In recent years, the availability of gluten-free foods has grown significantly in Spanish supermarkets. What was once a niche market for a very specific group has now become a common category on supermarket shelves. However, this increased variety is not always accompanied by true accessibility. For people with celiac disease, the need to follow a gluten-free diet is not a fad, but a medical condition that requires specific, safe, and, above all, affordable products.
The debate surrounding the price, quality, and convenience of these products has intensified in recent months, fueled by both industry data and stories of citizen solidarity. Furthermore, the recent case of actor Matt Damon, who eliminated gluten to prepare for his role in 'The Odyssey,' has reignited the discussion about whether it is truly beneficial to do without this protein without a prior diagnosis. Below, we analyze the key aspects of an issue that affects thousands of households in Spain.
The challenge of access and price in Spanish households
According to data from the Eroski supermarket chain, gluten-free products are present in 8% of Spanish households . Although they represent a small portion of total food spending, families who purchase them exhibit very active shopping behavior: they double their average annual spending, make 70% more trips to the supermarket, and spend 15% more per purchase. In households with children, penetration reaches 12%, reflecting a structural need for thousands of families.
Beatriz Santos, Commercial Director of Eroski, emphasizes that facilitating access to gluten-free food is not just about having the product on the shelf, but also about ensuring that price is not a barrier. "It's about eliminating barriers, building trust, and making it easy for everyone to access safe, high-quality food," she states. Trust in the brand is key, especially when it comes to guaranteeing the absence of cross-contamination and the traceability of ingredients.
Solidarity in times of crisis: gluten-free food for those affected by the fires
The need for these products becomes especially evident in emergency situations. A young man named Adrián Guerra, a resident of Móstoles, organized a food drive for the victims of the La Adrada fire in Ávila. Among the items he transported in his car were gluten-free foods, such as cakes, flour, and pancakes for people with celiac disease , as well as diapers and other essential supplies. Guerra explained that the residents under lockdown could sleep in their homes, but they needed specific supplies. After an initial delivery, he reloaded his car with more products purchased through donations via Bizum, demonstrating that community solidarity can overcome logistical challenges.
These types of initiatives highlight that, beyond the commercial supply, access to gluten-free food remains a logistical and economic challenge for many people, especially in rural areas or in crisis contexts.
The other side of the coin: Is it healthy to eliminate gluten unnecessarily?
Faced with increased demand, experts warn against eliminating gluten without a medical reason. Júlia Farré, an expert in human nutrition and dietetics, points out that "many people avoid gluten thinking it will make their diet healthier ," but they often end up eating worse. According to Farré, studies show that those who eliminate gluten unnecessarily tend to consume more processed, lower-quality foods. "For a healthy person who has no problem digesting gluten, its consumption will not cause any health problems," she concludes.
This warning is particularly relevant given the proliferation of products labeled "gluten-free" that, in reality, contain high levels of sugars and fats to enhance their flavor. María Sol Deserti, a graduate in Food Science and Technology who also suffers from celiac disease, reminds us that not all gluten-free foods are nutritionally sound and that it is essential to read labels and choose minimally processed options.
The Matt Damon phenomenon and the gluten debate
Actor Matt Damon has made headlines for his dramatic physical transformation to play Odysseus in Christopher Nolan's new film. Damon admitted to eliminating gluten from his diet, losing nearly 15 pounds, and claiming to feel much better. However, dietitian Edgar Sancho, specializing in clinical nutrition, clarifies that "eliminating gluten doesn't, in itself, lead to weight loss ." In the actor's case, the weight loss was due to an overall calorie deficit, the elimination of foods like pizza and beer, and intense training. "A gluten-free diet is necessary for celiac disease, but there is no solid evidence to recommend it as a weight-loss method for the general population," Sancho explains.
Damon himself has confessed that he misses bread and beer, but has found gluten-free alternatives. His testimony has served to highlight the difference between a medical necessity and a dietary trend, a nuance that is often lost in the headlines.
The combination of industry data, examples of solidarity, and expert warnings paints a complex picture. Advances in supply and awareness coexist with persistent challenges related to price, accessibility, and nutritional education. While families with celiac disease demand safe and affordable products, specialists remind us that eliminating gluten without a diagnosis can be counterproductive. The key lies in finding a balance that guarantees the right to adequate nutrition without falling prey to unfounded fads.
