In a Whole New Mom guest post called Think Food Doesn’t Affect Behavior? You’ve Got to Read This, I suggested that food may affect your child’s behavior more than you think. The post resonated with many parents and has been shared over 400,000 times. Some weren’t convinced. This post is for skeptical moms and dads who have kids with behavioral problems.
Dear Mom. Dear Dad.
Your child is suffering.
Her child’s unfocused mind prevents her from learning.
child’s struggling brain drives him to tantrums, fights, and meltdowns.
Play dates have made way for sessions with:
– psychologists
– tutors
– psychiatrists, and
– the school principal.
This isn’t a happy situation.
I suggested that your child’s problems might lessen or disappear if you adopt a diet based on real food.
Your response: where’s the science?
You wanted:
– double blind tests
– a larger number of subjects
– more facts and figures.
You claimed that my evidence was anecdotal.
First of all, you’re right. The evidence was indeed anecdotal, but I don’t think anecdotal is a dirty word.
Why Anecdotal Evidence Is Not Always Bad
Consider the tragic story of Ignaz Semmelweiss, a Hungarian doctor practicing in Vienna in the 1840s.
I admit to being just a little obsessed with this piece of medical history.
Distressed at the shockingly high rate of childbed fever in his maternity clinic, he set out to discover the cause. He had a hunch that doctors who performed autopsies and went directly to the delivery rooms to assist birthing mothers might be somehow infecting their patients. To test his theory, he instructed his staff to wash their hands in chlorinated lime before delivering babies.
The results?
The mortality rate dropped dramatically.
April 1847 –18.3% death rate
(He started his hand-washing protocol mid-May)
June 1847 – 2.2% death rate
July 1847 – 1.2% death rate
August 1847 – 1.9% death rate
Dr. Semmelweis produced anecdotal evidence demonstrating that morbidity and mortality rates plunged drastically when doctors washed their hands before attending to their patients.
– Without hand-washing, the mortality rate was high.
– After washing hands, the mortality rate went down.
– They stopped washing their hands and deaths increased again.
The same thing happened in Hungary when he instituted hand-washing in another hospital.
You don’t need to perform complex statistical analyses to see that his protocol saved lives, and many of them.
You’d think that doctors in the Vienna General Hospital, as well as physicians around the country (and around the world), would embrace his protocol.
You’d be wrong.
Semmelweis postulated that invisible particles were causing childbed fever.
With Pasteur’s discoveries about bacteria still two decades away, critics labeled Semmelweiss’ theories as ungrounded.
They lacked robust scientific proof. The medical community basically said his ideas were hogwash.
Who knows how many thousands upon thousands of women might have been saved over those next few decades before antiseptic techniques became accepted practice, had they only accepted the anecdotal evidence?
But no–women kept dying.
So Mom, do I have scientific proof that will satisfy you?
Well yes, there is some, such as this study on the effects of food on children’s behavior published in the highly prestigious Lancet – though probably not enough to convince you that this real food diet can help.
But I don’t think we need studies by scientists with degrees and lab coats to let parents know that it’s ok to feed their kids real food.
The REAL Need for Scientific Evidence
The onus of proof, if it lies anywhere, is on Eggbeaters®–not on the egg.
It’s on the frozen chicken nuggets–not the roast chicken dinner.
It’s on the industrialized margarine–not on farm fresh butter.
So my question is: If eating a clean diet with no food colorings or other chemical additives, a diet lower in sugar and higher in healthy, traditional fats might cure your child, why not just give it a try?
What are you afraid of?
This much I know: Not every learning disability or behavioral problem is caused by food; however, some are 100% caused by food.
Our old friend, anecdotal evidence, shows that for some kids, their problems disappear completely once they adopt a paleo diet. Click to learn what a paleo diet is. This is to say that deep down these kids don’t even have learning disabilities or behavioral issues.
Is this the case for your child? The only way you’ll know is to try.
And if it doesn’t help, you can always go back to the cognitive and behavioral therapists, psychiatrists and psychologists, Ritalin and Adderoll.
These options aren’t going anywhere. They’ll still be available.
But how sad to go this route if your kid is one of those for whom a dietary change would make the problem simply disappear.
Do YOU think food affects behavior? Why or why not?

Ruth is a big fan of the whole foods paleo diet, having regained her health after decades of living with chronic fatigue syndrome.

The global manufacturers of food are under increasing pressure to make food: taste better, look better and last longer. And they can by adding artificial additive, food coloring and preservatives.
Unfortunately the by-product of squeezing all this rubbish in, results in increased behavioral issues in most children. But don’t panic, their friends the pharmaceutical industry have come to the rescue to provide relief in the form of ADHD medication. Please don’t complain its a win win, for two of our largest global industries. And the fact that its not discussed is disgusting. Well Done.
You are exactly right. Thanks for commenting and for reading. It’s all terrible. And adults are having issues too!
Please keep this going! You are a rock star! I LOVE it!!!
great articles! thanks for posting. our family is very nutrition conscious — including as many whole, real foods, fruits, veggies and good sources of protein as possible. gluten free, pretty much sugar free but we allow the kids to choose 2 days where they can have something sweet (of their choice) after they eat dinner. we’ve taught the kids to read labels and look at sugar content. they turned down a bottle of some juice that was given to them because it was 57 grams of sugar (albeit fruit sugar). 57 grams! They are generally both very good kids, good behavior, super focused and do really well in school when peers who eat much differently are really struggling with behavior and focus issues. Anyway…one day, we were traveling and sightseeing and we hadn’t eaten dinner yet but came to a dessert place that everyone has to visit when you are visiting. I decided to let the kids eat ice cream without eating dinner because I’m always the one to say no and I didn’t want to be that person and wanted to see what would happen. It was against my better judgement but we did it. BIG MISTAKE! My 4 year old was an absolute mess. Crying, screaming, lying on the table, really mad, fist pounding. My 8 year old was not too happy either but wasn’t as much of a mess. Regardless of wether the study was “perfect”, or anecodotal, or written in a journal, it is suggestive that what we put into our bodies, really matters. I’d love to see more studies but I already see the benefits at home so I don’t need to see them to make changes. Thanks Adrienne for your website and posting all the information that you do.
You are so welcome. And yes, we have the same problems if we let up. I can’t let up on my own diet much either. Thanks for reading!
I share the same sediments when it come to nutrition. Our extended family thinks we are a bunch of food Nazis, but without watching our children’s nutrition, they turn into monsters. Last day of school, I decided to bike with the kids to the local ice cream shop for ice cream before dinner, since I too normally say no. I thought maybe the kids had outgrown the chaos that would ensue when we ate sweets without anything else in oyt bellies. Low and behold both kids had complete and utter meltdowns out of the blue. Crying screaming yelling hitting. Wow! Good lesson for all of us!
