5/5 - (1 vote)

Bullous pemphigoid (BP) is a chronic autoimmune disease that affects the skin. It is characterized by the formation of blisters on the skin, which can be itchy, painful, and disfiguring. While there is no cure for BP, it can be managed with treatment. One important aspect of managing BP is making dietary changes to avoid triggering or worsening symptoms. In this article, we will discuss the foods to avoid with bullous pemphigoid and provide tips on how to make healthier dietary choices for skin health.

Understanding Bullous Pemphigoid

BP is a rare disease that affects people of all ages, but it is more common in older adults. It is caused by an autoimmune response, in which the body’s immune system mistakenly attacks the proteins in the skin. This attack causes the skin to blister. The exact cause of BP is unknown, but it is thought to be triggered by a combination of genetic and environmental factors.

Some people with BP have a family history of the disease, while others develop it after exposure to certain medications, infections, or other environmental triggers. It is important to note that not everyone with BP will have the same triggers, and what may cause symptoms in one person may not affect another.

Foods to Avoid with Bullous Pemphigoid

While there is no specific diet for BP, there are certain foods that may trigger or worsen symptoms. These include:

Gluten is a protein found in wheat, barley, and rye. Some studies have shown a link between gluten intolerance and autoimmune diseases like BP. Therefore, it is recommended to avoid gluten-containing foods such as bread, pasta, cereals, and baked goods if you have BP.

Dairy Products

Dairy products, especially cow’s milk, contain a protein called casein which has been linked to autoimmune diseases. Some people with BP have reported improvement in their symptoms after eliminating dairy from their diet. If you have BP, it is best to avoid cow’s milk, cheese, yogurt, and other dairy products. You can opt for alternatives like almond milk, coconut milk, or soy milk.

Nightshade Vegetables

Nightshade vegetables, such as tomatoes, potatoes, eggplants, and peppers, contain a compound called solanine which has been linked to inflammation and autoimmune diseases. While there is no scientific evidence to support this claim, some people with BP have reported improvement in their symptoms after avoiding nightshade vegetables.

Processed Foods

Processed foods are high in sugar, unhealthy fats, and preservatives, which can trigger inflammation in the body. These include packaged snacks, fast food, frozen meals, and sugary drinks. It is best to limit or avoid these foods if you have BP.

Spicy Foods

Spicy foods can cause irritation and inflammation in the digestive tract, which can worsen symptoms of BP. It is recommended to avoid spicy foods or limit their consumption if you have BP.

Foods to Eat with Bullous Pemphigoid

While there are certain foods to avoid with BP, there are also many healthy options that can help manage symptoms and promote skin health. These include:

Anti-Inflammatory Foods

Inflammation is a major factor in autoimmune diseases like BP. Therefore, incorporating anti-inflammatory foods into your diet can help reduce symptoms and improve overall health. These include fatty fish (salmon, tuna, sardines), leafy greens, berries, nuts, and seeds.

Foods Rich in Antioxidants

Antioxidants help protect the body against damage caused by free radicals, which can contribute to inflammation. Foods rich in antioxidants include colorful fruits and vegetables, green tea, dark chocolate, and spices like turmeric and ginger.

Probiotic Foods

Probiotics are beneficial bacteria that help maintain a healthy balance in the gut microbiome. They have been shown to improve symptoms of autoimmune diseases by reducing inflammation and boosting the immune system. Some probiotic-rich foods include yogurt, kefir, sauerkraut, kimchi, and kombucha.

Healthy Fats

Healthy fats, such as those found in avocados, olive oil, nuts, and fatty fish, can help reduce inflammation and promote skin health. They also provide essential nutrients for overall well-being.

Vitamin D

Vitamin D plays a crucial role in maintaining a healthy immune system and promoting skin health. It is recommended to get vitamin D from natural sources such as sunlight, fatty fish, egg yolks, and fortified foods like milk and cereals.

Foods to Avoid if You Have Bullous Pemphigoid

In addition to specific trigger foods, there are certain dietary habits that can worsen symptoms of BP. These include:

Skipping Meals

Skipping meals or going long periods without eating can cause blood sugar levels to drop, which can trigger inflammation and worsen symptoms of BP. It is important to eat regular, balanced meals throughout the day to maintain stable blood sugar levels.

Crash Dieting

Crash dieting or extreme calorie restriction can weaken the immune system and make it more difficult for the body to fight off infections and heal wounds. This can be especially harmful for people with BP, as their skin is already vulnerable to blisters and wounds.

Excessive Alcohol Consumption

Alcohol consumption can lead to dehydration, which can affect the skin’s ability to heal and repair itself. It can also weaken the immune system and increase inflammation in the body. If you have BP, it is best to limit or avoid alcohol.

What Foods Trigger Bullous Pemphigoid?

As mentioned earlier, not everyone with BP will have the same triggers. Some people may find that certain foods worsen their symptoms, while others may not be affected by those same foods. It is important to pay attention to your body and keep track of any foods that seem to trigger or worsen your symptoms.

In addition to the foods mentioned above, some other common triggers for BP include:

  • Certain medications, such as antibiotics, diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Infections, particularly upper respiratory infections
  • Stress and emotional distress
  • Exposure to extreme temperatures or sunlight


While there is no specific diet for bullous pemphigoid, making healthy dietary choices can help manage symptoms and promote skin health. It is important to avoid trigger foods and incorporate anti-inflammatory, antioxidant-rich, and probiotic foods into your diet. Additionally, maintaining a balanced and regular eating schedule, avoiding crash dieting, and limiting alcohol consumption can also help improve symptoms of BP. Remember to listen to your body and consult with a healthcare professional before making any significant changes to your diet. By making these dietary changes, you can better manage your BP and improve your overall well-being.
