Better growth without acrylamide

Low levels of acrylamide in maternal blood give better foetal growth according to two recent studies from the Norwegian Mother and Child Cohort Study (MoBa). Most acrylamide intake comes from heat-treated food but it can also be found in tobacco smoke and in the environment.

In the first study, the daily intake of was estimated from a dietary questionnaire completed during pregnancy by over 50,000 participants in MoBa. were also taken from a small group of participants to measure acrylamide levels which proved to be consistent with the amount of acrylamide in the diet.

In the other study, levels of acrylamide-like substances in the blood were measured in 1100 mothers and their children in Norway, Greece, Spain, the UK and Denmark as part of the EU project NewGeneris. A clear correlation was found between the levels of acrylamide in maternal and .

Acrylamide affects foetal growth

Both studies found that foetal growth was affected:

(under 2,500 grams) is associated with increased morbidity in infancy. Many studies have also found that children with low birth weight have an increased risk of developing cardiovascular disease and diabetes later in life.

Animal studies have shown that acrylamide affects reproduction, growth and development. As acrylamide is transferred from mother to foetus it is important to study the effects on the child. Since acrylamide is mostly obtained from the diet, other substances in the same food products may be difficult to distinguish in this type of study. Further studies will also investigate whether the combination of different contaminants has more of an effect than individual substances. The effect of acrylamide on factors other than foetal growth has not yet been studied.
