Allergy Concerns: Dietary Guidelines for Infants with Allergic Parents - Pediatrics

Suspected allergic child, seeking advice on dietary issues?


Hello, doctor~~ Both my husband and I have allergic tendencies, and my daughter is currently 7 and a half months old.
The pediatrician advised us not to introduce any protein foods, including eggs, meat, and fish, before she turns one.
I would like to ask if I can use kombu or kelp to make broth for her.
Is it also not allowed to use broth made from pork bones? Additionally, is it true that she cannot eat any type of fish, including "non-allergenic fish"?

Xiao Hui, 20~29 year old female. Ask Date: 2007/04/30

Dr. Pei Rensheng reply Pediatrics


Hello: (1) If both parents have allergic tendencies, the likelihood of their children having allergic conditions is between 60-100%.
The later a child is introduced to protein-rich foods, the less likely they are to develop allergic diseases in the future, especially with seafood.
(2) Broths made from large bones, kombu, or kelp have low allergenic potential.
Following the principle of introducing complementary foods, only one new food should be added at a time to monitor for any symptoms such as diarrhea, rash, or vomiting.
If none of these symptoms occur, it is safe to continue adding new foods.
(3) Seafood is more likely to cause allergies, so it is best to wait until the child is one year old before introducing it.
Wishing you health and happiness! Sincerely, Pei Ren-Sheng.

When it comes to introducing solid foods to infants, especially those with a family history of allergies, it is crucial to proceed with caution. Your pediatrician's advice to avoid introducing potential allergens such as eggs, meat, and fish until your daughter is one year old is a common recommendation for children at risk of developing allergies. This approach is based on the understanding that early exposure to certain allergens may increase the likelihood of allergic reactions in susceptible individuals.

Regarding your question about using kombu (kelp) or seaweed to make broth for your daughter, it is generally considered safe to introduce these foods as they are not known to be common allergens. However, it is essential to ensure that the broth is well-prepared and does not contain any additional ingredients that might pose a risk. The same goes for bone broth; while it can be nutritious, you should ensure that it is made without any added spices, salt, or other potential allergens.

As for fish, the recommendation to avoid all types of fish, including "not-la fish" (which I assume refers to a specific type of fish), is typically advised for infants with a family history of allergies. Fish can be a common allergen, and introducing it too early may lead to sensitization. However, some studies suggest that introducing fish around 6-12 months may actually reduce the risk of developing fish allergies, but this should be done under the guidance of a healthcare professional, especially in your case where both parents have allergies.

In summary, here are some dietary guidelines for your daughter, considering her family history of allergies:
1. Avoid High-Risk Allergens: Continue to avoid introducing high-risk allergens such as eggs, dairy, peanuts, tree nuts, fish, and shellfish until she is at least one year old.
2. Introduce Low-Risk Foods: You can introduce low-risk foods such as fruits, vegetables, and grains. Start with single-ingredient purees and observe for any signs of allergic reactions.

3. Monitor for Reactions: When introducing any new food, do so one at a time and wait for about three to five days before introducing another new food. This way, you can monitor for any adverse reactions.

4. Consult with a Specialist: If you have concerns about your daughter's diet or if she shows signs of allergies, consider consulting with a pediatric allergist or a registered dietitian who specializes in pediatric nutrition.

5. Nutritional Balance: Ensure that her diet is balanced and provides adequate nutrition for her growth and development. If you have concerns about her weight or growth, discuss this with your pediatrician.

6. Hydration and Broths: Using kombu or seaweed to make broth can be a good way to introduce flavors and nutrients, but ensure it is done safely. Bone broth can also be beneficial, but again, ensure it is free from allergens and additives.

In conclusion, while it is essential to be cautious with introducing new foods to your daughter, there are still many nutritious options available that can support her growth and development. Always consult with your healthcare provider before making significant changes to her diet, especially given your family's allergy history.
