Defining 'gluten-free' — Is it all or nothing?
By Jennifer Nelson, M.S., R.D. and Katherine Zeratsky, R.D.
In August the Food and Drug Administration (FDA) reopened the comment period for the proposed rule on the term gluten-free on food labels. This extension is your last chance to comment before the rule is adopted.
The FDA proposes to allow use of the term gluten-free for foods that do not contain any of the following:
- An ingredient that is a species of wheat, rye, barley or a crossbred hybrid of these grains
- An ingredient derived from these grains that has not been processed to remove gluten
- A processed ingredient derived from these grains that adds 20 parts per million (ppm) or more of gluten
- Any food containing 20 ppm or more of gluten
It may seem contradictory for the agency to say that a food that contains gluten — even less than 20 ppm — is gluten-free. However, analytical methods are not available that can reliably detect lower levels of gluten.
In addition, this level was vetted by an expert panel that examined existing research to determine a "safe" level — the point at which no or few adverse effects occur. It's also important to note that 27 other countries currently use this level. Finally, the FDA has said that it's open to revising the standard in future if more sensitive methods are developed for determining gluten levels.
Some people might be tempted to discount the proposed rule because they feel no amount of gluten is acceptable in a food labeled as gluten-free. However, not adopting some set of criteria means that people with celiac disease will remain in the dark when trying to interpret food labels. Claims such as "made on equipment that shares processing with wheat" or ingredient names such as "wheat starch flour" are confusing and don't provide meaningful guidance.
For those with celiac disease it is critical to have foods with the lowest possible amount of the offending grain — preferably none. Defining gluten-free in a realistic and enforceable way is a good first step.
What are your thoughts? Share them with FDA now — the link appears in the reference list.

This is a big step as glutenous grains are a common food allergy in many people. It is the single most allergy producing food in children. With the industrialization of grains, including the processing and refining that takes place, along with the chemicals, sprays and pesticides that are used on conventional crops, actually poses serious health risks to millions of human beings. Glutenous diets have been shown to promote serious health issues in many people, especially in those with autoimmune or other chronic diseases such as cancer. Many medical doctors are unaware of the side effects of gluten, running test after test with no answers. Hopefully, these such issues will be addressed in the near future as well.

It is all or nothing. If I eat anything that is manufactured in a gluten & gluten-free plant, I get sick.

I have been urging the Canadian government to adopt particular labels for gluten since my diagnosis in 2003. I don't think they get it. I've argued with Members of Parliament, Ministers of Health and Health Department bureaucrats. I still don't think they get it.

Fresh is best . . . Celiacs need beware anything inside a package not made by nature.

I was biopsied in April 2004. I'm 87 years old. I have tried to be super-strict with my gluten-free diet and gluten-free medications. I even avoid licking the glue on envelopes etc. I'm still getting hidden Gluten from somewhere, because my Endoscopies continue to show damage to my Villi. I eat Gluten-Free foods but wonder if those 20ppm can be responsible. Might it be possible to label foods with "Gluten(0)" "Gluten(5)" "Gluten(20)" or some such quantitative value ?

I WAS BORN IN 1943 AND HAD GASTRO PROBLEMS ALL MY LIFE. I WAS SKINNY AND DID NOT GAIN HEIGHT UNTIL 17 WHEN I GREW 8' IN A YEAR. I WAS SICKLY AND SENT TO A PSYCHIATRIST WHO SAID IT WAS ALL IN MY MIND. IT WAS THEN I DECIDED TO DO MY OWN RESEARCH AND CAME UPON CELIAC DISEASE. I TALKED TO MY DOCTOR WHO AGREED THAT I SHOULD TRY THE GF DIET. THIS WAS IN 1976. WITHIN 3 DAYS THE MAJOR SYMPTOMS DISAPPEARED. I HAVE BEEN ON A GF DIET EVER SINCE. I AGREE WITH THE LESS THEN 20PPM STANDARD, AS NOTHING IS PERFECT AND THIS HAS SOME SCIENTFIC BACKING. I WILL NOT EAT OATS REGARDLESS, AS I ALWAYS HAVE SOME REACTION AFTER EATING SAME. THIS MAY NOT BE RELATED TO GLTN INTOL. BUT MAY BE DO TO SOME OTHER FACTOR

I was born in 1943 and diagnosed with celiac disease within a few months. My symptoms were classic: diarrhea, bloating, failure to thrive, etc. and I spent 6 months in the hospital being fed intravenously through my ankles. When released I was placed on a banana diet, with gradual introduction of other foods. Sometimes celiac symptoms came back and other times not. I learned about the GF diet 18 years later, again with the advice to introduce new foods gradually. This diet made for social isolation and a miserable childhood and adolescence.By the time I learned from published research that the diet damaged the intestines even without symptoms, I had become one of the unusual men who have osteoporosis. Let's get this realistic label approved NOW, that nobody else has to go through this needlessly. Please!

Eating gluten-free is required for all those with Gluten Syndrome.....Celiac Disease is just one of over 300 conditions manifested by those unable to tolerate/digest gluten. Even though medical professionals receive minimal nutrition education, it is common sense that what people are eating could make them sick.

Gluten is flavoring, stabilizing or thickening agent. I excluded oats from my diet, Several grains and starch sources are considered acceptable for a gluten-free diet.Gluten is used in ice-creams and ketchups. You can not totally gluten in your diet because gluten is used in our food for different purposes. You can go for caralluma, if you want to lose weight fast.

I have celiac and have been doing everything I know possible to eat gluten-free for four years with quite excellent results. Just recently I have begun having symptoms of a skin condition called DH which plagued my father who went undiagnosed for celiac until he was into his 80's. I have no idea where I must have picked up a trace of gluten to aggravate this condition. I would love to see a complete list of all trace ingredients which may contain hidden sources of gluten. Allergy information which only addresses wheat does not help me at all.

I was diagnosed 3 years ago with celiac sprue and the diet has been a challenge. I agree with some others that eating out can be difficult. My husband was recently hospitilized, and I couldn't believe how little choice there is in the hospital cafeteria for gluten-free diets. I even called the dietician and she suggessted I bring my lunch!!!

Unfortunately, all of this costs companies money - both testing and cleaning in between product runs. So unless they are specifically targeting a gluten free audience to sell to, there really is no incentive for them to do this unless they are mandated to do so. Government mandates bring with them a whole host of issues and expenses that also increase cost and in many cases lower quality in the long run...sadly, it all comes down to money unless it is from a company with a mission to serve the gluten free community!

Why doesnt the FDA test prescription and over-the-counter medications and label them gluten free also? We have wasted money on prescriptions only to discover that they were not gluten-free.

My husband was diagnosed 1 1/2 years ago - what a change in life for us. But as we went along it actually becomes easier, and we live in northern Alberta , far from the easy to get at Gluten free foods. You can order most gluten free stuff over the phone or internet so go searching. We eat better than before and alot healthier. I LOVE the magazine" Living Without" It has been the best thing for recipes and how to adapt my old recipes. One lady who bakes bread in the USA somewhere says to take rice flour, put it in your food processor and beat it down finer - it makes better bread. So go get the magazine. Also this MAyo site is great for new info.

The use of the term "gluten free" seems to be an about face from the current labeling. I have yet to notice a "does not contain" notice on any food product. So, why the exception for gluten. A more effective notice (for the celiac patient) would be "CONTAINS GLUTEN". Since the "Contains" clause is the standard for other ingrediants I suggest that would be the most appropriate and effective. iPerhaps the food industry does not want to discourage the consumption of Gluten.

I think Celiac disease is something that's not commonly known but needs to be put out there. I work with Chef's Diet, and we prepare meals daily that cater to specific people's diets (such as a gluten-free meal plan), and even deliver the meals to your door. I'm happy to see an article out such as this one, helping create more awareness around the subject. Thanks for posting, and if anyone is interested in what we do at Chef's Diet, please visit http://www.mychefsdiet.com. :)

I live in Vancouver Canada & have lots of GF products available. It wasn't that way when I first started about 7 yrs. ago. I also have a soy allergy which is difficult as most GF foods I find have it added. I do alot of baking, creating my own recipies. Some work some not so much. I have managed a bread which is awsome.

As a vegetarian dating a vegan/Celiac's disease prone man, I agree wholeheartedly. This is a lifestyle change and I am very aware of ingrediants even more so now. It can be challenging. I've always enjoyed cooking, but baking is a new mission altogether. I hope the FDA will enforce better standards so the ones we love will not risk getting sick on accident.

Jennifer, Thank you for the great idea on how to make crackers and pizza crust. I will try this soon. I feel fortunate to live in Rochester where there are many places to get GF products. I just happened on your blog today. Thank you!

Why don't restaurants include/ indicate gluten free meals on their menus? Whenever I dine out there is usually only one item on the menu that I can have, and it's the same thing everytime. When I ask the waiter which dishes are gluten free they are unsure even when they check with the chef. Very frustrating.

Just to clear things up -- the gluten-free component of the allergen labeling law does not require companies to label their products "gluten free."' Use of the label will still be voluntary. What it will do is establish, for the first time in the US, specific rules about what can be labeled "gluten free." One of these rules proposes that foods have to have less than 20 ppm of gluten to be called "gluten free." Another proposed rule specifies that products be tested to prove they have less than 20 ppm of gluten, including gluten that might have unitentionally gotten into a product due to cross contamination. Although it is voluntary, there's no doubt the definition will be helpful to those who follow the gluten-free diet, as well as companies interested in making products for them. Now it just has to be finalized.

Hi Susie - I agree, it can be very difficult to find gluten-free substitutes for bread/bread products. I recently found a way to make crackers and pizza crust that my (celiac) husband loves - friends & me too! Select a gluten-free dry mix for pizza crust (one that includes yeast). Mix according to package directions. Make a thin pizza crust: moisten your fingers with water and spread it very thinly (yes thin, not paper thin but very thin) on parchment paper. Lightly brush the crust with oil. Bake at 425 degrees - on the parchment paper only - not on a sheet pan - until almost golden for about 5 minutes. Bring it out of the oven and top with tomato sauce and other favorite gluten-free toppings. Put back into oven to warm the toppings through. NOTE: You can also make crackers - after brushing the crust with oil, sprinkle with herbs (rosemary), or pepper or parmesan cheese. Bake at 425 degrees a bit longer or until crisp/browned. Break apart for crackers. Usually the pizza mix makes lots of dough - I keep what I don't use in a covered bowl in the refrigerator and use it over several evenings. I'm sure others people have some suggestions too?
