Acrylamide is a toxic chemical usually found in chemicals and plastics. In 2002 Swedish scientists were surprised to find acrylamide in food; they discovered that acrylamide is found when starchy foods are cooked at high temperatures. This includes everyday food and drink such as chips, crisps, cereals and coffee.
Firstly, does being exposed to these foods in our diet have harmful consequences on human health? Secondly, what is the effect on the unborn baby? We already knew that acrylamide can cross the placenta from the mother to the baby in the womb.
Born in Bradford teamed up with other studies that are similar from five countries (Denmark, Greece, Norway, Spain) to investigate these important questions. We asked pregnant women in each of these countries detailed question about their diet in pregnancy. After the babies were born we measured the amount of acrylamide found in their cord blood.
We found that where the pregnant woman’s diet was high in foods/drinks with acrylamide that had crossed the placenta to the baby there was a reduction in birth weight. This is important because a low birth weight, under 2,500g, is a good indicator of likely infant health in the future. There was also a reduction in head circumference which is an indicator of brain growth.
Our study provides the first global evidence of the harm of acrylamide in pregnancy. There are simple steps people can take to reduce their exposure to acrylamide – avoid overcooking starchy foods and reduce their intake of crisps, chips, coffee and baked cereals. The evidence has informed moves in California to label coffee with health warnings.

Our research has led to UK, US and EU changes in policy and public health campaigns to reduce levels of acrylamide.
Here is how we have influenced changed in the EU:
