Study Links Light Prenatal Coffee Drinking to Lower Allergy Risks
"The study found that children born to mothers who drank less than one serving of coffee a day during pregnancy had a modestly lower risk of eczema - the itchy skin condition formally known as atopic dermatitis - by age 3, compared to children whose mothers reported drinking no coffee."
"The study found no meaningful link between maternal coffee drinking and childhood asthma or hay fever. A food allergy finding was even stronger. Children of mothers who drank one or more servings of coffee a day had a 39% lower risk of food allergy by 36 months."
"Because the study was observational - meaning it tracked people's habits rather than testing an intervention - the results show a correlation, not proof that coffee caused the difference. "Our findings suggest an inverse association between prenatal coffee consumption and childhood allergic diseases, with statistically significant risk reductions observed for atopic dermatitis and food allergy by 36 months of age," the authors wrote."
"The study drew on data from the Korean Children's Environmental Health Study, a nationwide research project that enrolled pregnant women between 2015 and 2019. Participants filled out detailed dietary questionnaires during pregnancy, and their children's allergy outcomes were tracked through doctor and hospital records reported by caregivers at 6, 12, 24 and 36 months."
A study of more than 3,200 Korean mother-child pairs found that lower maternal coffee intake during pregnancy was associated with reduced childhood allergic outcomes by age 3. Children whose mothers drank less than one serving of coffee per day had a modestly lower risk of eczema, also known as atopic dermatitis, compared with children whose mothers reported no coffee. No meaningful association was found between maternal coffee drinking and childhood asthma or hay fever. Food allergy showed a stronger pattern, with children of mothers who drank one or more servings of coffee per day having a 39% lower risk by 36 months. The findings were observational, indicating correlation rather than proof of causation.
