Does diet have an impact on your psoriatic arthritis?

We know everyone is different, but I'm curious to read more about your personal experiences. Have you found any diets, such as anti-inflammatory, gluten-free, or low carb, to have any effect on your PsA? How has it been following such a diet?

Are there any foods you avoid because they trigger your PsA? Please share your experiences with us!

  1. I think so.
    A plant rich diet with quality meat and complex carbs works best for me, wine in moderation as alcohol can be a negative (a very dry, occasional glass!).
    Processed foods, fatty food, sugars - definitely a negative impact. I am not sure there is a 'magic diet' just a conscious diet - along with daily exercise/movement, stretching, rest, and attempt at a good night's sleep !
    FWIW, I have a sensitive stomach too and that is a major drive in how I eat as well.

    1. Hi . I am glad you found a way of eating that helps. I think you're right -- that there is no one diet for everyone. It seems dietary changes impact everyone differently. Wishing you the best! - Lori (Team Member)

    2. I did get a book on psoriasis nutrition from the library. Apparently it worked for those who followed it. It was too rigid for me. Quality meat does not mean angus beef (though to many people it does) but rather grass fed grass finished organic ideally. However with ones budget compromise is required. Sounds like northern elf has the right approach to the problem.

  2. I'm interested in this question, but have reached very few conclusions, other than obvious ones. When I was feeling joint pain, but before I was diagnosed, I made an effort to cut out / down certain foods, such as butter, cream, processed meat, sugar etc. I wasn't overweight (not seriously anyway) but I thought losing even 1-2 kg would at least not do any harm.


    Since diagnosis and being put on methotrexate, I've also pretty much ditched alcohol and try to eat foods that supply folic acid (in addition to taking prescribed supplements). I also keep a diary with the idea of monitoring food, exercise, movement and pain levels. This is a useful thing to do for all sorts of reasons, but it hasn't helped me see any correlation between certain foods and pain levels.


    I did read that 'nightshade' vegetables like aubergines (egg-plant), peppers or even tomatoes could trigger inflammation, but they don't seem to affect me one way or the other. Which is good, as I love aubergines especially.


    I really don't think I'd want to do one of those diets where you cut everything with potential to cause inflammation then try to build things back in one by one ; at present there doesn't seem to be a compelling reason to go that way.


    So yes, agree with most of what's been said already.

    1. I tried as well cutting out or cutting down on portions of food. I could not tell any difference in my pain level. It is great that it works for some people. After all we are all different and what works for one might not work for another. As always thanks for sharing. Vickie W., Team Member

  3. no nightshades

    1. you're definitely not alone! I know several of our community members have found that nightshades impact their PsA symptoms. You might appreciate this article from one of our health leaders about PsA and nightshades, https://plaquepsoriasis.com/living/what-are-nightshades. Was this something that took awhile for you to notice and cut out? -- Warmly, Christine (Team Member)

  4. yes

    1. Hi again, ! You're not alone in finding that diet affects your PsA. Is there a particular diet that you find helpful, or certain foods that you try to avoid? Warmly, -Catherine, Community Moderator

    2. Hello , Do you have one that effects you more then the other. I grew up on a farm, so we had them all. Back in the 60's we never heard of nightshades. The only thing that effected me was any type of tomatoes. While everyone else had sauce on there spagetti - I had butter. Have you had to give up anything entirely? If so, what was it. We would like to hear from you. Diane (Team Member)
