What Is The Best Diet for Gluten Intolerance and Celiac Disease?
If you have gluten intolerance or celiac disease, one of the most important things you can do for your health is follow a strict gluten-free diet.
As someone who has experienced my own digestive discomfort after eating certain gluten-containing foods, I understand how frustrating it can be. For some people, symptoms may be relatively mild, while for others, exposure to gluten can trigger severe digestive problems and nutritional deficiencies.
The good news is that living gluten-free is much easier today than it was even a few years ago. Supermarkets, restaurants, and food manufacturers now offer more gluten-free choices than ever before.
In this guide, I’ll explain what gluten intolerance and celiac disease are, which foods to avoid, which foods to enjoy, and how to build a healthy gluten-free diet in 2026.
What is Gluten?
Gluten is a group of proteins naturally found in:
- Wheat
- Barley
- Rye
It helps foods maintain their structure and texture, which is why it is commonly found in bread, pasta, cakes, cereals, and baked goods.
For most people, gluten causes no problems. However, for those with gluten intolerance or celiac disease, consuming gluten can trigger unpleasant symptoms and health complications.
Gluten Intolerance vs Celiac Disease
Although these conditions are often discussed together, they are not the same thing.
Gluten Intolerance (Non-Celiac Gluten Sensitivity)
People with gluten intolerance may experience symptoms such as:
- Bloating
- Gas
- Stomach pain
- Diarrhea
- Fatigue
- Brain fog
- Headaches
These symptoms often improve when gluten is removed from the diet.
What Is Celiac Disease?
Celiac disease is an autoimmune condition.
When someone with celiac disease consumes gluten, their immune system attacks the lining of the small intestine. Over time, this can damage the intestine and reduce the body’s ability to absorb important nutrients.
Potential consequences include:
- Iron deficiency
- Low calcium levels
- Vitamin deficiencies
- Weight loss
- Fatigue
- Anaemia
- Osteoporosis
For people with celiac disease, even small amounts of gluten can cause problems, making strict avoidance essential.
What Are Foods that Contain Gluten?
If you are following a gluten-free diet, the first step is learning where gluten hides.
Common foods that contain gluten include:
- Bread
- Pasta
- Cakes
- Biscuits
- Pastries
- Pizza
- Breakfast cereals
- Crackers
- Beer
- Couscous
Gluten can also appear in less obvious products such as:
- Soy sauce
- Gravy mixes
- Some soups
- Marinades
- Processed meats
- Seasoning blends
Always check ingredient labels carefully.
Hidden Sources of Gluten
Many people focus on bread and pasta but forget about cross-contamination.
Examples include:
- Oats processed in facilities that handle wheat
- Shared toasters
- Restaurant preparation surfaces
- Fryers used for breaded foods
- Shared kitchen utensils
If you have celiac disease, reducing cross-contamination is just as important as avoiding gluten-containing foods.
Naturally Gluten-Free Foods
The good news is that many nutritious foods are naturally gluten-free. While avoiding wheat, barley, and rye may seem challenging at first, there are still plenty of healthy options to build balanced meals around.
| Category | Examples |
|---|---|
| 🥩 Protein Sources | Meat, poultry, fish, eggs |
| 🥦 Fruits & Vegetables | Almost all fresh fruits and vegetables |
| 🥜 Nuts & Seeds | Almonds, walnuts, pumpkin seeds, chia seeds, sunflower seeds |
| 🌾 Gluten-Free Grains & Pseudograins | Rice, corn, quinoa, millet, sorghum, buckwheat, amaranth |
| 🥣 Certified Gluten-Free Oats | Oats labelled and certified gluten-free |
Many of these foods are excellent sources of protein, fibre, vitamins, minerals, and healthy fats. Building your diet around naturally gluten-free whole foods can make it much easier to avoid accidental gluten exposure while supporting overall health.
Tip: If you choose oats, always look for a certified gluten-free label. Although oats do not naturally contain gluten, they are often processed in facilities that also handle wheat, barley, and rye, which can lead to cross-contamination.
Best Gluten-Free Breakfast Idea
One of my favourite breakfasts is:
Porridge Oats with Blueberries, Almonds, Cinnamon and Honey
Just to be clear make sure you are using gluten-free porridge oats. Whilst oats themselves do not contain gluten there is also the risk that on the production line they can become cross-contaminated. Gluten-free oats are produced in an environment that is specifically made clean for this purpose.
I often make this for myself for breakfast. Porridge Oats which I boil in water with a bit of milk which I add when it starts to simmer followed by Cinnamon Powder, then Almonds, and Blueberries topped off with Honey. No sugar needed. If you make this right it is very tasty and good for you.
This creates a filling breakfast rich in fibre, antioxidants, vitamins, and minerals.
Best Gluten Free Lunch Idea
This might not be an obvious choice – Pizza is typically terrible for its gluten in the base. I stopped eating Pizza for a long time for this exact reason but for people that still love pizza and hate not being able to eat it – there is an alternative that you may want to give a try.
Gluten Free Pepporoni & Mozerella Cheese Pizza
This is not the only recipe. There are actually a variety of ingredients that you can make a gluten free pizza base with but for example here is a recipe I found during my research:
- 400g of Gluten-Free Bread Flour ~ Usually made with Rice Flour, Tapioca and Potato with xanthan gum used as a thickener.
*It is recommended to buy this ready-made. - 2 tbsp of Gluten-Free Baking Powder ~ Made with Corn Flour, Cream of Tartar and Baking Soda
- 1 heaped tsp Xanthan Gum
- 5 tbsp Olive Oil
- 2 heaped tbsp Golden Caster Sugar
- 1 tbsp off Fine Salt.
- 250 ml of Warm Water
Note: You do not need to use eggs for this recipe so providing what topping you use this can be 100% vegan friendly too if this is something else.
How To Make the Gluten Free Pizza Base ~
- Mix the Flour, Baking Powder, Xanthan Gum, Salt and Golden Sugar in a large mixing bowl. Then next thing, make a well in the middle and add the warm water and olive oil. Act quickly to create a paste-like texture both wet and thick. Add another 20ml of warm water if dough mixture feels too dry.
- Next cover in an airtight container and place in the fridge for 24 hours. Then once ready lightly flour 2 baking sheets and split the mixture into 2 and roll into 2 round bases.
- Once done, add to base homemade tomato sauce. Ingredients to use 400g chopped tomatoes, 2 tbsp tomato puree, and finely diced onion. Add also 2 tbsp of olive oil and if you like crushed garlic 1 clove & 1 tbsp of caster sugar.
On top of base finally, add chopped basil leaves, buffalo mozzarella sliced and Pepperoni.

Can Digestive Enzymes Help?
Some people use digestive enzyme supplements containing DPP-IV enzymes as additional digestive support.
While these supplements may help break down certain gluten proteins, they should never be viewed as a replacement for a gluten-free diet, especially for people with celiac disease.
If you have celiac disease or severe gluten sensitivity, always speak with your doctor before using supplements for this purpose.
Obviously take care if this is something you decide to try but if you are Interested you can find out more by reading my gluten guardian review here<<

I can’t believe there is a great recipe for a gluten free pizza! I tried it out and it tastes amazing so I just wanted to say a big thank you for sharing it! Do you have any more recipes?
Thanks again for your help, you have brought so much joy back to my life.

Thank you, Nelson. Appreciate you taking the time to leave a comment.

Hello, this is a very awesome piece and a very detailed one. I’m really happy I came across this as the information I’m getting from here is standard. I have an aunt with celiac disease, her case was the first I heard of it and this information would be of great use to her. I really don’t understand the disease because I don’t live close to her, only heard it on the phone. I’ll forward this to her tho so she can have this information.
Thanks Lizzy that would be awesome
