The medical community often fears placing blame on certain foods as disease triggers. However, numerous studies have indicated a correlation between weight gain (and obesity) and developing psoriasis.
For instance, Dr. Jerry Bagel, a New Jersey-based board-certified dermatologist and recognized expert in the treatment of psoriasis explains that, “Specific molecules secreted from fat cells [can] make psoriasis even worse,” which is why weight management and the avoidance of empty, high-caloric beverages (i.e., soda and mixed cocktails) is vital to any psoriasis patient’s eating regimen.
5. White Bread
While a gluten-free diet to alleviate psoriasis sufferers is considered controversial by many health care professionals, the National Psoriasis Foundation points to research that finds 25-percent of psoriasis patients also suffer from gluten sensitivity. The exact link is the HLA CW6 gene, which is linked to psoriasis as well as increased gluten (or gliadin protein) sensitivity, pinpointed in a 2010 study published by the National Institutes of Health.
Further research conducted by the Brazilian Annals of Dermatology notes that patients with gluten sensitivity showed significant improvement in psoriasis symptoms when adhering to a gluten-free diet.
6. Sugary Treats
A high-sugar diet may not go hand in hand with psoriasis, but it goes hand in hand with weight gain, according to the National Psoriasis Foundation. In fact, researchers have established a link between obesity and increased risk for psoriasis, psoriatic arthritis, and worsened psoriasis severity (if you already have the condition).
Dr. Wilson Liao, the co-authored of a analysis of diet on psoriasis that was published by the Journal of the American Academy of Dermatology, explains that that, being obese may trigger psoriasis in those already predisposed to the disorder. Dr. Liao explains this may be due to the secretion of cytokines by fat cells, which trigger inflammation.
