Answer each question as best you can and feel free to estimate if you are not sure, as a guess is better than leaving the answer blank.

The data will not be shared with others.

This 7-question food frequency questionnaire was developed by DSM Nutritional Products and adapted by Dr. Susan Carlson and her team of Nutrition Scientists at the University of Kansas. The questionnaire has been validated in pregnant women residing in the Midwest United States and is currently used as a screening tool early in pregnancy at the University of Kansas Medical Center to identify pregnant women at high risk of preterm birth due to low DHA intake.1,2
