Psoriasis is a chronic autoimmune skin condition in which the body produces skin cells too quickly. This leads to red, scaly patches on the skin’s surface, known as plaques, which can be itchy or painful.
In some cases, psoriasis is accompanied by psoriatic arthritis, a form of joint inflammation.
While food isn’t a direct cause of psoriasis, diet can influence the severity of symptoms. Certain foods may trigger or worsen inflammation, while others may help reduce it.
For instance, foods high in sugar, fried items, and processed meats can contribute to inflammation in the body.
Over time, excessive consumption of these foods may lead to weight gain, which can worsen psoriasis symptoms.
Recommended Foods
To help ease symptoms, here are some types of food you should include more often in your diet:
1. Eat More Fish
Fatty fish, such as salmon, sardines, and mackerel, are rich in omega-3 fatty acids, which are known for their anti-inflammatory properties and immune-boosting benefits.
One study found that individuals who consumed approximately 175 grams of fatty fish per week experienced an improvement in their psoriasis symptoms.
If you get tired of fish, consider other healthy protein alternatives, such as tofu, tempeh, or other plant-based proteins.
2. Colorful Fruits and Vegetables
Fruits and vegetables are rich in antioxidants, fiber, and vitamins that help the body combat inflammation. Great options for people with psoriasis include:
- Berries, cherries, and apples: Packed with polyphenols, powerful antioxidants that help reduce inflammation.
- Citrus fruits and melons are high in vitamin C, which supports immune health.
- Pineapple: Contains bromelain, an enzyme with anti-inflammatory effects.
- Leafy greens like kale, spinach, arugula, and mustard greens: Low in calories, high in fiber, and versatile in meals.
Remember: the more colors on your plate, the more complete your nutrient intake will be.
3. Healthy Fats and Whole Grains
Legumes (like lentils and chickpeas), seeds, and olive oil are sources of healthy fats that can benefit people with psoriasis. These foods are also rich in protein and antioxidants, and they help reduce inflammation and support a healthy weight.
Here are some easy swaps:
- Replace ground meat with kidney beans in chilli or tacos.
- Add hummus or nut butter to sandwiches.
- Choose whole grain bread, pasta, and cereal instead of refined white versions.
Maintain a Healthy Weight
Psoriasis tends to worsen in people who are overweight or obese. Maintaining a healthy weight can reduce the frequency and severity of flare-ups. Some ways to support this include:
- Reducing daily calorie intake
- Controlling portion sizes
- Staying active and exercising regularly
A Healthy Lifestyle Matters Too
Eating well is just one part of managing psoriasis. For better results, combine it with:
- Getting enough sleep each night
- Staying physically active to boost immunity and manage weight
- Managing stress, since stress can trigger flare-ups
There’s no one-size-fits-all diet that can cure psoriasis, but wise food choices can make a big difference.
Focus on anti-inflammatory foods and limit processed items to support your overall health with good habits.
