Citron's Eating Habits

Throughout most of history, most people never got enough to eat, and many people starved to death. Food costed more than it is today, and governments helped people out less than they do now. Even farmers often went hungry when city people took all their food for themselves as taxes, or if the weather was bad and storms or diseases ruined the crop. Children went hungry more than their parents, because if the parents died. Than children are going to have a higher chance of dieing instead of the other way around.
When people could get food, the food people ate varied a good deal from time to time and from place to place. So you'll need to read about each time and place separately. There are some things all these times and places had in common,
As early as the Stone Age, people were eating citron fruits in China, too. Citron fruits may have reached China by floating in the ocean, or people on boats may have brought it. Citrons spread from the Pacific across Southeast Asia to India, too, and from China and India Citrons soon reached Central Asia, West Asia, and East Africa. Citron appears in an Egyptian tomb painting from1000 BC. These citrons were not juicy, and people mainly ate the rind rather than the fruit, or used citron rind to make perfumes.Indian doctors knew citrus could cure scurvy (Vitamin C deficiency), and so they tried it for a lot of other illnesses too. Citrons reached ancient Greece and Rome not much later; Theophrastus described the fruit in 310 BC. Those came from two other kinds of citrus fruit, cousins of the citron, called the pomelo and the mandarin. Either Chinese Or Indian food scientists bred the pomelo and the mandarin together sometime before 314 BC to get new fruits - the bitter orange and the sweet orange. Indian cooks used bitter orange to make pickled oranges. They called the trees naranga. That's where our word "orange" comes from. These oranges spread west along the Silk Road. The bitter orange (but not the sweet orange) reached West Asia by the time of Ibn Sina (who used it in a recipe), and then in the Middle Ages, the bitter orange reached Europe, where people used it to make marmalade, and North Africa: Albertus Magnus mentioned bitter oranges around 1250
