Food and nutrient intakes and asthma risk in young adults.

Background: Some aspects of diet are relatively newly recognized potential risk factors for asthma, but the evidence to date is conflicting.

Objective: The goal was to determine whether the food and nutrient intakes of adults with asthma differ from those of adults without asthma.

Design: This was a community-based, cross-sectional study of 1601 young adults ( +/- SD age: 34.

A valid food frequency questionnaire for measuring dietary fish intake.

There is considerable interest in the potentially protective effects of high fish consumption on many chronic diseases. Many epidemiological studies use food frequency questionnaires (FFQ) to quantify usual dietary fish intake, so it is important to validate this assessment against objective markers. The objective of this study was to determine the relationship between plasma percentage fatty acids and dietary fish intake as assessed by a FFQ.
