Gluten sensitivity: Unraveling the mystery and its impact on the food industry
The rise of gluten sensitivity and its surprising prevalence
Gluten sensitivity is a growing concern, affecting a significant portion of the global population. With one in ten people worldwide reporting symptoms, it's more common than you might think. And here's where it gets interesting: women are almost twice as likely as men to experience these symptoms.
The UK and Saudi Arabia have even higher rates, with 23% and 36% of their populations respectively reporting gluten sensitivity. But here's the catch: despite this, 40% of those who self-report these symptoms still follow gluten-free diets, even though the exact cause remains unclear.
What's really behind gluten sensitivity?
Non-coeliac gluten sensitivity is a condition that causes gastrointestinal and extraintestinal symptoms like bloating, abdominal pain, and diarrhoea, but without the presence of coeliac disease. It's mostly self-reported, and there are no clear biomarkers to diagnose it.
The gluten-free market has boomed, in part due to the public's awareness of gluten sensitivity and the desire to manage it. However, a recent study suggests that gluten sensitivity may not be solely linked to gluten itself. The renowned medical journal, The Lancet, reviewed a wide range of studies and found that fermentable carbohydrates, or FODMAPs, might be a bigger culprit for those with self-reported gluten sensitivity.
FODMAPs, commonly found in vegetables, fruits, legumes, and cereals, can cause more discomfort for those with gluten sensitivity than gluten. Interestingly, cutting out FODMAPs often relieves symptoms, even when gluten is reintroduced. This review also highlights the significant interaction between gluten sensitivity and the gut-brain axis, further complicating the picture.
Additionally, there's often no difference in symptoms between those consuming a placebo and those consuming gluten. This leads researchers to believe that the condition might be influenced by the consumer's belief about gluten, rather than gluten itself. This phenomenon is known as the 'nocebo' effect.
The impact on the industry
With the source of gluten sensitivity now in question, the gluten-free market could be affected. Considering the market's size and the relatively small coeliac population, demand for gluten-free products is likely driven by those experiencing non-coeliac gluten sensitivity. However, with studies suggesting that giving up gluten may not always relieve symptoms, it's clear that gluten-free products aren't meeting the needs of all consumers.
But it's not all doom and gloom. Many consumers choose gluten-free products for general health reasons, not just for managing gluten sensitivity. As more research emerges, changing demand could reshape the free-from market. Will gluten-sensitive consumers eventually return to the conventional bread aisle? Only time will tell, but one thing's for sure: the gluten-free market is here to stay, and it's an exciting space to watch.
