Journal Says No Proof Special Diets Help Autistic Children

New research was released today about children with autism, and it’s sparking a fresh round of intense debate.  The report from a panel of experts finds no scientific proof that digestive problems are more common in children with autism and no evidence that special diets work.  The research, published in the journal Pediatrics, has been met with controversy — many parents say that restrictive diets have helped their children by combating symptoms and behavior problems of autistic children.

Actress and activist Jenny McCarthy’s son was diagnosed with autism, and tonight she tells ABC News that she and many others have seen positive effects from wheat and dairy-free diets.

“We’re the ones seeing the real result,” she said.  “And until doctors start listening to our anecdotal evidence, which is this is working, it’s going to take so many more years for these kids to get better.  Every parent will tell you something different that helped their child, but all we know is that from this community we do see positive changes from this diet.”

ABC News Senior Health and Medical Editor Dr. Richard Besser said the report was important and that it lays out what is known scientifically and what still needs to be studied.

"The main conclusion is that doctors need to be on the lookout for gastrointestinal disorders in autistic children. They can be easy to miss due to the communication problems that these children have," Besser said. "Controlled studies of diets need to be done to determine whether they work — at this point there just isn’t evidence to answer that question.  Children on restricted diets need to be monitored closely for the development of nutritional deficiencies."

This was a terrible and irresponsible story on the broadcast. A brief mention of the study and then a free rebuttal by a person with no scientific or research background, whom everything out of her mouth on the subject has been scientifically dis proven. Where was the discussion of the study itself? Where were the comments of the researchers?
It is this elevating of celebrity faux-science activism over real science that confuses people at best, and subjects children to real harm at worst, that makes it impossible to have a real discussion of the issue.

Although I recognize that special diets do not help every child who is living with Autism…. The experience we had with our own son was profound. We initially changed him to a cassein free diet and it was literally like someone turned on his light switch. In 2 days he was spitting out words he’d never said before. His eye contact came back and he became very affectionate…. All with in one week. He is now on a Gluten Free diet also and all of his digestive issues have resolved. I do not preach to other parents about our own personal methods but when you witness something so profound and so quick you can not help but want to share your story…. You can’t ignore that. I can’t look at another parent in the eye and not tell them what worked for our son. They are broken and desperate…. It would be irresponsible. Like I said, it may not help everyone but if one more parent can finally see their child smile at them, kiss them and call them mommy/daddy… Then it would be worth it. The doctors/professionals want us to believe in them but they need to believe in us as well.

What in the world!!! Jenny McCarthy??? Do you know how many children have suffered because of this her psuedoscientific BS?
I can listen to that claptrap on Ophra.
Putting her rebuttal of a scientific study on TV is tantamount to putting on someone who claims to have seen Elvis last Saturday.
Irresponsible!!!

great bit of news,
it gives us some hope mist our deteriorating healthcare system. did anyone listen to the healthcare debates. everything is controled by the phamacuticals and insurance companies. even some of our representatives in washington.

It was disappointing to see Jennny McCartney on TV like she was some kind of expert on the subject, instead of being just some person people believe because she’s famous.
Who are we supposed to believe- Scientists who can back up their evidence (who also weren’t given as much time as her), or someone who had an experience where whatever “results” she got were caused by something else?

In our case of our daughter and autism,she was diagnosed not once but twice,for a second opinion. Ours started at 4 months old with seizures.At one period in time she was having as much as 2-5 seizures a day on 3 diferent anti-epileptic medications. While in the local childrens hospital in our town she was having a video EEG, they removed her meds to provoke a seizure, but she didnot seize. She sat up in the bed and started playing and talking. After returning her to her meds she started seizing and we stayed for 4 extra days. We have started with chiropractic and naturpathic dr’s and are now starting to make progress after stopping the meds. Now we are going to HEMISPHERICAL INTERGRATION THERAPY and making great progress. What we have learned as parents not DOCTORS that on the GF & Casein free diet our baby is progressing. She is making great eye contact as well as her mobility. She is still somewhat non verbal but can express her wants and desires. Thru detox and adding amino acid and vitamin regiment she is making faster progress. Go with your gut feeling and put it in the hands of GOD, you will see results. Our daughter will recover and live a normal life just like her big sister. Medication is not always the answer!

This is one study with dubious motives and funding versus tens of thousands of rock solid evidence from parents who have successfully implemented this diet. It’s easy being an armchair quaterback: I challenge any of you naysayers to come live with us after my son has gone to grandma’s house and totally gone off the diet (acting like a junkie craving his fix of bread). They wouldn’t make one day. The differences my son exhibits on this diet (and off) are all the evidence I need.

Remember, folks: the plural of anecdote is not evidence.
People like McCarthy are dangerous because they spread misinformation about critical health issues like childhood vaccination and because they propound crank theories with no scientific backing.
I understand that parents with autistic children are desperate for anything they can do to help their children. And it’s possible that many autistic children also have digestive disorders or intolerances that make them uncomfortable and add to the behavioral difficulties they face.
But correlation is not causation. Vaccines do not cause autism. Dairy and gluten do not cause autism. At some point, science is going to find out how to tread autism, but until then, we need to stop paying attention to idiots and cranks trying to capitalize on desperate parents’ pain.

Posted by: Dave Fried | January 4, 2010, 9:04 pm 9:04 pm

To Dave,
Nobody ever said that these vaccines or diets cause autism. However there is plenty of circumstantial evidence that say that it aggravates it. There have been many families that have had success with these diets and I belong to a family that have had such success. What I really find irresponsible is the use of fad science such as this in the media. There is no mention of any of the research details and I bet these so called scientists have never observed the effects of the diet first hand.
We have had proper scientific studies saying that many people on autism cannot properly breakdown gluten or casein causing an elevated level of gluten and casomorphines. This in turn causes behavioural and digestive problems. Urine testing has confirmed this in the case of my brother. Simply taking gluten and caseine out of the diet is the simplest solution and in many cases the most effective. You want facts, go live with somene who is on this diet.

Posted by: Andrew | January 4, 2010, 9:22 pm 9:22 pm

Although this diet won’t cure autism, to say that it doesn’t help is a gross twisting of the facts. There is no good science in this study nor is there any in this article.

Posted by: Andrew | January 4, 2010, 9:28 pm 9:28 pm

You report on an incredibly important study with major implications re autism,and the only person you could find to give an opinion is a professional bimbo,with no scientific credentials. I’m sure you had multiple good options,but chose to aim lower than Fox News and go for the superficial.
This was an insult to your audience.We desrve better ,and I will be looking for a network that respects my intelligence.

quoted from the above article
“The report from a panel of experts finds no scientific proof that digestive problems are more common in children with autism and no evidence that special diets work.”
Funny there is no evidence that special diets don’t work either. I often wonder why… These diets have been around long enough for a full blown clinical study to completed, yet nobody has done this. Why I ask? The answer is quite simple – there is no money to be made in precribing a diet – but if a drug existed that provided similar results you can bet that study would be fully funded and completed so these drug companies could capitalize on the 1 in 100 number floating around today.

It is alarming how many children are being diagnosed with autism. There are many causes … one of which is metabolic. Our grandson whose story was published today by the AP press has a metabolic condition where he is unable to break down protein. Before his diagnosis, he was showing autistic behaviors as well as CP symptoms. Once his diet was corrected, his autistic like behaviors totally disappeared immediately. I am sure there are many causes of autism and they should ALL be considered in order to help these children.

“And until doctors start listening to our anecdotal evidence, which is this is working…”
The fact that Ms. McCarthy can say this without the slightest bit of irony tells me she has absolutely no idea what she’s talking about.
As best said by someone else, “The plural of anecdotal is anecdotals, not data.”
Leave the science to the scientist, not these frauds and charlatans like Ms. McCarthy and her ilk.

At the very least, Ms. Sawyer should have acknowledged the wide-ranging and impressive credentials of the study’s authors. Instead, she immediately deferred to a celebrity mother as a default expert on the subject. Ms. McCarthy’s impassioned emphasis on anecdotal evidence demonstrates a limited understanding of/appreciation for the scientific method.
I greatly admire Ms. Sawyer and wish her the best of luck in her new position. However, I hope that in the future she will not allow her producers to misrepresent celebrity as academic credentials.

How could ABC’s producers allow someone with absolutely no understanding of the scientific method give a non-sensical response based on what…5-6 years worth of “experience” without rebuttal from the authors of the study who have impressive creditials and have dedicated their lives to research. I guess the researchers should have posed for Playboy before they released the results of their study.

Jenny mabbe a bit over top at times but without her celebrity status who would hear the cries of the parents dealing with children with Autism. The diet helped my son greatly and if he goes off the diet we pay for it in the days that follow with behavior issues, diarrhea and skin rashes.
These are the “so-called” prefessionals that tripled the number of vaccines we give our children without real proof of anything and they are funded by the drug companies. Let’s get this straight…I am not saying DON’T vaccinate….but when, why, and how much needs to be looked at. Is it truly a coincidence that the rise in Autism began shortly after the number of vaccinations were tripled in 1990? Think about it….this is the same government that allowed tobacco companies for many years to say there is no connection with cancer and smoking or niccotine is not addicting. Wake up!

Applause @ Linda! Well said *and documented!* Your documentation also proves another valid point: Do you really think parents who implement this diet take only the word of Jenny McCarthy? As with all things with Autism, we go to the ends of the earth researching published research; asking our doctors and other parents; and observing the evidence we live with every day.
I’m constantly amazed at how individuals who have never personally experienced anyone with Autism (especially day to day) suddenly have all the answers and talk about us as *those frantic people begging for an answer* as if the immediate reversals we see with this diet are a fantasy.
What a terrible disservice ABC News provided with this story on both sides of the issue: misconstrued facts with little substance or rebuttal from a myriad of sources. It certainly makes you wonder what ABC’s real motiviation for such manipulative story would come from (especially on the heels of their equally irresponsibly\poorly written article on Kim Peek’s recent death).

My son was lost in his own world until I removed gluten from his diet. I saw an immediate and dramatic result. He made more eye contact, began responding to his name, and dramatically improved his language. I’ve been very skeptical of all biomedical treatments; but I have no doubt that removing gluten from my son’s diet made a huge improvement in his social skills.
There are a very large proportion of Autistic kids with digestive problems. I’m not a doctor, but isn’t constipation or incontinence a digestive problem. Results from a reputable lab show that my son’s body is low in nutrients and minerals even though he’s recieving supplements daily.
I’ve read news articles about this study that state, “digestive issues are not more common in children with autism.” Compared to what? People with Autism comprise less than 1% of our population. Are they comparing the percentage of Autistic people with digestive problems to the percentage of the rest of our population with the same problems?
I’m beginning to feel like most pediatricians have an agenda against any information that shows benefits from alternative treatments. And an agenda against any information that shows that their treatments may have contributed to Autism.
Instead of looking for a way to help people with Autism; it seems like these studies are intended to hinder it.

I agree with all of the parents who have posted success with the GFCF diets…I am one of them. It was the most horrible day in my life when someone told me that my daughter might have neurological problems and might possibly be in the autistic spectrum. In the following days, I read so much that my eyes hurt– I was extremely scared. Then I read Jenny Mc Carthy’s book. I read it cover to cover in one night- crying and laughing all the way through. Her strength and very humanistic, hopeful approach with her son Evan put the wind in my sails to change. I faced the challenge head-on- despite the diet naysayers, despite friends and family thinking I was wrong. It may sound trite, but when I was tired and ready to give up I always pictured myself as Jenny and pressed on. The diet was a difficult transition, but we saw great results immediately. My sister, an autistic child specialist has also noticed dramatic results , both behaviorally and cognitively in my daughter and others just by following the diet for 2 months! What I learned is that when you are a parent and you see a problem, you have to try. You cannot stop trying until you find something that helps. Despite what scientists or doctors or anyone says. I hope you are reading this, Jenny, because you are not a bimbo to me- nor to the people who count. You are an incredibly strong woman and mother and you are a hero to those of us who don’t have the kind of celebrity to be heard like you do. Thank for all that you have done.

Wow — this is what journalism has come to? A shrill woman (Jenny McCarthy — remind me why she is famous?) asking that specialists listen to her? How about all of the scientific studies that have been conducted that are helping us to understand prevalence issues as well as useful v non-useful treatments — do they only count if their conclusions match up with Jenny’s experience?
Parents who believe these diets work should continue them, by all means. Parents who are curious should be aware of the science, and might also want to do their own experiments with their children. In my experience working with parents of children with autism, they feel pressure to provide these time-consuming, unpalatable diets for their children, even though they see little to no change in their kids. Some of them are dying for a way to get off the hook, and this study provides solid relief for them. I will be spreading this news.

Our child had gi problems since one week of age but normal, by age 2 he was autistic. I had heard trying the diet was “Dangerous”. So I did lots of research before we tried it. Three weeks into the Specific Carbohydrate Diet, his speech and motor skills came back overnight. I noticed that my autoimmune symptoms were better on his diet and a year later I was diagnosed with Celiacs and Crohn’s disease. Those who are trying to maintain that the diets don’t help anyone are corrupt and have other motives. SOME OF THESE KIDS AND THIER PARENTS ARE GOING TO GET BETTER ON THE DIET. ANYONE WITH AUTISM, ADHD OR AUTOIMMUNITY should rule out dietary problems. The research is out there, they know people will just read a headline and not look any further. You owe it to yourself and you loved ones to dig further and get the facts.

I am a mom of a 6 year old Autistic boy and who ever says diet doesn’t work they are so wrong…..It may take more time for the actual effects of a diet change to actually work, like in the case of my son where it took almost 3 weeks, but his bad behaviors have calmed down alot with fewer outburst and less screaming than before when everything was to be scream about…if one would consider that some foods act like toxins to the body, much like an allergic reaction, then you can see how food can indeed be a factor in Autism…

Posted by: Cheryl Black | January 29, 2010, 7:21 pm 7:21 pm

My Grandson has autism and switching him to a casin free, gluten free diet made a world of difference. I do not think the medical profession has any interest in making someone well, or they would be all over the possibilities of health through diet. Obviously, the media is bought and sold down the river and does nothing to investigate a story!!
