These convenient frozen and canned staples are packed with nutrients that help reduce inflammation and support gut health and skin wellness for people living with psoriasis 

• KEY POINTS
• Certain nutrients and dietary patterns help psoriasis by reducing inflammation.
• Canned and frozen foods like sardines, berries, lentils and spinach are great options.
• Reducing stress, eating consistently and moving your body also help.

Did you know that psoriasis affects more than just the skin? It’s a chronic condition that’s closely connected to overall immune health and inflammation throughout the body. While diet doesn’t cause or cure psoriasis, research suggests that certain eating patterns may help reduce inflammation and potentially reduce the severity of a flare-up. Experts often recommend focusing on nutrient-dense, anti-inflammatory foods like colourful fruits and vegetables, legumes, whole grains, healthy fats and omega-3-rich fish.

Eating a nutrient-dense diet can sometimes feel expensive or difficult to maintain, especially when fresh produce and healthy ingredients spoil quickly and can require extra preparation. Fortunately, healthy eating doesn’t require everything to be fresh. Convenience foods like frozen and canned can be incredibly convenient, budget-friendly and nutritious additions to a psoriasis-supportive eating pattern. According to Danielle Smiley, RDN, frozen and canned foods can be excellent tools for supporting consistency, affordability and nourishment. “If healthy foods are easier to access and prepare, people are more likely to eat them regularly,” she notes.

Here are a few of the best frozen and canned foods that dietitians recommend stocking up on if you have psoriasis.

1. Canned Sardines

 “Canned sardines are a great option for people with psoriasis, as they’re packed with omega-3 fatty acids, which help minimize the inflammatory response associated with psoriasis,” says Amy Brownstein, M.S., RDN. Omega-3 fatty acids, particularly EPA and DHA, help reduce inflammation by decreasing the production of inflammatory compounds in the body. In psoriasis, the immune system becomes overactive, which triggers inflammatory pathways that accelerate skin cell turnover and contribute to redness, itching and plaque formation.

According to Brownstein, research has linked Mediterranean-style eating patterns—which emphasize fatty fish, olive oil, fruits, vegetables and legumes—with lower psoriasis severity and reduced inflammation. “These foods provide antioxidants, fibre, polyphenols and healthy fats that may support a calmer inflammatory response,” adds Brownstein.

2. Frozen Berries

Frozen berries are loaded with antioxidants, including anthocyanins and vitamin C, which may help to combat oxidative stress linked to inflammation. Since berries are frozen shortly after harvest, they retain many of their nutrients and are available year-round, making them very convenient.

In addition to their antioxidant content, berries provide fibre. “Fibre-rich eating patterns also support gut health, which is important because emerging research suggests a strong gut-skin connection in inflammatory skin conditions like psoriasis,” says Samaria Garrett, M.S., RDN.

Fibre acts as a food source for beneficial gut bacteria. When these bacteria ferment fibre, they produce short-chain fatty acids, which may help strengthen the gut lining, regulate immune function and reduce systemic inflammation. Supporting gut health through consistent intake of fibre-rich foods may help support skin health and overall psoriasis management.

3. Canned Lentils

Canned lentils are an affordable, versatile staple that provides plant-based protein, fibre, antioxidants and several other important nutrients. Lentils support gut health and help regulate blood sugar levels, both of which may influence inflammation.

Brownstein notes that canned lentils deliver vitamin E, which may help protect against cellular stress and support the skin barrier. In inflammatory conditions like psoriasis, oxidative stress is believed to contribute to increased inflammation, skin irritation and accelerated skin cell turnover. That’s why nutrients that support skin integrity, like vitamin E, are especially important. The skin barrier helps retain moisture, protects against environmental irritants and defends against bacteria and allergens. When the barrier becomes compromised, skin may become drier, more irritated and more prone to flare-ups. Vitamin E may help to support the skin barrier by protecting skin cell membranes from damage and helping maintain skin hydration and resilience.

4. Frozen Spinach

Frozen vegetables like spinach are a convenient way to boost your intake of vitamins, minerals and antioxidants without worrying about food waste. Smiley recommends frozen spinach because it contains nutrients associated with inflammation support and overall wellness. Spinach is rich in antioxidants, including vitamin C, beta-carotene, and flavonoids, which help combat oxidative stress, a process linked to chronic inflammation and inflammatory skin conditions such as psoriasis.

Frozen spinach is also a good source of vitamin A, which is a nutrient that plays an important role in skin cell growth and repair. Since psoriasis involves rapid skin cell turnover, nutrients that support healthy skin, such as vitamin A, may be especially beneficial. Additionally, spinach contains vitamin K, folate, magnesium and iron, which support circulation, immune function and overall cellular health.

Frozen vegetables can make it easier to consistently include produce in meals, especially during busy weeks. “One thing I often say is: nourishment that is accessible and repeatable will almost always outperform nutrition perfectionism,” says Smiley.

Other Tips for Psoriasis

While nutrition can play a supportive role, managing psoriasis involves more than just food. Experts recommend taking an inclusive approach to support overall inflammatory health.

• Prioritize stress management: Chronic stress may influence inflammation, sleep quality and psoriasis flare severity. Brownstein recommends practices like stress management, exercise and quality sleep to help reduce inflammation.
• Focus on consistent meals: Smiley encourages eating regular, balanced meals rather than cycling between restriction and overeating, which can affect blood sugar and energy levels.
• Get enough movement: Regular physical activity can support immune health, reduce stress and promote overall recovery. Even small lifestyle shifts may positively affect quality of life and inflammation levels.

Our Expert Take

Psoriasis is a complex inflammatory condition, and while there’s no single food that can cure it, research suggests that anti-inflammatory eating patterns rich in omega-3 fats, fibre, antioxidants and colourful plant foods may help support overall inflammatory balance and skin health.

Convenient staples like canned sardines, lentils, frozen berries and frozen spinach can make it easier to nourish your body consistently and conveniently without relying solely on fresh ingredients. Combined with healthy lifestyle habits, these foods may help support overall wellness and quality of life for people living with psoriasis.
