Did you know that specific nutrients can function as a biological sunscreen? Learn which foods contain photoprotective compounds—regular consumption of these may help shield skin cells from ultraviolet-induced damage. Discover how a well-balanced diet can serve as a complementary strategy alongside conventional sun protection methods.
Is it the diet that should be included in the menu at all?
Some of the most effective nutrients are beta-carotene, lycopene, lutein and zeaxanthin. Flavonoids maintain an adequate level of moisture in the skin. Carotenoid not only protects the skin from sunburn but also naturally improves its color. There are over 600 different carotenoids. These are the most efficient ones: beta carotenes, lycopenes, luteins, and zeoxanthines.
Photoprevention
In addition to redness, blistering, and tanning of the skin, excess exposure to sunlight can lead to long-term damage, as well as premature skin aging (caused by UVA rays) and skin cell mutations (caught by UVB radiation), resulting in cancer. Studies show that some nutrients reduce photosynthesis damage, help to strengthen the skin's resistance to ultraviolet radiation internally, and so nutrition can play an important role in the prevention of skin cancer.
The CD-SPF factor in food
The Sun Protection Factor (SPF) is a sun protection factor that determines the degree of protection provided by sunscreen filters. This value tells us how long you can stay in the sun without getting burned. Clinicians specializing in photo-dermatology have assigned its value to foods rich in natural antioxidants. Thus, the CD-SPF (Continual Dietary-Sun Protection factor) is the factor that defines the strength of the protective effect of food products.
