Are Potatoes Gluten Free? 🥔✅
Yes, plain potatoes are 100% naturally gluten free. Gluten is a protein found in wheat, barley, and rye—not in vegetables. This means fresh-cut potatoes used to make French fries start off safe for a gluten-free diet.
However, gluten can be introduced during processing, seasoning, or cooking, especially in restaurants or when using pre-packaged frozen fries.
Common Sources of Gluten in French Fries ⚠️
French fries may become unsafe due to:
👉 Shared Fryers: Restaurants often use the
same fryer for breaded foods like nuggets, which leads to
cross-contact.
👉
Seasonings or Coatings: Some frozen or
restaurant fries are dusted with wheat flour for crispiness
or flavored with gluten-containing ingredients.
👉
Additives in Frozen Fries: Brands may use
modified food starch, malt extract, or other ingredients
derived from gluten grains. Always check the label.
