What’s an individual to do once they’ve eradicated all the large allergens—gluten, dairy, eggs, nuts—they usually’re nonetheless having mysterious signs that appear to be aggravated by their food regimen? Perhaps you’re that particular person. You’ve tried Primal, AIP, and low-FODMAP diets, however you continue to have recurring points together with your intestine, pores and skin, or power ranges. Or, you regularly expertise nausea or GI misery after meals even after eliminating the obvious potential triggers.

When it’s not one of many large gamers providing you with grief, assume smaller. Typically these gadgets farther down the ingredient record are the true culprits. I’m speaking in regards to the issues that meals producers add to their merchandise to enhance texture, look, and shelf stability. They’re thought of secure for consumption (within the U.S., although not essentially in different nations, as you’ll see), however these sneaky little buggers may be making you unwell nonetheless.

Listed below are some issues to look out for in case you’re having persistent well being points that you just suspect are tied to one thing you’re consuming.

Purple Dye and Different Synthetic Meals Coloring

Granted, Primal eaters in all probability aren’t consuming giant portions of meals loaded with synthetic coloring brokers. Nonetheless, they’re pervasive within the American meals provide. You’ll additionally discover them in drugs and dietary supplements, typically at alarmingly excessive ranges. Even at high-end grocers and well being meals shops, they’re exhausting to keep away from.

The U.S. Meals and Drug Administration (FDA) at present permits Blue 1, Blue 2, Inexperienced 3, Yellow 5, Yellow 6, Purple 3, Purple 40, Citrus Purple 2, and Orange B in meals at authorised ranges. Nonetheless, scientists and public well being officers have identified for many years that every of those carries potential well being dangers, particularly the purple and yellow dyes. The FDA banned Purple 3 (aka erythrosine or E127) in cosmetics and different topical functions in 1990 based mostly on research displaying elevated thyroid most cancers danger, however it’s nonetheless authorised as a meals colorant. Yellow 6 (aka tartrazine or E110) and Purple 40 (aka Allura Purple AC or E129) require warning labels or are banned altogether in a number of nations because of considerations about their doable carcinogenic results and their results on kids. In addition they occur to be probably the most prevalent synthetic meals colorings within the U.S.

The primary time I heard about meals dyes affecting children was years in the past when a buddy advised me she couldn’t give her daughter any meals or juice that had purple dye in it. As she described it, only a few items of sweet or a bit of sheet cake with brightly coloured frosting at a party, and her usually candy child could be bouncing off the partitions. It seems that’s not so unusual. A number of research have concluded that meals dyes might contribute to hyperactivity and different behavioral issues, particularly in children with preexisting ADHD signs. The FDA reviewed the scientific proof ten years in the past and determined it wasn’t conclusive sufficient to behave on. A 2018 evaluation printed in Pediatrics, the official publication of the American Academy of Pediatrics, renewed the decision for extra analysis and for the FDA to rethink its security requirements relating to synthetic meals dyes. Nothing has modified since then.

Along with these considerations, some people are delicate or allergic to meals dyes. Signs embody respiration points, complications, or, in excessive instances, anaphylaxis.

All that is to say, synthetic meals dyes are extremely suspect. The irritating factor is, we now have pure alternate options, however most meals producers don’t use them except they’re pressured to.



Carrageenan is a meals thickener and stabilizer derived from purple algae. You’ll generally discover it in dairy merchandise, soups, sauces, and non-dairy milk substitutes like almond milk and coconut milk. As with all of the components mentioned right this moment, it’s FDA authorised. Nonetheless, carrageenan has seen its justifiable share of controversy.

In 2016, the Nationwide Natural Requirements Board voted to take away carrageenan from its record of authorised substances, citing questionable manufacturing practices. That will have meant that merchandise containing carrageenan might not be designated as natural within the U.S.—besides the USDA, which in the end governs natural certification, did not undertake their suggestion.

Meals security advocates additionally elevate considerations about carrageenan’s pro-inflammatory properties. A associated product known as degraded carrageenan, or poligeenan, is a well known inflammatory agent and doable carcinogen. In truth, it’s utilized in pharmaceutical research particularly to induce irritation. There’s loads of proof that degraded carrageenan causes all types of issues in animal research. That isn’t alarming in and of itself since degraded carrageenan is chemically distinct from the carrageenan in your meals. Nonetheless, some security advocates argue that food-grade carrageenan can turn into degraded by abdomen acid.

It’s not clear how a lot that truly occurs. Morever, no human research instantly check carrageenan’s security, and animal research have yielded inconsistent findings. That leaves us with largely anecdotal proof to go on. Anecdotally, some individuals with digestive points like bloating or gasoline expertise reduction once they remove carrageenan. This tracks with animal research displaying the principle hostile impact of carrageenan is diarrhea.

People with alpha-gal syndrome, a uncommon allergy to meals from mammals, may react strongly to carrageenan because it accommodates alpha-gal epitopes. For some, carrageenan is an even bigger set off than meat or dairy merchandise.

Soy Lecithin

I do know some Primal people will see the phrase soy and routinely reject soy lecithin, however maintain up. Sure, soy lecithin is derived from soybeans, nevertheless it’s fairly totally different from typical soy-based meals.

Soy lecithin is the top product of soybean oil manufacturing. The refining course of itself consists of some troubling steps, together with using hexane to extract the soybean oil. Nonetheless, there’s no actual proof that harmful ranges of any hazardous byproducts stay in food-grade soy lecithin. It additionally lacks the soy proteins that set off soy allergy symptoms, so most individuals don’t have any issues with lecithin even when they should keep away from different soy merchandise.

Chris Kresser has carried out a reasonably thorough write-up of soy lecithin’s professionals and cons. Total, I’m pretty convinced that soy lecithin is benign for most individuals in small quantities. Presumably, although, my love of dark chocolate is swaying my verdict. It’s fairly exhausting to seek out darkish chocolate with out soy lecithin on the ingredient record. (Hu and Alter Eco are two manufacturers price making an attempt.)

I’m protecting soy lecithin on the record as a result of anecdotally, some individuals nonetheless appear to react to it poorly. People with critical soy allergy symptoms ought to keep away from it till they test with their docs.

Guar Gum and Xanthan Gum

I’m lumping these two collectively as a result of they’re functionally related. Each are used as meals thickening brokers. In truth, I beforehand recommended them as worthy low-carb choices for thickening sauces, stews, and soups.

Guar gum is derived from the guar bean, whereas xanthan gum is created by means of bacterial fermentation. Each comprise excessive ranges of soluble fiber. Analysis means that they might confer among the similar well being advantages related to fiber usually, resembling performing as a prebiotic, decreasing LDL, bettering glycemic management, and treating constipation. As we all know, although, more fiber isn’t all the time higher. For people with IBD, for instance, fiber can really be counterproductive, exacerbating GI points.

It’s no shock, then, that each guar gum and xanthan gum can have undesirable laxative results. Though human analysis is missing, some individuals expertise gasoline, cramping, and diarrhea once they eat meals with these gums. I’d be conscious of this risk if I used to be battling Crohn’s, colitis, IBD, or the like.

Monosodium Glutamate (MSG)

I’m undecided what number of of you might be sufficiently old to recollect, however there was a time thirty years in the past or so the place MSG was the ingredient everybody beloved to hate. The favored media blamed MSG for numerous well being issues. Chinese language meals eating places rushed to distance themselves from MSG. As often occurs, the fervor subsided, though you may nonetheless have a nagging sense that you need to keep away from MSG.

Within the meantime, research did not substantiate that MSG is correlated with any main well being issues when consumed in small portions. Nonetheless, some proportion of the inhabitants is outwardly delicate to MSG. These individuals report signs resembling nausea, flushing, speedy heartbeat, diarrhea, and complications once they eat meals made with MSG.

A part in MSG known as free glutamate might be answerable for these reactions. That is necessary as a result of free glutamate can also be present in meals that don’t comprise MSG. Carrageenan is a possible supply of free glutamate, as is soy sauce. One other that Primal eaters may be consuming is dietary yeast, the cheese substitute that provides an interesting umami taste to vegan sauces and vegetable dishes.

I don’t exit of my strategy to keep away from MSG or free glutamate, however I additionally don’t eat plenty of restaurant meals probably containing MSG. Nonetheless, I would be taking a more in-depth have a look at ingredient labels if I used to be experiencing any of the aforementioned signs.

Ought to Everybody Be Avoiding These Components as a Matter of Course?

It’s a legitimate query, however I believe the reply is no, aside from the meals dyes. The security information for synthetic meals dyes are troubling sufficient that I like to recommend avoiding them as a lot as doable. As for the remaining, in case you’re consuming a Primal food regimen, your publicity to those substances might be fairly minimal to start with. Should you’re not having any apparent points with them, I see no compelling purpose to keep away from them fully. Alternatively, they don’t add something to your food regimen, nutritionally talking. Should you select to keep away from them on precept, you’re actually not lacking out.

This publish isn’t meant to be a diatribe in regards to the risks of processed meals. Realistically, most individuals eat some ready, pre-packaged meals for causes of comfort, price, or just to deal with themselves. If you wish to sometimes nosh some sweet on the films, otherwise you decide up snacks on the gasoline station on a highway journey, you gained’t discover me chastising you. Heck, I’m the man who got here up with the 80/20 rule within the first place.

Whereas it’s nice to “clear up” your food regimen and setting, do not forget that the hunt for optimum well being shouldn’t be inflicting you stress and anxiousness. It ought to really feel liberating, not oppressive. Within the hierarchy of issues to fret about, these components are low on the record except you’re having undesirable signs which can be interfering together with your high quality of life. If that’s the case, then it’s completely price taking a more in-depth have a look at ingredient labels.

As for the remainder of us? Maintain specializing in consuming largely Primal meals, and also you’ll be effective.

Plus, as increasingly meals producers cater to picky customers who need fewer components of their meals, it should turn into simpler to seek out great-tasting choices in your native grocery store. Primal Kitchen already bans these substances in all our merchandise. I count on extra firms to observe go well with as client demand will increase, so sustain the stress!

Inform me: Have you ever had any success eliminating pesky signs by slicing out one among these supposedly innocent substances?
