risk comes from acrylamid

What is acrylamide

Acrylamide is a chemical used to make polyacrylamide copolymers

  Polyacrylamide and acrylamide copolymers are used in many industrial processes, such as the production of paper, dyes and plastics also in the treatment of wastewater,

  They are also found in consumer products precisely food packaging and also some adhesives..

acrylamide in foods?

in Europe and the United States some researchers found that acrylamide appears in certain foods that have been cocked to a temperature max thane 120 degrees Celsius but not in foods prepared below this temperature.

Potatoes and French fries were found to have higher levels of acrylamide than other foods.

The World Health Organization : that levels of acrylamide in food pose a "major concern" and that further research is needed to determine the risk of exposure to food acrylamide

How does the cocking produce acrylamide?

Asparagine is an amino acid that is found in many vegetables, with higher concentrations in  potatoes.

  When cocked to high temperatures in the presence of certain sugars, asparagine can form acrylamide.  

 there is other ways  are exposed to acrylamide? 

cigarette smoke is a source of exposure to acrylamide

Exposure to acrylamide has other sources but is classified secondary to that of food or tobacco,
