this fish. She puts other food into the pot to cook for her family. But what about the fish the mother took out of the pot? The family will not eat it. This fish is not food. It is made from iron metal. It is about 7.5 cm long and weighs 200 grams. The fish is smiling. The mother and her family like the fish. They call it their lucky iron fish. Thousands of families in Cambodia have a lucky iron fish. And like this mother, they all put their fish into their cooking water. Today's Spotlight is on the lucky iron fish. Christopher Charles studied health science at a university in Canada. When he finished his degree, he went to Cambodia. Charles lived in a small village in the country. His job was to treat particular infections. He also studied the health condition anemia. Anemia is a serious condition. People with anemia do not have enough iron in their bodies. They are iron deficient. People who have anemia are often very tired and lack energy. Anemia makes people more likely to be sick or get an infection. Anemia can damage the physical and mental development of children. If pregnant women are not treated, their babies can be born too early and die. If a new mother has anemia, she has an increased risk of dying when her baby is born. Charles did not know how common anemia was in Cambodia. But every place he went, he saw evidence of it. In a TED talk, he said, Everywhere I went, people were lying down. They were lying out of the heat of the sun. No one had any energy. No energy to work. No energy to play. No energy to learn. As part of his study, Charles did blood tests on many people. He discovered something shocking. About 90% of women and children had anemia. Charles had discovered a very big problem. He knew he could not leave Cambodia. He decided to stay and find a solution. Charles knew that iron medicine is the usual treatment for anemia. But iron medicine costs too much money. Charles wanted a solution that cost less money. It also had to be easy for people to use. Research shows that cooking with iron pots could help. The iron pot would release iron into every meal. But Charles knew this idea would not work in Cambodia. Iron pots are heavy and cost too much money. Also, in Cambodia, people often leave food in their cooking pots at night. Food goes bad if it is left in an iron pot. So Charles decided to try something different. He added a metal bar made of iron to a cooking pot. The iron bar worked but people did not cook with it. It did not cost much. It did release lots of iron. But there were huge problems with it. Everywhere I went, different families had found some use for it. Just not in the cooking pots. People were using it as a doorstop. People used it to hold down papers. Someone even used it to support a table with a broken leg. Finally, Charles created the iron fish. Fish are part of the culture of Cambodia. People in Cambodia eat fish every day. And they believe that fish are lucky. So people are happy to put the iron fish in their cooking pots. Sanshun is a village chief in Cambodia. She told the BBC how her family reacted to the iron fish. At first, my family thought it was very funny and very strange that I was putting the iron fish in the boiling water or soup. So I explained to them that it can improve our health and make us stronger. Charles had to be sure that the iron fish solved the problem of anemia. So he carried out lots of tests. And he found that the iron fish worked well. Charles tested people's iron levels. Then they used the iron fish for cooking every day. After nine months, Charles tested their iron levels again. He found that half the people had no anemia. People told Charles that they felt different too. They told him that they had more energy. Many people were pleased to take part in the tests. One mother told the BBC, I am happy. The blood tests show that I have the iron deficiency problem. So I hope I will be cured and will be healthy soon. I think all the people in our village will like the fish because fish is our everyday food. The iron fish has helped thousands of people in Cambodia. It has improved their health, but it has also helped the local economy. People who use the fish in their food miss less days at work. The iron fish has another economic benefit. Nearly 50 people have jobs from the iron fish. They make and supply the fish. The iron fish is good for the environment too. It is made from recycled iron, iron that was once used for another purpose. More and more people are using the lucky iron fish. In the next five years, Charles hopes that one million people in Cambodia will use the iron fish. But anemia is not just a problem in Cambodia. Anemia is a worldwide problem. It affects one in three people in the world. The World Health Organization says that iron deficiency affects more people than any other health condition. But in some places people do not eat fish. Charles says this is not a problem. The iron could be in a different form. What is important is that it is right for each culture. Then people will use it and it will improve their lives.
