Another cross-sectional study found no DNA methylation differences between infants sensitized and not sensitized to peanuts, eggs, or cow’s milk [34], whereas a recent cross-sectional study reported significant correlations between the nutrient intake of children and the methylation pattern of genes related to obesity (nuclear respiratory factor 1 [NRF-1], fat mass and obesity-associated [FTO], leptin receptor [LEPR] genes) [35]. The gene discussed is NRF1; the disease is obesity disorder.
