When humans first cooked food with fire, they not only made it taste better, but also made it easier and healthier to eat. Drying food allowed humans to store it for later. Ancient experiments with food chemistry gave us bread, yogurt, injera, and cheese, all of which are long-lasting and very tasty. This use of technology to enhance food made humans one of the most powerful animals on the planet, expanding our diet and helping us survive in tough environments. In this episode of N*gen, we explore the science behind traditional food processing methods and the new technologies used in modern factories to put food on supermarket shelves. However, many modern processed foods contain artificial ingredients that may be addictive and even harmful. Food technology has greatly increased our chances of survival, but has it gone too far?
