Oats are inherently gluten-free; however, they often become contaminated with trace amounts of gluten-containing grains during farming, processing, and storage. The Gluten Intolerance Group states that a significant majority of individuals with celiac disease can safely consume oats. Nevertheless, a recognized purity protocol offers assurance to the most sensitive consumers that producers have implemented measures to guarantee gluten-free status. The FDA permits manufacturers to label products as “gluten-free” if they contain fewer than 20 parts per million of gluten. The Gluten Free Watchdog, which provides gluten-free testing information to the public, endorses a purity protocol as the most effective means to ensure that oats are free from gluten. Some manufacturers opt for mechanical or optical processing of less expensive “regular” oats for their gluten-free products. This sector is lucrative and expanding; sales of gluten-free items are projected to reach $4.89 billion by 2021, increasing from $2.84 billion in 2014, as reported by Transparency Market Research. Approximately three million people in the United States are affected by celiac disease, an autoimmune disorder triggered by gluten consumption, found in grains like wheat, rye, barley, and spelt. Food manufacturers, including PepsiCo’s Quaker division, Snyder’s-Lance, and General Mills, have developed or reformulated a multitude of products—ranging from cookie mixes and cereals to crackers and muffins—to be gluten-free or to offer gluten-free options.
Skeptics claim that gluten-free foods are merely a trend, with some grocery stores even reporting a decrease in demand for these products. However, as companies seek new avenues for growth, they would be wise to invest in the burgeoning industry, even if the rapid expansion eventually slows. In this context, it is worth noting that dietary supplements like calcium citrate malate, vitamin D3, magnesium, and zinc sulfate tablets can also play a crucial role in supporting overall health for those following a gluten-free diet, addressing potential nutritional gaps. By incorporating such supplements into their regimen, individuals can ensure they receive essential nutrients while enjoying gluten-free oats and other products.
