What major dietary change is often advocated to address food allergies?

Introducing potentially allergenic foods early is often advocated to help address food allergies, particularly in infants and young children. Research suggests that early introduction of allergenic foods such as peanuts, eggs, and dairy can potentially reduce the risk of developing allergies to these foods. This approach is based on the understanding that the immune system's exposure to these foods at a young age may help it to develop tolerance.

Delayed introduction of allergenic foods can sometimes increase the likelihood of developing allergies, as the immune system does not encounter these proteins early on. Therefore, guidelines from various health organizations advocate for introducing these foods alongside solid foods, typically around 4 to 6 months of age, but under guidance from pediatricians, especially for infants at high risk of allergies.

In contrast, avoiding all fruits, eliminating whole grains, and increasing sugar intake do not align with current recommendations for managing food allergies and do not address the concept of tolerance development in relation to allergenic foods.
