An ex­pert view

Dr Roula Amer, a der­ma­tol­o­gist at the Amer­i­can Hos­pi­tal of Dubai, says, “Al­though there are many re­ports about peo­ple who be­lieve diet af­fects their pso­ri­a­sis, to date there is no study prov­ing a link. This does not mean that there might not be one.

“Some clin­ics rec­om­mend an omega-3 diet for pso­ri­a­sis – mainly fish and veg­e­tar­ian. Oth­ers rec­om­mend lim­it­ing an­i­mal foods such as sausage, cream, but­ter and eggs, as they con­tain arachi­donic acid, and are con­sid­ered ‘acid bombs’ that pro­mote in­flam­ma­tion. Some sug­gest pso­ri­a­sis pa­tients avoid foods that in­crease uric acid and blood lipids (such as of­fal, as­para­gus and fatty foods) and foods with an ef­fect on the ner­vous and vas­cu­lar sys­tem (such as cof­fee, preser­va­tives, dyes, pep­per, pa­prika, curry and chilli).

“Some doc­tors do see the liver’s role as highly im­por­tant. If the nat­u­ral in­testi­nal flora are strongly colonised by yeast, for in­stance, it can lead to a build-up of tox­ins that keep the liver un­nec­es­sar­ily busy. If that hap­pens the im­mune sys­tem will even­tu­ally get ex­hausted and not know any­more what it should de­fend first.

“How­ever, there are no stud­ies show­ing that in­testi­nal coloni­sa­tion with yeast can lead to a wors­en­ing of pso­ri­a­sis or that re­or­gan­i­sa­tion of the in­tes­tine (through foods or sup­ple­ments) im­proves pso­ri­a­sis. That does not mean such a cor­re­la­tion can be ruled out.

“In gen­eral it’s rec­om­mended that pso­ri­a­sis pa­tients should main­tain a healthy weight and fol­low a healthy bal­anced diet – es­pe­cially if in ad­di­tion to pso­ri­a­sis the pa­tient also suf­fers from other con­di­tions such as obe­sity, di­a­betes, gout, liver disease, bil­iary dis­or­ders or di­ges­tive dis­or­ders. Pa­tients should also mon­i­tor their pso­ri­a­sis and if their skin wors­ens af­ter eat­ing cer­tain foods they can try to stop eat­ing them and ob­serve what hap­pens. Ex­treme di­ets should be avoided though as they are some­times time­con­sum­ing, dif­fi­cult to stick to and, in some cases, even harm­ful.”
