Can celiac have olive oil?

Quick Answer

Yes, people with celiac disease can safely consume olive oil. Olive oil is made by pressing olives and extracting the oil, which does not contain any gluten. As long as the olive oil is pure and uncontaminated, it is considered gluten-free and safe for people with celiac disease or gluten sensitivity.

What is Celiac Disease?

Celiac disease is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. Gluten is a protein found in grains like wheat, barley and rye. In people with celiac disease, gluten triggers an immune response that attacks the small intestine, leading to damage and inability to absorb nutrients properly. Symptoms of celiac disease include diarrhea, abdominal pain, bloating, weight loss, fatigue and anemia. The only treatment for celiac disease is maintaining a strict lifelong gluten-free diet, which allows the intestinal lining to heal.

What Foods Contain Gluten?

Gluten is primarily found in foods made from wheat, barley and rye. This includes bread, pasta, baked goods, cereals, beer and some processed foods. Oats are naturally gluten-free but are often cross-contaminated with gluten during processing. People with celiac disease need to avoid all foods and products made with gluten-containing grains.

Here are some examples of foods that contain gluten:

  • Bread, pasta, crackers, baked goods
  • Wheat, barley, rye, spelt, triticale
  • Malt vinegar, beers, ales
  • Soy sauce, teriyaki sauce
  • Croutons, stuffing, coating mixes
  • Cereals, granola bars, cookies, cakes

What Foods are Gluten-Free?

Many healthy and nutritious foods are naturally gluten-free, including:

  • Fruits, vegetables, legumes, nuts, seeds
  • Meats, fish, poultry, eggs
  • Milk, yogurt, cheese
  • Rice, corn, quinoa, millet
  • Potatoes, sweet potatoes
  • Oils, vinegars without malt
  • Gluten-free oats

People with celiac disease need to choose gluten-free substitutions for staples like bread, pasta and baked goods. There are many high-quality gluten-free products available, made with ingredients like rice, corn, potato starch and quinoa.

Is Olive Oil Gluten-Free?

Yes, pure olive oil that is not contaminated with gluten is considered gluten-free and safe for people with celiac disease.

Olive oil is extracted from olives, which are fruits that do not contain any gluten proteins. The process of making olive oil simply involves crushing olives into a paste, then separating the oil from solids. No gluten-containing grains are used.

Here are reasons why pure, uncontaminated olive oil is gluten-free:

  • Olives do not contain gluten.
  • Olive oil is made by pressing olives, not grains.
  • No gluten ingredients are added during processing.
  • Olive oil has no detectable gluten protein.
  • Reputable brands test olive oil to confirm gluten-free status.

The Celiac Disease Foundation, Celiac Support Association and other reputable organizations consider pure olive oil to be safe for celiac diets as long as it has not been contaminated or adulterated with any gluten sources.

Is Extra Virgin Olive Oil Gluten-Free?

Yes, extra virgin olive oil that is produced properly without cross-contamination is considered gluten-free. Extra virgin olive oil comes from the first pressing of olives and tends to have a richer flavor. No gluten grains or additives are used in the production of extra virgin olive oil. Reputable producers will label olive oils as gluten-free and test them to verify their gluten-free status.

Are Flavored Olive Oils Gluten-Free?

Plain olive oils are reliably gluten-free. However, some flavored olive oils may contain added ingredients that contain gluten, such as spices, herbs or emulsifiers. It is important to read the label and confirm that no gluten-containing additives were used. If the flavored olive oil is labeled as gluten-free, it has likely been tested.

Cross-Contamination Risks

While pure olive oil is gluten-free, there is a risk of cross-contamination during harvesting, processing and packaging:

  • Gluten grains may be processed on same equipment.
  • Grain flours may be used to filter some oils.
  • Packaging facility may process gluten items.

To avoid any potential for cross-contamination, look for olive oils that are:

  • Labeled gluten-free or tested for gluten
  • Produced in a gluten-free facility
  • Packaged in a facility avoiding gluten

Reputable olive oil companies will take steps to avoid cross-contamination and regularly test for gluten during production.

Benefits of Olive Oil for Celiac Disease

  • Vitamin K – Important for blood clotting and bone health.
  • Plant compounds – Polyphenols act as antioxidants and may help reduce inflammation.

The overall fat and calorie content of olive oil is similar to other plant oils. However, olive oil contains very little saturated fat and is recognized as a healthy replacement for butter, margarine and vegetable oil spreads.

Here is a nutritional comparison between 1 tablespoon of olive oil and canola oil:

Nutrient Olive Oil Canola Oil
