Mostly false Certainty of evidence: low provisional C-EGG-01

Eating eggs causes snoring, sinusitis and nightmares in (practically) everyone who eats them, and stopping eggs and chicken relieves headaches.

Safety note: Chronic sinus symptoms, loud snoring with breathing pauses (possible sleep apnoea) and recurrent headaches can have treatable medical causes; they should be evaluated by a doctor rather than attributed to eggs alone.
Conclusion: Eggs can cause symptoms in people with egg allergy, but there is no evidence that eggs cause snoring, sinusitis or nightmares in general.

Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: low – Further research is likely to change the assessment considerably.

1. What was claimed?

Elawady states in a live video that nobody eats eggs without snoring, sinus problems or nightmares, and that stopping eggs makes sinus problems disappear; the archive adds that stopping eggs and chicken eases headaches.

2. What is demonstrably correct?

A small minority of people have egg allergy, which can include nasal symptoms. Some people report that certain foods worsen their sleep or dreams; in a 2025 survey food allergy and lactose intolerance were associated with nightmare scores. An individual who reacts to eggs can feel better after avoiding them.

3. What is wrong or exaggerated?

The statement is generalised to everyone who eats eggs. Confirmed egg allergy in Europe affects under 1% of the population in pooled challenge-verified data. In two dream surveys, the foods most often blamed for disturbing dreams were dairy and sweets, not eggs. No study links normal egg consumption to snoring or chronic sinusitis in the general population.

4. What remains unclear?

Whether non-allergic food sensitivities to eggs cause sleep or headache symptoms in a subgroup has not been studied well. Anecdotal improvements after a large diet change cannot be attributed to one food.

5. Which studies support it?

Only indirect: egg allergy exists (I-EGG-11). Food allergy and intolerance are associated with nightmare reports in a self-report survey (I-EGG-13), but in that survey eggs were named in only 3 of 131 food choices and in none for disturbing or bizarre dreams.

6. Which studies contradict it?

Low prevalence of egg allergy (I-EGG-11); eggs not among the foods blamed for disturbing dreams (I-EGG-12: eggs not mentioned; I-EGG-13: 3 of 131 food choices, none for disturbing dreams). Neither survey measured snoring, sinusitis or headache, so this evidence is very indirect. No study supporting a general effect was found.

7. What applies to Germany and Europe?

Egg allergy is a recognised food allergy; in the EU, egg is one of the allergens that must be declared on food labels. Allergy diagnosis is done by allergists (history, skin/IgE tests, oral food challenge).

8. What is known about Egypt?

No Egyptian data on egg allergy prevalence were reviewed. The claim does not depend on local production.

9. What practical conclusion is appropriate?

People who suspect that eggs cause symptoms should have this checked (e.g., allergy testing or a supervised elimination and re-challenge). There is no evidence that everyone should stop eggs to prevent snoring, sinusitis, nightmares or headaches.

Assessment details

Rationale for certainty of evidence

No study was found that tested eggs as a cause of snoring, sinusitis or nightmares in the general population; the verdict rests on indirect evidence (prevalence of egg allergy, food-and-dream surveys) and on the universal wording ('nobody who eats eggs ...'), which is contradicted by everyday observation. Absence of direct trials lowers certainty.

Source quality

Own words in machine transcripts (several videos, consistent message) plus an archive paraphrase; supported only by anecdotes from callers.

Regional transferability

The claim is universal; nothing in it depends on region or production system.

Individual exceptions

Egg allergy is real: in Europe the pooled point prevalence of food-challenge-verified egg allergy is 0.8% (95% CI 0.5-1.2), mostly in children. In allergic people eggs can cause nasal and other symptoms. Food intolerances can also be associated with poor sleep and nightmares in surveys.

Regional scope of the claim
not specified
Last reviewed
25 October 2026 provisional

In plain language

Dr. Elawady said that everyone who eats eggs snores, has sinus problems or has nightmares. Research does not support this. True egg allergy exists, but in Europe it affects fewer than 1 in 100 people in tested studies, mostly children. In surveys about food and dreams, people most often blamed dairy products and sweets, not eggs. If you notice symptoms after eating eggs, an allergy test can clarify whether eggs are the cause.

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    How common is perceived food-dependent dreaming, and which foods are blamed?

    How was the study done?

    Questionnaire survey of students

    How many people, animals or samples were studied?

    396 students; Students

    What was actually found?

    17.8% (68/382) thought food or late eating affected their dreams. Among the few who named foods (32 and 26 people), dairy was blamed most (44% for disturbing, 39% for bizarre dreams); sweets, spicy and starchy foods and meat followed; eggs and chicken were not mentioned.
