It Depends

Most mayonnaise is naturally gluten-free and safe for celiac disease. Learn which brands are verified safe, what to watch for in flavored varieties, and how to avoid hidden gluten in mayo-based foods.

The short answer: Most plain mayonnaise is naturally gluten-free and safe for celiac disease. Traditional mayo is made from eggs, oil, vinegar or lemon juice, and seasonings — all naturally gluten-free ingredients. However, some flavored varieties and mayo-based products may contain gluten, so label reading is essential.

Why Plain Mayo Is Safe

Traditional mayonnaise ingredients:

  • Eggs/egg yolks — Naturally gluten-free
  • Oil (vegetable, canola, olive) — Naturally gluten-free
  • Vinegar (distilled white, cider) — Gluten-free
  • Lemon juice — Naturally gluten-free
  • Salt — Naturally gluten-free
  • Sugar — Naturally gluten-free
  • Mustard — Usually gluten-free

No wheat, barley, or rye is required to make mayonnaise. The basic recipe has been naturally gluten-free since its invention.

Restaurant Mayo Concerns

At restaurants, mayo itself is usually safe, but watch for:

Deli Counter Risks

Deli-prepared mayo salads have cross-contact risks:

  • Shared scoops with wheat-containing items

For strictest safety: Make mayo-based salads at home with verified GF ingredients.
