Psoriasis

Psoriasis is a chronic, immune-mediated disease that results from the overproduction of skin cells, resulting in their accumulation on the surface of the skin, which causes red, scaly plaques that may itch and bleed. It is estimated that approximately 7.5 million Americans and nearly 3 percent of the world's population are living with psoriasis and nearly one-quarter of those people have cases that are considered moderate to severe.

Low-calorie diets linked to higher psoriatic arthritis risk, genetic study suggests

This Mendelian randomization study found that low-calorie diets may slightly increase the risk of psoriatic arthritis, while vegetarian and gluten-free diets showed no causal links to psoriasis, acne, or atopic dermatitis. The findings challenge assumptions about universally beneficial dietary patterns and highlight the need for cautious interpretation of dietary interventions in inflammatory skin disease.
