Green potatoes usually have elevated levels of solanine and should not be eaten in large quantities. Potatoes naturally produce solanine and chaconine, a related glycoalkaloid, as a defense mechanism against insects, disease, and herbivores. Potato leaves, stems, and shoots are naturally high in glycoalkaloids. [citation needed]
The presence of more than 20 mg/100g tuber glycoalkaloids is toxic for humans. [5] There have been instances of fatal poisoning cases from potatoes with high glycoalkaloid content. [6] However, such cases are rare. [7] Some research shows teratogenic effects on humans, but epidemiological investigations have produced conflicting research, as ...
Several are potentially toxic, most notably the poisons commonly found in the plant species Solanum dulcamara (bittersweet nightshade) and other plants in the genus Solanum, including potato. A prototypical glycoalkaloid is solanine (composed of the sugar solanose and the alkaloid solanidine), which is found in the potato.
False, raw eggplants are not poisonous. However, the leaves and flowers of the plant can be toxic. Plants in the nightshade family -- which includes eggplants, potatoes, peppers, tomatoes and ...
Even during food processing, there are several procedures that strip foods of their poisons to make them human-friendly. Check out the slideshow above to learn what common edible contains cyanide ...
Raw potatoes contain toxic glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as food plants like tomato. These compounds ...

The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. The toxin affects the nervous system, causing headaches, diarrhea and intense digestive disturbances, cramps, weakness and confusion, and in severe cases coma and death. Poisoning from cultivated potatoes occurs very rarely, however, as toxic ...
