Soaking Potatoes Leads To Healthier Chips
April 2008 - Research published in the Journal of the Science of Food and Agriculture has
found that soaking potatoes in water before frying can reduce levels of acrylamide, a naturally occurring chemical
formed when starch-rich foods are cooked at high temperatures.
Researchers explain that there has been growing concern about the health impact of acrylamide and its
potential carcinogenic effect in animals. The study compared simply washing raw potatoes to soaking them for 30
minutes or two hours before frying and found these measures reduced acrylamide formation by up to 23 per cent,
38 per cent and 48 per cent respectively.
These results were only obtained if the potatoes were lightly coloured rather than fried to a dark
Lead researcher Dr Rachel Burch from Leatherhead Food International commented:
"There has been much research done by the food industry looking at reducing acrylamide in products but less so on foods cooked at home and we wanted to explore ways of reducing the level of acrylamide in home cooking."
A report from the American Cancer Society estimates that 2007 saw over 12 million
new cancer cases and 7.6 million cancer deaths (about 20,000 a day) worldwide. Of these, 5.4 million cases and 2.9
million deaths occurred in economically developed countries, compared to 6.7 million cases and 4.7 million deaths in
Very high doses of
antioxidant polyphenols (commonly found in red wine, fruits, vegetables, and green tea) shut down and prevented
cancerous tumors by inhibiting new blood vessel formation. Conversely, at relatively low doses they play a beneficial
role in cardiac and circulatory diseases by facilitating blood vessel growth.
