Read on to know about certain foods that can flare up psoriasis!

Psoriasis is a skin condition that is usually triggered by certain allergens right from stress, bad weather, to certain foods. Here are certain foods that you should consume cautiously while undergoing treatment for psoriasis.

Most of these foods are the ones that can trigger inflammation and create an upheaval in the immune system leading to this skin condition.

Red meat

Eggs and red meat contain a polyunsaturated fatty acid known as arachidonic acid that can result in psoriatic lesions. So, one should avoid red meat, beef, bacon, sausage, processed red meats, and eggs.


People with psoriasis are usually sensitive to gluten, and consuming foods containing gluten can flare up this condition. Foods that one should avoid are wheat and wheat products, barley, rye, malt, sauces and condiments containing gluten, beer, malt beverages, processed foods containing gluten, and baked products containing wheat.

Processed foods

Consuming processed and high-calorie foods can trigger metabolic syndrome and inflammation. So, one should avoid processed meats, canned food products, pre-packaged food products, and other processed foods containing a high quantity of salt, fat, and sugar.


Consuming nightshade plants such as potatoes, tomatoes, peppers, and eggplants has been found to trigger psoriasis. This is because nightshade plants contain solanine, which affects digestions and leads to inflammation.


Alcohol disrupts our immune system and thus results in an auto-immune flare-up that can trigger psoriasis.
