Currently, there is no strong research to suggest that specific foods or diets help to improve PsA or the accompanying fatigue. However, this doesn’t mean that changes to your diet won’t help; many people with psoriatic disease believe diet is relevant for improving their symptoms. However, it won’t work for everyone and each person may differ in which foods they do or do not respond well to. It could help to:
Choose foods that help fight inflammation.
Diets which potentially combat inflammation include those with high amounts of:
- Monounsaturated fats (such as from avocado, nuts, olive oil, sunflower oil and peanut butter) and omega-3 fatty acids (found in fatty cold-water fish, like salmon, mackerel and tuna, nuts and plant oils)
- Fruits, vegetables, raw nuts and whole grains
- Soluble fibre (which gives stool bulk, found in oats, beans, bran, barley and citrus fruits) and insoluble fibre (helps speed up digestion, found in whole-wheat flour, nuts, beans, potatoes and green vegetables)
- Polyphenols (antioxidants - contained in tea, cocoa, berries, fruits and more)
Avoid foods which could worsen inflammation.
Diets which potentially promote inflammation include those with:
- High fat content (including ‘artificial’ trans fats, found in many fried and baked goods - ‘junk food’ - including fried chicken, chips, cakes - along with whole milk, margarine and other products)
- High glycemic index (foods that release sugar very quickly)
- High amounts of refined grains or minimally processed whole grains (such as white flour, white bread and white rice)
- Sugar-sweetened carbonated and noncarbonated beverages
Discuss supplements which may fight inflammation with your healthcare professional.
It is important to discuss any supplements you are considering using with your healthcare professional, so they can advise you on whether it would be suitable to take them or not.
