The Hidden Truth About Gluten-Free Diet: Benefits Your Doctor Never Mentioned The gluten free diet has skyrocketed in popularity. Americans spent more than $15.5 billion on gluten-free foods in 2016—double the amount from just five years earlier. While less than 1% of the U.S. population has celiac disease, roughly 20-30% of Americans have tried or currently follow a gluten-free lifestyle. This stark contrast between medical necessity and actual adoption makes us wonder what benefits drive so many people to eliminate gluten. Benefits of avoiding gluten go well beyond what doctors typically discuss with their patients. People who avoid gluten more than tripled between 2009 and 2014, which suggests many experience positive changes without a celiac diagnosis. Making this dietary choice can be challenging. Tools like the Food Scan Genius app help make it easier with its 35 customizable filters and AI technology. This piece will reveal the hidden benefits of a gluten free diet that your doctor probably never mentioned. Why gluten-free is more than a medical necessity The popularity of gluten-free diets has skyrocketed among people with no diagnosed conditions. The market for gluten-free products grew at an amazing rate of 28% each year between 2004 and 2011 [1]. Sales reached about $2.60 billion by 2012 [1] and experts predict this number will hit $6.60 billion by 2017 [1]. These numbers show that gluten-free living has spread way beyond people with celiac disease. The rise of gluten-free among healthy individuals Only 1% of people have celiac disease and 3-6% have non-celiac gluten sensitivity [2]. Yet about 25% of Americans ate gluten-free products in 2015 [2]. This gap suggests that roughly 20% of people pick gluten-free foods without any medical reason. NPD’s 2013 survey shows that 30% of Americans wanted to avoid gluten [1]. Another study found that 65% of American adults think gluten-free foods are healthier [1]. On top of that, a 2015 Nielsen survey of 30,000 adults worldwide showed that 21% of people rated gluten-free as a “very important” factor when buying food [3]. The typical gluten-free consumer might surprise you. A 2015 survey revealed that gluten-free food purchases were more common among: Women (23% versus 19% of men) Non-white respondents (31% versus 17% of white respondents) Those with a high school diploma or less (26% versus 17% with some college education) Households with income below $30,000 (24% versus 15% of those earning $75,000+) [3] Perceived vs real benefits of not eating gluten People often choose gluten-free diets based on beliefs rather than science. A 2015 survey revealed that “no reason” (35%) topped the list for picking gluten-free foods. “Healthier option” (26%) and “digestive health” (19%) followed [3]. Weight loss wasn’t a big factor, though most people believe it’s the main benefit [4]. People who eat gluten-free foods often think they’re healthier because they seem like “cleaner” alternatives to regular products [5]. Many say they feel less bloated and have better digestion after cutting out gluten [5]. Research shows that beliefs like “a gluten-reduced diet is healthier” and “gluten-free products are more nutritious than regular ones” often lead people to try gluten-free diets [6]. Notwithstanding that, scientists agree that removing gluten doesn’t improve health if you have no gluten sensitivity [2]. Gluten-free products often have more calories, fat, and sodium. They also contain less vitamin B-12, folate, niacin, vitamin D, iron, zinc, magnesium, calcium, dietary fiber, and protein than regular foods [2]. The Food Scan Genius app is a great way to get help if you’re learning about gluten-free options. It uses AI-powered conversation technology and offers over 35 customizable filters. This difference matters because many processed gluten-free foods pack extra sugar, fat, and additives to make up for missing gluten [5]. Surprising benefits of gluten-free living People without celiac disease have found substantial improvements in their overall wellbeing after switching to a gluten-free diet. These unexpected health benefits are way beyond what most healthcare providers typically discuss with patients. Better digestion even without celiac disease A gluten-free diet can dramatically improve your digestive function even without celiac disease. One of the most immediate effects is reduced bloating and gas – common symptoms that usually improve within weeks [7]. If you have non-celiac gluten sensitivity, removing gluten reduces inflammation in your digestive tract and allows the gut lining to recover [7]. Your bowel movements become more regular after eliminating gluten. People who used to deal with chronic constipation or diarrhea often notice their digestive rhythm returns to normal [7]. A balanced gluten-free diet rich in fiber from fruits, vegetables, and gluten-free whole grains supports healthy digestion [8]. The Food Scan Genius app makes finding truly healthy gluten-free options easier with its 35 customizable filters and AI-powered conversation technology. Unlike other food scanners, it helps you identify products that are both gluten-free and nutritionally balanced. Improved sleep and reduced inflammation So, removing gluten may substantially improve your sleep quality. Research shows that people with celiac disease are nearly twice as likely to struggle with insomnia [9], but eliminating gluten can help restore normal sleep patterns. Gluten and sleep are connected through inflammation. Gluten consumption triggers inflammatory responses in sensitive individuals that disrupt the gut microbiome [10]. This matters because your gut produces 95% of your body’s serotonin – a precursor to melatonin, the sleep hormone [11]. Plus, gluten-related inflammation affects how your body absorbs sleep-essential minerals: Calcium (affects melatonin production) Magnesium (supports relaxation) Potassium (regulates sleep cycles) [10] A 4-6 week gluten elimination diet might reveal whether gluten sensitivity affects your sleep [10]. Boosted mental clarity and mood Going gluten-free benefits extend to mental wellbeing. “Brain fog” – marked by difficulty concentrating, memory problems, and mental fatigue – commonly affects people with gluten sensitivity [12]. Clinical studies have found gluten-free diets substantially improve pooled depressive symptom scores in treated patients. After one year, there was no difference in mean scores between patients and healthy controls [13]. The inflammation from gluten consumption can affect any part of your body, including your brain, and may demonstrate as psychiatric or behavioral
