Seborrheic dermatitis and diet

Seborrheic dermatitis is a common skin condition, characterised by red, scaly patches on various parts of the body.
The exact causes of this disease are numerous, and we already know that lifestyle (such as regular smoking or alcohol consumption) can influence the onset of the condition.

What about diet? This article takes a look at the latest developments in this area.

Adopting healthy eating habits

A balanced diet has been proven to help combat seborrheic dermatitis. In particular, it can prevent symptoms from getting worse ^(1-2). Many patients who changed their diet reported an improvement in their condition ^(1-2). 
But what do we mean by ‘suitable diet’? What’s important to know about seborrheic dermatitis and which foods to avoid? For the moment, our knowledge is based on observations. 

On the other hand, to avoid aggravation of seborrheic dermatitis, foods to avoid include white bread, grilled or fried foods and coffee. In general, a Western diet high in saturated fats and processed foods is often associated with a more severe form of this condition (3-4).

However, before recommending dietary alterations, with foods to be avoided, as a treatment for seborrheic dermatitis, further research is needed to confirm these observations. Experts recommend keeping a food diary, noting down everything you eat. This helps to identify any links between foods and symptoms. It’s also advisable to consult a nutritionist for personalised advice. 
In addition, research continues to explore the links between diet, intestinal health and dermatological conditions. Inflammatory skin conditions such as seborrheic dermatitis and potential links to the liver ire also a subject of research.

Whatever the case, a balanced diet remains essential for health in order to provide the necessary vitamins that are essential for the general functioning of the body: 

Conversely, it’s important to limit your consumption of certain foods, such as saturated fats (cream, etc.), quick sugars (sweets, cakes, etc.) and fried, grilled or smoked foods. As far as possible, opt for home-made dishes rather than ready-made meals, which often contain large amounts of salt and/or sugar, as well as all kinds of additives.

Food, sleep, cosmetics...

As well as diet, which can have an influence on skin and seborrheic dermatitis, a healthy lifestyle in general is important and necessary for good skin health: 

• Lack of sleep,
• the use of unsuitable cosmetics,
• and overexposure to UV rays

are all factors that can make the skin more fragile.

Exposure to toxic substances such as tobacco and alcohol, which are not recommended because of their tendency to cause flare-ups, is also prompting researchers to further explore the possible link between seborrheic dermatitis and the liver. If you feel strongly dependent on these substances, talk to your doctor, who will be able to help you.
