Teachers and parents! Our Teacher Edition on Survival of the Sickest makes teaching easy.
Malaria is a disease common to tropical climates which infects almost 500 million people and kills more than one million people every year. Malaria is caused by parasitic protozoa which infect mosquitoes, and the disease is then transmitted by mosquito bites through the blood of humans. Malaria causes joint pain, vomiting, and anemia. Ultimately, it can lead to coma and death, especially in children and pregnant women. Having anemia provides some resistance to malaria, because without healthy red blood cells, it is difficult for the protozoa to infect the cells. This is why favism, which leads to fewer healthy red blood cells, can provide some advantage against malaria.

Chapter 4 Quotes

By releasing free radicals and raising the level of oxidants, fava bean consumption makes the blood cells of non-G6PD deficient people a less hospitable place for malarial parasites. With all the free radicals, some red blood cells tend to break down. And when someone with a mild or partial deficiency in G6PD eats fava beans, the parasite is in deep trouble.
