What is gluten?

Gluten is the name given to two proteins, glutenin and gliadin that are found in wheat, rye, oats, and barley or any products tehreof.¹ You can develop a sensitivity (a gluten intolerance) or have an adverse reaction to it (coeliac disease).

What is a gluten intolerance?

Gluten intolerance or non-coeliac gluten sensitivity (NCGS) happens when your body can’t digest gluten⁴. This condition shows itself through a variety of symptoms, including bloating, abdominal pain, gas, diarrhoea, constipation, and headaches⁵. It is recommended that you at least cut down or completely eliminate gluten from your diet if you have this condition.

Which foods contain gluten?

A lot of foods are naturally gluten-free when you get them raw and unprocessed, e.g., meat, fish, vegetables, legumes, pulses, rice and other grains.⁶

Flour

Going down the bakery isle can be nightmare when you’re avoiding gluten. How are you supposed to make a cake for your gluten-free guest at your dinner party? Is freshly baked bread out of the question? No and no! Find out the ingredients you need to avoid, and which gluten-free alternative is best for your needs

Other gluten-free flours: oat flour, millet flour, quinoa flour, flaxseed meal, amaranth flour, chestnut flour, and hemp flour.⁸ You can also get specially-made gluten-free flour for specific tasks, e.g. gluten-free bread flour, gluten-free self-raising flour, etc.

Always check packaging labels as some products may contain gluten and some may have cross-contamination warnings, for example they were made in a factory that also handles products containing gluten.

Are oats gluten-free? Oats don’t naturally contain gluten, but the way they are produced means sometimes they are not10. Make sure to check the label – like with anything if you are avoiding gluten.
