The average potato has 0.075 mg solanine/g potato, which is equal to about 0.18 mg/kg based on average daily potato consumption. [ 19 ] Calculations have shown that 2 to 5 mg/kg of body weight is the likely toxic dose of glycoalkaloids like solanine in humans, with 3 to 6 mg/kg constituting the fatal dose. [ 20 ]
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.
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 ...
This poisonous compound is also part of the plant’s built-in “armor” and is found in some nightshades, including the green parts of bell peppers, tomatoes, and raw potatoes.
People feared that it was poisonous like other plants the potato was often grown with in herb gardens, and distrusted a plant, nicknamed "the devil's apples", that grew underground. [25] In France and Germany, government officials and noble landowners promoted the rapid conversion of fallow land into potato fields after 1750.

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 ...
The potato (/ p ə ˈ t eɪ t oʊ /) is a starchy tuberous vegetable native to the Americas that is consumed as a staple food in many parts of the world. Potatoes are underground tubers of the plant Solanum tuberosum, a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile.
