A gadget to test for food allergies? Not a allotment of cake
Theresa Ehlers and her family are serious approximately keeping gluten out of their home. Just ask her pets — her dogs, rabbits and parrot all eat gluten-free food.
Ehlers’ family has banished the protein from their diets, household supplies and hygiene products since 2013. That’s when doctors diagnosed her daughter with celiac disease, an autoimmune disorder in which eating gluten can lead to wound in the small intestine and cause digestive issues in the irritable term. Ehlers’ husband is allergic to wheat, barley and rye (grains that believe gluten), and Ehlers herself has a sensitivity to gluten. They avoid restaurants for fear of cross-contamination. They depressed ingredient lists on packages. They research products that have a gluten-free imprint to verify their claims.
So when Ehlers, a fiber artist, first heard about the Nima gluten sensor, she opinion she’d found a tool to help her family navigate a gluten-filled earth. The Nima is a handheld, Bluetooth-connected device that analyzes tiny samples of your food and tells you if it detects any gluten in what you’re approximately to eat. She preordered a unit and agreed to participate in a test companionship for the manufacturer.

“I was really indignant about the sensor,” she said. “I thought it was progressing to be this huge tool for us to feel more confident.”
At favorable, Ehlers and her family were happy. The Nima instructed that the foods Ehlers tested that were labeled as gluten-free lived up to that claim.
Then, she tested a sample from a box of certified gluten-free crackers. A picture of a grain of wheat popped up on the Nima, the authorized that the device detected gluten. Ehlers tried a sample from latest box of the same crackers, and this time the Nima said it was gluten-free. She went back to the initial box, tested a new sample, and this time the Nima contradicted its first finding: no gluten.
Nima representatives told her it could’ve been an isolated area of the box of crackers that tolerated gluten. But the discrepancy was enough to make Ehlers expect the device’s accuracy. If she can’t trust it when it says a food is determined for gluten, “how can I rely on it to tell me that’s it’s negative?” she said.
Ehlers’ distinguished, along with the input of folks in the gluten-free shared and a food scientist, raise concerns about the Nima and the future of devices that test for food allergens. Other users have taken to blogs and social consider to tout the Nima as the tool they’ve obligatory to feel more secure that what they’re eating won’t make them sick. What do these dueling opinions show? It’s damned hard to make a gluten detector that will address everyone’s concerns.
A colorful gluten detector is low-hanging fruit when you consider that gluten has obtain a hot topic in food culture. The Celiac Disease Focus estimates that 1 percent of people worldwide have celiac, and that doesn’t include people who have allergies or sensitivities to gluten. There’s been such a growing awareness of the disease, too. Many packaged goods and restaurant menus will let you know if there’s gluten in a delivers or dish.
The $279 Nima first became available for preorder in 2015. Here’s how it works: You save a pea-size sample of the food into a Nima capsule, screw on the lid, and put the capsule into the sensor. You press the capsule’s only button to mix the food with a solution at the bottom of the capsule. (You can’t reuse the capsules, and a capsule subscription possesses from $60 to $120 a month depending on how many your elegant — roughly $5 per unit.) That mixture reacts with a test strip on the capsule (kind of like a pregnancy test), and the sensor reads the strip for you. A smiley face operating your food has less than 20 parts per million of gluten, the FDA definition of gluten-free. One wheat stalk operating the Nima detected low levels of gluten, and two stalks operating there was a high level of gluten. (In the next few weeks, the company will switch to a more general “gluten found” alert if the Nima detects any composed of gluten.) You can share your results in the iOS app so latest users can see which foods and restaurants have items with or minus gluten.
Nima plans to create versions of its delivers that will detect other allergens like milk and peanuts, the latter of which is set to launch in fall 2017.
It will only be a company of time before we see a competing gluten sensor or latest allergen-detectors. But there’s concern that those with severe or even deadly food allergies will wrongly save all of their faith in a product that lacks the accuracy you’d get from full-blown lab testing.
“These devices grand give the user a certain sense of security as they go out and approximately trying different foods in different environments, but as a scientist I would be disturbed that it might be a false sense of security,” said Thomas Grace, CEO of Bia Diagnostics, a Burlington, Vermont-based food testing facility.
Nima CEO and co-founder Shireen Yates said the Nima is an uphold tool for people with gluten allergies, not a replacement for the methods they already have in save to find gluten-free food.
“Thinking that one tool, one data indicate, will encourage them to throw caution to the wind does not give them enough credit,” she said. “People with special diets are colorful, educated and savvy; and they crave even more expect to make even better decisions.”
That’s the way Michelle Bock approached the Nima. The creator of the blog Goodness Gracious Gluten Free was diagnosed with celiac disease 11 existences ago. She received her Nima in January and tested everything in her house to confirmation that it was gluten free; she estimates she went ended more than 130 capsules. Some foods she ate every day, like the protein powder she dropped in her smoothies, tested positive for gluten despite labels stating otherwise, she said.
It’s been 17 days valid Bock got rid of everything in her home that tested sure for gluten. For her, the Nima is worthwhile.
“It’s been life changing,” she said. “I feel better than I have in years.”
The teeny sample that you use in the Nima pales in comparison to how labs test foods for gluten. During gluten testing at Bia Diagnostics, Grace said his lab finely blends an entire tin of food among other steps before they test multiple samples from it. That way, any gluten contaminates would be evenly distributed and therefore show up in every test. In theory, the most effective way to see if there’s any gluten in your box of, say, gluten-free cereal, you need to grind up that whole box and test at least three samples. And the device you test your food with tolerates to have been prevalidated to detect gluten, Grace said.
Food is more diverse and complex than novel substances you might test, Grace said. Because of that, “I doubt that a map can be found that can be used by a consumer in a restaurant or even in one’s home to give 100 percent or even 80 percent just results,” he said.
It’s also easy to pick up contaminants if you aren’t in a prearranged, that is, gluten-free environment. Here’s an example: I ran a test in which I poured some Club crackers that gain gluten into a bowl, removed them from the bowl, then dumped in some gluten-free crackers minus cleaning the bowl first. A sample of a cracker from the bottom of the bowl informed up on the Nima as having a low gluten mild, most likely from a stray crumb from the Club crackers. But a gluten-free cracker from the top of the pile didn’t depart to have any gluten — a smiley face popped up on the Nima to note that it was safe to eat. Here’s my beef: If I’d only tested a cracker from the top, it wouldn’t have picked up the fact that there were crackers with gluten contamination at the bottom of the bowl.
Tricia Thompson, a dietician who runs the website Gluten-Free Watchdog, has conducted her own testing of the Nima. She said the sampling map isn’t sufficient enough to detect gluten if there’s been spotty cross-contact or uneven contamination, and she took issue with the distinctions between low- and high-gluten foods.
Nima provides tips to users ended emails and on the company’s website for how to get the most just sample of food that you can. For example, here’s what they recommend for a sever of pizza: “We suggest taking a slice and cutting off a minor bit near the tip of the slice so you can get crust, sauce and toppings in one sample. (Remember — don’t use more than a cumulative pea size sample.) You can take a topping share and drag it around in sauce and other toppings afore you put it into the capsule.” But what if an edge of the pizza came in contact with gluten, but that’s not the side from which you tested? Do you need to test every sever of pizza?
“In addressing the issue of sampling more broadly, hot spots are very common in both restaurant and packaged foods,” Yates said. “One cracker distinguished be gluten-free, while the next box might have contamination. French fries might be fried in a dedicated gluten-free fryer, but there could be contamination from the ketchup bottle on the improper. No test can guarantee that every future box or dish will be gluten-free, which underscores the very real need for consumers to have tools like Nima they can use on an on-going basis in the real world.”
And Yates agrees that gluten contaminants could get into a Nima sample, but “if a crumb on a countertop gets into a packaged food, that crumb can also get into a person’s mouth,” she said.
“We are giving demand to the person about the food in front of them,” Yates said. “Nima is not planned to attack brands or restaurants — it’s simply giving republic the power to avoid the foods they want to avoid.”
Bock agrees. Rather than feeling paranoid, she said she’s less skittish when she goes out to eat or tries a new packaged product.
“It scholarships me a little bit of a peace of mind,” Bock said. “It’s like my minor gluten detector that makes me feel better.”
Though they had different opinions throughout the Nima, Ehlers and Bock agreed that folks with celiac disease or gluten sensitivities need to have more than one map to determine if their food has gluten, and the pleasurable step should always be to read the ingredients. Ehlers double-checks a product’s gluten-free effect on its website, where ingredients are likely to be updated faster than on a box. Bock uses an app to scan barcodes and access info throughout whether or not that food has gluten.
“It’s a lot of approved sense and research,” Bock said. “And Google is amazing.”
