Diet and Psoriasis

Continued

Two specific things you may want to check on are:

Vitamin D : A study from Spain found that people with psoriasis had lower levels of vitamin D. This vitamin helps keep your immune system working correctly. Ask your doctor to check your vitamin D levels, McCusker says. You may need a prescription-strength supplement.

Fish oil : This can help your body tame inflammation. "I don't think fish oil can turn off psoriasis," McCusker says, but "people who take it tend to be a little less itchy, and their plaques tend to be a little less red." You can also get the omega-3s that are in fish oil by eating fish such as salmon, tuna, or mackerel a couple of times a week.

Small studies also found that fish oil may reduce some side effects of medicines used to treat psoriasis, such as:

  • High triglycerides from a type of drug known as retinoids, such as Soriatane (acitretin ), Aceret, Acetec, and Zoratame
  • Kidney problems from cyclosporine, such as Neoral, Sandimmune, Restasis, Gengraf Capsules, and Gengraf Oral Solution
