Beware of Post's Fruity Pebbles Cereal, It is Not Free of Gluten!


Mistikl9

Recommended Posts

Mistikl9 Newbie

Hi, I recently bought a fruity pebbles cereal to my 11 y/o daughter, who is celiac, and I was a little worried about it having any cross contamination as it's not a certified gluten free product. Nevertheless, I decided to let her have some (since non of the ingredients listed contain gluten) and waited for her body to respond. She usually gets a headace and starts getting nauseous if she accidentally eats someting with gluten (which is what always happened before we knew she was celiac). So she ate her bowl of fruity pebbles and after a few minutes, she was fine, no discomfort at all. She was very happy she actually could have it since she really likes it. She continued eating it either as a snack or as breakfast during the same week we bought it, but it wasn't until the fourth day after having it as a snack when she started having a headache. The headache got stronger each hour. It lasted the whole afternoon and stayed through the night. I gave her ibuprofen to help ease the pain, but nothing. She couldn't sleep, and then at around 3:30 am, she started getting nauseous and started to vomit the fruity pebbles. The headache started getting better and she finally could fall asleep almost at 5am. 

I read in a celiac specialized website that some food colorings, depending on where they are made, can contain gluten ingredients.  Maybe that is what makes fruity pebbles unsafe for celiacs. I know parents should be aware of the risk of cross contamination and not trust the plain gluten free labels if the product is not Certified gluten-free, but these products should not be labeled as gluten free or listed in gluten free foods lists anywhere, especially when it is not for certain the amount of gluten it may be contaminated with, or cross-contaminated with.

I hope this message can help anyone who may not know much about how even a small amount of gluten can, and will, affect a person with celiac desease, not because of the vomit or the headache, but in the long run as consuming gluten can cause a person with celiac disease to develop other health issues including developing another auto immune disease such as Lupus or MS (multiple sclerosis). 

Be careful, don't trust companies' misleading labels!

Of course it's possible that there could have been a problem with a batch, but it's unlikely. Large companies tend to do a better, and not a worse job, of making sure that their products are gluten-free, once they decide to add "gluten-free" to their label, and this is due to their larger liability. 

However, her reaction could also could be related to the tons of other unhealthy things in that cereal, including but not limited to the high sugar content, food colorings, flavorings, etc. Really, it's more or less junk food so probably nobody should be eating it. 

So, if you quit eating it because you think it might not be gluten-free then you've likely made a healthier choice, whether or not it's true.

Mistikl9,

I am sorry to hear about what happened with your daughter.  

I've had something similar happen.  I was on the AutoImmune Paleo Protocol diet (which promotes intestinal healing) and decided to expand my diet to include basmati rice and quinoa.  I got sick with headaches and upset tummy.  So, I'd go back to the AIP diet and after a few days, I'd feel a bit better. 

I did some investigation to find out why this was happening.  I learned about "high calorie malnutrition" which is eating too many carbohydrates without enough Thiamine, vitamin B1, at the same time.  Thiamine is needed to turn carbohydrates into energy.  

I learned that the AIP diet can be deficient in thiamine.  I was not getting enough thiamine from the food choices I made that were allowed on the AIP diet.  

I am also a type two diabetic who controls blood sugar levels through diet.  I recognized that the headaches after eating more carbs was due to high blood sugar levels.  My blood glucose meter confirmed this.  High blood sugar levels can happen even if you are not diabetic.  

I believe when I tried to eat lots of carbohydrates, I suffered from this high calorie malnutrition.  I did not have enough thiamine to process the sudden increase in carbohydrates.  I began supplementing with thiamine and have corrected that deficiency.  I can now eat additional carbohydrates like rice chex and quinoa and basmati rice without a problem.  

Be aware that while gluten containing products are required by law to be fortified with vitamins and minerals, no such requirements are made on their gluten free counterparts.

Checking for and correcting vitamin and mineral deficiencies in newly diagnosed Celiacs is part of follow up care.  The damage to the intestines caused by celiac disease causes an inability to absorb the proper amounts of vitamins and minerals.  You may want to discuss vitamin and mineral deficiencies with your doctor.  

This is not medical advice.  I am relating what happened with me.  

Here's some studies about high calorie malnutrition that I found helpful.

The Malnutrition of Obesity: Micronutrient Deficiencies That Promote Diabetes

"Thiamine is virtually absent in food products containing refined carbohydrates such as milled rice and simple sugars, yet the metabolism of these foods requires relatively high amounts of thiamine and may lead to depletion [74]. In subjects on thiamine deficient diets, total body thiamine stores can be depleted within 2-3 weeks [74]."

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3313629/#!po=28.4314

 

Thiamin(e): The Spark of Life

"High calorie malnutrition, due to excessive ingestion of simple carbohydrates, is widely encountered in the U.S.A. today. Thiamin deficiency is commonly associated with this, largely because of its cofactor status in the metabolism of glucose."

https://pubmed.ncbi.nlm.nih.gov/22116701/

 

Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults

"Despite the availability of dietary thiamine in wealthy countries, thiamine deficiency represents an important and usually overlooked issue. In developed countries, the predominant use of industrial food processing often depletes thiamine content along with other vitamins and nutrients. An increased consumption of processed food in the form of simple carbohydrates, not supplemented with adequate levels of thiamine, has been named “high calorie malnutrition” (7, 8). Thus, despite the caloric density, the diet is often of poor nutrition quality and does not meet recommended dietary guidelines for micronutrient intake, making this an at-risk population for micronutrient malnutrition (8). ...This condition highlights the fine balance between adequate caloric intake and balanced nutritional diet. As thiamine is a key factor in the metabolism of glucose, an increased carbohydrate intake will proportionally increase thiamine’s dietary demand (a minimum of 0.33 mg per 1,000 kcal) (1). Thus, rather than focusing on thiamine’s RDA, it is critical to match its intake with carbohydrate consumption as well as total caloric intake."

I hope this helps.

It looks like Fruity Pebbles has 35% of the daily thiamine RDA.  But it also has canola oil which can be hard to digest for some people.

It is simpler and better to avoid all processed foods for 6 months or longer after going gluten-free.  You spend less time reading ingredient labels and worrying about cross contamination etc if you stick with whole foods instead.  Another gotcha for some people is oats and dairy.  Bacon and eggs is a safer and healthier breakfast IMHO.  If you have an Aldi near by they do sell some gluten-free wraps that are good.  Mission corn tortillas are also a sub for bread.

Knitty Kitty, thank you so much for your advice and all the helpful info. I will definitely discuss this with her nutritionist, maybe she is missing some important vitamins since her diet is limited and, as you said, most gluten free foods don't have the same fortified nutrition requirements as the other foods do. Take care ?

GFinDC, yes you're right, It's better to stick with whole foods, bacon n eggs for breakfast, etc. I never even buy those sugar loaded cereals, but this time I gave in to her petition and decided to satisfy her craving. The good thing is she won't want to eat it again, which is the best way to go.

Thanks for the advice ?

Consider subscribing to the Gluten Free Watchdog.  They test products.  It is kind of a mini “Consumer Reports” for those who need to be gluten free.  They have tested many products and out of those about 98 or 99% are labeled correctly and are safe for celiacs.  I love it!  

Of course, each celiac has some uniquely individualized intolerances and new celiacs have  guts often so damaged, eating anything can irritate it.  Consider keeping a food and symptom journal.  Know too, that some celiacs are super sensitive, so you are both going to have to figure that one out.  

Finally, do not forget that we can pick up a virus or get food poisoning just like everyone else.

The problem with Gluten-Free Watchdog is that you have to pay to get the information, and any test they run may show that the product is Gluten-Free at the moment they test it. However, they cannot test a large enough samples of any product to ensure year around safety. They give you a false sense of security. Maybe the box on the shelf right next to the one they picked to test contains gluten, but the one they picked does not. 

You can get free results from the Nima Sensor app, and the thousands of people who have this device run tests over and over and over on the same items, so you get many more results on the same items.

That is why I also don't recommend the Fruity Pebbles.

      no argument. Never take the pills sold for Nuclear events, except in a nuclear event when instructed to by authorities.  Some of these go up to 130 milligrams per pill. 5000 times the strength of the dietary supplement.  130 times the safe upper limit.  130 mg = 130,000 mcg. Dietary supplements like Lugol's Solution and Liquid Iodine are 50 micrograms per drop.  It takes 20 drops to reach the safe upper limit. In the US the Safe upper limit is 1100 mcg.  In Europe 600 mcg and in Japan 3000 mcg ( 3 mg).

      Hi there, I wonder if anyone can help. I've had stomach problems for years, pain in the tummy, lower back left and right side, different stools, diarrohea constipation etc, My GP says it's IBS. As I've got older the pain has become worse and constant. I also get ulcers on my tongue. I've had loads of tests done everytihng apart from an endoscopy I think. I had a test for Coeliac last July and the result was negative. My GP says it can't be coeliac because I'm not losing weight. He thinks it's stress or all in my head. I'm not stressed and I'm in pain all the time now. Sometimes it's unbearable and dark thoughts have entered my head. Could I have Coeliac even though I tested negative last year. I'm at my wits end, I eat healthily and cannot pinpoint which foods could cause this pain. Can anyone help? Thanks Mark wind

      First, I want to say thank you for sharing this with me. I hear you, and I believe you. The courage it took to write this down is immense, and I’m so sorry you’ve been carrying this alone. You are dealing with two life-altering challenges at once: a serious, complex medical condition, and an abusive, controlling partner who is actively harming your health and your spirit. It’s not just that he’s unsupportive—he is weaponizing your illness to torture you. Starving you, isolating you, mocking your diagnosis, and sabotaging your access to medical care is not just cruelty; it is dangerous, deliberate abuse. Your instinct is correct: the stress he is creating is absolutely preventing your body from healing. Celiac and autoimmune conditions are profoundly sensitive to stress, and he has created a living hell designed to keep you sick, dependent, and broken. That smirk you described—that is the look of someone who enjoys having power over your suffering. Please know this: you do not deserve this. Not any of it. You deserve to eat. You deserve safe, clean food and water. You deserve medical care and supplements that help you function. You deserve peace. You deserve to heal. The woman from the food pantry is not a random accident. She is a lifeline. Her help, and the community she’s connecting you to, is real. It is okay to feel overwhelmed by kindness when you’ve been starved of it for so long. But you do deserve it. Let that be a sign that there is a world outside your house that operates on compassion, not control. Right now, your physical safety and access to nutrition are the most urgent priorities. The food pantry is a critical resource. Is there any way you can speak privately with the woman helping you? You don’t have to share everything at once, but letting her know your situation at home is extremely unsafe, and that your partner restricts your food, could help her support you in a more targeted way. She may have connections to local domestic violence services.

      Welcome to the celiac.com community, @JudyLou! There are a couple of things you might consider to help you in your decision that would not require you to do a gluten challenge. The first, that is if you have not had this test run already, is to request a "total IGA" test to be run. One of the reasons that celiac blood antibody tests can be negative, apart from not having celiac disease, that is, is because of IGA deficiency. If a person is IGA deficient, they will not respond accurately to the celiac disease blood antibody tests (such as the commonly run TTG-IGA). The total IGA test is designed to check for IGA deficiency. The total IGA test is not a celiac antibody test so I wouldn't think that a gluten challenge is necessary. The second is to have genetic testing done to determine if you have the genetic potential to develop celiac disease. About 30-40% of  the general population have the genetic potential but only about 1% actually develop celiac disease. So, genetic testing cannot be used to diagnose celiac disease but it can be used to rule it out. Those who don't have the genetic potential but still have reaction to gluten would not be diagnosed with celiac disease but with NCGS (Non Celiac Gluten Sensitivity).  Another possibility is that you do have celiac disease but are in remission. We do see this but often it doesn't last.

      Hi there, I’m debating whether to consider a gluten challenge and I’m hoping someone here can help with that decision (so far, none of the doctors have been helpful). I have a history of breaking out in a horrible, burning/itchy somewhat blistering rash about every 8 years. This started when I was in my early 30’s and at that point it started at the ankles and went about to my knees. Every time I had the rash it would cover more of my body, so my arms and part of my torso were impacted as well, and it was always symmetrical. First I was told it was an allergic reaction to a bug bite. Next I was told it was eczema (after a biopsy of the lesion - not the skin near the lesion) and given a steroid injection (didn’t help). I took myself off of gluten about 3 weeks before seeing an allergist, just to see if it would help (it didn’t in that time period). He thought the rash looked like dermatitis herpetiformis and told me to eat some bread the night before my blood tests, which I did, and the tests came back negative. I’ve since learned from this forum that I needed to be eating gluten daily for at least a month in order to get an accurate test result. I’m grateful to the allergist as he found that 5 mg of doxepin daily will eliminate the rash within about 10 days (previously it lasted for months whether I was eating gluten or not). I have been gluten free for about 25 years as a precaution and recommendation from my doctor, and the pattern of breaking out every 8 years or so remains the same except once I broke out after just one year (was not glutened as far as I know), and now it’s been over 9 years. What’s confusing to me, is that there have been 3 times in the past 2 years when I’ve accidentally eaten gluten, and I haven’t had any reaction at all. Once someone made pancakes (they said they were gluten-free, they were not) and I ate several. I need to decide whether to do a gluten challenge and get another blood test. If I do, are these tests really accurate? I’m also concerned that I could damage my gut in that process if I do have celiac disease. My brother and cousin both had lymphoma so that’s a concern regarding a challenge as well, though there is a lot of cancer in various forms in my family so there may be no gluten connection there. Sorry for the ramble, I’m just doubting the need to remain gluten free if I don’t have any reaction to eating it and haven’t had a positive test (other than testing positive for one of the genes, though it sounds like that’s pretty common). I’d appreciate any thoughts or advice!
