Is the message from new research which suggests they can lead to significant health problems. The research suggests that eating a large amount of crisps, chips and biscuits during pregnancy can lead to babies with a lower than average birth weight. Acrylamide which is found in these foods can not only harm development but can also lead to babies having a smaller head circumference which can cause adverse effects as children grow up. Babies born to mothers with high dietary intake of acrylamide were found to be around 132 grams lighter than those with a low intake. It seems the advice about what you can and can’t eat changes daily, a little common sense with a healthy diet and everything in moderation seems the best approach.
