Citation? I think there might be a bit of "telephone game" happening here. The current science shows that avoiding allergens increases the risk of developing allergies. The hypothesis for how that happens is that if an infant's first exposure to an allergen is on their skin (e.g., peanut oil), then their body may classify it as invasive and develop anti-bodies to attack it. If they are first introduced to an allergen as food, then their body classifies it as food. By avoiding feeding allergens to infants, you increase the time window for their bodies to be exposed through the skin and classify it as invasive. I could certainly see this idea transmuting through word of mouth into the "first world is too clean" idea in your comment, but that's pretty far off. |
