What's the Purpose of the Elimination Diet?
Should you try the elimination diet? A lot of people with fibromyalgia (FMS) or chronic fatigue syndrome (CFS or ME/CFS) find that certain foods make them feel worse. Experts believe that because of the central sensitization involved in these conditions, you can develop sensitivities to foods that then aggravate your symptoms.
The best way to figure out what, if any, foods are a problem for you is an elimination diet. It's not an easy one, but it is mercifully short compared to most diet plans. You start out by eliminating broad categories of foods that are the most likely one to cause problems. Then, you re-introduce one at a time and see how you feel.
Research shows that at least half of the people with FMS or ME/CFS get significant relief from symptoms - including pain, fatigue, headaches, bloating and breathing difficulties - by eliminating certain foods. The most common problem foods are corn, wheat, dairy, citrus and sugar, but it varies from person to person.
Before you get started, it's a good idea to make sure this is the right time for you to try the elimination diet. Is a holiday or special event that centers on food coming up? Do you anticipate any major changes or stressors in your life? If so, it's probably best to wait. If not, here's what you need to know:
The Elimination Diet
Even without mental fog, it can be hard to remember what you ate on any given day. That's why a food diary and symptom log are important for the success of an elimination diet. You'll be comparing the two of them to see what effect your diet is having.
Your food diary doesn't need to be anything complicated. A simple list of what foods you eat each day is probably enough. A symptom log can be that simple as well, or you can go to Tracking Your Symptoms to find several sample logs.
Once you start the elimination diet, give it at least five days. If you notice changes in your symptoms that last for a couple of days, you're ready to start adding foods back in. If you don't notice changes, give it another five days. If you still don't notice any difference it's tempting to give up, but if you stick to the diet you may notice subtle changes as you add things back in that can point to food sensitivities.
Foods You CAN Eat
Initially, you'll want to limit your foods to the following (remember, it's temporary!):
- Vegetables (except for corn, peas or beans)
- Fruit (except citrus or any that you currently eat 2+ times a week)
- Meat (except for bacon, sausage, hot dogs or lunch meat)
- Rice and grain alternatives such as amaranth, quinoa and buckwheat
- Bottled or distilled water
- Herbal teas
While it's uncommon, it is possible for people to feel worse when they switch to this diet, probably because they've introduced a new food. If this happens to you, try eliminating anything new you've introduced to see if that helps.
Foods to Avoid
- Dairy products (rice milk is an acceptable alternative)
- Caffeine in any form
- Sugar and aspartame (NutraSweet)
- Wheat, oats, barley and anything containing gluten
- Bacon, sausage, hot dogs and lunch meats
- Peas, beans and corn
- Citrus fruit
- All processed foods
- Anything containing monosodium glutamate (MSG)
- Food colors and dyes
- Any food you currently eat more than twice a week
IT'S ONLY TEMPORARY! Keep in mind that some people with FMS and ME/CFS see pain and fatigue drop significantly when they eliminate certain foods.
Once your 5-10 day elimination period is over, it's time to start adding foods back in. Eat a lot of the re-introduced foods (3 servings a day). You'll want to add one category at a time, then wait 2-3 days before adding another one. Depending on the foods and your body, you could notice an increase in sensitivity-based symptoms within minutes or hours, or possibly the next day.
If you find a sensitivity, eliminate that category again and wait until your body has recovered from the increased symptoms before you add another food.
Life After the Elimination Diet
Some food sensitivities are easier to deal with than others. If you find you're sensitive to wheat, for instance, you may want to see a nutritionist to find out the broad range of foods you'll need to avoid and learn about alternatives. You can also get help managing your diet from About.com's Calorie Count.
If you don't discover any sensitivities, you might still want to maintain the healthier eating habits you adopted for the elimination diet. Read Changing Your Diet to Manage Fibromyalgia & Chronic Fatigue Syndrome for more information on why.
