The term “gluten-free” has become a popular dietary catchphrase since the 1940s, but are these foods truly healthier? Some researchers from Clemson University suggest that they might not be, after all.
Researchers Sachin Rustgi, Tariq Alam, and Guatam Saripalli at the Clemson Pee Dee Research and Education Center in Florence, South Carolina, conducted a study comparing 39 gluten-free products to their gluten-containing counterparts. Their findings may surprise many consumers.
“Our study revealed that, on average, gluten-free products available to U.S. consumers contained significantly less protein and more sugar and calories than their gluten-containing counterparts,” Rustgi explained. “Additionally, gluten-free products tend to be more expensive.”
These findings are particularly significant for individuals with celiac disease, wheat allergies, or non-celiac wheat sensitivity, as well as those who opt for a gluten-free lifestyle for personal reasons rather than medical necessity.
Gluten intolerance and its impact
Gluten, a protein found in wheat, is linked to several disorders, most notably celiac disease. Celiac disease is a chronic digestive condition that occurs in individuals who are genetically predisposed to it. For those affected, consuming gluten triggers an immune response in the small intestine, leading to damage and nutrient malabsorption. About 1% of the global population is estimated to be affected by this disease.
In addition to celiac disease, a wheat allergy can cause severe reactions when individuals eat or come into contact with gluten. Non-celiac wheat sensitivity, where people experience symptoms after consuming wheat but do not have celiac disease or a wheat allergy, is also a recognized condition.
For individuals diagnosed with any of these conditions, avoiding gluten and wheat products is essential. However, in the U.S., many consumers believe gluten-free foods are inherently healthier than their gluten-containing alternatives.
A potential downside to gluten-free diets
While gluten-free diets are vital for managing certain medical conditions, there are potential health risks for those who follow such diets without medical necessity.
“Following a gluten-free diet that’s not medically prescribed can lead to deterioration of gut health, including a reduction in beneficial bacteria,” Alam warned. “This reduction can increase harmful bacteria in the gut.”
The researchers also highlighted that gluten-free diets can lead to nutritional deficiencies and changes in body mass index, ultimately increasing vulnerability to other health issues.
The challenges of gluten-free products
Many gluten-free foods use alternative ingredients such as corn starch, potato flour, or tapioca flour, which may lack the nutritional value of wheat. Furthermore, gluten-free products in the U.S. may still contain trace amounts of gluten, as the FDA allows a reduced gluten level of 20 mg/kg.
The researchers emphasize that current gluten-free products may not adequately replace traditional cereal-based foods in terms of both nutrition and quality. The lack of an official prescription list for gluten-free foods in the U.S. highlights a gap in dietary support for those with gluten-related disorders.
Recommendations for better support
To better support individuals with celiac disease, wheat allergies, or wheat sensitivity, the researchers suggest the development of a gluten-free prescription list. Such a list could guide dietitians, nutritionists, and policymakers in creating more effective, nutritionally balanced gluten-free alternatives.
In conclusion, while gluten-free diets are essential for those with medical needs, they may not always be the healthier choice for the general population. It is important for consumers to be aware of the potential health risks associated with gluten-free foods and consider their choices carefully.
