A total of 30% of visitors to the British Nutrition Foundation's (BNF) new on-line resource for expectant parents are looking for food safety information.
While 24% are searching for advice on how to ensure healthy weight during and after pregnancy, and 12% are looking for facts about alcohol intake.
The progress of scientific research means that advice on some areas of food safety for pregnant women has changed in recent years.
The BNF believes that its new resource will enable expectant parents to arm themselves with up-to-date information on diet, nutrition and physical activity.
Bridget Benelam, senior nutrition scientist at the BNF, said: ‘Expectant parents have a right to reliable, balanced information.
‘Nutrition is a complex science and people can't be expected to keep up to date with the latest advice and make the right choices about food safety, weight control, nutrition and exercise before, during or after pregnancy, without access to facts and expert advice.
‘Unlike printed materials which quickly become out of date, online resources are particularly valuable for parents as they can be easily updated to reflect new scientific evidence and guidelines.’
The information was collected in an online poll from May to November 2011 and a total of 1416 people took part.
