How much Gluten is in a Gluten-Free Diet?

A gluten-free diet is a diet very low in gluten to levels which in Australia is undetectable. 


Currently, this means there is less than 3 parts per million (3 ppm) which = 0.0003g gluten per 100g of food.

How to Identify Gluten-Free FOODS

1. Naturally Gluten-Free FOODS

Foods that naturally do not contain gluten are fresh fruits and vegetables, plain milk and cheese, nuts and seeds, eggs, unprocessed meats, legumes (beans and lentils), fats and oils and naturally gluten free grains. These naturally gluten-free foods can be eaten freely.

Beware if these foods if they have been modified such as marinating, or processed with different ingredients as gluten may have been added a s a result. 

Naturally gluten-free grains

There are many grains and flours that do not contain gluten that can be used safely in the gluten-free diet such as:

Almond meal, amaranth, arrowroot

Besan flour (=chickpea flour), buckwheat

Carob, coconut flour

Corn (= maize), cornmeal, polenta

Gluten free flour mixes


Lentil and lentil flour, lupin

Millet (= teff)

Potato flour, psyllium


Rice & rice flour/bran etc

Sago, sorghum, soy flour, soy bean

Tapioca, teff

To be able to use these grains effective for example to make gluten-free bread there are a lot of tricks and suggestions to try and mimic the wonderful qualities of gluten.

2. Labelled gluten-free

3. Products endorsed by Coeliac Australia

The following logo is endorsed by Coeliac Australia so if a food has this logo on its packaging, you can include the food in your gluten-free diet.

4. Ingredients are gluten-free

If the food is not labelled gluten-free or endorsed by the Coeliac Society then you can check the ingredient list to see if the food contains any gluten.

Learning to read labels is an important skill in identifying appropriate gluten free foods. I can enable you to read labels and identify if an ingredient is gluten-free or may contain gluten.

It is also useful to join the Coeliac society to receive an ingredient list booklet to help you determine which food ingredients are gluten free or contain gluten, along with the Coeliac Society app.
