Glycoalkaloids are found higher in green, germinated, damaged potatoes and potato peel. Ingestion of glycoalkaloids may cause symptoms such as nausea, stomach-ache, vomiting, and diarrhea and increase the risk of glycoalkaloid poisoning.
Highlights:
Glycoalkaloids such as solanine a natural ingredient found in potato can lead to poisoning in humans. The German Federal Institute for Risk Assessment (BfR) have given few recommendations and measures to prevent the risk of glycoalkaloid poisoning.//
Glycoalkaloids are present naturally in plants such as potatoes. In potatoes, t£\-solanine and £\-chaconine are the dominating glycoalkaloid derivatives. They are found in green, germinating and damaged potatoes and potato peel. These glycoalkaloids are used as pesticides to protect the plant from pest and germ infestation.- Glycoalkaloids such as t£\-solanine and £\-chaconine are found higher in green, germinated, damaged potatoes and potato peel
- Ingesting these glycoalkaloids such as //solanine in potato may affect the health and increase the risk of glycoalkaloid poisoning
- The glycoalkaloid content in table potatoes should not be higher than 100 mg per kg fresh weight
Are Potatoes Good For Health?
Potatoes, when carefully prepared and portioned offer important nutrients and can be part of a healthy diet.

‘Glycoalkaloids such as t£\-solanine and £\-chaconine are found higher in green, germinated, damaged potatoes and potato peel. Ingestion of glycoalkaloids may increase the risk of glycoalkaloid poisoning.’
Ingesting these glycoalkaloids such as solanine in potato may affect the health of a person. Symptoms of minor glycoalkaloid poisoning
- fever
- nausea
- stomach-ache
- vomiting
- diarrhea
- impairment of consciousness
- loss of consciousness (occurs very rarely)
- disturbances in brain function
- breathing problems
- problems in the cardiovascular system
"Although only a few cases of poisoning caused by potato dishes have been reported and documented in the last 100 years, green and strongly germinating potatoes should not be consumed in order to avoid health risks," said BfR President Professor Dr. Andreas Hensel.
Potatoes Aren�t the Villains On Your Plate
Potatoes are often painted as villains for dieters, but a new study has found that the staple food is not that bad after all.

NOAEL (No Observed Adverse Effect Level) - the maximum dose at which there are no undesired health effects.

Potatoes: Best Hope For Potassium And Fiber Missing In Diets
Potatoes are a vegetable that tend to be well-liked by young children and are a good source of potassium and provide 8% of the recommended daily value of fiber.

To avoid higher intake, the glycoalkaloid content in table potatoes should not be higher than 100 mg per kg fresh weight.

Purple Potatoes Could be Used in Primary, Secondary Prevention Strategies for Cancer
There may be several substances in purple potatoes that work simultaneously on multiple pathways to help kill the colon cancer stem cells.

Maintaining a low intake of glycoalkaloids is safe. The BfR suggests few ways to reduce the risk of glycoalkaloid poisoning.
- Potatoes should be stored in a cool, dark and dry place
- Potatoes that are old, dried up, green and germinated should not be consumed
- Snacks which are made from potato peels or containing potato peels should not be consumed
- Green parts and "eyes" in potatoes should be removed
- If consumers prefer to eat skin along with the potato, it is safe to choose undamaged fresh potatoes
- Potato dishes with a bitter taste should not be eaten
- Avoid giving unpeeled potatoes to children
- The water in which the potatoes were boiled should not be reused
- It is best to replace the deep-frying fat for potato products regularly
