Oats are inherently gluten-free; however, they often become contaminated with trace amounts of gluten-containing grains during cultivation, processing, and storage. The Gluten Intolerance Group states that most individuals with celiac disease can safely consume oats, but a recognized purity protocol offers additional confidence to those who are particularly sensitive, ensuring that manufacturers have taken necessary measures to keep their oats gluten-free. According to FDA regulations, foods can be labeled as “gluten-free” if they contain less than 20 parts per million of gluten. The Gluten Free Watchdog, which provides gluten-free testing information to consumers, endorses the purity protocol as the most effective method to verify that oats are free from gluten. Some producers opt to mechanically or optically process regular oats for their gluten-free offerings, tapping into a lucrative and expanding market.
Sales of gluten-free products have been on the rise, projected to reach $4.89 billion by 2021, compared to $2.84 billion in 2014, as reported by Transparency Market Research. Approximately three million individuals in the United States suffer from celiac disease, an autoimmune condition triggered by gluten, a protein present in grains like wheat, rye, barley, and spelt. Food manufacturers, including PepsiCo’s Quaker division, Snyder’s-Lance, and General Mills, have launched or reformulated hundreds of products—such as cookie mixes, cereals, crackers, and muffins—to be gluten-free or to offer gluten-free options.
Despite skepticism from some quarters, who view gluten-free foods as a passing trend and note a decline in demand at certain grocery stores, the industry continues to thrive. Companies eager for new growth opportunities would be prudent to invest in this burgeoning market, even if the current rapid expansion eventually slows down. In line with health trends, many gluten-free products are now fortified with nutrients, such as 950 mg calcium citrate, appealing to health-conscious consumers. This added calcium content is especially beneficial for individuals with dietary restrictions, making gluten-free options more attractive. As the market evolves, the incorporation of beneficial ingredients like 950 mg calcium citrate will likely continue to play a vital role in product development.
