Top 8 Allergenic Foods that account for 90% of all Food Allergies: (

Milk
Egg
Peanut
Tree nut (walnut, cashew, etc.)
Fish
Shellfish
Soy
Wheat
Children may "outgrow" food allergies to milk, eggs, soybean products and wheat. Please note that a Wheat Allergy is different from Gluten Intolerance! Gluten Intolerance (Celiac's Disease) is never outgrown and must be managed!
Children (and Adults) rarely outgrow allergies to peanuts, tree nuts, fish and shellfish.
What is a Food Allergy and why is it different from a Food Intolerance or a Food Reaction?
The process of any allergic reaction occurs when the body mistakes something like a food or pollen as a harmful and dangerous invader. The body reacts by releasing antibodies called immunoglobulin E(IgE). The IgE in turn prompts the body to release chemicals known as histamines. When the histamines are released, the body reacts by producing symptoms such as runny nose, itchy eyes, a skin rash and in severe cases, anaphylaxis. In a food allergy, the body's immune system is involved.
A food reaction or intolerance does not involve the immune system and often, a food that caused a reaction is easily tolerated at another time. A good example of this is citrus fruits. Citrus fruits may cause a reaction or an intolerance in infants due to the high acidity of the fruit. The infant does not react with an immune response rather the infant reacts with either a gastrointestinal response or a dermatological response. Often times infants who are fed oranges prior to the age of 1 year old will break out in rashes around the mouth or bottom and possibly have tummy cramps.
Another example of a food intolerance is a lactose intolerance. People who are lactose intolerant lack a specific enzyme that helps to digest the sugar (lactose) in dairy products. Infants are often able to digest the lactose in dairy products like yogurt and cheese as the culturing of these products has broken down the lactose.
How to Spot a Potential Allergic Reaction:
Here are several things you might note that may indicate baby has a potential allergic reaction or intolerance to a food.
Sudden loose, diarrhea stools and/or vomiting
Sudden rashes on the skin and bottom
runny nose
hives
Irritability and/or gassiness after a new food/meal
Breathing or other respiratory troubles after a new food/meal
Remember, an intolerance to a food is not the same as an allergy to a food and it's symptoms typically involve trouble within the intestines.
The "4 Day Wait Rule and Allergies:
It is very important to follow the "four day wait" rule when introducing your baby to new solid foods. When you introduce a new food over the course of several days, you are better able to determine exactly how your baby is reacting to that food. This is most important if you and/or your family members have a history of food allergies.
Following the four day wait rule and introducing new foods one at a time will also enable you to easily begin an "elimination diet". If you suspect your infant has had an adverse reaction to a new food, you will have just a few foods to look to as the culprit.
Please note that some of the foods that appear on the list of "Least Allergenic" should not be introduced until a certain age. While these foods may not be allergy causing, there may be other issues that make that food item inappropriate to give to an infant prior to a specific age.
An example of this is honey; honey is not a known allergen however it may contain spores that are botulism inducing. Honey should not be given to an infant prior to one year of age. To learn more about honey, visit our Honey Tips section.
Introduce new foods during the morning or early afternoon. This will enable you to deal with any adverse reactions when your pediatrician is in office. Should an adverse reaction occur during the morning/early afternoon, it will cause the least amount of disruption in baby's fragile routine.
Further, you should always introduce new foods after a nursing or bottle feeding. Your baby still receives his main source of nutrition from either breast milk or formula up to the one year old mark - do not let solids interfere with liquid intake!
