gliGluten-free diets have become increasingly popular among millennials and Gen Z. Fitness influencers promote them on social media, while others dismiss the trend, leaving many people confused about this common food ingredient. So, what exactly is gluten? And does following a gluten-free diet offer any real advantage?

All about Gluten

Gluten is a protein found in wheat, rye, spelt, barley and other grains. It forms the dough in wheat flour and has become a commodity in its own right over the past five decades. Large-scale industrial processes that separate wheat starch from gluten, along with controlled drying methods that preserve its functional properties, have helped drive its commercial use. Wheat remains the most common gluten-containing grain.

Gluten contains two primary proteins: glutenin and gliadin. Food manufacturers increasingly use gluten because it offers a wider range of functional properties at a lower cost than alternatives such as milk and soy proteins.

When heated, gluten forms an elastic network that stretches and traps gas. This helps rotis, breads, pasta, pastries and similar products rise properly while retaining moisture. Gluten also gives these foods their characteristic chewiness and texture. Kneading dough naturally promotes gluten formation, while manufacturers may add extra gluten to flour to achieve specific results. Added gluten can increase the chewiness, volume and structural strength of finished products.

Food manufacturers also use gluten in vegan and imitation meat products to create a meat-like texture. It can act as a stabilising agent in products such as beer, soy sauce, ice cream and ketchup. Manufacturers sometimes add it to pet food to increase its protein content. Gluten can also occur in certain cosmetics, hair products and dermatological preparations.

Most people tolerate gluten without problems. However, it can cause difficulties in people with gluten intolerance or sensitivity, particularly to the gliadin component. Conditions associated with gluten or wheat include celiac disease, non-celiac gluten sensitivity and wheat allergy, among others.

Is a Gluten-free Diet a Necessity?

Celiac disease, which is the most severe form of gluten intolerance, is treated mostly through a gluten-free diet. This is an autoimmune disorder that affects the gut wall, which can lead to nutrient deficiencies, anaemia, severe digestive problems, and a higher risk of a variety of diseases. Nonceliac gluten sensitivity is recognised as an issue in several nations. However, because this is a new field of inquiry, researchers are still learning about the disorder, its risk factors, and how widespread it is. Celiac disease and gluten sensitivity can only be treated with a rigorous gluten-free diet.

Many others who do not have this condition are also going gluten-free for supposed health benefits. Without celiac disease or a nonceliac gluten sensitivity, there is minimal scientific evidence that a gluten-free diet is beneficial to one’s health. People who eliminate gluten products from their diet and do not appropriately replace them with other carbs may be at risk of deficiency in fibre, calories, and B vitamins. Gluten-free does not always imply that a product is healthy, and gluten-free junk food is still junk food.

Why are People going Gluten-Free?

Many people in the health and wellness sector believe that everyone, whether gluten sensitive or not, should follow a gluten-free diet. Millions of people have given up gluten in the hopes of losing weight, improving their mood, and becoming healthier as a result of this. Still, one might wonder if these practices are scientifically sound. There are a number of reasons as to why people are opting to go completely gluten-free. Some of them include-

• The perception that a gluten-free diet is healthier and can help with non-specific gastrointestinal issues is gaining traction.
• An increasing number of individuals are diagnosing themselves with gluten sensitivity, and they’ve observed that reducing gluten from their diet has improved their gastrointestinal health.
• Gluten-free products have become more easily available in recent years.

Is Gluten a Blessing in Disguise?

Gluten functions as a litmus test, revealing signs of inflammation and a weakened gut microbiome. These preconditions exist before gluten is introduced, but they become worse when gluten is introduced. As a result, many people find that switching from a conventional diet to a high-nutrient, gluten-free diet makes them feel better. Therefore, gluten in a way helps us understand the underlying mechanisms of health and disease.

There is minimal evidence that following a gluten-free diet has health benefits for individuals who do not have celiac disease or non-celiac gluten sensitivity. When a person eliminates gluten-rich foods from their diet, they must acquire enough nutrients from other foods. Therefore, there is a divide when it comes to whether gluten is good for us or not, depending on each person’s body, health and the ability to tolerate it, rather than blindly following the herd.
