Psoriasis Diet Basics
Psoriasis appears in all sorts of ways, from a scaly, white plaque that builds up on the skin, to showing up as abnormal changes in nails, to a type of arthritis that accompanies skin or nail psoriasis. It’s a chronic condition, so there’s no getting rid of it for good. And it comes and goes, sometimes seemingly at random. That can make it a hugely frustrating condition to treat, as you never know when or how badly it might rear its ugly head.
The basics of a diet for psoriasis aren’t the same for everyone. That said, psoriasis is linked with some known triggers. And while no onewantsto hear that their favorite food might cause a flare-up, it’s also helpful to feel like you can exert some control over your condition via what you put on your plate. Foods related to inflammation can be common triggers for many. Here are some foods to avoid as well as foods to include on a psoriasis diet.
Foods to Avoid with Psoriasis
Alcohol
We’ll start with the bad news first: althoughthe research isn’t conclusiveabout whether alcohol consumption exacerbates psoriasis, alcoholmay disrupt your immune system, and thus, trigger a flare-up—particularly if you’re older and have been dealing with psoriasis for a long time. Go easy on alcohol, and particularly consider staying away frombeer, as the grains and starches it’s made with may be a factor in psoriasis: light beers (made with less starch), wine and liquor don’t show this association.
Gluten
The link between beer and a psoriasis flare-up is gluten. Non-light beer is typically made using fermented barley or other starches, which contain gluten. As you may already know,celiac disease—like psoriasis—is also an autoimmune response. So it makes sense that people with psoriasis may also have gluten sensitivity, and could benefit from cutting wheat, rye, barley, malt and other gluten-containing foods from their diets. Sounds grim, but theresearch suggeststhat following a gluten-free diet can really help avoid a run-in with your psoriasis.
Nightshades
The name alone sounds ominous, and members of the family of plants known as “nightshades” will indeed throw shade on your psoriasis health. Potatoes, tomatoes, peppers, eggplant, tomatillos and tobacco (more on that later) are all members of the nightshade family—and unfortunately, all are linked to psoriasis flare-ups.Researchers thinkthat nightshades may aggravate the intestinal lining and exacerbate immune-related disorders.

Tobacco
This is kind of a no-brainer. Tobaccohas been linkedto many unfavorable health outcomes, and yes—because it’s a member of the nightshade family, it’s also linked with psoriasis.
Sugar
You saw that one coming, right? Sad, but true. Like tobacco, sugar doesn’t have a great reputation in the nutrition world, and junk foods are strongly associated with psoriasis episodes. According toresearchpublished inDermatologic Therapy,50% of trial participants reported a positive skin response when they cut out junk foods like candy, pastries, chocolate, sweets—and also french fries and potato chips (remember: potatoes are nightshades).
Processed Foods
Technically, it’s “white flour products” that are the culprits here. But since most highly processed foods (such as cookies, crackers and convenience foods) include white flour—and often, other triggers like sugar and of course, gluten—it’s often easiest to just swear off of them altogether. Plus, there’sa connection between obesity and psoriasis, so if skipping the processed foods (which are often high in low-quality calories) leads to a lower BMI, it’s a win-win for your healthandyour psoriasis.

Fruits and Vegetables
Antioxidants are key to anti-inflammatory eating, as they protect your cells from the effects of free radicals and reduce the oxidative stress that causes inflammation. Fruits and vegetables are high in antioxidants, have complex carbohydrates with high fiber content (good for the gut microbiome!) and contain lots of good-for-you vitamins and nutrients to keepinflammation down and psoriasis in check. Try the following:
Turmeric

Turmeric is the sunshine-hued spice that gives curry its vibrant color. It has a pungent, earthy flavor that most people either love or hate—and a polyphenol called curcumin, which haspowerful anti-inflammatory properties.Add turmeric to your morning eggs, blend it into hummus, drink it in tea, whip it into a smoothie or sprinkle it over roasted veggies (add black pepper to increase absorption). And if you truly can’t stand the taste, you can always pop a curcumin supplement.
Fatty Fish and Heart-Healthy Oils

Fish like salmon, lake trout, mackerel, tuna, cod and sardines are high in good-for-you fats called omega-3s. Omega-3s haveanti-inflammatory propertiesthat can help keep psoriasis in check. Aim for two servings of fish per week (a serving is 3.5 ounces cooked, or 1/3 cup flaked) for anti-inflammatory benefits, as well as a host of otherheart-healthy benefits. Likewise, you can obtain similar benefits from heart-healthy oils, including olive oil and coconut oil.
