A high fruit intake was associated with less seborrheic dermatitis, whereas high adherence to a “Western” dietary pattern in females was associated with more seborrheic dermatitis, reports a new study published in the Journal of Investigative Dermatology.
Seborrheic dermatitis appears on the body where there are a lot of oil-producing (sebaceous) glands like the upper back, nose and scalp. Its exact cause is unknown, although genes and hormones play a role. It most commonly affects adults between the ages of 30-60 and infants under 3 months.
Martijn G.H. Sanders and associates conducted to determine whether specific dietary patterns or total antioxidant capacity are associated with seborrheic dermatitis.
Participants in the Rotterdam Study with a skin examination and a food-frequency questionnaire were included. Total antioxidant capacity was assessed on the basis of the ferric reducing antioxidant potential of each food item. In total, 4,379 participants were included, of whom 636 (14.5%) had seborrheic dermatitis. In total, 4,379 participants were included, of whom 636 (14.5%) had seborrheic dermatitis.
The study found that the “fruit” dietary pattern was associated with a 25% lower risk, while the “Western” dietary pattern was associated with a 47% increased risk in females. Other factors, such as the total antioxidant capacity, were not associated with it.
The authors suggested that the current treatments for the disease only provide a temporary relief, identifying modifiable lifestyle factors may reduce the disease burden.
Seborrheic dermatitis is a common skin condition that mainly affects the scalp. It causes scaly patches, red skin and stubborn dandruff. It can also affect oily areas of the body, such as the face, sides of the nose, eyebrows, ears, eyelids, and chest.
