Do carbs make psoriasis worse?
Carbohydrates do not cause psoriasis, but for some people diets high in refined carbs and sugar may contribute to inflammation and weight gain, which are linked with worse symptoms. Whole-food, lower-sugar eating may help, though responses are individual and medical care remains essential.
Carbohydrates, Inflammation and Psoriasis
It is important to be precise: psoriasis is driven by immune and genetic factors, not by carbohydrates. Diet is a possible modifier for some people rather than a cause.
The plausible link
Diets high in refined carbohydrate and added sugar are associated with higher body weight and markers of inflammation in general health research, and excess weight is linked with psoriasis severity in some studies. Through that indirect route, heavily processed high-sugar diets could worsen things for certain individuals.
Not all carbs are equal
Refined carbs and sugary drinks are the usual concern, not vegetables, legumes or whole foods that also contain carbohydrate. A blanket fear of all carbs is not supported. If you want to reduce refined carbs and sugar, you can estimate a lower-carb intake to plan around whole foods.
Practical view
Reducing ultra-processed, high-sugar foods is reasonable for general health and may help some people, but it will not cure psoriasis. For related questions, you can read the keto FAQ.
