Are potatoes gluten-free?
Potatoes in their raw form do not contain any gluten.

Raw potatoes are gluten-free and suitable for people with celiac disease (an autoimmune digestive disease that affects the small intestine's ability to absorb nutrients from the food), gluten-intolerant people, and individuals with special dietary needs.

Potatoes are versatile starchy vegetables that are gluten-free in all their varieties and can be eaten in many ways, ranging from simply mashing boiled or roasted potatoes with added flavors to French fries, salads, baked potatoes, and casseroles.

Potatoes with intact skin are low-calorie, complex carbohydrates with a solid dose of fiber and vitamin C.

Can potatoes become contaminated with gluten?

You need to be cautious in case of cross-contact or if any additional ingredients are used that may contain gluten, which may make potatoes no longer safe for people with celiac disease. This can occur when:

  • In a restaurant, potatoes are boiled in water that once boiled gluten-rich food such as pasta.
  • A gluten-containing sauce was added to the potato recipe.
  • Same pots, pans, knives, and cooking surfaces are used without thorough cleaning.
  • Porous surfaces such as wooden utensils or cutting boards can have gluten trapped in the cracks.

What is a gluten-free diet?

A gluten-free diet excludes all products that contain gluten.

This diet is currently the only treatment for people with celiac disease and those living with non-celiac gluten sensitivity.

Gluten is a type of protein found in wheat, rye, barley, and other grains that plays several roles in foods, such as providing structure, texture, protein, and flavor.

Who should avoid gluten?

People with celiac disease, those who are gluten-intolerant, those with restricted diets, and those who are looking to reduce the amount of gluten consumption in their diet because of their personal choice are the ones who want their diets to be gluten-restricted.

It is not as if gluten is a bad thing for people without intolerance; it is a part of the nutritional package of healthy foods such as whole grains. Instead, try dropping refined foods that have gluten in them (often used to bulk them out or make them taste better) as it will help better.

What is gluten intolerance?

Gluten intolerance, sometimes referred to as non-celiac gluten sensitivity, is a set of uncomfortable symptoms that a person experiences after consuming gluten.

The severe form of gluten intolerance is an autoimmune condition called celiac disease that is estimated to affect approximately one percent of the population and about 1 in every 141 Americans although many cases remain undiagnosed.

Common symptoms of gluten intolerance may include:

How is gluten intolerance diagnosed?

There are no specific laboratory tests or biomarkers to formally diagnose gluten intolerance or non-celiac gluten sensitivity. It can only be subjectively diagnosed by self-reported information.

  • Blood and/or skin prick tests or an upper endoscopy procedure (if needed): To rule out a wheat allergy and celiac disease
  • Following an elimination diet: The healthcare provider assesses symptoms after removing gluten from your diet for a while and then reintroduces gluten to monitor your reaction
