However, case reports of solanine poisoning and one toxicology study in humans can provide a good idea. It seems that ingesting 0.9 mg/lb (2 mg/kg) of body weight is enough to cause symptoms, although 0.6 mg/lb (1.25 mg/kg) could be enough to make some people ill ( 4 ). 7 сент. 2017 г.
How much solanine is too much?
It is suggested that doses of 200–400 mg for adult humans can cause toxic symptoms (20–40 mg for children). Most commercial potatoes have a solanine content of less than 0.2 mg g−1. However, potatoes that have been exposed to light and have started to turn green can show higher concentrations.
How much solanine is lethal?
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. 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.
How much green potato is toxic?
Solanine is considered a neurotoxin, and ingestion by humans can cause nausea and headaches and can lead to serious neurological problems and even death if enough is consumed. A recent study suggested that a 16-oz (450-gram) fully green potato is enough to make a small adult ill.
What happens if you eat too much solanine?
Reports of potato poisoning state that unripe, sprouting, or green potatoes contain toxic alkaloids, including solanine. When ingested, they can cause drowsiness, weakness, apathy, and gastrointestinal symptoms. This is rare — in most cases, potatoes are safe to eat and are a staple food in many countries.
