Plant-Based Diets for Psoriasis

Today's Blog--

Plant-based diets appear to decrease inflammation via a variety of mechanisms, including boosting our adrenal gland function. Glucocorticoids are circulating steroid hormones produced by our adrenal glands that suppress inflammation and also help our kidneys excrete potassium. When we eat a lot of potassium-rich foods our adrenal glands secrete more glucocorticoids to keep our potassium levels in check, which may have the side effect of decreasing the level of inflammation in the body. See my 3-min video Potassium and Autoimmune Disease for the effect this may have on autoimmune diseases such as psoriasis.

Where is potassium found? See my post last week, 98% of American Diets Potassium Deficient. Hint: bananas don’t even make the top 50 sources!

What about autoimmune arthritis? See my previous post Plant-Based Diets for Rheumatoid Arthritis and my videos Preventing Arthritis and Diet & Rheumatoid Arthritis. Eating healthier doesn’t improve everyone’s joint pain, but as with all nontoxic treatment modalities, they should always be tried first.

Plant-based diets may help with other pain syndromes:

as well as other hypersensitivity diseases:

    I am confused. The title says “Plant-Based Diets for Psoriasis”. So, what is the diet for Psoriasis? It does not seem to get a mention above.

      Lawrence: I agree that this post is not terribly clear. Here is my understanding of the first paragraph combined with looking at the links, distilled and in reverse:
      >> psoriasis = autoimmune disease
      >> autoimmune disease = made worse by a lot of inflammation
      >> inflammation = controlled by foods high in potassium (with additional details on the mechanism of how that happens given above and in the links)
      >> potassium = found in plants
      Hence, an explanation for why plant based diets (ie, diets consisting mostly of whole plant foods with no or minimal animal foods) have been shown to help people with psoriasis (see the video linked to above). Sound about right to you?

    I found your video on Auto immune disease fascinating, as a life long sufferer of Psoriasis. My question though is, how do I take in enough potassium? My problem is that I am now taking Sintrom (similar to Warfarin) so have to watch Vitamin K carefully. Can you suggest foods that are high in Potassium, but low in Vitamin K?
    Thank you

    Hi, I’ve read in several books (ie: John Paggano’s Healing Psoriais) that night shades (peppers, potatoes, aubergine, tomatoes and tobacco plants), due to their pro inflmatory effect containing compounds (solanine…), are not recommended for psoriasis sufferers. Is there any scientific truth in this? It would be nice to have a video or an article on this. If anyone has an answer for this, I’d very much appreciate it.
