The majority of studies and online discussion tend to focus on isolating specific foods which may be creating issues within the body. Once these foods have been isolated, they are removed from the diet, and this can provide long-term relief for the specific individual.
The biggest issue with this approach is that attempting to isolate specific foods as the cause of everyone’s seborrheic dermatitis is virtually impossible due to the variation from one individual to the next. Even medical review literature suggests that common exclusion diets are not very effective method for resolving unselected atopic conditions . If considering this method, the strongest potential seems to lie in a customized approach, which involves a discovery phase where an individual attempts to find potential trigger foods.
The discovery phase of this treatment approach can involve long periods of time, increases risks of nutrient deficiencies, may induce social stress, and can make one very self-conscious, and even then the possibility of false positive results due to incorrectly observed patterns still exist. These issues appear to be the reason why it is not a very popular treatment approach amongst the medical community.
