Apples and fish sound like and unlikely food combination. However, new evidence has suggested that these two foods can protect unborn children against allergic diseases.
Researchers found that children whose mothers ate a lot of apples when pregnant, were less likely to have suffered from wheeze or been diagnosed with asthma by the age of five.
Similarly, the children of those mothers who ate fish once or more a week during pregnancy appeared to be protected against the skin allergy eczema.
Scientists believe that the effects may be due to powerful antioxidants in apples called flavonoids and omega-3 fatty acids in fish.
When a range of other foods studied including vegetables fruit juice, citrus and kiwi fruit whole grains, dairy fat and margarine, did not produce the same effects.
The investigation was conducted at the University of Aberdeen in Scotland. Researchers studied 1,212 children born to women who had filled out food questionnaires during their pregnancy.
When the children reached the age of five, the team questioned the mothers about their offspring’s respiratory symptoms, allergies, and diet.
The children were also given lung function and allergy tests.
Children whose mothers ate the most apples were less likely to have experienced wheeze or asthma than those whose mothers had the lowest apple consumption.
Mothers who ate fish once or more a week while pregnant had children who were less likely to have had eczema than children of mothers who never ate fish.
