If you have eczema or atopic dermatitis, managing your triggers and keeping your skin moisturized are key. Food allergies, such as those to peanuts, eggs, and fish, can sometimes trigger eczema flare-ups. An elimination diet, which involves avoiding certain foods to identify triggers, might help. However, not everyone with eczema will benefit from this approach. It's essential to consult with a healthcare provider, such as an allergist, to determine if an elimination diet is suitable for you. While it can help identify food triggers, it also carries risks like nutritional deficiencies and increased sensitivity to foods. Common food triggers include milk, eggs, soy, wheat, and peanuts. Always seek professional guidance before starting an elimination diet.
