Pernicious anemia is an autoimmune condition that prevents the body from absorbing vitamin B12, leading to a vitamin B12 deficiency. While it is uncommon to develop pernicious anemia due to dietary factors, certain diets can contribute to this condition. For example, vegans and vegetarians may be at risk if their diets do not include enough vitamin B12. Additionally, medical conditions affecting the digestive system, such as celiac disease or Crohn's disease, can hinder vitamin B12 absorption. Treatment for pernicious anemia typically involves vitamin B12 supplements, and dietary changes may also play a role in managing symptoms. Some people adopt the Autoimmune Protocol (AIP) diet, which involves eliminating irritants and inflammatory triggers, such as gluten, refined sugars, and processed foods. While diet is essential, pernicious anemia is primarily treated through vitamin B12 supplementation to restore normal vitamin levels and prevent irreversible damage to the nervous system.

What You'll Learn
Vegetarian and vegan diets
Vegetarians and vegans can ensure they are getting enough vitamin B12 by including foods such as breakfast cereals with added vitamin B12, soy-based beverages, and vegetarian burgers. They can also consider taking vitamin B12 supplements. In addition, a well-balanced vegetarian or vegan diet should include plant-based sources of iron such as raisins, dates, and lotus stem. Citrus fruits, beans, and whole grains are good sources of folate, which is another important nutrient for preventing anaemia.
It is important to note that pernicious anaemia can be sneaky, and one may have this disease for many years before noticing any changes in their body. Early symptoms of pernicious anaemia are often mild and may include feeling tired, lightheaded, or breathless. However, if left untreated, pernicious anaemia can cause serious health issues. Therefore, it is important to be mindful of one's diet and to consult a healthcare professional if any symptoms of anaemia are present.
The AIP diet has been shown to have potent effects against autoimmune diseases, including pernicious anaemia. This diet involves cutting out certain foods for at least a month and then slowly reintroducing them one by one to gauge the body's reaction. It is designed to soothe the immune system, reduce inflammation, and promote healing.

Digestive system issues
Pernicious anaemia is an autoimmune condition that prevents the body from absorbing vitamin B12. This can be caused by a lack of intrinsic factor, which is required to absorb vitamin B12. While pernicious anaemia is typically caused by an intrinsic lack of vitamin B12, dietary factors can also play a role.
Leading scientists believe that the main cause of autoimmune diseases is a "leaky gut". This is when the intestinal barrier function is flawed, allowing proteins, toxins, and other particles to enter the bloodstream. This triggers the immune system, and if these particles resemble the body's own tissues, the body may start attacking its own tissues. Gluten, for example, can pry open the tight junctions of the gut, allowing toxins and food particles into the bloodstream. This can set off inflammatory and autoimmune responses.
The AIP (Autoimmune Protocol) diet has been shown to have potent effects against inflammatory bowel disease. This diet involves cutting out certain foods for at least a month and then slowly reintroducing them one by one to gauge the body's reaction. The AIP diet aims to soothe the immune system, reduce inflammation, and promote healing.

Autoimmune diseases
Pernicious anemia is an autoimmune disease that prevents the body from absorbing vitamin B12. It is a rare condition that affects people of all ages worldwide, particularly those over 60. The term "pernicious" refers to the harm the disease causes to several body systems, including the digestive system and nervous system. If left untreated, it can cause irreversible damage to the nervous system.
The autoimmune nature of the disease means that the body's immune system mistakenly attacks healthy tissue. In the case of pernicious anemia, the immune system attacks the intrinsic factor, a glycoprotein that binds to vitamin B12 and facilitates its transport and absorption. This results in a decrease in red blood cells, as vitamin B12 is essential for their formation.
The exact cause of pernicious anemia is not yet fully understood, but it is believed that a weakened stomach lining (atrophic gastritis) plays a role. This can be due to an autoimmune condition, where the body attacks the intrinsic factor protein or the cells in the stomach lining that produce it. Very rarely, pernicious anemia can be congenital, passed down through families.
There are dietary factors that can influence pernicious anemia. A vegan or vegetarian diet that does not include enough vitamin B12 can contribute to the condition. Additionally, certain medical conditions, such as celiac disease or Crohn's disease, can affect the absorption of vitamin B12. However, once pernicious anemia is diagnosed, dietary changes alone are usually not sufficient to treat the condition. Lifelong vitamin B12 supplementation is typically required to manage the disease and prevent serious complications.
Some people with pernicious anemia may find that certain diets help to manage their symptoms. The Autoimmune Protocol (AIP) diet, for example, aims to eliminate irritants and offenders to gut health, reduce inflammation, and promote healing. This involves cutting out certain foods for at least a month and then slowly reintroducing them one by one to gauge the body's reaction. Gluten-free diets have also been found to be beneficial for some people with autoimmune diseases, including pernicious anemia.

Lack of intrinsic factor
Pernicious anemia is an autoimmune condition that affects the stomach and prevents the body from absorbing vitamin B12. This is because pernicious anemia causes the immune system to attack the cells that produce intrinsic factor, a protein made in the stomach that helps the body absorb vitamin B12. Without intrinsic factor, the body cannot absorb vitamin B12, leading to a deficiency.
Vitamin B12 is essential for the production of healthy red blood cells, which carry oxygen around the body. A deficiency in vitamin B12 results in a reduced number of red blood cells, causing pernicious anemia. This can lead to serious medical issues, including irreversible damage to the nervous system, digestive system problems, heart problems, and weakness and fatigue. Older adults, especially those over 60 of Northern European or African ancestry, are more likely to develop pernicious anemia due to digestive problems that make it harder to absorb vitamin B12.
While pernicious anemia is primarily caused by the lack of intrinsic factor due to the body attacking its own cells, certain dietary and lifestyle factors can also contribute to vitamin B12 deficiency. For example, a strict vegetarian or vegan diet that does not include enough vitamin B12 can increase the risk of pernicious anemia. However, this is rare, and in the United States, vitamin B12 deficiency is usually due to other risk factors. Drinking too much alcohol can also interfere with the absorption of vitamin B12.
Treatment for pernicious anemia typically involves lifelong vitamin B12 supplements in the form of shots, nose sprays, or oral medication. In addition to medical treatment, dietary changes can help manage pernicious anemia. The Autoimmune Protocol (AIP) diet, for example, aims to eliminate irritants and offenders to gut health, reduce inflammation, and promote healing. This involves cutting out certain foods for at least a month and then slowly reintroducing them one by one to gauge the body's reaction. Refined sugars, processed products, food additives, seed oils, grains, and legumes are often eliminated, while ensuring adequate intake of potassium and folate.
It is important to note that dietary changes alone may not be sufficient to treat pernicious anemia, as it is primarily caused by the lack of intrinsic factor rather than solely dietary deficiencies. However, dietary interventions like the AIP diet can help manage symptoms and promote overall gut health. Consulting a healthcare provider is crucial to determine the most appropriate treatment plan, which may include a combination of medical interventions and dietary modifications.

Gluten intolerance
Coeliac disease damages the small intestine, which is where the body absorbs vitamin B12, along with iron and folate. This damage reduces the absorption of these nutrients, leading to a potential vitamin B12 deficiency and, consequently, pernicious anaemia.
Gluten-free diets are often recommended for those with coeliac disease or non-coeliac gluten sensitivity, as they can help alleviate symptoms and improve nutrient absorption. In fact, a gluten-free diet is the primary treatment for coeliac disease, and it can take between two and 18 months for nutritional deficiencies to be corrected.
A gluten-free diet can also help against other autoimmune diseases, such as type 1 diabetes, rheumatoid arthritis, autoimmune hepatitis, and multiple sclerosis. The Autoimmune Protocol (AIP) diet, for example, eliminates certain foods for a month and then slowly reintroduces them one by one to gauge the body's reaction. This diet has been shown to have potent effects against inflammatory bowel disease, with 11 out of 15 people achieving total remission by the sixth week.
It is important to note that pernicious anaemia can develop slowly and go unnoticed for years. However, if left untreated, it can cause serious medical issues, including irreversible damage to the nervous system. Therefore, it is crucial to consult a healthcare provider for a thorough examination and appropriate treatment.
