From the benefits of gluten to the risks of a gluten-free diet, we’ll cover it all. So, whether you’re a gluten lover or a gluten hater, read on to find out who really needs a gluten-free diet.
Understanding Gluten and Gluten-Free Diets
What is gluten?
Gluten is a group of proteins found in grains such as wheat, barley, and rye. It is responsible for the elasticity and texture of dough, giving bread its chewy texture. Gluten is composed of two main proteins: glutenin and gliadin. Gliadin is the component that triggers an immune response in people with celiac disease.
In the body, gluten is broken down into smaller peptides during digestion, which are then absorbed into the bloodstream. These peptides can trigger an immune response in people with celiac disease, leading to inflammation and damage to the small intestine.
Gluten is found in many foods, including bread, pasta, cereals, and baked goods. It is also often used as a stabilizing or thickening agent in processed foods, such as soups and salad dressings.
For people with celiac disease, consuming gluten can cause a range of symptoms, including abdominal pain, diarrhea, and fatigue. In addition, long-term exposure to gluten can lead to nutrient deficiencies and other health problems. For this reason, people with celiac disease are required to follow a strict gluten-free diet to manage their condition.
Who can benefit from a gluten-free diet?
A gluten-free diet is beneficial for individuals who have certain medical conditions that affect their ability to digest gluten, a protein found in wheat, barley, and rye. The following are the three main conditions that can benefit from a gluten-free diet:
- Celiac Disease
Celiac disease is an autoimmune disorder that affects about 1% of the global population. When individuals with celiac disease consume gluten, their immune system reacts by damaging the lining of the small intestine, impairing nutrient absorption. Common symptoms include diarrhea, abdominal pain, and fatigue. The only treatment for celiac disease is a lifelong gluten-free diet. - Non-Celiac Gluten Sensitivity (NCGS)
Non-celiac gluten sensitivity is a condition where individuals experience gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten-containing foods, in the absence of celiac disease or wheat allergy. The exact cause of NCGS is still unknown, and there is no specific test to diagnose it. However, eliminating gluten from the diet can help alleviate symptoms in some individuals. - Wheat Allergy
Wheat allergy is an immune response to proteins in wheat, and it is different from gluten sensitivity or intolerance. Symptoms of wheat allergy can range from mild (itching and hives) to severe (anaphylaxis). Individuals with wheat allergy must avoid all sources of wheat, including gluten-containing foods.
How to maintain a gluten-free diet
Grocery shopping tips
When it comes to maintaining a gluten-free diet, grocery shopping can be a challenge. However, with a little bit of planning and knowledge, it can be done easily. Here are some tips to help you navigate the grocery store aisles:
- Read labels carefully: Make sure to read the labels of all the products you purchase to ensure that they do not contain any gluten-containing ingredients. Pay close attention to ingredients such as wheat, barley, and rye, which are common sources of gluten.
- Look for gluten-free certifications: Many products these days are labeled as gluten-free. However, not all of them are safe for people with celiac disease or gluten sensitivity. Look for products that have been certified as gluten-free by reputable organizations such as the Gluten-Free Certification Organization (GFCO) or the Celiac Sprue Association (CSA).
- Check the ingredients list: Even if a product is labeled as gluten-free, it may still contain ingredients that are derived from gluten-containing grains. For example, some soy sauces may contain wheat-based maltodextrin. Make sure to check the ingredients list for any potential sources of gluten.
Cooking and dining out strategies
Cooking at home is the best way to ensure that you are consuming a gluten-free diet. However, dining out can be a challenge, especially if you are not familiar with the ingredients used in the dishes. Here are some strategies to help you navigate dining out:
- Research ahead of time: Before you go out to eat, research the restaurant’s menu to identify any gluten-containing ingredients. You can also call ahead and ask the restaurant about their gluten-free options.
- Speak with the chef: If you are unsure about a dish or ingredient, speak with the chef or server to ask about potential sources of gluten. They may be able to suggest a gluten-free option or modify a dish to make it safe for you to eat.
- Carry gluten-free foods with you: If you are unsure about the safety of a dish or if you are in an area where gluten-free options are limited, it may be helpful to carry gluten-free foods with you. This can include snacks such as gluten-free crackers or energy bars, or even a full meal that you can eat if necessary.
By following these tips, you can maintain a gluten-free diet and enjoy a variety of delicious and healthy foods.

Who Should Consider a Gluten-Free Diet?
Celiac disease
Celiac disease is an autoimmune disorder that affects the small intestine. It is caused by a reaction to gluten, a protein found in wheat, barley, and rye. When a person with celiac disease consumes gluten, their immune system responds by attacking the lining of the small intestine, causing damage and impairing nutrient absorption.
Symptoms and diagnosis
Symptoms of celiac disease can vary widely and may include:
- Abdominal pain and bloating
- Diarrhea
- Fatigue
- Weight loss
- Skin rashes
- Bone or joint pain
- Brain fog or behavioral changes
Diagnosis of celiac disease typically involves a combination of blood tests and biopsy of the small intestine. A healthcare provider may also ask about a person’s symptoms and medical history.
Treatment and management
The only way to manage celiac disease is to follow a strict gluten-free diet. This means avoiding all foods and products containing gluten, including wheat, barley, and rye. It is important to work with a healthcare provider and a registered dietitian to develop a comprehensive plan for managing the disease.
Adherence to a gluten-free diet can lead to improved symptoms and quality of life for people with celiac disease. It is also important to be aware of hidden sources of gluten, such as modified food starch and maltodextrin, which may be found in processed foods. Regular follow-up with a healthcare provider is necessary to monitor the effectiveness of the gluten-free diet and to detect any complications.
Non-celiac gluten sensitivity
Non-celiac gluten sensitivity (NCGS) is a condition in which individuals experience gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten-containing foods, despite having no celiac disease or wheat allergy. It is important to note that NCGS is not an autoimmune disorder like celiac disease, and the exact cause of NCGS is still not fully understood.
- Symptoms and diagnosis
- Common symptoms of NCGS include abdominal pain, bloating, diarrhea, constipation, and fatigue. Other extra-intestinal symptoms such as headache, joint pain, and dermatitis may also occur.
- The diagnosis of NCGS is based on the patient’s symptoms and response to a gluten-free diet. There is currently no definitive test for NCGS, and the diagnosis is considered a “diagnosis of exclusion” after ruling out other possible causes of the symptoms.
- Treatment and management
- The mainstay of treatment for NCGS is a gluten-free diet. This involves avoiding all sources of gluten, including wheat, barley, and rye. Oats are generally considered safe for individuals with NCGS, but may need to be avoided if there is cross-contamination during processing.
- Some individuals with NCGS may also benefit from probiotics or prebiotics to improve gut health and reduce symptoms.
- It is important to note that a gluten-free diet should only be adopted under the guidance of a healthcare professional, as it may lead to nutrient deficiencies if not planned properly.
Wheat allergy
Wheat allergy is a type of food allergy that occurs when the body’s immune system reacts to proteins in wheat. It is important to note that a wheat allergy is different from a gluten intolerance or celiac disease, which are related to the immune system’s reaction to gluten rather than to wheat proteins specifically.
Symptoms and diagnosis
Symptoms of a wheat allergy can range from mild to severe and may include:
- Skin rash or hives
- Itching or swelling of the mouth or throat
- Abdominal pain or cramps
- Diarrhea or vomiting
- Fatigue or irritability
- In severe cases, anaphylaxis (a life-threatening allergic reaction)
Diagnosis of a wheat allergy involves a detailed medical history, physical examination, and skin prick tests or blood tests to determine the presence of allergy-causing antibodies.
Treatment and management
The best way to manage a wheat allergy is to avoid foods that contain wheat. This means avoiding baked goods, cereals, pasta, and other products made with wheat flour. In some cases, a healthcare provider may recommend an elimination diet to determine if a wheat allergy is present.
In the event of a severe allergic reaction, emergency treatment such as epinephrine (adrenaline) may be necessary. It is important for individuals with a wheat allergy to carry an epinephrine injector (e.g. EpiPen) at all times and to seek medical attention immediately in the event of a severe reaction.
In conclusion, individuals with a wheat allergy should consider a gluten-free diet to avoid triggering symptoms and reducing the risk of a severe allergic reaction. It is important to work with a healthcare provider to develop a personalized treatment plan and to carefully read food labels to avoid hidden sources of wheat.
Other medical conditions related to gluten
Gluten is a protein found in wheat, barley, and rye, and for many people, it is harmless. However, there are some medical conditions that are related to gluten and require a gluten-free diet. In this section, we will discuss some of these conditions.
- Inflammatory bowel disease (IBD)
Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the intestine that includes Crohn’s disease and ulcerative colitis. Some people with IBD may benefit from a gluten-free diet, although the exact mechanism is not fully understood. A gluten-free diet may help reduce inflammation and improve symptoms in some people with IBD. - Irritable bowel syndrome (IBS)
Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that affects the large intestine. While the exact cause of IBS is unknown, some people with IBS may experience symptom improvement with a low FODMAP diet, which often includes avoiding gluten-containing foods. However, not all people with IBS need to follow a gluten-free diet. - Autism spectrum disorder (ASD)
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects communication and behavior. There is limited evidence to support the use of a gluten-free diet for people with ASD. Some studies have suggested that a gluten-free diet may improve gastrointestinal symptoms and behavior in some people with ASD, but more research is needed to confirm these findings.
It is important to note that a gluten-free diet should only be considered under the guidance of a healthcare professional, as eliminating gluten without medical supervision can lead to nutrient deficiencies and other health problems.
