Psoriasis and Diet

Many people with psoriasis have allergies and intolerances to certain foods. The reaction causing foods seem to be similar for most people with this disease. Below is a table of foods with corresponding allergic reaction severity based on my own experience. An allergic reaction refers primarily to itching of psoriasis areas. Allergic reactions occur fairly rapidly, between 10 seconds to 10 minutes after eating a trigger food. In contrast to food allergies, food intolerances cause no initial reactions, but the symptoms appear several hours to several days after eating. Allergic reactions involve the immune system while intolerances don't, at least not immediately. Allergic reactions are simple to track while food intolerances are very difficult to accurately track. The table below shows my experience of allergic reactions to various foods. The ratings are from zero to three, with zero being no reaction, and three resulting in a severe reaction. I've been unable to accurately track food intolerances, so the table is based primarily on food allergies. A few intolerances are listed, but there are undoubtedly more intolerances that have not been tracked. Keep in mind that I'm extremely sensitive to foods. Most people with psoriasis will not even notice a reaction to diet unless eating foods ranked as three on the severity scale below.

The table below shows a few common traits of foods that result in allergic reactions.

Foods that cause allergic reactions Additional Information
1) Sulphites More Info - Sulphites
2) Acidic or acid forming foods More Info - Acids
3) Saturated fats More Info - Fats
4) Foods fermented with yeasts and molds More Info - Yeasts
5) Foods high in histamine content or causing the release of stored histamines More Info - Histamines
6) Laboratory chemicals used as food additives or preservatives More Info - Chemicals
7) Foods containing tannins More Info - Tannins
8) Caramelized sugar More Info - Sugars

The food severity ratings in the table below are based on my bodys reactions to foods and the reactions have been stable over many years. The possible cause listed for the food allergy is just an educated guess and is subject to change. Food rating values of 0 cause no allergic reactions (for me). Foods with rating of 1 cause a mild reaction. A rating of two is moderate. A rating of 3 causes a severe allergic reaction.

Guideline for Reaction Ratings
0) No reaction
1) Mild reaction
2) Moderate reaction
3) Severe reaction
