Fish oils, which are rich in fatty acids, may help to prevent psoriasis and tumour growth.
A member of the Division of Rheumatology at the Medical College of Wisconsin wrote to the Lancet pointing out that several studies have demonstrated a lower incidence of psoriasis in Greenland Eskimos than in European controls.
"This has been attributed to the Eskimo's fishy diet which is high in Omega 3 fatty acids," said the study. Apparently, psoriasis sufferers have a substance causing inflammation which fish oil components can calm.
"Clinical trials have demonstrated an improvement in psoriasis with the addition of fish oil to the patient's regimen, wrote in Geraldine McCarthy.
