MONDAY, May 21 (HealthDay News) -- Filling up on apples and fish during pregnancy might protect your child from developing asthma and allergic diseases, a new study shows.

Researchers from the Netherlands and Scotland have found that eating apples throughout pregnancy may protect against wheezing and asthma in 5-year-old children, while fish consumption may lower the risk of eczema, an allergic skin condition. The findings were to be presented Sunday at the American Thoracic Society's International Conference in San Francisco.

"To our knowledge, we are one of the first studies evaluating the influence of maternal consumption of so many different foods and food groups during pregnancy on childhood asthma and allergic disease," said study author Saskia Willers, a doctoral student at Utrecht University in the Netherlands.

Previous studies in the same group of children, part of the SEATON birth cohort conducted at the University of Aberdeen in Scotland, found that maternal intake of vitamins E and D, and zinc during pregnancy may also lower the risk of asthma, wheezing and eczema. For this study, the researchers looked at how eating different foods, rather than individual nutrients, during pregnancy impacted these children.

The researchers studied 1,212 children born to women who had filled out food questionnaires 32 weeks into their pregnancy. When the children were 5, the mothers filled out another questionnaire about their child's respiratory symptoms and allergies, as well as a survey about their child's food consumption. The children were also given lung function and allergy tests.

The study found that children of women who ate more apples and fish during their pregnancy were less likely to develop asthma or allergic disease. Specifically, children of women who ate fish once or more a week were 43 percent less likely to have had eczema at age 5 than children of mothers who never ate fish. Those whose mothers ate more than four apples a week during pregnancy were 37 percent less likely to have ever wheezed, 46 percent less likely to have had asthma symptoms, and 53 percent less likely to have had doctor-confirmed asthma compared to children of mothers who ate one or no apples a week.
