Life without gluten: how to adapt to a new diet with celiac disease?

This article will comprehensively cover all aspects of living without gluten, including the challenges faced by those with celiac disease, psychological adjustments, social aspects, and key recommendations to ensure that a gluten-free diet is effective.

WHAT IS CELIAC DISEASE?

Celiac disease is an autoimmune disorder in which the body's immune system mistakenly attacks the lining of the small intestine when gluten—a protein found in wheat, rye, and barley—is consumed. This results in inflammation, damage to the intestinal lining, and can cause malabsorption—the inability to properly absorb nutrients, vitamins, and minerals. These consequences lead to various health problems, ranging from mild digestive issues to serious conditions like anemia, osteoporosis, and even certain types of cancer.

Primary symptoms

Celiac disease can manifest through a wide range of symptoms, which vary greatly among individuals, and include:

• Diarrhea, abdominal pain, and bloating.
• Fatigue, weakness, and anemia.
• Weight loss or poor weight gain (especially in children).
• Osteoporosis due to poor calcium and vitamin D absorption.
• Skin rashes, most commonly known as dermatitis herpetiformis.
• Psychological symptoms such as irritability, depression, and difficulty concentrating.

Diagnosing celiac disease is often challenging because its symptoms can resemble other conditions, such as irritable bowel syndrome (IBS), chronic fatigue syndrome, or various autoimmune diseases. Diagnosis is usually made through blood tests and a biopsy of the small intestine to detect antibodies against gluten proteins and assess damage to the intestinal lining.

THE GLUTEN-FREE DIET: WHAT TO ELIMINATE FROM THE MENU?

A gluten-free diet is essential for everyone with celiac disease. Gluten is a protein naturally found in wheat, barley, and rye, so the first step is to completely remove these grains and their products from the diet.

Grains and foods containing gluten

• Wheat: This includes not only regular wheat but also its various forms such as spelt, kamut, triticale, and other hybrid grains.
• Rye: Commonly used in baked goods such as bread and rye flour.
• Barley: Frequently used in beer production, malt, and certain flavorings and additives.
• Wheat starches and hydrolyzed vegetable proteins: These can be hidden in various processed foods, making it crucial to read labels carefully.

Hidden sources of gluten

Gluten can be found not only in grains but also in various processed foods that may be contaminated or that contain added wheat-based products:

• Sauces and seasonings, such as soy sauce, which often contain wheat.
• Some candies and confectionery additives.
• Medications and supplements may be made with wheat starches.
• Therefore, it is vital to read food labels carefully and choose products that are clearly labeled as "gluten-free."

GLUTEN-FREE FOODS

Fortunately, there are many naturally gluten-free foods that are safe for those with celiac disease and can help maintain a balanced diet while avoiding nutrient deficiencies.

Naturally gluten-free foods

• Fruits and vegetables: A natural source of vitamins, minerals, and fiber.
• Meat, fish, and poultry: Unprocessed meat is naturally gluten-free.
• Dairy products: Most dairy products, such as cheese, yogurt, and milk, are safe, though it's important to check processed versions.
• Legumes: Beans, lentils, and chickpeas are not only gluten-free but also an excellent source of protein and fiber.
• Buckwheat, quinoa, rice, and corn: These grains are safe and can be used as alternatives to wheat.

Gluten-Free flours

Living without gluten doesn’t mean you have to give up baking. There are plenty of alternative flours available:

• Rice flour: Mild in flavor, perfect for cakes and cookies.
• Buckwheat flour: Darker and more robust in flavor, often used in pancakes and bread.
• Corn flour: Used in both baked goods and as a thickener for puddings and stews.
• Coconut and almond flour: These nut-based flours are nutritious and ideal for desserts.

CROSS-CONTAMINATION: WHAT IT IS AND HOW TO AVOID IT?

Cross-contamination is a serious issue for people with celiac disease, as even the smallest amount of gluten can trigger health problems. Cross-contamination occurs when gluten-free food comes into contact with gluten-containing products, such as sharing the same table or kitchen utensils. Here are some recommendations for minimizing the risk of cross-contamination:

At home

Use separate kitchen tools (e.g., knives, cutting boards, pans) for gluten-free foods.

Clean surfaces thoroughly, especially when using shared workspaces.

Toast gluten-free bread in a separate toaster or use special baking parchment.

Eating Out

Always inform restaurant staff about your dietary requirements. Be sure they understand that even a small amount of gluten can pose a health risk.

Choose restaurants that offer special gluten-free diets or those that have gluten-free menus.

When traveling, bring gluten-free snacks with you in case you can't find safe food options.

ENSURING A BALANCED DIET WHILE FOLLOWING A GLUTEN-FREE DIET?

When people switch to a gluten-free diet, they often face nutritional deficiencies, as eliminating gluten-containing products can limit food variety and reduce nutrient intake. Also, gluten-free processed products tend to be less nutritious because they may lack fiber, iron, and B vitamins.

Key nutrients to ensure in your diet

• Fiber: Gluten-free products often contain less fiber, so it's important to include plenty of fruits, vegetables, bran, legumes, and whole grain alternatives (e.g., buckwheat, quinoa).
• Vitamins and minerals: Wheat products are a good source of B vitamins, iron, and zinc, so it's essential to incorporate these nutrients through eggs, meat, dairy products, and legumes.
• Calcium and vitamin D: People with celiac disease often struggle with calcium and vitamin D absorption, so it's necessary to consume enough dairy products or replace them with plant-based alternatives fortified with calcium and vitamin D.
• Omega-3 fatty acids: These fatty acids are important for brain function and heart health. Include fatty fish (e.g., salmon, sardines) and nuts in your diet.

PSYCHOLOGICAL AND SOCIAL ASPECTS OF LIVING WITH CELIAC DISEASE

Adapting to a gluten-free lifestyle can lead to psychological challenges. Changing habits, learning to avoid gluten, and coping with social changes can be emotionally exhausting.

PSYCHOLOGICAL CHALLENGES

Living with celiac disease often brings emotional discomfort due to constant restrictions, fear of accidental gluten exposure, and social isolation. Some people may experience anxiety or depression over maintaining the diet and the possibility of falling ill unexpectedly.

Psychological support, whether individual or through groups, can help manage these feelings. Therapy or counseling can provide tools to cope with stress and anxiety.

SOCIAL ASPECTS

Living with celiac disease can affect social life. Eating out, attending parties, or traveling can become challenging due to limited food choices. It's important to learn how to communicate your needs effectively. Don't be afraid to inform friends, family, or colleagues about your condition and necessary dietary restrictions.

Community and support groups can also be beneficial. They provide an opportunity to share experiences, advice, and resources with others facing the same challenges.

GLUTEN-FREE DIET TRENDS AND MISCONCEPTIONS

In recent years, the gluten-free diet has gained popularity not only among those with celiac disease but also among people seeking a healthier lifestyle. However, this dietary approach is not always beneficial for those without celiac disease or gluten intolerance. Some people choose gluten-free products for weight loss or general health improvement, even though there is no scientific evidence that gluten avoidance benefits people without celiac disease.

It’s important to understand that a gluten-free diet is medically necessary only for those diagnosed with celiac disease or confirmed gluten intolerance. For others, it may not only be unnecessary but could also limit the intake of important nutrients.

Living gluten-free with celiac disease requires constant attention to food, product ingredients, and social situations. While it may be a challenging and sometimes difficult process, by strictly following the diet and acquiring the necessary knowledge, people with celiac disease can lead a full life without gluten and avoid long-term health complications. The expanding gluten-free product market and increasing public awareness help ensure that managing this disease becomes easier.
