Tea intake and risk of allergic diseases: A Mendelian randomization study based on a European population.

ABSTRACT: Some observational studies have shown that tea has some anti-allergic effects. Nevertheless, the correlation that was observed remains uncertain. We conducted a large sample two-sample Mendelian randomization (MR) study to establish the causal link between genetically predicted tea intake and allergic conditions like asthma, allergic rhinitis, chronic cough, eczema, and atopic dermatitis. In a meta-analysis of genome-wide association data from the UK Biobank, single nucleotide polymorphisms linked to tea intake were found among 447,485 individuals of European descent. Genetic information for asthma, allergic rhinitis, eczema, and atopic dermatitis was obtained from the European Bioinformatics Institute, while data for chronic cough was collected from the UK Biobank.
