Psoriasis is an inflammatory autoimmune disease that affects the skin. While there is no single diet-related cure for psoriasis, an anti-inflammatory diet may help manage the condition and prevent flare-ups. This involves eating foods with anti-inflammatory properties, such as omega-3 fatty acids, fibre, and antioxidants. A well-balanced, whole-foods diet is recommended, including fruits, vegetables, whole grains, lean meats, and low-fat dairy. Some people with psoriasis may also benefit from a gluten-free diet, especially if they have celiac disease or a gluten allergy.

Anti-inflammatory foods that help prevent psoriasis flare-ups
Psoriasis is a chronic inflammatory skin disease. While there is no single diet-related cure for psoriasis, an anti-inflammatory diet is one tool that can help manage the condition. A well-balanced diet with anti-inflammatory foods can help reduce flare-ups and the severity of psoriasis symptoms.
An anti-inflammatory diet includes foods that reduce inflammation in the body. These foods are typically less processed and closer to their original state, retaining more fiber and antioxidants. Eating anti-inflammatory foods can help manage psoriasis symptoms and reduce the chances of flare-ups.
Some foods to include in an anti-inflammatory diet for psoriasis are:
- Omega-3 fatty acids: Found in fatty marine fish (such as herring, sardines, salmon, tuna, and mackerel), seafood, vegetable oils (like rapeseed oil, linseed oil, and walnut oil), and nuts (especially walnuts).
- High-fiber fruits and vegetables: Such as leafy greens, blueberries, carrots, and pears.
- Healthy fats: Found in foods like avocados, extra-virgin olive oil, and walnuts.
- High-quality proteins: Including beans, lentils, Greek yogurt, and eggs.
- Antioxidants: Vitamin A, vitamin C, vitamin E, carotenoids, flavonoids, and selenium.
- Vitamin D: Found in beef liver, egg yolk, and Swiss cheese.
In addition to incorporating anti-inflammatory foods, it is important to limit or avoid inflammatory foods that can trigger psoriasis flare-ups. These include excessive alcohol consumption, dairy products high in fat, and added sugars. Some people with psoriasis may also benefit from reducing gluten in their diet or following a gluten-free diet if they have celiac disease.

Gluten-free diets and psoriasis
Psoriasis is a chronic inflammatory skin disease characterised by red, scaly patches on the skin that can be itchy or painful. It is an autoimmune disease, meaning that the body's immune system mistakenly attacks its own healthy tissue. While psoriasis is not caused by diet, certain foods are known to cause inflammation throughout the body, and this can worsen the symptoms of psoriasis.
Research has shown that people with psoriasis are more likely to have celiac disease, a condition marked by sensitivity to dietary gluten. Gluten is a type of protein found in wheat products and other grains. Some people suggest that gluten may trigger or worsen psoriasis symptoms, particularly in those with gluten sensitivity or celiac disease. A 2017 study found that 36% of participants with psoriasis followed a gluten-free diet, and 53% of those who avoided gluten reported notable improvements in their symptoms. Another study found that 73% of psoriasis patients with elevated antigliadin antibodies (AGA) showed an improvement in their psoriasis area and severity index (PASI) after following a gluten-free diet for three months.
However, the relationship between gluten and psoriasis is not clear, and research on this topic has produced mixed results. For example, a 2019 study of 85,185 participants found no link between gluten intake and the onset of psoriasis, suggesting that gluten does not cause the disease. The medical board of the National Psoriasis Foundation has also given only a weak recommendation for a gluten-free diet, suggesting that it may only be beneficial for those with celiac disease or gluten sensitivity.
Overall, while a gluten-free diet may help improve psoriasis symptoms in some people, particularly those with gluten sensitivity or celiac disease, it is not a guaranteed solution for everyone. It is always best to consult with a healthcare professional or registered dietitian before making any significant dietary changes.

The role of vitamins and supplements
While there is no direct link between vitamins, dietary supplements, and psoriasis, many people with psoriasis include vitamins and supplements in their daily lives. Vitamins and minerals are important to consider when managing psoriasis, although it is recommended that you get these from whole foods whenever possible.
Vitamin D, for example, is commonly used in many topical treatments for psoriasis and can be found in beef liver, egg yolk, and Swiss cheese. Vitamin D can also be obtained through sun exposure. Omega-3 fatty acids, which have anti-inflammatory properties, can be obtained from fatty marine fish (such as salmon, sardines, tuna, and mackerel), seafood, vegetable oils (like rapeseed oil, linseed oil, and walnut oil), nuts (especially walnuts), and flaxseed oil.
Some antioxidants that can be introduced in diet therapy for psoriasis include vitamin A, vitamin C, vitamin E, carotenoids, flavonoids, and selenium. These can be obtained from fruits and vegetables, such as high-fiber fruits like blueberries, carrots, and pears, and leafy greens.
It is important to note that while some people swear by the anti-inflammatory properties of turmeric, Dr. Fernandez advises against relying solely on supplements to decrease inflammation due to a lack of scientific evidence regarding their effectiveness in treating psoriasis directly.
In addition to vitamins and supplements, following a well-balanced diet with anti-inflammatory foods can help reduce the frequency and severity of psoriasis flare-ups. This includes reducing or eliminating inflammatory foods, such as excessive alcohol, dairy, added sugars, and gluten, which can worsen inflammation and irritate the gut, increasing the risk of inflammation in the colon and intestines.

Mediterranean diet and psoriasis
Psoriasis is a common chronic inflammatory skin disease that affects 1% to 2% of the general population. It is an autoimmune disease where the body's immune system mistakenly attacks its own healthy cells. This results in the overproduction of skin cells, leading to the formation of red, scaly patches called plaques, which can be itchy and painful. While psoriasis is not caused by diet, there is a significant link between diet and the disease. Certain foods are known to cause inflammation throughout the body, and this widespread irritation can aggravate the symptoms of psoriasis.
The Mediterranean diet is a way of eating that is traditional in the countries surrounding the Mediterranean Sea, including Greece, Italy, Spain, Egypt, Morocco, Libya, Syria, Lebanon, and Israel. It is characterised by a high consumption of plant-based foods, fruits, vegetables, whole grains, beans, legumes, fatty fish, and olive oil. The diet also includes moderate amounts of lean poultry, dairy, and eggs.
The Mediterranean diet has been shown to reduce chronic inflammation and positively impact the risk of metabolic syndrome and cardiovascular events. A study of 35,735 respondents from the French NutriNet-Santé cohort, of whom 3557 had psoriasis, found a statistically significant inverse association between adherence to the Mediterranean diet and the severity of psoriasis. The study concluded that the Mediterranean diet may slow the progression of psoriasis and should be considered as part of the multidisciplinary management of moderate to severe psoriasis.
The anti-inflammatory properties of the Mediterranean diet are attributed to the high content of dietary fibres, antioxidants, and polyphenols. These compounds are known to reduce systemic inflammation and have a positive effect on overall health. Additionally, the Mediterranean diet's emphasis on fatty fish provides a good source of omega-3 fatty acids, which have been shown to have beneficial anti-inflammatory, immunomodulatory, and antioxidant effects in patients with psoriasis.
In conclusion, the Mediterranean diet's anti-inflammatory properties make it a valuable dietary approach for individuals with psoriasis. By reducing chronic inflammation, the Mediterranean diet can help slow the progression of psoriasis and improve overall health outcomes. Patients with psoriasis should consider adopting this dietary pattern in conjunction with their standard medical therapies to manage their condition effectively.

Vegetarian diet and psoriasis
Psoriasis is a chronic inflammatory skin disease. While it is not caused by diet, certain foods are known to cause inflammation throughout the body, which can worsen the symptoms of psoriasis. These include excessive alcohol consumption, dairy products, refined carbohydrates, and foods with lots of added sugars.
A vegetarian diet may help to alleviate the symptoms of psoriasis. This is because a vegetarian diet is typically low in saturated, trans, and arachidonic acid, which can cause inflammation. It is also high in antioxidants and omega-3 fatty acids, which have anti-inflammatory effects. Research has shown that a diet rich in vegetables and fruits can significantly contribute to improving the clinical condition of persons suffering from psoriasis.
A vegetarian diet typically involves giving up meat products and increasing the intake of vegetables, fruits, legumes, nuts, and cereal products. This can result in a more diverse gut bacteria composition, which is beneficial for creating a resilient immune system. Studies have also shown that a diet high in red meat is associated with higher disease severity in people with psoriasis.
In addition to a vegetarian diet, a Mediterranean diet is also recommended for people with psoriasis. This diet is characterized by a high consumption of vegetables, cereals, legumes, fish, fruit, and nuts, and is known to reduce chronic inflammation that contributes to heart disease, type 2 diabetes, cancer, and other conditions.
It is important to note that not all patients with psoriasis react the same way to different foods, and it is always recommended to consult a doctor or a registered dietitian before making any significant dietary changes.
