A new study shows pregnant women with asthma can reduce their risk of having asthmatic children by eating oily fish. Results show asthmatic mothers who ate oily fish, such as salmon and trout, during pregnancy were about 70-percent less likely to have children with asthma. In fact, researchers say the more oily fish a woman consumed, the less likely her child was to develop asthma. Children with non-asthmatic mothers did not benefit from having their mothers eat oily fish during pregnancy.
However, mothers who ate fish sticks during pregnancy were twice as likely to have children with asthma, regardless of whether they had asthma themselves. Researchers say the reason is fish sticks are deep-fried, and they contain omega-6 fatty acids, which encourage inflammation of the airways. Oily fish contain omega-3 fatty acids, which appear to be anti-inflammatory and lead to the reduced potential for developing asthma and allergies.
