Germinated potatoes and mung bean sprouts are inedible. A toxin called solanine is produced in germinated potatoes, especially in buds. Excessive intake of solanine can lead to nausea, vomiting, diarrhea, headache and other symptoms, and even poisoning. Green bean sprouts turn green because they are exposed to sunlight or other bright light, which leads to the accumulation of chlorophyll. In this process, a toxin called chlorophyllin acid will be produced. This toxin is very diluted in some beans, so it will not cause great harm to human body. High concentration of chlorophyllin can lead to food poisoning and gastrointestinal problems such as vomiting, abdominal pain and diarrhea. So germinated potatoes and mung bean sprouts are not edible.
