Una diet rich in ultra-processed foods could negatively influence the trend of the psoriasis. This is what emerges from a study published on Jama Dermatologywhich analyzed the link between this type of food – rich in sugars, fats and additives – and the typical inflammation of the disease. Psoriasis is a chronic inflammatory skin pathology, on a genetic and immune basis, but with an increasingly recognized environmental component. Among the potentially aggravating factors there is also nutrition.
What are ultra-processed foods
Packaged snacks, carbonated drinks, sugary cereals, ready dishes and other highly transformed industrial products are included in this category. They are often enriched with dyes, emulsifiers and artificial aromas, they have a high content of sugars, saturated fats and salt, but they are poor in essential fiber and micronutrients. Their consumption has increased exponentially in recent decades, especially in western countries. In addition to being associated with obesity, diabetes, cardiovascular diseases and colorectal cancer, they could now also fall among the risk factors for psoriasis.
The French study
The researchers analyzed the data of over 18,500 adults (average age 62 years, mainly women), classified in three groups: without psoriasis, with psoriasis not active and with active psoriasis. 10% of the sample reported having the disease; In 4% of cases it was an active form. All participants have compiled detailed food diaries. The results show that those who consumed more ultra-processed foods had a higher 36% risk of presenting the active form of psoriasis than those who ate less, even after correcting the data by age, BMI, habits and comorbidity.
Association, not cause-effect
The study is observational, therefore it does not demonstrate a direct link. It is possible, for example, that the presence of active psoriasis affects the lifestyle, bringing to less healthy food choices. However, the labor force lies in having considered numerous confusing factors, suggesting that the link between ultra-processed foods and psoriasis could be independent of the effect of obesity only.
A hypothesis to be explored
More solid studies – such as controlled and randomized – will be needed to understand whether to change the diet can really influence the evolution of the disease. Meanwhile, this study offers a first useful starting point to reflect on the role of nutrition in the management of psoriasis, and on the possibility that what we eat can help feed inflammation.
