What to Eat With Coeliac Disease: A Dietitian's Starter Plan

If you've just been diagnosed with coeliac disease, there’s a chance you've probably already Googled "coeliac diet plan" more times than you want to admit. And likely, what you found was either overwhelming, contradictory, or a big list of what you can't eat.

Instead, let’s focus on what you actually can eat - and how to build a coeliac disease meal plan that's balanced, satisfying, and doesn't take over your life.

First, a quick fact check

Maybe you’ve seen this in online support groups: someone reassuring a newly diagnosed person that coeliac disease is "just a dietary restriction" and pointing them to a list of resources. The resources part is genuinely good advice - Coeliac Australia is a great starting point and I strongly encourage anyone with coeliac disease to know it exists.

But the "just a dietary restriction" part undersells the bigger picture. Coeliac disease is an autoimmune condition. Gluten triggers the immune system to attack the small intestine, and as you probably already know - a strict, lifelong gluten free diet is currently the only treatment. That has knock-on effects worth taking seriously - nutrient absorption, bone health, gut health, monitoring for other autoimmune conditions, and the very real and daily mental load of navigating cross-contamination, label reading, travel and eating out safely, for life.

While it might seem overwhelming, it is not something that needs to be feared. However, it DOES deserve more than a one-line reassurance - which is exactly why a starter plan like this one exists - before you get the chance to chat in person to a dietitian experienced in coeliac disease.

The foundation: naturally gluten free foods

Before you even think about gluten free substitute products, remember that most whole foods are naturally gluten free. Building your plate around these foods first makes everything else a lot easier:

- Protein: meat, poultry, fish, eggs, tofu, legumes, plain nuts and seeds
- Carbohydrates: rice, potato, quinoa, buckwheat, polenta.
- Fruit and vegetables: all of them, fresh or frozen, in their whole form
- Dairy: milk, plain yoghurt, cheese (always worth a quick label check on flavoured varieties)
- Fats: olive oil, butter, avocado

None of these need a "gluten free" label, because gluten was never naturally in it to begin with. Be aware that sometimes these foods can be labelled with a ‘may contains gluten’ statement (which is something that a coeliac dietitian can help you understand how these foods apply to your personal situation).

But for the most part, a large part of your coeliac disease meal plan doesn't have to involve buying anything too different than before at all.

Building a balanced plate

A simple way to structure gluten free meals without overcomplicating it:

1. Fill a quarter of your plate with protein
2. Fill a quarter with a gluten free carbohydrate
3. Fill the remaining half with vegetables or salad
4. Add a source of healthy fat

This structure matters for coeliac disease specifically, not just as generic "healthy eating" advice. Getting enough fibre, iron, calcium and B vitamins is something to pay closer attention to on a gluten free diet, since some of the products that replace gluten containing staples are lower in these nutrients than their regular counterparts. A dietitian can help you check whether your particular diet is meeting these needs - that's not something a quick Google search can assess for you.

A sample day of eating

• Breakfast: Greek yoghurt with fruit, wholegrain gluten free cereal and a sprinkle of seeds, or eggs on gluten free toast
• Lunch: A rice or quinoa bowl with protein, roasted vegetables and a simple dressing
• Dinner: Grilled fish or chicken, roast potatoes, and a big side of vegetables
• Snacks: Fresh fruit, a handful of nuts with sliced cheese, roasted chickpeas, plain yoghurt, or vegetable sticks with hummus or cottage cheese.

Notice that gluten free bread, pasta and packaged products are optional extras here, not the backbone of the day. They're genuinely useful for convenience, and enjoyment, but a coeliac diet plan built entirely around gluten free packaged substitutes tends to be more expensive and potentially less nutritionally balanced than one built around naturally gluten free whole foods.

Where things get more complicated

This is the part that's harder to cover in a blog post, and honestly, harder to get right from a Facebook group or an AI chat: cross-contamination in the kitchen, understanding "may contain" statements on labels, eating out safely, and working out your own comfort level around trace gluten. These aren't one-size-fits-all answers as they depend on your specific situation and where you are at in your journey in regard to your symptoms, test results and degree of healing.

This is exactly what I help clients work through in the Coeliac Intensive - a longer session designed for anyone who's newly diagnosed and wants to go from "what am I even allowed to eat" to feeling genuinely confident in the kitchen, at the supermarket, and eating out.

Frequently Asked Questions

Do I need a special "coeliac diet plan," or is any gluten free diet fine?

A gluten free diet is the essential first step, but coeliac disease also raises the risk of nutrient gaps in areas like fibre, iron, calcium and B vitamins. A coeliac-specific meal plan accounts for this, rather than just removing gluten and leaving the rest to chance.

Is a gluten free diet automatically a healthy diet?

Not necessarily. Many gluten free packaged products are lower in fibre and higher in refined starches than their regular counterparts. The healthiest approach centres on naturally gluten free whole foods, with gluten free packaged products used for convenience rather than as the foundation.

How do I get started on a coeliac disease meal plan after diagnosis?

Start with naturally gluten free whole foods, learn to read labels for hidden gluten, and get comfortable with the kitchen and pantry basics. Many people find it helpful to work through this with a dietitian who specialises in coeliac disease, so nutrient adequacy and practical strategies are covered from the start, rather than worked out through trial and error.
