What foods reduce glycoalkaloids?
Peeling, boiling and frying can reduce the content of glycoalkaloids in food. For example, peeling potatoes can reduce their content by between 25 and 75%, boiling in water between 5 and 65%, and frying in oil between 20 and 90%.

High levels of glycoalkaloid are toxic to humans. Acute symptoms, which generally occur 30 minutes to 12 hours after ingestion, include nausea, vomiting, stomach and abdominal cramps, and diarrhoea.
