Gluten: what it really is and why it shouldn’t be feared

Gluten is one of the most discussed ingredients in contemporary nutrition, often misrepresented in public discourse. Understanding its biochemical role and the actual evidence around it is a useful starting point for anyone trying to make sense of the conversation.

What gluten actually is

Science defines gluten as a continuous viscoelastic network made up of two types of proteins, gliadin and glutenin, naturally present in wheat and several other cereals. It has been a structural component of human diets for millennia, and its recent reputation as something to avoid is largely disconnected from the scientific literature.

The role of gluten in pasta

According to research published on PubMed, gluten is what gives pasta its:

  • structure
  • elasticity
  • cooking resistance

When flour is combined with water, gluten proteins (glutenin and gliadin) form a three-dimensional network. This network traps starch granules and gives the dough the strength needed to maintain its shape and achieve the characteristic “al dente” texture after cooking.
Without gluten, pasta would lose many of its defining qualities.

Who actually needs to avoid it

The World Gastroenterology Organisation’s global guidelines on celiac disease confirm that clinical indications for a gluten-free diet are specific and well-defined. Celiac disease is an autoimmune condition in which gluten triggers an immune response that damages the intestinal mucosa. Non-celiac gluten sensitivity is a separate condition, characterized by symptoms that occur without the autoimmune mechanism, and should be assessed and confirmed by a healthcare professional. Outside these diagnoses, there is no evidence-based justification for eliminating gluten. For those who do need to avoid it, pasta makers have developed gluten-free alternatives over the years that allow even those with celiac disease or diagnosed sensitivities to enjoy a proper plate of pasta. 

The gluten-free trend

The commercial expansion of gluten-free products has outpaced the clinical rationale behind them. As the American Gastroenterological Association points out, for individuals without a medical indication these products frequently offer lower fiber content, a less favorable nutritional profile and a higher degree of industrial processing compared to their conventional equivalents. The absence of gluten does not, in itself, make a product healthier. 

A more grounded perspective

Gluten is a naturally occurring component of the Mediterranean dietary pattern, present in foods with a long and well-documented nutritional history. Approaching it with the same critical thinking applied to any ingredient, rather than reflexive avoidance, tends to lead to more balanced and better-informed dietary choices.
