Phased Reintroduction

Reintroduction

The reintroduction phase of the elimination diet involves gradually reintroducing one food at a time to identify potential trigger foods. Here are the specific instructions for the reintroduction of foods.

Choose one food

Begin by choosing one food that you want to reintroduce, such as dairy products, and make sure to select the purest form of that food, free from additives, preservatives, or flavorings.

Start with a small amount

Start with a small amount of the food in the morning, such as a teaspoon of milk or a small piece of cheese, and consume it on an empty stomach. If you don’t notice any symptoms after 24 hours, then eat two larger portions the next day. Monitor symptoms and/or triggers for 2 additional days.

Monitor your symptoms

Symptoms that can be associated with a food reaction include headaches, digestive upset, skin rashes, joint pain, and fatigue.

Record your symptoms

Keep a detailed record of any symptoms that you experience, including the type of symptom, the time it occurred, and the severity of the symptom.

Proceed with caution

If you do not experience any symptoms, you can assume that the food is safe for you to eat. However, if you experience mild symptoms, you may want to try the same food again in a few days to confirm that it was the food that caused the symptoms. If you experience severe symptoms, such as anaphylaxis, seek medical attention immediately.

Wait before reintroducing another food

Wait he full 48 hours before introducing another food. This allows you to determine if the symptoms you experienced were due to the food you reintroduced or something else.

Repeat the process

Repeat this process with each of the foods that you want to reintroduce, until you have identified all of your trigger foods.

Keep a food journal

It’s essential to keep a food journal during the reintroduction phase, to help you track your symptoms and identify your trigger foods. If you experience severe symptoms, such as anaphylaxis, seek medical attention immediately. We will look at a sample journal later in the course.

Day 28 – Shellfish

Potential Reaction/Symptoms

Reactions can include a variety of symptoms and vary from person to person:

• Gastrointestinal issues – constipation, diarrhea, gas, bloating, abdominal pain
• Fatigue
• Mood issues – depression or anxiety
• Headaches
• Aches and pains in joints and muscles
• Skin issues – eczema, rash, itchy skin, flushing
• Nasal or sinus congestion
• Sleep disturbances

If a food does provoke a reaction, continue to avoid that food for another three to six months before attempting the reintroduction process again. Consult with your physician if it was a severe reaction.

In the event that symptoms are not resolved after an elimination diet, assuming other pathology has already been ruled out, it may be appropriate to explore other possible sensitivities to foods that contain histamines, nightshades, salicylates, or oxalates.
