What You'll Learn
Gluten-free diets may help some people with psoriasis
While there is no diet that can cure psoriasis, eating healthily may lessen the severity of symptoms and lower the likelihood of developing comorbidities. Research suggests that some foods, especially highly processed ones, put your body's defence mechanisms into overdrive, triggering an inflammatory response. This can make psoriasis symptoms worse.
Gluten-free diets have gained attention in recent years, and some people with psoriasis may benefit from them. Gluten is a complex protein found in wheat, barley, and rye, as well as their derivatives. Following a gluten-free diet requires careful reading of labels, as gluten can be present in hidden sources.
Some studies have shown that a gluten-free diet can help reduce psoriasis symptoms, especially in individuals with gluten sensitivity or celiac disease. According to the National Psoriasis Foundation, up to 25% of people with psoriasis have a sensitivity to gluten. Experts estimate that up to 2 million people in the U.S. may suffer from a gluten allergy. However, not everyone with psoriasis will react the same way to gluten, and more research is needed to establish a clear link.
If you are considering a gluten-free diet to help manage your psoriasis, it is recommended that you remain completely gluten-free for at least three months. During this time, be sure to remove all sources of gluten from your diet. After the three-month period, if you are unsure whether eliminating gluten has benefited you, try gradually adding it back into your diet. Monitor for any increased psoriasis symptoms, such as skin changes, itching, or joint pain. If you don't notice any negative effects, you may choose to add gluten back into your diet permanently.
It is important to note that a gluten-free diet is very restrictive and should not be undertaken unnecessarily. Discuss any dietary modifications with your healthcare provider before making adjustments. They can guide you on the best approach and help determine if a gluten-free diet is right for you.

Dairy products can cause inflammation, making psoriasis worse
People with psoriasis are often advised to follow an anti-inflammatory diet, which typically includes fruits, vegetables, lean proteins, whole grains, and healthy fats. While dairy products are not inherently inflammatory, they can be problematic for individuals with lactose intolerance or cow's milk allergy.
Dairy products, particularly those containing cow's milk, can cause inflammation in individuals with lactose intolerance or a cow's milk allergy. Lactose intolerance is the inability to digest lactose, a sugar found in milk, due to insufficient levels of the digestive enzyme lactase. This can lead to chronic gastrointestinal irritation, contributing to inflammation in the body. Additionally, dairy products tend to be high in fat, which can also trigger inflammation.
For some people with psoriasis, cutting dairy from their diet has led to improvements in their symptoms. However, it is important to note that the impact of dairy on psoriasis is highly individualised. While some people may notice a positive difference when eliminating dairy, others may not experience any changes. Research has shown that dairy products can have anti-inflammatory effects for most people, except for those with a cow's milk allergy.
If you have psoriasis and suspect that dairy may be triggering flare-ups, it is recommended to consult a healthcare professional before making any dietary changes. Keeping a food journal or taking progress photos can also help identify potential triggers and track the impact of dietary modifications. It is important to note that extreme diets or fasting are not recommended for managing psoriasis, as they may be ineffective or even dangerous.
Overall, while dairy products can cause inflammation in certain individuals, the link between dairy and psoriasis is not universally established. The impact of dairy on psoriasis varies from person to person, and personal experiences and observations are crucial in determining dietary choices. Consulting with a healthcare provider or registered dietitian can help tailor dietary recommendations to manage psoriasis effectively.

Obesity increases the risk of psoriasis and can worsen symptoms
While psoriasis is not caused by diet, certain foods are known to cause inflammation throughout the body, which can worsen symptoms. Obesity is a well-known risk factor for psoriasis, and weight loss can help ease symptoms.
Research has shown a statistically significant difference in psoriasis frequency across different BMI categories. The prevalence of psoriasis was 9.5% in patients with normal weight, 11.9% in overweight patients, 14.2% in grade I obesity, and 17.4% in patients with grades II–III obesity. Obesity is associated with moderate and severe psoriasis.
Obesity and a high-fat diet are linked to intestinal dysbiosis, leading to decreased intraluminal short-chain fatty acid production and local inflammation. This inflammation can increase the risk of autoimmune conditions like psoriasis. Fat cells release inflammatory chemicals called cytokines, which may play a role in psoriasis symptoms. Losing weight can help lower inflammation in the body and lessen psoriasis symptoms.
A gluten-free diet may also help reduce psoriasis symptoms, as gluten can cause problems for some people. However, it is important to note that not everyone reacts the same way to gluten, and a gluten-free diet is a major commitment. It is recommended to discuss any dietary modifications with a healthcare provider before making adjustments.
Overall, while obesity increases the risk of psoriasis and can worsen symptoms, a healthy diet and weight loss can help to ease symptoms and reduce associated health complications.

Alcohol can worsen psoriasis symptoms, even in moderate amounts
While there is no cure for psoriasis, certain dietary changes may help manage the condition. Alcohol consumption, for instance, has been linked to worsened psoriasis symptoms, even in moderate amounts.
Psoriasis is a chronic inflammatory skin disease that can be triggered or exacerbated by various factors, including alcohol intake. Alcohol can negatively impact the body's inflammatory processes, potentially worsening psoriasis symptoms. Research suggests that people with psoriasis are twice as likely to develop nonalcoholic fatty liver disease (NAFLD), which can progress into serious liver disease. Alcohol consumption can also increase the harmful side effects of some psoriasis medications, particularly in pregnant individuals.
Several studies have found a correlation between alcohol consumption and an increased risk of developing psoriasis or experiencing flares. The Nurses' Health Study, for example, linked non-light beer intake in a cohort of US nurses to a higher risk of psoriasis. Another study of 150 outpatients found that alcohol consumption, along with obesity, tobacco use, and smoking, negatively impacted the therapeutic outcome of conventional psoriasis therapy.
While the specific cause of psoriasis remains unknown, alcohol has been identified as a potential trigger for flares. Experts recommend that individuals with psoriasis limit or exclude alcohol from their diets to manage their symptoms effectively. Decreasing alcohol intake may also reduce the risk of NAFLD and improve treatment outcomes.
It is important to note that everyone's experience with psoriasis is unique, and triggers may vary. If you suspect that alcohol is triggering your psoriasis symptoms, it is advisable to consult a healthcare professional, who can provide personalized advice and guidance on managing your condition.

A vegan diet may benefit people with psoriasis
Psoriasis is a chronic autoimmune skin disorder that causes red, scaly and itchy patches on the skin. While there is no specific diet that can cure the disease, certain foods are known to cause inflammation throughout the body, which can worsen the symptoms of psoriasis.
A vegan diet, which is devoid of all animal products, may help reduce inflammation and benefit people with psoriasis. This is because a vegan diet eliminates foods that are known to trigger flare-ups, such as red meat, dairy, and eggs, which contain arachidonic acid, a fatty acid that can create chemicals causing inflammation. Additionally, a vegan diet can increase the diversity of gut bacteria, which is beneficial for creating a resilient immune system.
A plant-based diet can also help reduce inflammation by providing healthy fiber and anti-inflammatory compounds found in whole foods. Studies have shown that people with psoriasis who consumed more vegetables experienced lower disease severity. Loading up on fruits, vegetables, whole grains, legumes, and healthy oils can be an effective way to reduce flare-ups and improve overall health.
It is important to note that a vegan diet may not be suitable for everyone with psoriasis, and individual results may vary. Some people with psoriasis have found success in reducing gluten or adopting a Mediterranean or paleo diet, which emphasizes whole foods and anti-inflammatory compounds.
Before making any dietary changes, it is recommended to consult with a healthcare provider or dermatologist to determine the best course of action for managing psoriasis symptoms.
