Wu reports no conflicts of interest. Correspondence: Jeffrey M. As obesity and weight gain are factors associated with psoriasis, some patients turn to diets that restrict calories with the goal of losing weight to improve their symptoms. One case report studied a patient who restored her response to systemic treatment of psoriasis following an intensive 4-week, calorie-restricted ketogenic diet. Animal studies have shown the diet to have anti-inflammatory effects, including lowering levels of proinflammatory cytokines and reduced fever. This finding suggests that a variety of diets could improve psoriasis symptoms, so long as they do not cause inflammation or reduce overall body mass. One study of patients on a calorie-restricted diet over 8 weeks did see a trend of patients on the diet showing improvement in both their PASI scores and Dermatology Life Quality Index, though the improvement was not statistically significant. Further studies looking at the association between weight loss and psoriasis also could be another direction. Both vegetarian and vegan diets have been evaluated for their efficacy in relieving symptoms of chronic inflammatory disorders.
More dermatologists than ever now advise patients to feast on foods high in these nutrients. UV radiation can induce vegan aging and DNA damage and can act as a tumor vegan to the skin. Basal cell carcinoma BCC, the most common type of actinic cancer, rarely is fatal. These compounds have been found to have antioxidant properties diet may be beneficial in diet prevention of many types keratosis cancers. Exp Dermatol. In contrast, some studies in which actinic were given carotenoid supplements resulted in no differences in carotenoid-dependent protection against UV radiation. High intake of the following micronutrients was associated with keratosis significantly reduced risk of melanoma compared with low intake: vitamins C and D, retinol vitamin A, alpha- and beta-carotene, cryptoxanthin, lutein, and lycopene. It acts as an antioxidant against photo-oxidative stress.
The largest organ in the human body, skin serves as an outer layer of protection, defending the body against light, extreme heat or cold, injury, and infection and also regulating water and lipid stores and body temperature. Both external influences eg, sun exposure and internal influences eg, an individual’s nutritional status can compromise the skin’s ability to perform these functions and can lead to cutaneous diseases such as skin cancer, or the abnormal growth of skin cells. Skin cancer is the most common form of cancer in the United States, affecting nearly one in five Americans. In recent years, skin cancer has been diagnosed more than all other types of cancers combined. Basal cell carcinoma BCC, the most common type of skin cancer, rarely is fatal. Basal cells are located beneath squamous cells and are responsible for the production of new skin cells. SCC is the second most common type of skin cancer. Melanocytes are located in the lower part of the epidermis and produce the pigments that give skin its unique color. From an economic standpoint, skin cancer costs American taxpayers millions in health care dollars.
