Why do i always get nauseated when i eat eggs ?

Gastric emptying?: Dietary fats (of which eggs are high in cholesterol) takes longer to empty from the stomach than proteins and carbohydrates (e.g. What you find in vegan diets). Your nausea may reflect this when eating fatty foods. Nausea is however a surprisingly multifactorial symptom that warrants medical evaluation if persistent after dietary modification. May also just be a food intolerance unique to you.
