Acrylamide in my diet
Acrylamide
is a chemical, a building block in making polyacrylamide.
In
generally speaking acrylamide is a copolymer.
During the formation of polymers two or three monomers linked together
forming copolymers and further the copolymers are connected. See on the diagram
Polyacrylamide
and acrylamide copolymers are used in many industrial processes, such as the
production of paper, dyes, and plastics.
Food
and cigarette smoke are the major sources of acrylamide exposure for us.
Asparagine is an amino acid in proteins that found in many
vegetables. When the vegetables, potatoes are heated to high temperature over
120 0C certain sugars and asparagines can form acrylamides. Cooking
methods due to the high temperature; frying, broiling, baking produce
acrylamide in the foods. Potato chips, French fries, burnt toast contain high
level of acrylamide.
Animal testing on
rodents has shown that acrylamide exposure poses a risk for several types of
cancer. A
series of case-control studies have investigated the relationship between
dietary intake of acrylamide and the risk of developing cancers of the oral
cavity, pharynx, esophagus, larynx, large bowel, kidney, breast, and
ovary. However, the
evidence from human studies is still incomplete.
The National Toxicology Program
considers acrylamide to be a human carcinogen.
How can you lower
the amount of acrylamide consumed?
Shortening
the cooking time, boiling or steaming instead frying are much better. Blanching
potatoes before frying, drying in a hot air oven after frying have been shown
to decrease the acrylamide content of some foods.
Eat a
healthy, balanced diet that is low in fat and rich in high-fibre grains,
fruits, and vegetables. Do not forget your daily diet should contain 75-80% of
raw foods.
