Salty fries, a cold Coke, and your migraine disappears? This combination, called “McMigraine,” is taking social media by storm… but doctors are urging caution.

Where did this strange idea come from?

In recent weeks, many videos on TikTok have been promoting a supposed miracle cure for migraines: ordering a savory and sweet dish at a fast food restaurant. A caffeinated cola and plenty of fries = guaranteed relief, claim some migraine sufferers.

This viral trend has been dubbed “McMigraine,” a reference to a well-known fast food chain. And it’s not just a few anecdotal reports: millions of views, enthusiastic comments, and even the intervention of an American neurologist, captured in a viral video, underscore this “trend.”

What science says about caffeine and migraines

There is some truth to it. Caffeine—found in both cola and coffee—can relieve some migraines. It works by slightly constricting dilated blood vessels in the brain, which can alleviate pain. That is why it is found in some painkillers available in pharmacies.

But be careful: this effect varies significantly from person to person. In some people, caffeine can trigger an attack. Dr. Kennis, a neurologist quoted by the BBC, points out that “excessive caffeine consumption is a known factor in the onset of migraines in some patients.”

And what about the salt on the fries?

The other argument put forward by “McMigraine” fans is that salty fries relieve migraines. Why? Salt helps to restore electrolyte balance, especially sodium balance, which can sometimes be depleted in people who have not eaten or drunk enough.

This is also true—with some nuances. In some cases, such as prolonged fasting or mild dehydration, eating salty foods can relieve some migraine symptoms (fatigue, dizziness). However, this does not solve the underlying problem. And above all, excessive salt consumption—as is often the case in fast food restaurants—can exacerbate other health problems or even trigger headaches in some people.

What neurologists say

Doctors agree: no food cures migraines, but certain dietary factors can help prevent or alleviate attacks. In an interview with Doctissimo, neurologist Wilfrid Casseron emphasizes that every migraine patient is unique: “Some people should avoid fasting, others should limit fatty meals or even chocolate…”

What works for one person may worsen symptoms in another. He adds that the best strategy is based on personal knowledge of triggers: stress, bright light, lack of sleep, certain smells, or foods. This is a fundamental approach, far removed from the “quick fixes” that go viral on social media.

McMigraine: A false friend?

Apart from its questionable effectiveness, the “McMigraine menu” can prove counterproductive in the long run. Highly processed foods, often found in fast food restaurants, contain additives, saturated fats, and sometimes substances such as tyramine, which can trigger migraines in some people.

In addition, in cases of chronic migraine, unsupervised dietary self-medication can delay appropriate medical care. Experts therefore recommend consulting a doctor to ensure individualized care and, if necessary, receive proper treatment.

The “McMigraine” menu elicits smiles and curiosity and fuels a current trend: the search for quick fixes. However, when it comes to migraines, dietary shortcuts are no substitute for caution or medical expertise. The key? Listen to your body, understand its reactions…and let TikTok do what it does best: entertain, not diagnose.
