Psoriasis: a balanced diet to reduce inflammation of the skin
An American scientific study suggests that diet has a real role to play in the occurrence of inflammatory skin diseases such as psoriasis. A diet too rich in fats and sugars causes an imbalance of the intestinal microbiota which would result in inflammation of the skin.
Published in the Journal of Investigative Dermatology, the study indicates that in contrast, switching to a more balanced diet restores gut health and suppresses inflammation in the skin.
“Previous studies have shown that the western diet, characterized by its high sugar and fat content, can lead to significant skin inflammation and psoriasis outbreaks ”commented Sam T. Hwang, professor and chair of dermatology at UC Davis Health, and lead author of the study. “There is a clear link between inflammation of the skin and changes in the gut microbiome due to food intake ”, added the researcher, indicating that, in the study, carried out in mice,“The bacterial balance in the gut was disrupted soon after starting a Western diet and worsened inflammation of the psoriatic skin and joints”.
The study was conducted here in mice in which psoriasis was induced by biological manipulations. First fed “Western style” for six weeks, with a diet high in sugar and saturated fat, the mice were then divided into two groups: a group that continued the Western diet for another four weeks and a group who switched to a balanced diet for the same length of time.
Verdict: A diet high in sugar and fat for 10 weeks predisposed mice to inflammation of the skin and joints. In contrast, mice that were switched to a more balanced diet had less peeling of the skin than mice on a western diet. For the authors, this suggests that a change in diet could partially reverse the pro-inflammatory effects and alteration of the gut microbiota caused by the Western diet.
“It was quite surprising that a simple modification of the diet containing less sugar and fat could have significant effects on psoriasis.”, Commented Zhenrui Shi, co-author of the study, in a communicated. “These results reveal that patients with psoriatic skin and joint conditions should consider switch to a healthier diet”, He estimated.
A disease that weighs on the private lives of patients
A investigation carried out in May and June 2021 by the France Psoriasis association on 1,409 patients reveals the extent of the embarrassment qIt causes this disease on intimate relationships. 41% of patients surveyed say they have a sexual dysfunction linked to their psoriasis, women being more affected than men. 28.1% say they have reduced the frequency of their sexual activity. The causes of these dysfunctions can be as much physical as psychological and the consequences multiple, in particular the loss of self-confidence, frustration or isolation. The survey also shows that 81% of patients have never had a conversation with their doctor about their sexual dysfunction. The association calls on patients and doctors to put an end to this taboo for better care.

Smoking can increase your chances of developing psoriasis, and if you already have it, it can make it worse.

Follow appropriate treatment

Talking about the disease to loved ones
Psoriasis can affect your mental health. According to a survey conducted in 2017 by the association France Psoriasis, 76% of patients thus feel embarrassed by the gaze of others. One in three patients is even ashamed of it. A situation that has serious repercussions on their daily life and in their relationships with others, to such an extent that some prefer to limit their social activities so as not to show their body.
Psychological support, through discussion forums or group therapy, helps to come to terms with this disease. And live like the others also involves the support and the benevolent gaze of those close to them. Putting what worries into words brings relief to the patient and those around him.
“It is enough to explain the disease and to say that it is neither contagious nor dirty, and that one treats oneself, explains Dr. Consoli, psychoanalyst dermatologist. It is common to imagine that others feel disgust. . However, it is essential not to project on others what you feel. ”
Don’t ignore the warning signs of depression, such as general sadness, fatigue, changes in appetite or sleep patterns, unexplained irritability, and a lack of interest in your usual hobbies. Confide in a friend or relative you trust, and make an appointment with a healthcare professional for advice.
