Healing Migraines Naturally: What You Need to Know About Hidden Triggers in Your Diet
Migraines are more than just headaches — they can steal your energy, focus, and joy from everyday life. For many people, migraines come with nausea, light sensitivity, and a feeling of being “out of commission” for days.
But what if the root cause of your migraines isn’t just stress or hormones? What if it’s something as simple ~ and fixable ~ as what’s hiding in your food?
That’s exactly what Dr. Elizabeth Yarnell, ND, a naturopathic doctor and expert in food sensitivity and inflammation, shared in her interview with Dr. Amelia Scott Barrett, MD. In this conversation, Dr. Yarnell explained how common ingredients found in our everyday diets can quietly trigger inflammation ~ and with it, debilitating migraines. Dr. Barrett developed with world’s first DNA test kit specifically for people with chronic headaches or migraine, and it tells you exactly which foods might be a problem for you.

This post will break down Dr. Yarnell’s top recommendations for what to remove from your diet, how to identify your personal migraine triggers, and simple steps you can take starting today to find relief naturally.
The Hidden Link Between Food and Migraines
Many migraine sufferers already know that certain foods — like chocolate, caffeine, or red wine — can be triggers. But Dr. Yarnell takes it deeper: it’s not just specific foods, it’s the chemical compounds inside them and how your unique body reacts.
“I’ve even tested twins,” said Dr. Yarnell, “and their profiles for food sensitivities are radically different.”
This means there’s no one-size-fits-all diet for migraine prevention. However, there are three common offenders that most people with migraines should avoid. These ingredients sneak into foods you might think are harmless — and they could be silently fueling inflammation every day.
1. Artificial Sweeteners: The Hidden Chemical in Your “Healthy” Choices
When asked what the first ingredient to eliminate should be, Dr. Yarnell didn’t hesitate:
“Number one is artificial sweeteners. High fructose corn syrup, saccharin, Splenda, Equal — really any of those artificially created sugar substitutes.”
Artificial sweeteners are marketed as “healthier” alternatives to sugar, but your body doesn’t recognize them as food. Instead, they’re treated like foreign chemicals.
“Your stomach says, ‘Oh, let me identify this food the way it would any other food,’” she explained. “And it can’t, because it’s chemical-based. We did not evolve to eat these artificial ingredients — many of which come from petroleum products.”
Yes, petroleum — the same substance used to make fuel.
Why Artificial Sweeteners Trigger Migraines
Your body is remarkably sensitive to substances it can’t metabolize properly. When artificial sweeteners enter your system, they can disrupt your gut bacteria, trigger inflammatory reactions, and confuse your hunger and fullness signals. For someone already prone to migraines, these chemical disruptions can spark neurological inflammation — one of the key factors behind migraine onset.
Actionable Takeaway
Start by cutting out:
-
Diet sodas (even “zero-calorie” or “sugar-free” versions)
-
Protein shakes, yogurts, and bars labeled with sucralose, aspartame, or “no sugar added”
-
Processed snacks using “high fructose corn syrup”
Instead, use natural sweeteners like pure maple syrup, raw honey, or coconut sugar in moderation.
If you crave fizz, swap soda for sparkling water with real fruit — not “natural flavors” (we’ll get to that later).
2. Artificial Colors: The Brightly Colored Culprit You Don’t Suspect
Dr. Yarnell’s second migraine-triggering food additive might surprise you: artificial colors.
“Artificial colors are often labeled as FD&C followed by a number,” she said. “Before the 1930s, food colorings were sourced from coal. Then they realized it was cheaper to source them from petroleum.”
In other words — those pretty red, blue, and yellow hues in your favorite snacks and drinks? They’re derived from petroleum, not plants.
Why Artificial Colors Are Dangerous for Migraine Sufferers
These chemical dyes can trigger immune and inflammatory responses — especially in people who are already sensitive or have autoimmune conditions.
“We did not evolve on this planet to process something that comes from two miles underneath the Earth,” Dr. Yarnell said.
And the reaction doesn’t have to be large. Even a trace amount can trigger symptoms in sensitive individuals.
“For my son, he’s very sensitive to red food dye,” she shared. “Even the red ‘T’ on a little capsule of Tylenol is enough to set him off — into a migraine, then progressing into vomiting.”
Actionable Takeaway
Avoid foods with:
-
FD&C Red 40, Yellow 5, Blue 1
-
Caramel color (often in soft drinks and sauces)
-
Brightly colored candies, cereals, or beverages
You can find natural alternatives made from beets, turmeric, or saffron. If you love baking, try using plant-based dyes available in health food stores.
Also, read your medication labels — many over-the-counter drugs and vitamins contain unnecessary dyes. Look for “dye-free” versions instead.
“There’s nothing medicinal in the red dye on the Tylenol,” Dr. Yarnell emphasized.
3. “Natural Flavors”: The Sneaky Ingredient That Isn’t Natural at All
If you’ve made the switch to “healthier” foods and beverages, you might feel confident seeing natural flavors on the label. But according to Dr. Yarnell, that confidence is misplaced.
“The number three thing to take out of your diet is ‘natural flavors,’” she warned. “Natural flavors is an FDA-approved catch-all that allows companies to create a flavor that may have one molecule from nature — but then 30 or more chemicals added to it.”
These so-called “natural” flavors are designed by massive multinational corporations that also produce fragrances for cleaning products and perfumes.
“All these things — from the flavor in McDonald’s milkshakes to the scent of Pine-Sol — come from the same companies,” she said. “And they do not have to disclose what’s in them.”
Why “Natural Flavors” Can Trigger Inflammation
For someone with inflammation-based health issues — like migraines, autoimmune diseases, or chronic fatigue — these chemical cocktails can easily provoke reactions.
Dr. Yarnell, who lives with multiple sclerosis, has experienced this firsthand:
“When I have a sip of those flavored carbonated waters — with ‘natural flavors’ — my eyelids start to itch. Then they peel. If I continue, they eventually start to bleed.”
That’s a dramatic example of what hidden additives can do to a sensitive body.
Actionable Takeaway
Avoid any ingredient label that includes:
-
Natural flavors
-
Flavor, fragrance, aroma, or parfum
Instead, choose foods that list real ingredients, like mint, rosemary, lemon, or vanilla extract.
And don’t be fooled by flavored sparkling waters or energy drinks labeled as “clean.” Even “zero sugar” versions may contain chemical flavor compounds.
How to Identify Your Unique Migraine Triggers
Dr. Yarnell emphasizes that food sensitivities are personal. What causes migraines in one person might not affect another at all. That’s why identifying your specific triggers is crucial.
1. Try an Elimination Diet
Remove the three big triggers above — artificial sweeteners, colors, and flavors — for three weeks. Track how your migraines respond.
Keep a migraine diary that notes what you eat, how you feel, and any symptoms. If you experience fewer headaches, you’ve already uncovered part of your solution.
Then, gradually reintroduce one item at a time to see if symptoms return.
2. Consider Food Sensitivity Testing
Dr. Yarnell recommends testing like the MRT (Mediator Release Test) to identify specific inflammatory triggers in your diet.
“Sometimes even the smallest amount can trigger an inflammatory response,” she explained.
This test can reveal hidden sensitivities — including to additives in medications or supplements — so you can eliminate them systematically.
3. Read Labels Like a Detective
Food marketing is designed to trick you. “Natural,” “light,” “zero sugar,” or “low-fat” doesn’t mean healthy.
Instead, focus on short ingredient lists with recognizable items — and avoid anything that sounds like a chemistry experiment.
If you can’t pronounce it or find it in nature, your body probably won’t like it either.
Building a Migraine-Friendly Kitchen
A migraine-safe kitchen doesn’t have to be complicated. Here’s how to stock yours:
Pantry Staples:
-
Organic whole grains (quinoa, brown rice, oats)
-
Raw nuts and seeds
-
Herbs and spices (turmeric, ginger, rosemary)
-
Raw honey or pure maple syrup
Fridge & Freezer:
-
Fresh vegetables and fruits (especially leafy greens, berries, cucumbers)
-
Wild-caught fish (rich in omega-3s)
-
Grass-fed meats or plant-based proteins
-
Non-dairy milk alternatives without “natural flavors”
When shopping, take a few extra seconds to read the label. That habit alone could spare you countless migraine days.
The Bigger Picture: Empowering Yourself Through Awareness
Migraines can make you feel powerless — especially when medication only masks the pain. But Dr. Yarnell’s insights show that you have more control than you think.
“Sometimes even the smallest amount of a trigger can set off inflammation,” she said, “but once you understand what your body is sensitive to, you can live a great life. I can dance the night away — as long as I don’t have natural flavors or something like that.”
The power lies in knowledge — and in small, consistent choices.
You don’t have to overhaul your entire diet overnight. Start by eliminating one of the three triggers, and notice how your body responds.
Healing migraines from the inside out takes patience, but every step toward reducing inflammation brings you closer to a pain-free life.
Final Takeaway: The “Clean Food” Migraine Challenge
If you’re tired of unpredictable headaches, challenge yourself to 21 days of clean eating:
-
No artificial sweeteners
-
No artificial colors
-
No “natural flavors”
Keep track of your symptoms and energy. Most patients start noticing improvement within 1–2 weeks.
Migraines may feel mysterious, but as Dr. Yarnell reminds us, your body is speaking — inflammation is its language. Once you remove the noise from your diet, you’ll finally be able to hear what it’s been saying all along.
