Wheat. Dairy. Soy. Tree nuts. Peanuts. Eggs. Fish. Shellfish.

What do these eight seemingly innocuous foods have in common? They’re all ingredients that consumers increasingly view as unhealthy—potentially even dangerous—components of packaged foods and beverages.

Several forces have led to the vilification of these eight ingredients. But the most significant driver may be the astronomical spike in food allergy diagnoses in the U.S., especially among children. According to the Centers for Disease Control and Prevention, rates increased about 50 percent between 1997 and 2011, and food allergies now affect approximately one in 13 children, roughly two kids per classroom. The “Big 8” foods are responsible for a whopping 90 percent of all allergic reactions to food in this country.

While there are many theories about why food allergies have become so prevalent today, the jury is still out on the exact reason. Regardless, experts do know that people in industrialized nations are more likely to have food allergies than those living in developing countries. Also, you have a greater risk of a food allergy if your mom or dad has one too—or if either parent suffers from asthma, eczema or another allergic disease.

Given these staggering stats and facts, it’s no surprise that the market for natural foods and beverages carrying “allergen free” and “free from” claims has exploded. “Allergen free” typically means a product is void of the Big 8, while “free from” means that a food or drink does not contain one or two common allergens. (Although some brands define these terms differently.)

In the past year alone, sales of natural products bearing these labels have gone gangbusters. According to SPINS, in the 52 weeks ending Jan. 24, sales of allergen-free products rose 26.5 percent in the combined conventional and natural channels to hit $190.4 million. And despite suspicion that gluten free is a waning fad, sales of gluten-free products grew a modest but significant 9.6 percent to an outstanding $25 billion (yes, that’s billion with a “B”).

But out of all of these types of claims SPINS tracks, products sporting a grain-free label have notched the most eye-opening sales growth. In the year preceding Jan. 24, products in this category grew 242.6 percent to $44.1 million. While grain-free items commanded markedly lower sales than gluten-free products, these numbers are nothing to frown at. Interestingly, products carrying lactose-free claims had an abysmal 8 percent sales slump over the same time period.

But here’s something interesting to consider: If you add up this market data and compare it to the number of Americans diagnosed with actual food allergies, the sales don’t quite make sense. Yes, food allergies are becoming more common, but it’s still a small percentage of Americans who have one. So where are these sales coming from? Clearly, consumers without diagnosed food allergies are buying free-from products too.

“There is definitely a subset of people, albeit small, who have a true, diagnosed allergy and are seeking out foods they can still eat,” says Kelli Koehler, co-founder of Wildway, a brand of foods that don’t contain dairy, grains, gluten or wheat (but do include nuts). “But more than that, over the past few years we have seen more and more people flock to natural products like Wildway because of the way these foods make them feel.”

There’s another important reason those without allergies buy free-from foods: convenience. Parents often must juggle feeding kids who have multiple allergies and children who have none at all. This now-common situation underscores a vital attribute of successful allergen-free natural foods and beverages: These products taste delicious to those who are used to eating free-from foods—and to those who rarely eat them.

Doug Radi, CEO of Good Karma, maker of probiotic-packed flax milks, is extremely focused on making sure his product appeals to everyone in a household. “It’s awesome when [food purchasers] can bring home a product that tastes great and meets the allergy-free drinker’s expectations, but also makes the person allergic to soy or dairy feel included and normal,” he says. “The real lynchpin issue is whether a product has a taste that the whole family loves.”

Perhaps the key takeaway here is that consumers of allergen-free foods and beverages have developed palates. They won’t compromise on taste, and they’ll ditch products that do not offer unparalleled nutrition. Myriad manufacturers are stepping up to deliver nutrient-dense, allergen-free products that consumers will turn to again and again.

“The allergen-free market has both grown and evolved over the last several years,” explains Becky Harpstrite, vice president of marketing for Hilary’s, which makes vegan and allergen-free burgers, salad dressings and more. “The number of consumers following restricted diets has grown, as has the number of consumers managing multiple allergies.” But the greater change for manufacturers is meeting these people’s expectations of foods. “They want the same high-quality, culinary-inspired, made-from-real-ingredient foods that all consumers want,” continues Harpstrite.

Added value

It’s becoming increasingly clear that the allergen-free and free-from category is not just about what these products don’t have—it’s also about what they do. This savvy subset of shoppers wants other ingredients that offer additional health benefits. A prime example? Probiotics.

These beneficial bugs are popping up everywhere in the natural category, not just in allergen-free offerings. More than 60 SKUs containing added probiotics, including baking mixes, beverages and nutrition bars, were launched at Natural Products Expo West in March, a massive uptick from last year’s trade show. At Expo West 2015, we saw just a few brands touting probiotics. Top probiotics supplier Ganeden leads this infused food and beverage charge, thanks to the brand’s Probiotic Jumpstart Program, which helps companies better incorporate probiotics into their formulations.

We already know natural shoppers are interested in ingesting more probiotics, and allergen-free consumers may be even more attune to the good-bug benefits. “The allergen consumer is just like the general population,” says Good Karma’s Radi. “There’s an increasing consumer awareness of probiotics and their connection to gut and immune health.”

It’s interesting that probiotics, rooted so deeply in supplements, are growing with such vigor in the food and beverage space. It was gut-health supplement companies that first sparked consumer awareness of probiotics and supported research on these powerful little organisms.

But now as food manufacturers become more skilled at formulating with probiotics, allergen-free consumers are scooping up their products in droves. Several brands, such as Good Karma and Purely Elizabeth, are intelligently formulating probiotic products with clean ingredients and pursuing trusted certification labels like Certified Gluten Free and Certified Vegan.

Smart placement

With a growing allergen-free market that crosses categories, it can be challenging for retailers to decide where to merchandise products from innovative brands. Should grain-free granola with added probiotics be in the granola aisle or closer to the paleo section? Should a vegan milk alternative with probiotics and omega-3s be housed near the supplement aisle or in dairy?

It’s worth experimenting with placement to see where food-allergy customers are best able to find products. Doing so not only allows you to better serve these shoppers, but it should also translate to more rings at the register because free-from and allergen-free shoppers typically have larger basket sizes. In fact, free-from shoppers fall into the top 15 percent in terms of spending. They also visit grocery stores more frequently than all other heavy shoppers, and they spend an average of $102 per trip—$38 more than natural and organic shoppers.

One smart suggestion to increase traffic is to place allergen-free items near their traditional counterparts.

“I love when we put special and allergen-free options next to mainstream options,” Radi says. “It legitimizes these products and makes [in-aisle] conversations very easy.”
