I’m going to keep a food diary to keep track of my psoriasis. I’d like to know how I can tell which foods will trigger my psoriasis – is there a delay between eating something and the onset? Will I know immediately if a certain food has set off psoriasis?
The link between psoriasis and diet is not strong. I do advise people with psoriasis to refrain from too much alcohol and smoking as these may aggravate psoriasis.
As for diets, psoriasis is not linked conclusively to any foods and there are no usual recommended diets for psoriasis. Keeping a food diary may be more relevant for eczema, which may be food related or triggered in some cases.
I do encourage eating healthily as individuals with psoriasis have a higher risk of being overweight and developing diabetes and high cholesterol. Psoriasis is not due to food allergies.
There have been some small studies to suggest that fish oils may be helpful and low gluten diet may be beneficial but the evidence is not robust.
