Food origins play a role in nutrition and sustainability as foods with common geological origins have a greater tendency to survive and be valued by the locals. Importance in food therapy is also involved, as allergies to certain foods can be attributed to race. In this way it`s a part of the local food movement. An example would be lactose intolerance among Polynesians and Native Americans who were not accustomed to breeding cattle as much as Europeans. Combined with seasonal cooking, food origins can be used in predicting the tendency of ingredients to work well together, like wine and cheese or rice and tofu. Some foods have a tendency to develop with predominant civilizations like Chinese herbs in Asia and fertile crescent agriculture in the Middle East. Many culinary fruits have global origins, especially berries, more so than vegetables. Fowl are also common on many different continents, like geese and ducks. Different variations of vegetables can be found on different continents, like yams in Africa and potatoes in South America. Another example would be walnuts in Europe and pecans in North America.
