Then there are also foods that can cause flare-ups.

If you are suffering from psoriasis and you want to keep those flare-ups at bay, keep on reading. Below you will come across certain foods that you should avoid at all costs.

Got family members and friends who also suffer from psoriasis? Make sure that you share this article on your various social media sites to that they may also get acquainted with foods that they should dodge to keep flare-ups from striking.

Red Meat

Because red meat is packed with saturated fat and bad cholesterol, people who are suffering from heart disease are encouraged to considerably limit their intake of those.

As someone who has psoriasis, it is a good idea for you to also steer clear of red meat — certain compounds in red meat can cause inflammation, and inflammation can trigger psoriasis flare-ups, experts say.


It’s true that milk and various dairy products supply your body with protein, calcium, potassium, vitamin B12 and vitamin D, which only means that they’re great for keeping you healthy.

Unfortunately, you have no choice but to steer clear of them if you have psoriasis. Just like red meat, dairy can cause inflammation and thus lead to a flare-up.

Junk Food

Definitely, it can be disheartening to know that you have no choice but to avoid dairy and miss out on the health perks they offer. However, you should have no remorse turning your back on junk food that can easily cause a flare-up.

There are simply lots of things in junk food that make its consumption extremely bad for you whether or not you have psoriasis — from trans fat to refined sugar.


Health experts agree that moderate intake of alcohol in fact comes with a number of benefits. But if you are a psoriasis sufferer, moderate and even light intake of alcoholic drinks is bad for you.

That’s because alcohol causes your blood vessels to widen, thus allowing some of your immune cells to get to your skin and spring into action even when there’s nothing for them to attack.

Citrus Fruits

Some people who suffer from psoriasis encounter a flare-up after consuming lemons, oranges and other citrus fruits. However, there are some with psoriasis who do not encounter a flare-up after having the said types of fruits.

If citrus fruits do not bug you with flare-ups, then feel free to add them to your diet on a regular basis. If problems strike after consuming them, then you’re better off avoiding citrus fruits.


Just like citrus fruits, nightshades such as eggplants, tomatoes, bell peppers and white potatoes are known to cause flare-ups in some — there are certain compounds in nightshades that can trigger inflammation within.

Scientists say that a chemical called solanine present in nightshades can cause pain in some. So if you end up experiencing pain after consuming something that belongs to the nightshade family of plants, it’s time to watch what you eat.


Individuals who suffer from celiac disease or gluten intolerance are strongly encouraged to avoid wheat, rye, barley and anything that contains gluten in order to dodge symptoms that range from abdominal pain to depression.

Some people with psoriasis report of seeing improvements with their skin condition after going on a gluten-free diet. This is true whether or not they have celiac disease or gluten intolerance.


There are some condiments that are known to trigger inflammation and ultimately a flare-up. This is most especially true for those that contain certain ingredients such as vinegar, mayonnaise, pimiento and curry. 

It’s true that condiments make food more flavorful. But if they cause flare-ups, it’s a good idea for you to eliminate them from your diet to keep psoriasis outbursts from happening.
