Bright Blossom Inc. (Location: Suginami-ku, Tokyo; CEO: Shinichi Goto) conducted a survey targeting dermatologists regarding the "impact of gluten intake on rough skin and the intestinal environment."
While there are various causes of rough skin, in recent years, there has been growing interest in the relationship between wheat (gluten), the intestinal environment, and skin troubles, making the review of dietary habits increasingly important. There are cases where skincare alone does not lead to sufficient improvement.
Although it is known that in certain diseases (Celiac disease and Non-Celiac Gluten Sensitivity), wheat (gluten) affects the intestines and overall physical condition, it is not definitively clear whether the same effects occur in healthy individuals. However, it is sometimes said that "wheat (gluten) puts a burden on the intestines" and "it can be related to rough skin."
How are these ideas perceived in actual clinical practice?
Therefore, Bright Blossom Inc. (https://br-blossom.com/) conducted a survey among dermatologists regarding the "impact of gluten intake on rough skin and the intestinal environment."

The majority of dermatologists prioritize intestinal conditions when treating skin troubles!
First, when asked, "What are the most common causes of skin troubles seen in clinical practice?", the most common answer was "Poor dietary habits (58.3%)," followed by "Poor intestinal environment (52.8%)" and "Stress (45.4%)."
As causes of skin problems, internal physical conditions such as "dietary habits" and "intestinal environment" were cited more frequently than external factors like "inadequate skincare," "UV rays, dryness, friction, etc."
This result supports the notion that the skin is a mirror reflecting one's state of health.
So, to what extent is the condition of the "intestines" being considered among these factors?
Next, when asked, "To what extent do you value the condition of the intestinal environment when treating skin troubles?", about 90% responded either "Very much value it (44.6%)" or "Value it to some extent (45.2%)."
It appears that grasping the intestinal environment is an important matter in the medical treatment of skin troubles.
It can be seen that dermatologists recognize that intestinal conditions influence skin problems.
Then, what kind of advice are they giving to patients during actual consultations?
When asked, "Besides skincare, what kind of guidance do you often provide during consultations for skin troubles?", the most common response was "Guidance regarding the intake of specific food ingredients (lactic acid bacteria, fermented foods, etc.) (54.6%)," followed by "Guidance on improving sleep and lifestyle habits (48.5%)" and "Advice on dietary habits (45.8%)."
It became clear that about half of dermatologists are providing guidance on the intake of specific food components.
Also, because many provide guidance on "sleep/lifestyle habits" and "dietary habits," it seems that a fundamental review of diet is considered important, rather than just symptomatic treatments like prescribing oral medications or applying topical ointments.
What do patients misunderstand about the causes of skin troubles?
Following this, when asked about "factors that you feel patients often misunderstand regarding the causes of their skin troubles," the most common answer was "Not knowing the relationship with the intestinal environment (52.1%)," followed by "Tending to underestimate the impact of dietary habits (46.2%)" and "Tending to think that only skincare is the cause (43.1%)."
It was shown that many patients have a tendency to perceive that "skin problems only happen on the surface of the skin."
The fact that factors such as the intestinal environment and dietary habits are often overlooked may be one reason why treatment and improvement are delayed.
