Sugar contributes to inflammation in the body, including seborrheic dermatitis, which is a type of inflammation of the skin, explains the University of Maryland Medical Center. Eating fewer saturated fats from meat and dairy, as well as reducing intake of refined foods and sugar, can help treat dermatitis.
Stress can bring on seborrheic dermatitis, as can oily skin or hair, notes the University of Maryland Medical Center. Dermatitis manifests with symptoms such as burning, stinging, itching and pain, as well as with swelling and redness. In addition, patients with dermatitis may experience thick or scaly skin, blisters, and sores from scratching.
To treat seborrheic dermatitis, a doctor may recommend medicated shampoo, reports the University of Maryland Medical Center. Patients may also try avoiding exposure to environmental and food allergens. Eating more fresh vegetables, whole grains and essential fatty acids found in nuts, seeds and cold-water fish is also a way to treat dermatitis. A patient with dermatitis may benefit from consuming other supplements, such as evening primrose oil, bromelain, borage oil, vitamin C, probiotics and fish oil. Because flavonoids have anti-inflammatory properties, consuming these antioxidants through dark berries and certain plants may be helpful in the treatment of dermatitis.
Herbs are also useful in treating symptoms of dermatitis, states the University of Maryland Medical Center. Patients can use herbs such as licorice, chickweed, marigold and chamomile in a topical cream or salve to relieve the symptoms. Other herbs, such as marshmallow, St. John's wort, Sarsaparilla, and the liquid form of witch hazel, are helpful in treating symptoms as well.
