Gluten is a naturally occurring protein found in cereal grains such as wheat, barley, and rye. In India, wheat is a staple food and is commonly consumed in the form of roti, chapati, paratha, naan, bread, biscuits, pasta, and other bakery products.
Gluten provides elasticity to dough, giving bread and other baked goods their soft texture and helping processed foods maintain their shape. In addition to occurring naturally, gluten is often added to packaged and processed foods to improve texture, consistency, and shelf life.
The human digestive system contains enzymes that help break down proteins, fats, and carbohydrates. However, gluten is a complex protein that is not completely broken down during digestion. In most healthy individuals, this does not cause any health problems.
Whole grains containing gluten provide several essential nutrients, including: Protein, Dietary fibre, B-complex vitamins, Iron, Magnesium, Zinc. For centuries, gluten-containing grains have formed an important part of a balanced diet. Health concerns are generally linked to highly processed foods made from refined wheat flour (maida), which often contain excessive amounts of sugar, salt, unhealthy fats, and preservatives, rather than gluten itself.
Gluten is naturally present in:
Although oats are naturally gluten-free, they may become contaminated during processing if handled alongside wheat, barley, or rye. Individuals with celiac disease should therefore consume only certified gluten-free oats.
Although gluten is safe for most people, some individuals develop medical conditions in which gluten triggers harmful immune or digestive responses. These conditions include celiac disease, non-celiac gluten sensitivity, wheat allergy, and gluten ataxia.
Celiac disease is a lifelong autoimmune disorder in which consuming gluten causes the immune system to mistakenly attack the lining of the small intestine. This immune response gradually damages the tiny finger-like projections called villi, which are responsible for absorbing nutrients from food.
As the villi become damaged, the body's ability to absorb essential vitamins, minerals, and other nutrients decreases, leading to nutritional deficiencies and various health problems.
Currently, there is no cure for celiac disease. The only effective treatment is a strict, lifelong gluten-free diet, which allows the small intestine to heal, restores nutrient absorption, relieves symptoms, and helps individuals maintain a healthy and active life.
If left untreated, celiac disease may lead to serious long-term complications such as osteoporosis, infertility, neurological disorders, and an increased risk of certain intestinal cancers.
Non-Celiac Gluten Sensitivity (NCGS) is a condition in which individuals develop symptoms after consuming gluten despite testing negative for celiac disease and wheat allergy.
Unlike celiac disease, NCGS does not cause autoimmune damage to the small intestine or permanent intestinal injury. However, it can significantly affect an individual's quality of life.
Symptoms usually improve once gluten is removed from the diet. In some individuals, symptoms may actually be related to poorly absorbed carbohydrates called FODMAPs, which are naturally present in wheat and certain other foods.
A wheat allergy is an allergic reaction to proteins found in wheat. Unlike celiac disease, it is not an autoimmune disorder. Symptoms usually appear shortly after consuming wheat.
Gluten ataxia is a rare autoimmune neurological disorder in which the body's immune response to gluten attacks parts of the nervous system, leading to problems with balance, coordination, and movement.
Anyone experiencing persistent digestive symptoms or discomfort after eating gluten-containing foods should consult a qualified healthcare professional.
It is important not to begin a gluten-free diet before medical testing, as this may affect the accuracy of diagnostic results.
If diagnosed with a gluten-related disorder, individuals should take the following proactive steps:
Follow a strict gluten-free diet as advised by their healthcare provider.
Consult a registered dietitian to ensure nutritional adequacy.
Carefully read food labels for hidden sources of gluten.
Avoid cross-contamination during food preparation.
Attend regular medical follow-up appointments to monitor nutritional status and overall health.
Public awareness and early diagnosis play a vital role in improving the quality of life of individuals with gluten-related disorders. Schools, workplaces, restaurants, food manufacturers, and healthcare providers can contribute by offering accurate food labelling, safe gluten-free meal options, and supportive environments.
Greater awareness helps reduce misconceptions and stigma while ensuring that individuals with celiac disease and non-celiac gluten sensitivity can participate safely and confidently in everyday life.
