You may have noticed that gluten-free foods and products are everywhere these days, from grocery stores to restaurants to online shops. Many people are choosing to follow gluten-free diets, either for medical reasons or for personal preferences. Some claim that gluten-free diets are healthier, or that they can help with weight loss, energy levels, or skin problems. But is there any scientific evidence to back up these claims? And are there any risks or drawbacks of going gluten-free? In this article, we will consult registered dietitians and experts to find out.
- What is gluten and who should avoid it?
- Gluten is a protein that is found in certain grains, such as wheat, barley, rye, and some other grains. It gives dough its elasticity and helps baked goods rise and hold their shape. Gluten is also used as an additive in some processed foods, such as sauces, soups, cereals, and snacks, to improve their texture, flavor, and shelf life.
- Some people need to avoid gluten because they have a medical condition that makes them allergic or intolerant to it. These conditions include:
- Celiac disease: This is an autoimmune disorder that affects the small intestine. When people with celiac disease eat gluten, their immune system attacks the lining of their intestine, causing inflammation, damage, and malabsorption of nutrients. This can lead to symptoms such as diarrhea, bloating, abdominal pain, weight loss, anemia, and osteoporosis. Celiac disease can also increase the risk of other complications, such as infertility, neurological disorders, and cancer. The only treatment for celiac disease is a strict gluten-free diet for life1
- Non-celiac gluten sensitivity: This is a condition that causes similar symptoms as celiac disease, but without the intestinal damage or the autoimmune response. People with non-celiac gluten sensitivity may experience gastrointestinal discomfort, headaches, fatigue, joint pain, and skin rashes after eating gluten. The exact cause and mechanism of non-celiac gluten sensitivity are not well understood, but it is believed to involve the immune system and the nervous system. The treatment for non-celiac gluten sensitivity is a gluten-free diet, but some people may be able to tolerate small amounts of gluten2
- Wheat allergy: This is a type of food allergy that occurs when the immune system reacts to wheat proteins, including gluten. People with wheat allergy may experience symptoms such as itching, swelling, hives, sneezing, wheezing, and anaphylaxis after eating wheat or wheat products. Wheat allergy is different from celiac disease and non-celiac gluten sensitivity, as it involves a different part of the immune system and can be triggered by other wheat proteins besides gluten. The treatment for wheat allergy is avoiding wheat and wheat products, and carrying an epinephrine auto-injector in case of a severe reaction3
- Some people choose to avoid gluten for other reasons, such as personal preference, weight loss, or general health. However, there is no scientific evidence that gluten-free diets are healthier or more effective for these purposes than regular diets. In fact, gluten-free diets may have some drawbacks, such as being more expensive, less convenient, and less nutritious than regular diets4
- What are the advantages of gluten-free diets for people who need them?
- For people who have celiac disease, non-celiac gluten sensitivity, or wheat allergy, gluten-free diets are essential for managing their symptoms and preventing complications. Gluten-free diets can help them:
- Reduce inflammation and heal their intestine (in the case of celiac disease)
- Improve their digestion and absorption of nutrients
- Relieve their gastrointestinal discomfort and pain
- Prevent or reverse their anemia and osteoporosis (in the case of celiac disease)
- Enhance their energy and mood
- Lower their risk of other autoimmune disorders, neurological disorders, and cancer (in the case of celiac disease)
- Avoid life-threatening allergic reactions (in the case of wheat allergy)
- For people who have celiac disease, non-celiac gluten sensitivity, or wheat allergy, gluten-free diets can also improve their quality of life and well-being, as they can enjoy their food without fear or discomfort, and participate in social and cultural activities without restrictions or limitations.

- What are the disadvantages of gluten-free diets for people who do not need them?
- For people who do not have a medical reason to avoid gluten, gluten-free diets may not have any significant benefits, and may even have some negative consequences, such as:
- Higher cost and lower availability: Gluten-free foods and products are often more expensive and less accessible than regular foods and products, as they require special ingredients, processing, and labeling. Gluten-free diets may also limit the choices and options of people who follow them, especially when eating out or traveling.
- Lower nutritional quality and diversity: Gluten-free foods and products are often lower in fiber, iron, zinc, folate, calcium, vitamin B12, and other nutrients than regular foods and products, as they are made with refined flours and starches, and lack the fortification and enrichment of wheat products. Gluten-free diets may also reduce the intake and variety of whole grains, fruits, vegetables, and legumes, which are rich sources of antioxidants, phytochemicals, and prebiotics that are beneficial for health.
- Higher calorie and fat content: Gluten-free foods and products are often higher in calories and fat than regular foods and products, as they contain more sugar, oil, and additives to improve their taste, texture, and shelf life. Gluten-free diets may also increase the consumption of processed foods, snacks, and desserts, which are high in calories, fat, sugar, and salt, and low in nutrients and fiber. These factors may contribute to weight gain, obesity, and chronic diseases, such as diabetes, heart disease, and cancer.
- For people who do not have a medical reason to avoid gluten, gluten-free diets may not have any significant benefits, and may even have some negative consequences, such as:
Conclusion
Gluten-free diets are medically necessary for people who have celiac disease, non-celiac gluten sensitivity, or wheat allergy, as they can help them manage their symptoms and prevent complications. Gluten-free diets can also improve their quality of life and well-being, as they can enjoy their food without fear or discomfort, and participate in social and cultural activities without restrictions or limitations.
However, gluten-free diets are not healthier or more effective than regular diets for people who do not have a medical reason to avoid gluten. In fact, gluten-free diets may have some drawbacks, such as being more expensive, less convenient, and less nutritious than regular diets. Gluten-free diets may also increase the risk of weight gain, obesity, and chronic diseases, such as diabetes, heart disease, and cancer.
Therefore, before deciding to follow a gluten-free diet, it is important to consult a doctor and a registered dietitian, who can diagnose the condition, prescribe the treatment, and provide the guidance and support.
