Is it poisonous to eat potatoes raw?

You cannot eat it raw for the following reasons: \ x0d \ x0d \ 1. Starch-rich vegetables (such as potatoes, taro, yam, etc. ) must be cooked, otherwise the starch granules will not be broken and the human body cannot digest it; \x0d\\x0d\2。 Vegetables containing some harmful substances, such as seeds of leguminous vegetables and potato chips, contain a kind of toxic protein called lectin, which can agglutinate red blood cells in human blood, and even cause nausea, vomiting, diarrhea and even death in severe cases. When cooked thoroughly, toxic protein will lose its toxicity and be safe to eat. \x0d\\x0d\ In addition, it has been reported recently that American scientists have found that vegetables commonly used by people, such as tomatoes, potatoes, eggplant and cauliflower, contain trace amounts of nicotine after long-term research. If these vegetables are eaten raw without cooking, they may be harmful to human body, just like passive smoking. In fact, this is not the latest discovery at all. This research report first appeared in a medical journal in August, 1993. Later, because many experts questioned the results of this study, they did not further study whether eating raw vegetables was harmful to nicotine. But the consensus of experts is that the nicotine intake of human body is too "insignificant" to cause medical reaction, and it will not endanger health. We can ignore this reason. If we consider him, we will have nothing to eat.
