Answer

Ample literature suggests that weight loss can help psoriasis, but other attempts to show improvement with more specific diets, such as a gluten-free diet, are less conclusive. Studies of very-low-calorie diets and the “Mediterranean Diet" have both shown improvement in anecdotal reports and small studies. [53, 54] Nutritional supplements have shown limited benefit, with the exception of fish oil. [55] Vitamin D itself has also been reported to be of benefit in small studies. [56] Much more work needs to be done before enthusiastic support of any particular supplement or dietary plan may be offered.
