The elimination diet
To begin the elimination diet for intestinal permeability, avoid all 
known and suspected food allergens.
For two weeks, also avoid all gluten-containing foods: wheat, 
barley, oats, millet, spelt, sourdough, and rye. This includes wheat 
four, breads, taco shells, muffins, cereals, pastries, cakes, pizza, 
crackers, pasta, oatmeal, pretzels, and other four-based products. 
Also avoid all dairy products, including milk, ice cream, cream, 
yogurt, and cheese. Butter and eggs are allowed. 
Don’t drink any sodas (Coke, Diet Coke, Pepsi, etc.). 
Reduce caffeine consumption, including tea (green and herbal tea 
is allowed), coffee, chocolate, and cocoa. The less caffeine intake, 
the better. To help prevent withdrawal symptoms (headaches, 
mood disturbances, and fatigue) slowly wean of caffeine. 
Start by eliminating one quarter of daily caffeine consumption. 
For example: each serving of coffee, soda, diet soda, tea, and each 
chocolate bar equals one caffeine serving. If you consume four 
cups of coffee in the morning, three glasses of tea at lunch, and a 
diet Coke before dinner, you consume a total of eight servings of 
caffeine daily. You should begin by reducing your caffeine serv-
ings by one quarter (which is two servings). So drink six servings 
tomorrow instead. After seven days, reduce your caffeine servings 
by another quarter. Slowly discontinue caffeine over a manageable 
period of time. Not every patient must go of all caffeine; you will 
help yourself if you reduce your intake to no more than one or two 
caffeine servings a day. 
Reintroduction of eliminated food groups
After one month on the elimination diet, start to reintroduce one 
eliminated food group at a time. For example, begin by eating a few 
servings from the gluten group: pasta, crackers, or bread. Then, for 
three days, eat no gluten-containing foods or any other eliminated 
food. Keep a journal handy to note any symptoms that occur.
After three days, reintroduce dairy. Have a few glasses of milk or 
three slices of cheese. Be sure to eat enough servings to let your 
body experience any negative reactions. If after three days of having 
challenged a food group, there’s no negative reaction (headaches, 
stomach pain, bloating, runny nose, congestion, muscle/joint pain, 
low moods, fatigue, etc.), then start to slowly add these items back 
into your regular diet.
If you do experience a negative reaction to any food group within 
three days of challenging it, discontinue that group for another 
month and then repeat the three-day process.
