Understanding gluten intolerance

Gluten intolerance is a condition that causes various symptoms, such as digestive discomfort, fatigue and mood swings, after consuming foods containing gluten. Gluten is a protein found in wheat, rye and barley, making it a common ingredient in many everyday foods. Although gluten intolerance shares some symptoms with celiac disease and wheat allergy, these conditions are different from each other.

Celiac disease, also known as the most severe form of gluten intolerance, is an autoimmune disease that results in inflammation and damage to the digestive system when gluten is consumed. Non-celiac gluten sensitivity (NCGS), on the other hand, is a milder form of gluten intolerance that still causes discomfort and widespread symptoms.

Wheat allergy is a distinct condition in which the immune system reacts negatively to specific wheat proteins, leading to symptoms such as itching, swelling and breathing difficulties.

Celiac disease vs. Non-Celiac Gluten Sensitivity

Celiac disease affects approximately 1% of the population and has long-term health implications if left undiagnosed. When gluten is consumed, the immune system in individuals with celiac disease mistakenly attacks the digestive system, leading to intestinal damage and malabsorption of nutrients. Symptoms of celiac disease can include diarrhea, constipation, unintentional weight loss, fatigue, and mood changes such as depression and anxiety.

Non-celiac gluten sensitivity (NCGS), on the other hand, is not an autoimmune disease, and its symptoms are generally milder than those of celiac disease. Individuals with NCGS may experience bloating and abdominal discomfort after consuming gluten, but they do not suffer the same level of intestinal damage as those with celiac disease.

Despite these differences, both celiac disease and NCGS require a gluten-free diet to manage symptoms and improve overall health.

Wheat Allergy: Another Gluten-Related Condition

Wheat allergy is another gluten-related condition that occurs when the immune system overreacts to specific wheat proteins. This exaggerated immune response can lead to symptoms such as itching, swelling and breathing difficulties, which differ from the digestive symptoms often experienced with gluten intolerance. Wheat allergy is more common in children than adults, but can affect people of all ages.

In severe cases, wheat allergy can cause anaphylaxis, which is a life-threatening allergic reaction characterized by symptoms such as swelling, hives, nausea, vomiting and breathing difficulties. If anaphylaxis occurs, immediate treatment with epinephrine is necessary to counteract the reaction and prevent further complications.

Understanding the differences between wheat allergy, celiac disease and non-celiac gluten sensitivity is essential for proper diagnosis and management of these conditions.

Common Symptoms of Gluten Intolerance

The symptoms of gluten intolerance can be diverse and often overlap with those of other conditions, making diagnosis challenging. Common symptoms include digestive discomfort (such as diarrhea, constipation, bloating, and abdominal pain), fatigue, and mood swings such as depression and anxiety. Experiencing symptoms after eating foods containing gluten is common. This is commonly known as gluten intolerance.

It is important to note that gluten intolerance may also be linked to an increased risk of neurological and psychiatric diseases, such as dementia and Alzheimer's. Additionally, gluten intolerance is associated with autoimmune diseases due to its ability to cause autoimmune reactions and increased levels of inflammation.

Recognizing these common symptoms is crucial for early diagnosis and effective management of gluten intolerance.

Digestive discomfort

Digestive discomfort is one of the most common symptoms of gluten intolerance, with individuals often experiencing diarrhea, constipation, bloating and abdominal pain. These problems can be attributed to the body's immune response caused by consuming an allergen such as wheat.

Bloating, in particular, is characterized by a feeling of fullness in the stomach that is prolonged and uncomfortable, usually accompanied by a build-up of gas. Identifying these digestive symptoms as possible signs of gluten intolerance can help individuals seek appropriate testing and treatment to alleviate their discomfort.

Fatigue and Brainfog

Fatigue is another common symptom of gluten intolerance, with individuals often feeling tired and exhausted, especially after consuming foods containing gluten. This exhaustion can hinder daily activities and affect overall quality of life.

Brain fog, a feeling of not being able to think clearly, is also associated with gluten intolerance. A 2020 study revealed that 48% of participants experienced brain fog, highlighting the prevalence of this symptom among individuals with non-celiac gluten sensitivity. Recognizing fatigue and brain fog as possible indicators of gluten intolerance can help people focus on a proper diagnosis and learn to manage it better.

Mood Changes and Mental Health

Gluten intolerance can also have a significant impact on mental health, with depression and anxiety being common symptoms. People with digestive problems may be more likely to experience both anxiety and depression than people without underlying conditions.

Additionally, gluten intolerance has been linked to autoimmune thyroid disease, which can manifest as anxiety, depression, fatigue and other symptoms that affect overall quality of life. Being aware of the possible psychological effects of gluten intolerance can help people seek appropriate care and support to improve their mental wellbeing.

Additional Signs of Gluten Intolerance

In addition to the common symptoms mentioned earlier, gluten intolerance can also cause skin reactions and rashes, joint and muscle pain, and nutritional deficiencies. These additional signs can provide further clues to the presence of gluten intolerance and aid in diagnosis and treatment.

It is important to note that some of these symptoms may also indicate other conditions, such as celiac disease or wheat allergy, which emphasizes the importance of proper medical testing and evaluation to determine the underlying cause of these problems. Identifying these additional signs of gluten intolerance can help people seek appropriate care and treatment to relieve their symptoms.

Skin Reactions and Rashes

Skin reactions and rashes can indicate gluten intolerance, with conditions such as eczema, psoriasis, hives and dermatitis herpetiformis often associated. Symptoms of a gluten-induced rash may include red, raised skin lesions or blisters, sores that appear like hives, and lesions that occur in clusters.

In the case of wheat allergies, hives are a common rash. This rash is characterized by itching, redness and inflammation. Recognizing these skin reactions and rashes as possible signs of gluten intolerance can help people seek appropriate testing and treatment to alleviate their discomfort.

Joint and muscle pain

Joint and muscle pain can also indicate gluten intolerance, with people often experiencing discomfort in their joints and muscles. This pain can be widespread and affect different parts of the body, further complicating diagnosis and management.

Understanding the connection between gluten intolerance and joint or muscle pain can help people seek appropriate care and treatment to relieve their pain and improve their overall well-being.

Nutritional deficiencies

Nutritional deficiencies can also indicate gluten intolerance, with deficiencies in iron, calcium, folic acid and vitamin B12 commonly observed. In particular, celiac disease can impair nutrient absorption, leading to reduced iron absorption and iron deficiency anemia.

Identifying nutritional deficiencies as possible signs of gluten intolerance can help people seek appropriate care and treatment to address these deficiencies and improve their overall health and well-being.

Diagnosis of Gluten Intolerance

The diagnosis of gluten intolerance involves a combination of medical tests and nutritional assessments to determine the presence of celiac disease, wheat allergy, or non-celiac gluten sensitivity. Medical testing for celiac disease and wheat allergy can help rule out these conditions, while an elimination diet can help identify food intolerances and confirm a diagnosis of gluten intolerance.

Proper diagnosis is essential for effective management of gluten intolerance because it allows people to adopt the necessary diet and lifestyle changes to alleviate their symptoms and improve their overall health.

Medical Tests for Celiac Disease and Wheat Allergy

Medical tests for celiac disease include serology tests and intestinal biopsies, which can detect signs of celiac disease in a blood sample and assess the presence of certain antibodies associated with the condition. These tests are essential for distinguishing celiac disease from non-celiac gluten sensitivity and wheat allergy, as they can help determine the severity of a person's gluten intolerance and direct appropriate treatment.

In the case of wheat allergy, medical tests may include skin prick tests or blood tests to detect specific antibodies related to an allergic reaction to wheat proteins. Performing these tests can help healthcare providers accurately diagnose gluten intolerance and recommend the most effective course of treatment.

The Role of Elimination Diets

An elimination diet is a nutritional approach that involves temporarily excluding certain foods, such as gluten, from one's diet to determine possible food sensitivities. This process can help determine if gluten is the cause of a person's symptoms and confirm a diagnosis of gluten intolerance.

During an elimination diet, it is essential to eliminate only one variable at a time, such as gluten, rather than multiple variables, such as dairy and sugar, to ensure accurate assignment of symptoms. Once gluten is reintroduced, people can monitor their symptoms to determine if gluten is the cause of their discomfort and make appropriate dietary adjustments accordingly.

Treating Gluten Intolerance

The only approach to gluten intolerance is to follow a gluten-free diet and address accidental gluten exposure to relieve symptoms and improve overall health. With appropriate care and support, people with gluten intolerance can live healthy, symptom-free lives.

It is important to consult with a healthcare provider to develop a personalized treatment plan that takes into account individual needs and preferences. Proper treatment of gluten intolerance can help people regain control of their health and enjoy a better quality of life.

Following a Gluten Free Diet

By eliminating gluten from their diet, people with gluten intolerance can significantly reduce their symptoms and improve their overall health.

In addition to avoiding gluten-containing foods, people with gluten intolerance should focus on consuming anti-inflammatory foods such as organic animal products, raw dairy products, vegetables, fruits, nuts, seeds and probiotic foods. These dietary changes can help promote healing and reduce inflammation in the body.

Tackling Accidental Gluten Exposure

Accidental gluten exposure can occur despite a person's best efforts to maintain a gluten-free diet, and it is essential to know how to manage these situations effectively. If accidental gluten exposure occurs, people can take measures such as drinking plenty of water, consuming easy-to-digest foods, and avoiding hard-to-digest foods to relieve symptoms.

In addition, drinking ginger or peppermint tea can help soothe an upset stomach and provide relief from digestive discomfort. By being proactive in addressing accidental gluten exposure, people with gluten intolerance can minimize the impact of these incidents on their health and well-being.


Understanding and managing gluten intolerance is essential to maintaining optimal health and well-being. By recognizing the symptoms of gluten intolerance, making a proper diagnosis through medical testing and elimination diets, and adopting a gluten-free diet while addressing accidental gluten exposure, people with gluten intolerance can take control of their health and enjoy a life free from it. discomfort and the complications associated with this condition.

What is Tolerase® G?

What is Tolerase® G?

A New Approach for People with Gluten Sensitivity: Explore the Science and Benefits of Tolerase® G.

Relief from Gluten Sensitivity

In the fight against gluten, there is a unique supplement that stands out: the anti-gluten pills from Little Helpers with 100% Tolerase® G.

This specific enzyme, Tolerase® G, a patented endopeptidase specific for proline, was developed by Royal DSM and has been scientifically proven to be effective in breaking down gluten residues ( 1 ) ​. Additionally, research has shown that Aspergillus niger prolyl endoprotease (AN-PEP), an enzyme closely related to Tolerase® G, can break down gluten so effectively that it barely reaches the duodenum, potentially eliminating gluten's toxicity ( 2 ) ( ​​3 ) ​.

On this page we explain why we are so enthusiastic about this supplement, supported by scientific research.

What are Gluten?

Gluten is a group of proteins found primarily in grains such as wheat, barley and rye. These complex proteins give shape, strength and texture to bread and other grain products. However, gluten is difficult to digest because it is rich in proline, a non-essential amino acid. This is why approximately 13% of the world's population is sensitive to gluten in the diet (1)​.

The Effect of Tolerase® G

It is important to note that Tolerase G is designed to have optimal activity in the difficult conditions of the stomach. Its effectiveness on the digestion of gluten in the stomach and duodenum has been scientifically proven ( 1 ).

Studies have shown that a newly identified prolyl endoprotease, derived from Aspergillus niger, can effectively break down gluten proteins. This enzyme works optimally at a pH of 4-5, remains stable at a pH of 2 and is completely resistant to digestion with pepsin ( 2 ). Additionally, research has shown that Aspergillus niger prolyl endoprotease (AN-PEP) accelerates the breakdown of gluten in the stomach so much that hardly any gluten reaches the duodenum ( 3 ). This implies that co-administration of AN-PEP with a meal containing gluten could potentially eliminate gluten toxicity. This gives people the opportunity to (occasionally) give up their strict gluten-free diet ( 3 ).
