European researchers have found that children who grow up on farms have a much lower risk of asthma than others. The conclusion of two large cross-sectional studies is that the exposure to a larger range of bacteria and fungi confers this benefit. Perhaps the diversity of microbes assists in the maturation of a child’s immune system, thus significantly lowering the risk for asthma.
