Lluis et al. showed that farm milk consumption was inversely associated with doctor-diagnosed asthma at age 4 years (OR: 0.26; 95 % CI 0.08–0.88) and that FOXP3 demethylation at the TSDR region was consistently higher, although no significant, in whole blood of children who had consumed farm milk (median differences for all CpGs, p = 0.08). The gene discussed is FOXP3; the disease is asthma.
