Diet and Psoriasis: Foods to Eat and Avoid

Psoriasis is a chronic autoimmune disorder in which the immune system mistakenly attacks healthy skin cells, leading to red, scaly patches that can be itchy and sometimes uncomfortable. This lifelong condition affects not only the skin but can also impact emotional and mental well-being.

Research has shown that what we eat can have a significant influence on psoriasis. Diet plays a role in inflammation, a key factor in psoriasis, and overall health, which can either help manage symptoms or potentially trigger flare-ups. The purpose of this article is to guide you through the types of foods that may help support psoriasis management and those that might exacerbate symptoms.

Understanding the Role of Diet in Psoriasis

Inflammation is a major player in psoriasis, and what you eat can directly impact your body’s inflammatory response. Certain foods can increase inflammation, making psoriasis symptoms more noticeable, while others have anti-inflammatory properties that may help support skin health. It’s all about finding the right balance and making choices that support your body’s needs.

There’s a strong link between your gut and your skin, often referred to as the gut-skin axis. A healthy gut microbiome—a diverse community of bacteria in your digestive system—plays a critical role in managing inflammation and overall skin health. 

What you eat influences the health of your gut, which in turn can affect your psoriasis. By nurturing your gut through your diet, you’re also taking care of your skin.

Research suggests that diet can influence the severity and frequency of psoriasis flare-ups. While individual results may vary, many people find that certain dietary changes can help them better manage their symptoms. Paying attention to your body’s reactions to different foods can be a valuable part of your psoriasis management plan.

Foods to Eat for Managing Psoriasis

Making informed dietary choices can help manage psoriasis symptoms and improve overall health. Here are some foods that are beneficial for individuals with psoriasis:

1. Omega-3 Fatty Acids

• Benefits: Omega-3s have strong anti-inflammatory properties, which may help support the management of psoriasis symptoms by calming the body’s immune response.
• Sources: Fatty fish like salmon, mackerel, and sardines, as well as flaxseeds, chia seeds, and walnuts.

2. Antioxidant-Rich Fruits and Vegetables

• Benefits: Antioxidant-rich foods help combat oxidative stress, support immune health, and may reduce inflammation.
• Sources: Berries, leafy greens, bell peppers, tomatoes, and carrots are great options.

3. Whole Grains

• Benefits: Whole grains provide essential fiber and nutrients that support gut health and may help manage inflammation.
• Sources: Oats, quinoa, brown rice, and whole wheat.

4. Healthy Fats

• Benefits: Healthy fats are crucial for overall health and may help support the management of inflammation.
• Sources: Olive oil, avocados, nuts, and seeds.

5. Probiotics and Fermented Foods

• Benefits: Probiotics promote a healthy gut microbiome, which may help support better skin health.
• Sources: Yogurt, kefir, sauerkraut, kimchi, and kombucha.

6. Lean Protein

• Benefits: Lean proteins provide essential nutrients without contributing to inflammation, supporting overall body health.
• Sources: Chicken, turkey, tofu, and legumes.

Foods to Avoid for Psoriasis Management

While some foods can help manage psoriasis, others can make symptoms more noticeable by increasing inflammation or triggering flare-ups. Here are some foods that are best minimized or avoided to help manage psoriasis:

1. Processed and Refined Foods

Processed and refined foods often contain high sugars, unhealthy fats, and preservatives, which can increase inflammation levels in the body. These foods also contribute to weight gain, another factor that can impact psoriasis symptoms.

Examples: White bread, pastries, fast food, and sugary snacks.

2. Red Meat and Processed Meats

Red and processed meats are high in saturated fats and certain compounds that can trigger inflammation. Regular consumption of these meats has been linked to increased inflammation, which can affect psoriasis symptoms.

Examples: Beef, pork, bacon, and sausages.

3. Dairy Products

While not everyone with psoriasis is sensitive to dairy, some individuals find that dairy products can trigger inflammation or worsen symptoms. The exact cause isn’t clear, but it may be related to the proteins or fats found in dairy.

Examples: Milk, cheese, butter, and cream.

4. Nightshade Vegetables

Nightshades contain solanine, a compound that can cause inflammation in some people, potentially affecting psoriasis. While not everyone will react to these vegetables, it’s worth monitoring if you notice flare-ups after consuming them.

Examples: Tomatoes, potatoes, eggplant, and peppers.

5. Alcohol

Alcohol can interfere with your immune system and has been shown to trigger flare-ups in many people with psoriasis. It can also reduce the effectiveness of some psoriasis management strategies, making it harder to manage symptoms.

Examples: Beer, wine, and spirits.

6. Gluten-Containing Foods

For individuals with gluten sensitivity or celiac disease, consuming gluten can affect psoriasis symptoms. Even if you don’t have a diagnosed sensitivity, some people with psoriasis report improvements when avoiding gluten.

Examples: Wheat, barley, rye, bread, and pasta.

Creating a Psoriasis-Friendly Diet

Building a diet that supports your journey with psoriasis involves more than just avoiding certain foods; it’s about embracing a balanced, nutritious approach that can help support overall health.

Meal Planning Tips

Start by planning meals that incorporate anti-inflammatory foods like fatty fish, leafy greens, whole grains, and healthy fats. Preparing meals in advance can help you stay on track and make it easier to avoid processed and trigger foods. Incorporate a variety of colorful fruits and vegetables, lean proteins, and whole foods into your daily diet, aiming for meals that are not only nutritious but also enjoyable.

Importance of Balanced Nutrition

Maintaining a balanced diet is essential for managing psoriasis. A diet rich in essential nutrients supports your immune system and overall body function, which is particularly important when dealing with a chronic condition like psoriasis. Focus on a mix of proteins, healthy fats, carbohydrates, vitamins, and minerals to ensure your body gets everything it needs.

Hydration

Staying hydrated is vital for skin health and overall well-being. Drinking enough water helps keep your skin hydrated from the inside out, which may help alleviate dryness and discomfort associated with psoriasis. Aim to drink plenty of water throughout the day, and consider herbal teas or infused water as flavorful alternatives.

Moderation and Listening to Your Body

While guidelines can be helpful, everyone’s experience with psoriasis is unique. It’s important to pay attention to how your body responds to different foods. What works for one person might not work for another, so listen to your body and adjust your diet accordingly. Moderation is key; you don’t have to eliminate your favorite foods entirely, but focus on balancing them within a healthy, varied diet.

Supplements and Psoriasis

Supplements can be a helpful addition to your diet, especially when certain nutrients are hard to obtain through food alone. However, before starting any new supplements, it’s essential to discuss your options with a healthcare provider. 

They can help determine which supplements are appropriate for your specific needs, ensure they don’t interfere with any medications you’re taking, and guide you on proper dosages. Here are some supplements that may benefit those with psoriasis:

Omega-3 Supplements

Omega-3 fatty acids are known for their anti-inflammatory properties, which may be beneficial for psoriasis. For individuals who don’t get enough omega-3s from their diet, such as those who don’t consume fatty fish regularly, supplements can help bridge the gap and potentially support inflammation management.

Vitamin D

Vitamin D plays a critical role in skin health and immune function, making it especially relevant for those with psoriasis. People with psoriasis often have lower levels of vitamin D, and supplementation can help support skin health and may contribute to symptom management.

Probiotics

Probiotics are beneficial bacteria that support gut health, which is closely linked to immune function and inflammation. By promoting a healthy gut microbiome, probiotics may help manage psoriasis symptoms, although more research is needed to fully understand their impact.

Turmeric/Curcumin

Turmeric and its active compound curcumin, are celebrated for their strong anti-inflammatory properties. It may help support the management of psoriasis symptoms by calming inflammation in the body. Adding turmeric to your diet or taking it as a supplement could offer some relief, but it’s best to consult a healthcare provider first.

Managing Psoriasis Through Lifestyle Changes

Living with psoriasis involves more than just dietary adjustments; it also requires making thoughtful lifestyle changes to help manage symptoms and improve overall well-being. Here are some key lifestyle changes to consider:

• Stress Management: Stress is a known trigger for psoriasis flare-ups, so managing stress effectively is key. Techniques such as mindfulness, meditation, deep breathing exercises, or even regular hobbies can help reduce stress levels and, in turn, may minimize psoriasis symptoms.

• Regular Exercise: Physical activity isn’t just good for overall health—it also helps reduce inflammation and improve mood, both of which can positively impact psoriasis. Regular exercise can also aid in weight management, which is important since excess weight can affect psoriasis symptoms.

• Sleep Hygiene: Getting adequate sleep is important for everyone, especially those managing chronic conditions like psoriasis. Quality sleep supports immune function, reduces stress, and promotes overall skin health. Establishing good sleep hygiene, such as maintaining a regular sleep schedule and creating a restful environment, can make a significant difference.

• Avoiding Smoking: Smoking can affect psoriasis and reduce the effectiveness of management strategies. Quitting smoking is one of the best lifestyle changes you can make for your health, as it not only benefits your skin but also your overall well-being. If quitting feels overwhelming, seek support from healthcare providers or smoking cessation programs.
