I heard that when there is no food, people eat sweet potatoes. Can sweet potatoes be a staple food?

    Sweet potatoes can be used as staple food. The same applies to yam, taro, and sweet potato. The above potato foods are the staple food, only need to use a 4:1 ratio, that is to say, eating 3 to 5 pounds of potatoes is equivalent to eating 1 kilogram of rice starch. Because potatoes have too much water after all, they cannot be directly compared with dry rice.
