None of these foods existed in Europe 500 years ago.Now lets talk about the big change in the world diet 500 years ago, after Columbus and the Europeans went to the Americas.After Europeans went to the Americas,
7、 the diet of the native Americans changed a lot. When the Europeans went to the Americas, they took many new kinds of food with them. The Europeans gave some of the food, the meat, dairy products, and grains to the native Americans and then the native Americans started to use the European food in th
8、eir cooking. As a result, the diet in the Americas today is very different from their diet 500 years ago.

10、ound in the Americas. Little by little, people all over Europe started using the new foods in their cooking, and then the foods spread around the world to Africa, the Middle East and Asia.Some of the new food spread very quickly around the world. One example is the chili pepper. You may be surprised
11、 to know that 500 years ago, the chili pepper didnt exist in many countries that are famous today for their hot and spicy food made with chilies.
