Are you suffering from rashes that are red, raised, and itchy? 

Do they come and go suddenly? 

Do you experience sudden swellings on your lips, eyelids, or throat? 

You might be suffering from Urticaria or even a related condition called angioedema, which is a deeper form of swelling that may accompany or resemble Urticaria. 

Urticaria as well as Angioedema, both occur because of various allergens, stress, certain foods, or even temperature changes, and they not only disturb your daily comfort but also your peace of mind. 

You have to adopt a well-balanced dietary practice that may require a combination of Ayurvedic, and a modern diet. A balanced diet can play a significant role in managing and reducing the recurrence of allergic reactions. 

Let’s discuss various diet types that, if you follow with all caution, are not only effective for Urticaria but also supportive in managing milder forms of different types of angioedema. 

You can also follow our expert Dr. Sahil Gupta’s dietary guidelines for Urticaria and various other skin issues and for a personalized diet for Urticaria, consult Dr. Sahil Gupta at IAFA Allergy.

Diet Guide for Urticaria

Food is one of the three pillars of life, known as Tryoupstambha. There is a saying by Vaidya Jeevana:

Pathye Sati Gadaarthasaya Kimoushada Nishevanaih |

Pathye Asati Gadaarthasaya Kimoushadha Nishevanaiih ||

If you follow a wholesome diet and regime, then there is no need for medicine, and if you don’t follow a wholesome diet and regime then also there is no use of medicine.

So, the following dos (Pathya) and don’ts (Apathya) are very important for the proper treatment of diseases.

Pathya (Wholesome/ Meals to be Taken) for a Patient With Urticaria

As per Ayurvedic classical literature, Urticaria is mainly correlated with Sheeta Pitta and comes under Kustha Roga. 

So here, the Pathya you follow for Sheeta Pitta, can also considered as Pathya for Urticaria and Angioedema, which is a deeper form of swelling that may accompany or resemble Urticaria. 

Substances that pacify Pitta and Kapha Dosha, and those with Katu (pungent), Tikta (bitter), and Kashaya (astringent) tastes are all considered Pathya (wholesome).

3. Pathya & Apathya in Urticaria

Dietary Guidelines for Urticaria(Modern Point of View)

1. Low- Salicylate Diet

#1. What Are Salicylates?

Salicylates are natural chemicals found in many fruits, vegetables, and spices, those act as a preservative and protect plants from various diseases, environmental stress and pests.

They are also present in certain medications like Aspirin.

#2. How Do Salicylates Affect Urticaria?

You may or may not be sensitive to salicylates but some individuals are sensitive to Salicylates, which may result in symptoms like hives, asthma, and digestive issues, upon consumption.

In chronic Urticaria, salicylate-containing food can worsen histamine release, and lead to hives, swelling, and itching. It also inhibits prostaglandin synthesis which interferes with arachidonic acid metabolism which leads to various inflammatory responses. 

You can include a low-salicylate diet in your routine and avoid foods mentioned below to pacify the symptoms. 

#3. Foods to include in Low-Salicylate Diet

• Grains like rice, and oats
• Vegetables like cauliflower, zucchini, and cabbage
• Fruits like bananas, and pears
• Dairy alternatives like rice milk.
• You can include fresh meats, and eggs for protein

#4. Foods to Avoid in Low-Salicylate Diet

• Spices to avoid are curry powder and paprika
• Fruits like berries, oranges, and grapes
• Vegetables like tomatoes, and spinach
• Avoid beverages like tea and coffee 
• Say no to processed foods with artificial additives

#5. Effective Ayurvedic Herbs

• Amla (Emblica officinalis): Amalaki is rich in vitamin C, which supports the immune system and skin health.
• Shatavari (Asparagus racemosus): Shatavari helps in balancing the body’s responses and reducing inflammation in the body.
• Mulethi (Glycyrrhiza glabra): Mulethi has soothing properties.

2. Low-Amines Diet

#1. What Are Amines?

Amines are naturally occurring compounds derived from amino acids or breakdown of proteins. Amines are found in various types of foods, especially those that are fermented, or processed and aged. 

Common types of foods that have amines include histamine, tyramine, putrescine and phenylethylamine but the most relevant for Urticaria is histamine. These compounds can trigger allergic-like reactions in you are sensitive to Amines such as Histamine.

#2. How Do Amines Affect Urticaria?

When you eat amines-rich food, you get allergic reactions such as hives, because of amine’s vasoactive properties. By triggering mast cell degranulation amines especially histamine mimics various allergy symptoms. 

This is not a true allergy but a chemical sensitivity, where your body reacts to these compounds, leading to symptoms like swelling, itching, and flushing.

If you have histamine intolerance or DAO enzyme deficiency, amines are not able to break down properly during digestion, leading to histamine overload or Urticarial flare-up.

#3. Foods to include in low- amine diet: 

• Fresh meat but to be consumed immediately after cooking.
• Poultry but to be consumed immediately after cooking.
• Fresh fruits like apples, pears, and watermelon
• Fresh vegetables like carrots, zucchini, and lettuce
• Grains like oats, quinoa, and rice
• Dairy alternatives like rice milk, and coconut milk

#4. Foods to avoid in low- amine diet: 

• Avoid aged cheeses like cheddar, and blue cheese
• Processed meats like salami, and pepperoni
• All types of fermented foods like soy sauce, and Bhatura
• Alcoholic beverages like wine, and beer
• Overripe fruits like bananas, and avocados

#5. Ayurvedic Herbs that can be included:

• Neem (Azadirachta indica): As Neem has detoxifying properties, it can help purify the blood and reduce skin inflammation.
• Guduchi (Tinospora cordifolia): An immunomodulator herb that helps in balancing the body’s response to various types of allergens and is helpful in the case of Urticaria.
• Haridra (Curcuma longa): Haridra has anti-inflammatory properties beneficial for various skin conditions including Urticaria.

3. Anti-inflammatory Diet

#1. What is an anti-inflammatory diet?

Chronic Urticaria involves inflammation of the skin. An anti-inflammatory diet contains food that minimizes your chances of having inflammation. Anti-inflammatory foods help to lower the chances of having flare-ups of Urticaria. 

Since the anti-inflammatory diet is rich in antioxidants, it helps to cope with free radicals caused by external factors like stress, and smoking. These free radicals in the body exacerbate the rashes and frequency of flare-ups.

#2. Aim of an anti-inflammatory diet in Urticaria

In an anti-inflammatory diet, focus is made on foods that reduce systemic inflammation in your body, which is primary reason for various allergic reactions and chronic skin issues. 

An anti-inflammatory diet reduces histamine release and soothes the Urticaria symptoms.

#3. What’s included in an anti-inflammatory diet?

• Antioxidant rich fruits and vegetables: Fruits and vegetables like citrus fruits, spinach, berries, kale, broccoli, and bell peppers that are rich in antioxidants like Vitamin C, E, and beta-carotene, which combat oxidative stress.
• Probiotic-rich food: Yogurt, kimchi, and buttermilk helps in managing systemic inflammation and various immune responses.
• Omega-3 Fatty Acids: They act as an anti-inflammatory fat that reduces airway inflammation and thus helps in various skin issues including Urticaria. Omega-3 Fatty Acids rich foods are chia seeds, flaxseeds, walnuts, fatty fish -salmon, and sardines.
• Whole Grains: whole grains help in reducing the inflammation in your body. Consume grains such as whole wheat, oats, brown rice, and quinoa.
• Include nuts and seeds: Nuts and seeds like sunflower seeds, flaxseeds, and walnuts provide healthy fats and vitamin E to your body. 
• Spices: Like ginger, garlic, and turmeric act as natural anti-inflammatories
• Green Tea: Green tea is best for immunomodulation as it is rich in polyphenols like EGCG.

#4. What foods should be avoided in an anti-inflammatory diet?

• Avoid refined sugar, trans fats, and red meat.
• Processed food that is high in unhealthy additives and fats  
• Avoid dairy products if you have mucus problem
• Avoid caffeine and alcohol
• Trans fats that are found in packaged snacks, and fried foods
• Avoid high histamine food like fermented foods, processed meat, smoked meat, cheese, tomato, spinach, and seafood.

#5. Sample anti-inflammatory diet for Urticaria

4. Autoimmune Protocol (AIP) Diet

#1. What is the AIP diet?

The Autoimmune Protocol (AIP) diet is a strict elimination diet designed to reduce inflammation and manage autoimmune diseases by eliminating potential dietary triggers. This diet helps in reducing inflammation, regulating the immune system.

AIP is a more restrictive version of the paleo diet.

#2. How Does the AIP Diet Affect Urticaria?

The AIP diet can help in identifying and eliminating foods that exacerbate symptoms in patients with autoimmune-related Urticaria. The diet helps in reducing triggers by removing high histamines and inflammatory foods like nightshade.

AIP diet also supports skin repair as this diet is rich in vitamin A, C, collagen, and zinc.

#3. AIP Diet Phases

AIP diet has two phases:

• The elimination phase
• The reintroduction phase

i) The elimination phase 

• In this phase, you have to eliminate the food from your diet that causes inflammation, imbalance in good and bad bacteria in the gut, or increases the immune response sensitivity.

• You should avoid foods like seeds, nuts, grains, legumes, eggs, dairy, and nightshade vegetables.
• Also avoid coffee, food additives, alcohol, and tobacco.
• Along with this, improve your lifestyle like sleep cycle, and increase physical activity.
• Start adding nutrient-dense foods like fermented food, bone broth, and minimally processed meat in your diet.

Duration of elimination phase: This phase varies from patient to patient. You have to continue with this phase until you start seeing improvement in your symptoms.

ii) The reintroduction phase

• As soon as you see improvement in your symptoms, start the reintroduction phase.
• In this phase, you have to introduce all the food that is eliminated during the elimination phase one by one, based on your tolerance to each food.
• The goal of this reintroduction phase is to understand which food is specifically contributing to your symptoms or flare ups. So you can decide what to include and what to eliminate for better health.

#4. Foods to include in the AIP diet

• Include vegetables like carrots, sweet potatoes, and leafy greens in your diet.
• Fruits like berries, apples, and bananas
• You can get proteins from grass-fed meats, and fish
• Healthy fats like olive oil, and coconut oil
• If you can tolerate fermented foods, then add them as well.

#5. Foods to avoid in the AIP diet

• Avoid grains and legumes
• Dairy products.
• Night-shade vegetables like tomatoes, eggplants, and peppers
• Nuts and seeds  
• Processed foods and refined sugars

#6. Ayurvedic Herbs that can be included:

• Ashwagandha (Withania somnifera): Ashwagandha is an adaptogen that helps in managing stress and supporting immune function.
• Brahmi (Bacopa monnieri): Brahmi helps in supporting cognitive function and reduces stress.
• Turmeric (Curcuma longa): Turmeric helps in reducing inflammation and supports overall health.

5. Antihistamine diet

#1. What is Histamine?

Histamine is a biogenic amine which plays a vital role in immune responses, neurotransmission, and digestion.

Histamine is primarily stored in the mast cells, which is derived from amino acid histidine. These mast cells and basophils release this histamine in response to allergens, infections, and injury.

#2. What are the functions of Histamine?

Histamine is a key player in allergies as when it is released when any allergen detects various symptoms like inflammation, or swelling occurs. 

Along with this histamine stimulates production of gastric acid, acts as neurotransmitter in the brain, and regulates vasodilation (widening of blood vessels) to protect from allergens.

#3. When does histamine become the culprit?

Histamine is essential for many physiological processes, but problems arise when they are overproduced or not broken properly which leads to various issues like allergies, histamine intolerance, migraines, and digestive problems.

#4. Role of Histamine in Urticaria

In Urticaria, whether it is acute or chronic, mast cells release histamine, which leads to hives, and itching.  

In chronic Urticaria, histamine intolerance may occur where the body either overproduces histamine in the body or cannot break it down effectively due to low DAO enzyme (diamine oxidase) and results in these symptoms.

#5. Food to include in Antihistamine

Food to include in an antihistamine diet which is naturally low in histamine or supports its breakdown effectively are as follows.

• Fresh vegetables like bottle gourd (Lauki), ridge gourd (tori), zucchini, carrots, and spinach (cooked).
• Low-histamine fruits like apples, pears, papaya, watermelon, and blueberries.
• Gluten-free diet like rice, quinoa, millets like bajra, and jowar.
• Fresh meats like chicken, turkey, and fresh lamb are not aged or processed.
• Healthy fats like cold-pressed olive oil, flaxseed oil, and coconut oil.
• Herbal teas like chamomile, tulsi, and coriander-cumin-fennel tea.
• Various Ayurvedic herbs like Guduchi, Haridra, Amla, Neem, and Manjistha 
• Gut-healing foods like bone broth if tolerated 
• Ghee (Clarified butter) and soaked/peeled almonds

#6. Food to avoid in an antihistamine diet

#7. Ayurvedic herbs that can be included in an antihistamine diet

You can include herbs like Haridra, Manjistha, and Triphala, which helps in Pitta-Kapha imbalance, Rakta Dushti, and Ama accumulation is common in chronic Urticaria.

Consult an Ayurvedic practitioner that will prescribe herbs based on your prakriti and dosha involvement in Urticaria.

6. Gluten-free Diet

#1. What is a gluten-free diet?

Gluten is a type of protein that is mainly found in rye, barley, wheat, and triticale (a cross hybrid between wheat and rye). A gluten-free diet means, excluding the diet that contains gluten.

A survey suggests that people who are sensitive to gluten, have non-celiac gluten sensitivity or celiac diseases (an autoimmune disorder) experience Urticaria as it is the contributing factor. So, avoid gluten to check whether your symptoms are improving. 

#2. Role of gluten in Urticaria?

As we know that celiac disease is an autoimmune disorder that is triggered by gluten and in few cases chronic Urticaria may be the extra intestinal manifestation of celiac disease. And when you take the gluten-free diet, Urticaria symptoms are resolved. 

Patients suffering from NCGS (non- celiac gluten sensitivity) also suffer from symptoms like Urticaria, and headaches. So, cases of Urticaria associated with gluten-related disorders are benefited by a gluten-free diet.

#3. What can you include in your diet:

• Vegetables: Green leafy vegetables, all types of gourds like snake gourd, ivy gourd, bottle gourd, bitter gourds, Indian round gourd (Tinda), and lady finger.
• Fruits: Banana, Grape, Mousambi, Blackberry, blueberry, Cranberry, Cherry, Papaya, Citrus fruits.
• Cereals: Oats, Bajra, Ragi, Rice.
• Pulses: Beans like kidney, pinto, back eyes, French, cluster beans, Red gram, andGreen gram.

#4. What to avoid:

• Wheat
• Barley
• Rye
• Oats in a few cases
• Triticale.

#5. Plant-based anti-allergic diet

In plant based diet, your primarily eat foods from plant sources. The diet emphasizes whole, minimally processed plant foods and also limits or excludes animal products.

Types of Plant-Based Diets:

What does a plant-based diet include?

• Vegetables, and fruits
• Whole grains like brown rice, oats, and quinoa
• Legumes like beans, lentils, chickpeas, 
• Nuts and seeds
• Plant-based oils like olive oil, avocado oil, 
• Various herbs and spices.

Which are the foods you should limit or exclude while on a plant-based diet?

You should avoid or limit meat (any red or white), highly processed food like trans fats, white flour products, poultry, and fish, if you are on a plant-based diet.

7. Casein free diet

#1. What is a Casein-Free Diet?

Casein is a type of protein primarily found in milk products. Casein-free diet includes eliminating all sources of casein, a protein found in milk and dairy products. 

You can go with it if you have casein allergy, milk intolerance, autoimmune conditions, inflammatory conditions or chronic skin conditions including Urticaria (hives).

What is Casein?

The main protein in cow’s milk which is 80% of total milk protein is casein. You can get it in yogurt, butter, cream, cheese and other dairy-based products. 

Like gluten, casein can trigger immune responses in sensitive individuals and result in various skin disorders including Urticaria.

#2. How does Casein affect Urticaria?

An IgE-mediated allergic reaction to casein can cause immediate Urticaria, swelling, itching, and even anaphylaxis in the patient and it is more common in infants and children and even it persists in adults in a few cases. 

In cases without full allergy, poor digestion of casein in the body may increase intestinal permeability i.e. leaky gut, which triggers systemic immune responses in the body, including chronic Urticaria. 

In a few cases, casein can also cause low-grade chronic inflammation contributing to autoimmune or idiopathic Urticaria. 

As per Ayurveda, dairy mainly cow’s milk is Snigdha (unctuous) and Kapha-promoting in nature, which may aggravate Urticaria (Sheeta Pitta) in Kapha–Pitta Prakriti individuals. 

So you should consume milk-free and light diets (Laghu Aahara) if you are experiencing any of the above symptoms. The casein-free diet aligns with the principles of Ama-reduction, Shodhana, and Ruksha-Ahara.

#3. Types of Casein-Free Diets

• Strict casein-free diet- Avoids all dairy and milk protein completely, including hidden casein in processed foods.  
• Casein-free and gluten-free diet – Often both diets are combined in skin disorder to reduce combined inflammatory triggers.
• Vegan Diet- Naturally casein-free diet, no animal milk, also in such type of sites avoids eggs and other animal products
• Elimination Diet- In this type of casein-free diet, you temporarily avoid casein rich foods to monitor its role in Urticaria and reintroduce it later under supervision to see its effect.

#4. Foods to Include in a Casein-Free Diet

• Consume grains like rice, oats, quinoa, millet, corn,and  amaranth,  
• Proteins like eggs if tolerated, legumes, beans, soy, lentils, tofu, meats, poultry, and fish.
• Dairy Substitutes like coconut milk, almond milk, soy milk, oat milk, and rice milk 
• Vegetables like all fresh vegetables, especially bitter and astringent ones .
• All fresh fruits, especially apples, pears, berries, and pomegranates
• Butter Substitutes like coconut oil, olive oil, avocado oil, and ghee from non-cow milk (if tolerated)
• Desserts that are dairy-free or vegan desserts made from plant-based milk
• Seasoning herbs, spices, rock salt, turmeric, ginger, cumin, and fennel

#5. Foods to Avoid in a Casein-Free Diet

• Avoid processed foods as they  may contain milk solids, caseinates, whey, and sodium caseinate
• Milk chocolates
• Bakery items like cakes, pastries, and biscuits, should be avoided unless dairy-free.
• Protein Powders mainly whey protein and casein protein

Note: You should read labels for hidden ingredients like casein, sodium caseinate, calcium caseinate, milk protein, and whey protein concentrate, before eating any packed food.

#6. Who Should Try a Casein-Free Diet?

You should go for a casein-free diet, if you experience –

• Urticaria after milky and dairy consumption.
• A cow milk allergy or casein intolerance.
• Chronic idiopathic Urticaria unresponsive to various medications.
• Following an elimination diet to identify triggers

8. FODMAP Diet (For Gut Mediated Urticaria)

#1. What is FODMAP?

FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. 

FODMAP is a carbohydrate that is difficult to digest as it pulls more water to the bowel and increases bloating, gas, pain, and diarrhea.

In this specialized eating plan, you have to limit certain short carbohydrates that are poorly absorbed in your guts to track symptoms. 

Who uses the FODMAP Diet?

Originally the FODMAP diet was developed for Irritable Bowel Syndrome (IBS) and bloating symptoms. FODMAP diet is also effective in Small intestinal bacterial overgrowth (SIBO), various functional GI disorders, along with some skin conditions like Urticaria, where gut health plays an important role.

#2. Role of FODMAP diet with Urticaria

Though FODMAP is not a classical treatment of Urticaria, this diet may help you if Urticaria is associated with inflammation of the gut, dysbiosis, or histamine intolerance. 

Some high-FODMAP foods are rich in histamine or histamine liberators, worsening histamine-mediated Urticaria. 

When the gut is inflamed, it becomes ‘leaky.’ Leaky gut lets the toxins and allergens enter the blood, at that point the body’s immune system can trigger systemic skin symptoms, including Urticaria.

#3. FODMAP Diet Phases

• Elimination Phase (2–6 weeks): Remove all high-FODMAP foods.
• Reintroduction Phase (6–8 weeks): Gradually add one FODMAP group at a time to test tolerance.
• Personalization Phase: Maintain a long-term modified diet based on what is tolerated.

#4. Foods low in FODMAP

• Eggs
• Meat
• Rice
• Quinoa
• Fruits like blueberries, grapes, strawberries, and oranges
• Vegetables like eggplant, green beans, pumpkin, carrot, and zucchini

#5. Foods to Avoid

• Fruits like mango, plum, apple, watermelon, and peach.
• Vegetables, like broccoli, onion, asparagus, and artichokes.
• High fructose corn syrup.
• Legumes like lentils, kidney beans, chickpeas
• Lactose should also be avoided if you are intolerant.

9. Low Histamine Diet

#1. How Does Histamine Affect Urticaria?

In individuals with histamine intolerance, the body cannot break down histamine efficiently, leading to its accumulation and triggering symptoms such as Urticaria, headaches, and digestive issues.

Histamine stimulates the production of gastric acid, acts as a neurotransmitter in the brain, and regulates vasodilation. 

As it is essential for many physiological processes, problems arise when they are overproduced or not broken down properly, which leads to various issues like allergies, histamine intolerance, migraines, digestive problems, skin issues like Urticaria. So, individuals with skin issues like Urticaria should take a low-histamine diet.

• Principle of low histamine diet: Intake of a low histamine diet helps individuals with histamine intolerance or overproduction, which can mimic or worsen various skin conditions.
• What to include in a low histamine diet: Freshly cooked meat, fish, fresh fruits, vegetables, gluten-free grains like rice and quinoa.
• What to Avoid: Fermented foods like cheese, vinegar, wine, aged cheese, smoked meats, spinach, eggplant (brinjal), tomatoes (naturally high in histamine), and leftover foods.

10. Mediterranean diet

The Mediterranean diet is plant-based, an interest which began in the 1950s. This diet is based on the traditional cuisines of the countries that border the Mediterranean Sea like Greece, and Italy.

The Mediterranean diet is recommended mainly for heart diseases, but it gives wonderful results for Crohn’s disease, various skin disorders. According to a recent study published in Gastroenterology, the Mediterranean diet will improve inflammation, symptoms, and quality of life.

#1. What is included in the Mediterranean diet?

• Plant-based various foods like vegetables, legumes, fruits, herbs, spices, nuts, and seeds are included in the diet.
• In this diet seafood, dairy, fish, and poultry are included in moderation, and sweets and red meat are eaten occasionally. 
• Olive oil which provides mono-saturated fats is the main source of healthy fats in this diet.
• Wine is also associated with this diet, but it is taken in moderation.

#2. How can you plan for a Mediterranean diet?

• First start including vegetables, whole grains, and beans in your diet.
• In the Mediterranean diet, fish can be included in the diet at least twice a week.
• Serve fresh fruits for dessert instead of sweets
• Use olives for the preparation of food instead of other oils or butter.

#3. Special nutrients for patients with Urticaria

Common Deficiencies in Chronic Urticaria are as follows:

• Vitamin D: The most common deficiency linked with vitamin D is autoimmune Urticaria.
• Vitamin C: The deficiency of Vitamin D lowered the histamine breakdown.
• Zinc & B12: The deficiency of vitamin B12 and zinc in the body compromises immunity.
• Iron: Deficiency of iron especially in women, can worsen skin symptoms and flare up Urticaria.

Tips for Optimal Nutrient Absorption in case of Urticaria

• Take iron-rich foods with Vitamin C, take beetroot with amla juice.
• To prevent mineral loss, avoid tea and coffee right after meals to prevent mineral loss.
• Use healthy fats and ghee (clarified butter) for better fat-soluble vitamin (A, D, E, K) absorption.
• Avoid antacids and frequent use of antibiotics, which reduce B12, iron, and magnesium absorption in your body.

Ayurvedic Herbs Rich in Nutrients that you can take in Urticaria

When to specially take this nutrient in case of Urticaria, when –

• There’s a confirmed deficiency by pathological test.
• Diet is restricted to gluten-free, dairy-free, and vegan due to Urticaria.
• Chronic Urticaria is resistant to dietary and lifestyle changes.
• A patient is under high stress or has autoimmune involvement.

Strategies for diets in chronic spontaneous Urticaria(CSU) are controversial. This systematic review assessed the interest in diet for managing CSU. We searched for original reports in MEDLINE, EMBASE, CENTRAL, and LILACS. Among the 278 reports screened, 20 were included, involving 1,734 patients. Reports described 3 types of systematic diet: pseudo-allergen-free diet (n = 1,555 patients), low-histamine diet (n = 223), and diet without fish products (n = 47), which induced complete remission in 4.8%, 11.7% and 10.6% of patients, respectively, and partial remission in 37.0%, 43.9% and 4.3%. Eight reports described personalized exclusion diets (66 patients) adapted to symptoms/allergological test results and led to complete remission in 74.6% of patients, although the diagnosis of CSU was doubtful. No comparative random studies of diets were available. The only randomized studies were based on oral provocation tests with the suspected responsible diet. Population and outcomes were heterogeneous. In conclusion, there is evidence for the benefit of diets in CSU only in individual patients with clinical symptoms. However, the level of evidence is low for the benefit of systematic diets in CSU because systematic double-blind controlled trials of diet are lacking.

International Journal of Research in Dermatology. 7. 822. 10. 18203/ issn. 2455-4529. Int. J. Res. Dermatol. 20214208. Urticaria (‘hives’ or ‘nettle rash’) consists of blanchable, erythematous, edematous papules or wheals. These wheels vary in size from 1 mm to many centimeters and are usually very itchy. They are caused by vasoactive mediators, predominantly histamine, released from mast cells. In the majority of cases, the wheels are transient, lasting for only a few hours in any one place, but with new wheels appearing in other places. The study aimed to assess the knowledge, attitude, and behavior toward Urticaria and diet among patients. A cross-sectional study was done among Urticarial patients visiting DVL OPD at Sree Balaji Medical College and Hospital using a self-reported questionnaire from January to February 2021. The questionnaire was designed in a manner that the general population could understand and was distributed randomly irrespective of gender. A sample size of 50 was taken. The results of the study revealed that most of the patients had knowledge about Urticaria and were aware of their trigger factors. Regarding behavior, most of the patients were ready to do lifestyle modifications. Regarding attitude, Urticarial patients had no problems mingling with the normal people. Urticaria is a relapsing condition with an impact on quality of life. Specific elimination diets have observed high rates of response after 3 weeks. It has been confirmed that some patients experience worsening symptoms after ingestion of foods including food additives as well as foods such as tomatoes, herbs, seafood, alcohol, and others.

Revista da Associação Médica Brasileira. 67. 675- 680. 10. 1590/ 1806- 9282. 20201076. Patients with chronic spontaneous Urticaria often want to be informed about dietary modifications. There have been many studies evaluating dietary approaches in chronic spontaneous Urticaria. In this study, we aimed to investigate the relationship between adherence to the Mediterranean diet and chronic spontaneous Urticaria. In this cross-sectional case-control observational study, 100 patients (70 males and 30 females, mean age: 38.6±13.0 years) with chronic spontaneous Urticaria and age- and sex-matched 100 healthy controls 70 males and 30 females, mean age: 38.7±13.8 years) were enrolled. A validated 14-item questionnaire evaluating the Mediterranean diet score was used for the assessment of adherence to the Mediterranean diet. The severity and the control of chronic spontaneous Urticaria  were assessed by Urticaria Activity Score over 7 days and Urticaria Control Test, respectively. The mean Mediterranean diet score in the patient group was 5.40±1.88, whereas in healthy controls it was 6.30± 1.39 (p< 0.001). The Urticaria Activity Score over 7 days score of the patients was negatively correlated with the Mediterranean diet score, whereas the Urticaria Control Test score was positively correlated. Reported that adherence to the Mediterranean diet may be an independent factor that decreases the risk of chronic spontaneous Urticaria. It may also reduce the severity of chronic spontaneous Urticaria symptoms.

Chronic Urticaria is characterized by recurrent hives, with or without angioedema, persisting for 6 weeks or longer. Although often suspected by patients, specific allergen triggers are infrequent. In contrast, the condition may be associated with autoimmune and thyroid disorders. While some evidence suggests an association of chronic Urticaria with vitamin D levels, measurement of vitamin D or supplementation is not a part of diagnostic or treatment recommendations. We present a case of a 14-year-old white boy with refractory chronic Urticaria who experienced prompt remission with high-dose vitamin D repletion when vitamin D deficiency was identified as an incidental finding. In some patients, vitamin D may have a role in the pathophysiology and treatment of chronic Urticaria.

European Journal of Clinical Nutrition, 54(2), 155- 158. https:// doi. org/ 10. 1038/ sj. ejcn. 16000- 911. This study aimed to evaluate the effects of an oligoantigenic and histamine-free diet on patients affected with chronic idiopathic Urticaria(CIU). Ten patients with chronic idiopathic Urticaria were prescribed an oligoantigenic and histamine-free diet for 21 days, followed by serial and controlled reintroduction of foods for a further 70 days. Modification in clinical illness, as well as histamine plasma levels, post-heparin plasma diamine oxidase (DAO), and intestinal permeability, were evaluated. The oligoantigenic and histamine-free diet induced a significant improvement in symptoms (P<0.05). Moreover, CIU patients on a free diet showed higher histamine plasma levels (P<0.05 vs post-diet and controls) that fell to control levels during the oligoantigenic and histamine-free diet. Post-heparin plasma diamine oxidase values were slightly reduced and were unchanged during the diet as well as intestinal permeability, which was always normal in all patients. These data suggest that histamine plays a major role in chronic idiopathic Urticaria. The finding of normal intestinal permeability suggests that morphological damage of intestinal mucosa should be excluded in these patients. However, the presence of low levels of post-heparin plasma diamine oxidase may indicate a subclinical impairment of small bowel enterocyte function that could induce a higher sensitivity to histamine-rich or histamine-producing food.
