The results “showed that dietary habits were not associated with an increased risk of seborrheic dermatitis. Healthy dietary choices are important for overall health. Anti-inflammatory or Mediterranean-style dietary approaches have been found to improve many aspects of health, especially in the context of inflammatory diseases. Seborrheic dermatitis is an inflammatory condition and may improve when dietary choices include foods that inhibit rather than promote inflammation.
More information about these dietary approaches can be found in the comprehensive health tool Choosing a Diet. One such study, published in the Journal of Investigative Dermatology (201), found that a “Western dietary pattern consisting mainly of meat and processed foods that have been cooked, canned, frozen, dried, baked and packaged could trigger seborrheic dermatitis. Eating fruits, especially citrus fruits such as oranges and bell peppers, can help you fight inflammation in seborrheic dermatitis. Medical organizations, including the National Eczema Association (NEA), the American Academy of Dermatology (AAD), and the Mayo Clinic, do not consider dietary factors as a cause of this condition.
Seborrheic dermatitis usually occurs on the body in places where there are oil-producing glands, such as the upper back, nose, and scalp. Researchers looked at lifestyle factors, primarily diet, to see if there are any nutritional recommendations for seborrheic dermatitis. There are things you can do to feel better, but because there are no specific nutritional guidelines for seborrheic dermatitis, changing your diet may not be one of them. Seborrheic dermatitis is an inflammatory skin disease characterized by scaly, red or yellowish scales that resemble dandruff.
Seborrheic dermatitis in infants is commonly referred to as “cradle cap” because it most often appears on the scalp. A study of 60 patients with seborrheic dermatitis examined a topical gel containing 4% quassia extract and compared it to treatment with 2% ketoconazole and 1% cyclopyrox olemine for four weeks. Because it promotes the growth of yeast that contributes to seborrheic dermatitis and can cause a rebound outbreak when stopped, hydrocortisone should only be used to minimize symptoms along with topical medications and should never be used alone for treatment. Some aloe vera compounds have been found to have anti-inflammatory and anti-itching properties that may be beneficial in seborrheic dermatitis.
It’s not clear why some people get seborrheic dermatitis and others don’t, but the reason probably has to do with differences in immune responses to Malassezia. However, some scientists believe that genes and hormones may play a role in the origin of seborrheic dermatitis. Common triggers for seborrheic dermatitis include stress, hormonal changes or illnesses, harsh detergents, solvents, chemicals and soaps, cold and dry weather, medications such as psoralen, interferon, and lithium. But this skin condition is not diet-related, according to the British Association of Dermatologists (BAD), and current research does not point to any specific foods that could trigger it.
Unfortunately, there is no recommended diet for seborrheic dermatitis for people with this disorder that could cause a red, sometimes itchy rash on the scalp, face, or chest.
