Biological Proof: Why Eggs Can Never Be Dairy Under Any Nutritional Standard
By Maya Lin-Takahashi
Q1: Why do eggs sit in the dairy cooler at the grocery store?
A1: Supermarkets place them together purely for refrigeration logistics. In the mid-twentieth century, distribution routes and retail designs clustered temperature-sensitive goods along shared refrigerated walls near delivery docks. This floor plan was chosen for cold-chain efficiency, not nutritional science.
Q2: Can someone with lactose intolerance safely eat eggs?
A2: Yes. Eggs do not contain lactose. Lactose is a disaccharide sugar found exclusively in the milk of mammals. Eggs come from birds and contain only trace amounts of free glucose, making them safe for anyone managing lactase deficiency.
Q3: If a food package says "Dairy-Free," can it contain eggs?
A3: Yes. Under FDA food labeling guidelines, the claim "dairy-free" means the product contains no ingredients derived from mammalian milk. Because eggs are classified as poultry protein, a product labeled dairy-free may still contain eggs, though common allergens must still be disclosed on the ingredient panel.
