Individuals with psoriasis are always looking for ways to improve the inflammatory skin disorder, especially natural ways. A recent small study found that following a Mediterranean diet is a simple and effective way to reduce the symptoms of psoriasis (red, scaly patches and persistent itching).

Subjects with mild to moderate psoriasis were randomly assigned to one of 2 dietary groups. The group following a Mediterranean diet for 16 weeks had significantly reduced psoriasis severity and symptoms, when compared to the control group that were just told to follow a low-fat diet. Almost half of the Mediterranean group had a 75% reduction of psoriasis severity and symptoms! None of the low-fat diet group had a reduction in psoriasis severity and symptoms.

Additionally, all persons in the study were using their usual topical therapy for their psoriasis. The improvements in the Mediterranean diet group occurred without significant weight loss.

The Mediterranean diet is rich in fruits, vegetables, whole grains, seeds, nuts, legumes, fish, and olive oil. In the study's Mediterranean diet group, the participants were not only given nutritional advice, but also a weekly provision of extra virgin olive oil. This diet is anti-inflammatory, which is why it may be so beneficial to those with psoriasis.

Over 60 million people worldwide are affected by psoriasis, a chronic inflammatory skin disorder that causes red, scaly patches and persistent itching. A new study has found that following a Mediterranean diet—rich in plant-based foods, extra-virgin olive oil, and a moderate amount of fish, and poultry—could provide relief to psoriasis symptoms.

Well, the results of new research about skin with psoriasis compared to healthy skin isn't surprising. The research found that skin with psoriasis has a distinct microbiome (community of bacteria, viruses, fungi) - one that is different from that of healthy persons.

A main finding was that the types of bacteria were lower (less diversity) on the psoriatic skin. Greater diversity of bacteria is considered good - a sign of health. Levels of Staphylococcus were higher in the psoriatic skin, but healthy skin had higher levels of Cutibacterium and Kocuria.

Oher research also supports the view that microbes are somehow involved with the development of psoriasis. The hope is that someday treatment could be just taking a probiotic pill or applying certain microbes to the skin, perhaps in a lotion. Wouldn't that be great?

Excerpts from Medscape: Psoriasis and Psoriatic Arthritis Show Distinctive Skin Microbiomes

The bacterial diversity in lesional and nonlesional skin of patients with psoriasis (PsO) with or without psoriatic arthritis (PsA) was significantly lower than that of healthy control skin, based on data from 74 individuals. ...continue reading "Psoriasis Has A Microbiome"

It will be great if more studies support a recent study finding that eating a Mediterranean style diet is associated with fewer psoriasis symptoms. The large study, which was conducted in France, found an inverse association with the Mediterranean diet - the more closely a person ate a Mediterranean diet, the less severe their psoriasis symptoms and the lower their serum C-reactive protein levels (which measures chronic systemic inflammation). Key things to remember are that psoriasis is an inflammatory condition and the Mediterranean diet is anti-inflammatory, and the typical Western diet is inflammatory (low in fiber, lots of highly processed foods, few fruits and vegetables, high in sugar, and red meat) .

The Mediterranean diet is rich in fruits and vegetables, whole grains, nuts, seeds, extra virgin olive oil, legumes (beans), fish, and light on red meat. Research finds that micronutrients, fiber, antioxidants, and polyphenols that are present in the Mediterranean diet reduce chronic systemic inflammation.  The Mediterranean diet has other health benefits - for example, it's good for the heart, is good for gut microbes, and linked to lower rates of several cancers. From Medical Xpress:

Could psoriasis patients eat their way to fewer symptoms?

A study of more than 3,500 French psoriasis patients found that the healthier their diet, the less severe their symptoms. Specifically, the closer an individual adhered to the nutritious "Mediterranean" diet, the less onerous their psoriasis became. This was true regardless of whether or not the patient was obese, the French researchers noted.

Published on 10 Comments on Would Probiotics Help In the Treatment of Psoriasis?

Could probiotics have a role to play in the treatment of psoriasis? A recent analysis and review of studies suggests that they might. Psoriasis is a non-contagious, chronic disease affecting about 2 to 4% of the population, and which is characterized by patches of abnormal skin. These skin patches are typically red, itchy, and scaly, and can cover small areas to covering the entire body. There is no cure for psoriasis, but various treatments can help control the symptoms, such as steroid creams, vitamin D3 cream, ultraviolet light, and immune system suppressing medications. 

What did the researchers find? They said that "new evidence suggests that the microbiome may play a pathogenic role in psoriatic disease" - meaning the community of microbes (microbiome) may be involved in this disease. There is dysbiosis of the skin microbiome (microbial community is out of whack) in areas of skin lesions or patches. Areas of skin lesions had a different microbiome ("lesional psoriatic microbiome") compared to healthy skin - and in these skin lesions or patches some microbial species increase which leads to a decrease or elimination of others. Not just differences in bacteria, but also in fungi and viruses.

in psoriasis the microbial community of the gut is also out of whack (dysbiosis of the gut microbiome). And the gut microbiome is different in those with psoriasis limited to just skin patches, and those with complications of psoriasis (e.g., psoriatic arthritis) - and several studies found that these shifts in the gut microbiome occurred before the psoriatic complications became evident. That suggests that probiotics might help. But which ones?

The researchers state: "Other changes observed in gut microbiome studies include a decrease in Actinobacteria. This may suggest a protective role of Actinobacteria, a phylum which includes Bifidobacterium species that have been shown to reduce intestinal inflammation, suppress autoimmunity, and induce Tregs." They go on to state that one 2013 study by Groeger et al demonstrated that eating Bifidobacteria infantis 35,624 for 6–8 weeks in a randomized, double-blind, placebo-controlled clinical trial reduced inflammatory markers (plasma CRP and TNF-a) in psoriasis patients. Bifidobacterium species, including B. infantis, are commonly found in many multi-strain supplements. So I wonder, what happens if people with psoriasis take them over an extended period? Will the skin psoriasis skin patches improve? This is currently unknown. But...If you've had success with probiotics as a  psoriasis treatment - please let me know. What microbes? And for what symptoms of psoriasis?

From Current Dermatology Reports : The Role of the Skin and Gut Microbiome in Psoriatic Disease

Our review of studies pertaining to the cutaneous microbiome showed a trend towards an increased relative abundance of Streptococcus and a decreased level of Propionibacterium in psoriasis patients compared to controls. In the gut microbiome, the ratio of Firmicutes and Bacteroidetes was perturbed in psoriatic individuals compared to healthy controls. Actinobacteria was also relatively underrepresented in psoriasis patients relative to healthy individuals.

Summary: Although the field of the psoriatic microbiome is relatively new, these first studies reveal interesting differences in microbiome composition that may be associated with the development of psoriatic comorbidities and serve as novel therapeutic targets.
