Seborrheic Dermatitis: Do Dietary Preferences Play a Role?

Do Dietary Preferences Play a Role?

Seborrheic dermatitis is a red scaly condition that affects multiple sites including the scalp. It is thought to be closely related to dandruff. Multiple factors contribute including Malassezia yeast. Other factors such as stress, ultraviolet radiation and several others factors too also play a role.

A recent study of 4,379 participants sought to examine the relationship between dietary factors and the development of seborrheic dermatitis. 636 of the participants (14.5%) had seborrheic dermatitis. Data analysis identified specific dietary patterns such as a 'Vegetable', 'Western', 'Fat-rich' and 'Fruit' dietary pattern.

Interestingly, a fruit-rich diet was associated with a 25 % reduction in the risk for seborrheic dermatitis. A Western type diet (high in red meat and processed food) was associated with a 47 % increased risk of seborrheic dermatitis but this dietary pattern seemed to have a link only for women.

The conclusion to the interesting study was that dietary choices likely do impact the development

of seborrheic dermatitis. A fruit-rich diet in particular may reduce the risk.
