Deep dives
The Backfire of Peanut Abstinence Guidelines
In the early 2000s, guidelines advised parents to avoid exposing their infants to peanuts, believing that this would reduce the risk of peanut allergies. This strategy, however, led to a dramatic rise in peanut allergies instead of the intended decrease. Research has shown that early exposure to allergens, such as peanuts, actually helps build immune tolerance, contradicting the original recommendations. The failure of these guidelines has sparked distrust in medical advice and raised concerns about the consequences of flawed health policies on future generations.
