One ABC method of testing is very simple. Take the suspected food or foods and completely eliminate them 100 percent from your diet for just one week. It must be at least 7 days because on the second and third day you may even feel worse from withdrawals of the food allergens or toxins (We can safely call them toxins if you cant process them properly). Anything that your body cant process properly is toxic to your body and will cause little to extreme damage (From rashes to death). I would recommend doing the elimination diet this way. I would take any suspected food allergens and also the top 7-8 known food allergens and be sure non of these are byproducts in other foods that you may be eating. It must be eliminated 100 percent to get the results you seek weather it bothers your system or not. So after 7 days of completely eliminating these suspected food allergens you may on the 8th day beginning first thing that morning choose just one of the suspected foods and have a healthy serving,and continue eating healthy serving for the next 2 days.If there are no signs of irritation, constipation, bloating, headaches, brain fog or feeling sluggish or moody then on the third morning you may move on to the next food item that you wish to have in your diet and repeat part one. Eats lots of it for 2 days and on the third morning if you wake feeling fine then on to the next food source. You can repeat this process until you find a bad reaction.
Food allergens can give you a response within minutes of ingesting them and up to 2 days from accumulative affects of what the body can process properly. If you feel sick or uncomfortable immediately stop and leave out that food source. You may try it again at the end of the list. If it makes you so sick you may have to wait 3-4 days till you can try the next food source. If your feeling great but still notice a little discomfort after eating or any signs of I.B.S. or bloating then you may repeat the test and include new other top known food allergens and repeat the same process.
If a food for sure gives you a bad reaction then most likely it will need to eliminate it permanently from your diets. Here are some of the top food allergens, MILK, WHEAT, GLUTEN, PEANUTS, SHELLFISH, EGGS, SOY, SESAME, TREE NUTS, FISH AND CELERY. These will cover most of your allergy sufferers. There are hundreds of known food allergens but the rest are more rare and if necessary we will take you through them all. Even food coloring and flavoring like caramel and sweetners. In most cases if one has a food sensitivity its most likely he or she will have others. Refer to Feingold elimination diets for more information. His is the most extensive of them all. They will include things you never even new existed like phenols, amines and salicylates and dyes.
So the body does not lie. If you eliminate something and you feel better then reintroduce that item and feel sick again its a no brainer people. Listen to your body and you may also be able to eliminate some doctors!
