The “4 Day Wait Rule”– waiting a few days before introducing a new food
It is really important to follow the „4 Day Wait Rule“ when you start feeding your baby with new solid foods and you need to be even more careful if your family has a history of food allergies. During these days, you will be able to understand how your baby is reacting to particular food. If you suspect that your child has had an adverse reaction to a new food, you will have just a few foods to look to as the reason for that.
You should introduce new foods during the morning or early afternoon because if there is a negative reaction, you can go to the pediatrician immediately.
Here are several things that may show that a baby has a potential allergic reaction or intolerance to a food.
- Diarrhea and/or vomiting
- Irritability after a new food
- Sudden rashes on the skin
- Breathing problems after a new food/meal
- Swelling of the Face, Lips, and/or Tongue
- Runny Nose
Any allergic reaction starts when the body reacts to a food or pollen like there is a „harmful invader“. Then the body releases antibodies called immunoglobulin E (IgE). The IgE makes the body release chemicals known as histamines. After that, the body reacts by producing symptoms such as a runny nose, itchy eyes, a skin rash and in worse cases, anaphylaxis.
What is a Food Reaction or Intolerance?
Food intolerance is not the same as food allergy and its symptoms typically involve problems with the intestines.
Lactose Intolerance – People who are lactose intolerant lack a specific enzyme that helps to digest the sugar (lactose) in dairy products. This is an anomaly of the organism which causes abnormal physiological reactions like abdominal cramps, bloating and vomiting, which are far from being severe. You also need to know that being intolerant to lactose doesn’t mean that you should never consume dairy products because, for example, yogurt doesn’t contain a lot of lactose, which makes it easier to digest. And on the other side, people who are allergic to dairy products are not allowed to consume them.
90% of all Food Allergies are caused by these foods:
- Tree nut (walnut, cashew)
Children may “outgrow” food allergies to milk, eggs, soybean products and wheat. But you must remember that Wheat Allergy is different from Gluten Intolerance. Gluten Intolerance (Celiac’s Disease) can’t be outgrown and must be managed carefully. Also, children (and Adults) usually don’t outgrow allergies to peanuts, tree nuts, fish, and shellfish.
|MOST LIKELY TO CAUSE AN ALLERGIC REACTION||LEAST LIKELY TO CAUSE AN ALLERGIC REACTION|
berries (not blueberries or cranberries.)
|cinnamon (may cause rashes)||avocados|
|citrus fruits (acidic)||barley|

NOTE: This list is general; it is not based on allergenic levels
Some of the foods that are on the list of “Least Allergenic” should not be introduced until a certain age. They may not be allergy causing, but there are some other issues that make that food inappropriate to be given before a specific age. Honey is a good example – Not a known allergen but it may contain spores that are botulism inducing. Honey should not be given to an infant before one year of age.
Janice M. Joneja has developed an allergen scale (often referred to as the Joneja Food Allergen Scale), that has proved to be useful as a comparative measure of the allergenicity of foods.It is based on the frequency of reactions in people eating a typical Western Diet. The foods are listed from the highest to the lowest allergenic and are divided into specific categories of allergenicity.
