New foods and the New World
In the last 500 years, nothing about people-not their clothes, ideas, or languages – has changed as much as what they eat. The original chocolate was made from the seeds of the cocoa tree(可可樹) by South American Indians. The Spanish Introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exit today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “potato Famine(饑荒)” of 1845-1846, and thousands more were forced to leave their homeland and move to America.
