Objective To investigate the feeding, diet and growth of young children with autism spectrum disorders (ASD).

Method Data on feeding and food frequency were collected by questionnaires completed at 6, 15, 24, 38 and 54 months by participants in the Avon Longitudinal Study of Parents and Children. A food variety score was created, and the content of the diet was calculated at 38 m. The feeding and dietary patterns of 79 children with ASD were compared with 12 901 controls.

Results The median ages of ASD children were 28 months at referral and 45 months at diagnosis. ASD infants showed late introduction of solids after 6 months (p = .004) and were described as "slow feeders" at 6 months (p = .04). From 15–54 months ASD children were consistently reported to be "difficult to feed" (p < .001) and "very choosy" (p < .001). From 15 months, the ASD group had a less varied diet than controls, were more likely to have different meals from their mother from 24 months, and by 54 months 8% of ASD children were taking a special diet for "allergy."

ASD children consumed less vegetables, salad and fresh fruit, but also less sweets and fizzy drinks. At 38 months intakes of energy, total fat, carbohydrate and protein were similar, but the ASD group consumed less vitamins C (p = .02) and D (p = .003). There were no differences in weight, height or BMI at 18 months and 7 years, or in hemoglobin concentrations at 7 years.

Conclusions ASD children showed feeding symptoms from infancy and had a less varied diet from 15 months, but energy intake and growth were not impaired.

Re: Pediatrics: Nutrition Doesn't Matter For Kids?

According to this research, kids with autism tend to eat terrible diets, but this doesn't affect growth or nutrition status.

I'm a licensed registered dietitian who has been in practice for more than ten years, working with special needs children. I have quantified food intakes and assessed growth patterns on hundreds of children with autism.

My experience in practice strongly disagrees with this conclusion, but I will leave it to a parent to illustrate with her own quote how preposterous this study’s conclusion is (as printed in The Chelsea Standard (Parents Adjust To Life With Autistic Child ) "...he suddenly stopped talking. He stopped eating any food except for pretzels. Instead, he ate sand, wood and rocks."

The message from Pediatrics on this permits clinicians to conclude that this should trigger no particular concern. It's okay for kids to eat nothing but pretzels, sand, wood, and rocks. No medical intervention required.

Did the research mean to suggest this is only okay for kids with autism? In a fashion similar to how it has become acceptable and too frequent for young school children with autism to be tasered (as in HERE), but not typical kids?

Is this where we are going - classifying children with autism as something other than human?

I've seen eating patterns like this in kids with autism many times. Any classic nutrition text describes "pica". This research even noted that the children with autism had pica at nearly six times the rate of their typical peers – but inexplicably, the authors don’t mention that finding in their discussion or conclusions. Mercury poisoning, lead toxicity, poor zinc status, copper imbalance, or iron deficiency tend to accompany an eating pattern like this, in any child. Pica is not benign; it is associated with poor impulse control and obsessive compulsive behaviors - common features for children with autism - and with dangerous exposures to metals that can injure the brain. This is just one of many nutrition problems I routinely find when I assess children with autism.

In fact, in 11 years in practice, I have never encountered a child with autism who did not have a treatable nutrition problem. They do typically eat extremely limited diets. It isn't unusual for me to see no more than three items on a food diary: "Gogurt x 3; chocolate milk 4-5 cups/day; plain noodles, 1 big bowl" …and this is what a child will have been eating year in and year out. It's no stretch to intuit that this will leave any child bereft of adequate nutrition to learn, grow, sleep, thrive, or behave to their potential. We would never leave a typically developing child on a diet of nothing but literally only coffee cake and milk for years (another example from my practice).

What happens to children who eat like this? My case files illustrate that they get sick more often, become constipated, behave poorly, acquire anemia, acquire deficits of nutrients that impair them functionally, can't focus, don't sleep, and may not grow as expected, just for starters. But now, we can rest assured knowing that this is okay, as long as your child has autism, thanks to this research.

I noted astounding methodology flaws in this paper that let the data show - essentially, nothing. Here's where the study went wrong – the errors are many, and egregious:

1) The study group was disproportionately small compared to the control group: There were only 79 children with autism, but nearly 13,000 typical control children. This diffuses differences that might exist between the two groups. The controls will present such a wide swath of eating patterns as to make any difference with the small clinical group vanish.

2) The authors used a tool called a food frequency questionnaire that mothers filled out. This is a nutrition researcher's weakest instrument for assessing diets. It doesn't actually quantify a food intake. Rather than tell you what nutrients a child is actually eating - how many calories, how many grams of protein or fat, or how much iron or vitamin A daily - it just tells, for example, whether or not a child may have eaten a piece of fruit this week, or not. It is better suited to population nutrition studies, where thousands of food intake records are compared between one population group or another. It is not adequately informative for a study of this type with a small data set of 79 kids, because it doesn't describe what the kids actually ate.

3) The authors mixed diet strategies in the test group. Some children were using special diets, some were not. This is confounding. In practice, I observe that children with autism on special diets eat more nutritious food intakes than those who are nutrition-treatment naive.

4) Food questionnaires were filled out by parents. In practice, I find that parents vary widely for how accurately they report what their kids eat. I routinely facilitate this piece of the nutrition assessment process because parents inevitably make gross errors. This is a tremendous weakness in the only data actually collected by the authors (other data came from pre- existing health records).

5) The authors were allowed to invent then use their own contrivance, something they called a "food variety score". There is no precedent to support that this is a valid instrument or not.

6) The authors refer to growth data but do not include it. BMI is referenced but excluded. I routinely find in practice that children with autism fall into growth regression or growth failure, so I was eager to see this information. The authors instead vaguely state that "Weight and height measurements collected by health visitors as part of health surveillance were extracted from the Avon Child Health Computer database." and "At the age of 7 years, all children in the ALSPAC were invited to a special research clinic at which they were weighed and measured." Were the children with autism anthropometrically assessed or not? Where is the BMI comparison? What is a “special research clinic” (is it like Dr Wakefield’s infamous birthday party?), and were the children assessed, or just invited to be assessed?

7) The authors refer to hemoglobin data but don't include it. I have found many children with autism to be in poor iron status - again, I was eager to read this piece. The data simply isn't there and once more, sweeping conclusions are made anyway. Additionally, hemoglobin status alone is not sufficient to support the statements made here about iron status between these groups. Iron status was not measured; the disparity of size between the two groups is too large to find a difference; and, children with autism who begin diet corrections may correct an iron deficit, thereby further confounding the data.

8) The authors state that energy (calorie) intakes and many nutrient intakes were comparable in both groups. But they never measured these. Energy and nutrient intakes were never actually quantified in the study at all. Note that none are reported either. There is an inane table in the article's appendix that lists several nutrients in a comparison of frequencies of intakes that is oblique at best, invalid at worst. It looks impressive, with a long list of individual nutrients followed by statistical test measures, but it states virtually nothing. Odds Ratio (OR) is not a quantity. This table deceives readers with an impression that nutrients were quantified. The only accession the authors make about this is in the cryptic title of the table: "Details of the Diet of Children With ASDs". What exactly is meant by “details”?

Another "Dietary Comparison" table in the text lists macronutrients, again giving the impression that these were quantified. Again the table only gives statistical test measures, not quantities. Readers are left to simply trust that the authors interpretations are valid; there is no actual data given for us to assess ourselves.

Nutrients intakes were never in fact quantified and compared at all - but the authors make sweeping conclusions anyway about the comparable levels of nutrients eaten by both groups, claiming that there are no notable differences. This appears to be intentionally misleading.

This statement astonished me: "No differences were found between children with ASDs and their peers in the balance of carbohydrates, protein, and fats consumed, which suggests that satiety mechanisms are not impaired in ASDs. No differences were apparent in minerals in the diet, including iron and calcium." Note that the authors gingerly say "balance of" nutrients, not actual amounts of nutrients. Stating that "no differences were apparent" is not valid because measures to quantify differences were not used. Mineral intakes were not quantified, and no one assessed mineral status in signs, symptoms, or lab studies.

Did the authors begin with a bias, then consciously fulfill it with poor methods, to discourage families from approaching nutrition care for children with autism - an approach riddled with controversy? It's an easy argument to make, as the facts in child nutrition prevail here to expose the crippling weaknesses in this work. The medical community can't have it both ways. If a diet of wood, rocks, and sand is bad for a typically developing kid, it's bad for any kid. No amount of busy looking tables can hide bad work - but it's an old trick in the academic press. This appears to be a hastily done study that tapped a large existing data set to make it seem more valid than it is. Shame on Journal of Pediatrics for supporting it. Articles like this one do a tremendous disservice to families grappling with autism who need nutrition screening and care for their children.

Great letter Judy. I hope Pediatrics will print it.

Emond sits on the UK's Joint Committee on Vaccination and Immunisation along with Andrew Wakefield's Royal Free antagonist Brent Taylor and others, which is responsible for dictating vaccination policy according to recent statute. He failed to state this in either this paper or an earlier one (which he also co-authored with Golding and Steer), and it is hard not to see this paper in a blatantly propagandist light: it is always easy to design papers that find nothing:

Thank you Judy!

I am so tired of reading poorly done, ham fisted studies executed by inept scientists who have no understanding ASD/ dietary interventions, are not dietary clinicians, or parents or knowledgeable about our kids. For God's sakes- how low does "Pediatrics" set the bar?

The authors and the editors of "Pediatrics need to enroll in a Statistics 101 class right now. They also need to read a book about actual dietary interventions and autism- Judy Converse, Julie Matthews...I would bet the Edmonds inexpert scientists have been getting their information on this topic via psychiatrists and ancient textbooks.

The Edmonds research serves to illustrate the deep seated ignorance and incompetence among the traditional autism academic community.


That's it in a nutshell and all sewn up. Thanks to Judy for setting the record straight. Too true-- tasering, deadly restraint, solitary confinement in schools, not to mention mass drugging and eating crap have all come under fire when they involve normal children. All the same, they're "just fine" for children with autism. They like it. Just as them. Oh, you can't-- the ones eating rocks especially are too busy screaming.

It's Emonds who's starting to look subhuman frankly. That was obvious when he weighed against vaccine cause in the horrific MMR-induced death of British toddler Georgie Fisher-- rather than recusing himself as the industry insider he is. His junk study is no surprise.

On the other hand, Judy Converse-- insightful, brave, thorough, dedicated-- seems pretty superhuman.


My son has always eaten organic and was breastfed for one year. His eating habits continue to be excellent but he was injected by his pediatrician with a witches brew of toxic crap which inactivated many enzymes in his system. My son had a vitamin a and zinc deficiency from his mercury poisoning. Focuing on diet is a distraction from concentrating on the intentional poisoning of our children.

Yet another reason to fire the useless, stupid, and 100% counterproductive and dangerous pediatrician and find either a GP, family practice, or NP. Practicing medicine should not be lining up kids like Borg drones and seeing how many you can process through your warehouse in one day.

My grandson was diagnosed with failure to thrive for over 2 years. Finally I got him on a very strict SCD and it was all uphill .
He is still at 0-5 percentile in height for his age, but we are waiting for a growth spirt and he is so much healthier now.
Thanks for this piece. It is a crime what the study has done.


What an excellent letter.


Great article. Just one thing, you copied it twice into your post. I agree with your point that if their eating habits are inappropriate, then that should affect their health.
