The scientific researches are stating that green potatoes contain high amount of solanine,a poisonous chemical that can lead to diarrhea, vomiting, nausea, headaches and many other illnesses, if consumed by mistake.
The high amount of chlorophyll is the main cause for the green colour of the green potato, and the chlorophyll is basically harmless for the health. But it is more like a signal that the amount of solanine, which is produced at the same time as the chlorophyll, has raised too.
Alexander Pavlista, a professor at the University of Nebraska-Lincon,stated that — a 100 pound man would have to consume approximately 16 ounces of green potato to feelsick.
He also added that the green potatoes were never sent to the market for sale. It is always suggested that potatoes should be stored in dim light and cool places to prevent the production of solanine, and to remove the green areas before its consumption.
