Hi,
Swedish scientist have found this. If the link comes in to two lines remeber
to paste both parts. I'll add the article here also.

STOCKHOLM (Reuters) - Basic foods eaten by millions around the world such as
bread, biscuits and french fries may have high levels of a substance that
probably causes cancer, Sweden's National Food Administration said on
Wednesday.

Swedish scientists at Stockholm university made the shock discovery while
carrying out research on the effects of cooking staple foods such as cereals,
rice and potatoes, in which they found the substance acrylamide, which
probably causes cancer, the administration said in a statement.

"Fried, oven-baked and deep-fried potato and cereal products may contain high
levels of acrylamide, which is a probable human carcinogen," it said.

"Acrylamide is formed during the preparation of food and occurs in many
foodstuffs...Many of the analyzed foodstuffs are consumed in large
quantities, e.g. potato crisps, french fries, fried potatoes, biscuits and
bread."

The U.S. Environmental Protection Agency classifies acrylamide, a colorless,
crystalline solid, as a medium hazard probable human carcinogen. According to
the International Agency for Research on Cancer, acrylamide induces gene
mutations and has been found in animal tests to cause benign and malignant
stomach tumors.

It is also known to cause damage to the central and peripheral nervous
system.

"Frying at high temperatures or for a long time should be avoided," the
Swedish administration's statement said.

"The discovery that acrylamide is formed during the preparation of food, and
at high levels, is new knowledge. It may now be possible to explain some of
the cases of cancer caused by food," Leif Busk, head of the administration's
research department, said.
