The sweet potato, a native of the west coast of South America, arrived in China via the Spanish Philippines. In fact almost all potatoes we have in the world today can be traced back to a single mountain range in present day Chile. Regardless, after the European colonization of the Americas after 1492, the whole world became involved in ...
Because the potato is the ultimate superfood; a human being can receive all their essential vitamins and minerals on a diet of just potatoes and milk. They are also easy and cheap to grow and for this reason potato became the staple food of otherwise poor or declining civilizations after the 16th century. The potato arrives in China.

Sweet potatoes originated in Central and South America. But archaeologists have found prehistoric remnants of sweet potato in Polynesia from about A.D. 1000 to A.D. 1100, according to radiocarbon dating. They've hypothesized that those ancient samples came from the western coast of South America.
The Polynesians probably introduced it in 1100 A.D. (red). While the Spanish (blue) and Portuguese (yellow) brought other varieties from the Americas around 1500. The sweet potato made three independent trips to Southeast Asia. The Polynesians probably introduced it in 1100 A.D. (red).
Rouiller got around this problem by turning to dried sweet potato remains kept in a London museum. Capt.
