Fish Consumption at 1 year old Reduced the Risk of Eczema, Asthma and Wheeze
This August 2019 Norway study concluded that eating fish at least once a week at one year of age was associated with a 28-34% reduction in the odds of current eczema, asthma, and wheeze at six years of age. Cod liver oil consumption at least four times per week at one year of age tended to be associated with a lower risk of allergy-related outcomes at six years.
There were no consistent associations between allergy-related outcomes and fish or cod liver oil consumption by mothers.
The study is conducted using questionnaires and the conclusion is one of association (ie not causation).
The motivation for the study was due to dietary changes in Western diet which mainly involved higher consumption of omega-6 polyunsaturated fatty acids (n-6 PUFAs) and lower consumption of omega-3 fatty acids (n-3 PUFAs) which coincided with the time of increase in allergic disease incidence. Also, there were many conflicting and low-strength studies on fish, early solid introduction for high-risk infants which motivated the researchers to dig deeper into fish and cod liver oil, and to include pregnancy diet in their study.
My daughter with eczema takes fish oil regularly, keeping fingers crossed that they would work even if she has already past one year old!
