Understanding Gluten: Its Effects, Misleading Labels, and the Facts You Need to Know
Gluten, a protein found in certain grains, has become a hot topic in the food world. You might have seen "gluten-free" labels on many products, including ones like salt that don't have gluten in the first place. Let’s break down what gluten is, where it's found, how it affects some people, and why there's confusion due to how food companies label their products.
What Exactly is Gluten?
Gluten is a protein found in grains like wheat, barley, and rye. It helps bread rise and gives it a chewy texture. However, it's not found in grains like corn, rice, and quinoa.
Where You Might Find Gluten
Gluten is common in bread, pasta, and cereals. It's also often in less obvious foods like soups, sauces, and even some salad dressings, because it's used as a thickener.
Foods That Can't Have Gluten, But Get the Label Anyway
You'll often see "gluten-free" on things that naturally don't have gluten, such as rice, fruits, vegetables, and most dairy products. Even products like bottled water and salt, which could never contain gluten, sometimes have this label. It's a marketing strategy that can be misleading.
Gluten's Impact on Health
For most people, gluten is perfectly fine to eat. But for those with celiac disease, eating gluten damages their small intestine. Symptoms include stomach pain, bloating, and tiredness. Another condition, called non-celiac gluten sensitivity, causes similar, but usually less severe, symptoms.
Numbers to Know
About 1% of people worldwide have celiac disease. That's about 75 million people.
Non-celiac gluten sensitivity may affect between 0.5% to 13% of people.
Many people choose gluten-free diets even without a medical need.
The Truth Behind "Gluten-Free" Labels
Some food companies use the "gluten-free" label as a selling point, even on products like eggs or cheese that never had gluten. This can make it harder to understand what gluten-free really means and may even make light of serious conditions like celiac disease.
Conclusion
Knowing about gluten and its real effects is key to making smart choices about what you eat. The "gluten-free" label is important for those who need it but can be confusing when used on products that naturally don't contain gluten. Being aware and informed is the best way to navigate this.
