Discovering your food sensitivities: how to do an elimination diet
Food allergies vs sensitivities An allergy involves the immune mediated reaction between an ‘antigen’ (usually a protein molecule) and an IgE antibody Allergic symptoms include: hives, watery eyes, sneezing, nasal congestion, skin rashes, swelling of the lips or tongue, trouble breathing, anaphylaxis (rare) Mild allergic symptoms can be alleviated with antihistamines (e.g. Benadryl)
A food sensitivity or intolerance Does not involve IgE antibodies and is not able to be tested for with skin prick testing May involve IgG antibodies but blood testing is unreliable Never life threatening Reactions may include: skin rashes (e.g. eczema), bloating/gas/diarrhea, nasal congestion, headaches, burning eyes, fatigue, joint pain
The ‘gold standard’ An elimination diet is considered the gold standard for detecting food sensitivities

Phase 1 For 3-4 weeks, completely eliminate all of the ‘avoid’ foods Keep a diary- write a short note about how you are feeling each day In general, avoid restaurant meals, sauces, canned soups and pre-packaged foods, as these tend to contain ingredients that may be on the avoid list. In order to obtain accurate information, you must completely, 100%, eliminate all the avoid foods.
Phase 2 After the initial three weeks, you will begin to reintroduce foods on the avoid list into your diet. Choose one food at a time to reintroduce. Eat this food freely for two days, along with all the allowed foods you have already been eating. Continue writing a daily entry in your diary
Phase 2 After two days of adding in a new food, you will either notice no change, or you will notice new symptoms. For instance, you may notice that you are congested, clearing your throat, coughing or sneezing. You may have abdominal cramps, bloating, diarrhea or gas. You may develop a headache or have joint pains. You may feel just generally unwell and fatigued.
Phase 2 If the new food does NOT cause unwelcome symptoms, add it into your diet and go on to add the next new food the following day. If the new food does causes unwelcome symptoms, remove it again from your diet, wait two days, and then add the next new food.
Some foods/food groups can be added back in together Dairy products may be introduced all at once Various kinds of peppers may be introduced together Different types of potatoes may be introduced together

Lentil soup or carrot ginger soup, sliced roast chicken sandwich on toasted rice bread with spinach, avocado and cucumber, carrot and celery sticks

Snacks Allowed fruits and vegetables ½ avocado Apple, banana Carrots, celery, snap peas Rice crackers (read ingredients!) Cookies/muffins made with allowed ingredients
What about supplements? Keep it simple (e.g. calcium and vitamin D) Ensure that the supplements you are taking are free of all of the avoid foods/additives
When you are unsure If you are not sure about whether or not you reacted to a certain food, wait a week or two and try re-introducing it again. Prepare for the fact that some of your favorite foods may make you feel unwell
What to do next… If some of your favorite foods make you feel unwell, don’t despair! Sometimes, the food can be successfully reintroduced into the diet after completely avoiding it for 3-6 months. It may then be possible to eat the food occasionally, in small quantities, without any significant symptoms.
Milk sugar vs milk protein If you discover dairy products bother you, it is possible that taking Lactaid tablets or drops along with milk products may help you. Lactaid will help you to digest milk sugar (lactose). If you have a problem with milk protein (casein), lactaid will not help you.
Gluten intolerance and celiac disease If you discover that gluten containing grains make you feel unwell, you should be screened for celiac disease (a blood test). This test will need to be done after you have been eating gluten containing grains again for several months. Or, you could arrange to be screened for celiac disease prior to doing the diet. NOTE: Some people feel better on a gluten free diet even if they do not have celiac disease
You can choose Doing an elimination diet can give you some very valuable information It is up to you how to make use of the information You may decide to continue to eat certain foods, on some occasions, knowing that you may ‘pay a price’ Or you may develop some new favorites that seem to suit your body
