The Impact of Nutritional Diet on Skin Health and Anti-Aging

In recent years, with the improvement of economic level, people's pursuit of quality of life and healthy lifestyle has been strengthened, and skin care has gradually received attention. The impact of diet on skin condition has become a hot topic of public concern. As the first line of defense of the human body, the skin can effectively resist ultraviolet rays, pathogens and chemicals, but with the increase of age and the occurrence of certain diseases, its barrier function is affected to varying degrees. Adequate nutrient intake and healthy eating habits are essential for skin health, while unhealthy eating habits may have a negative impact on the skin. In addition, skin health is also affected by the "skin-gut axis". Poor eating habits and stress can lead to an imbalance of intestinal flora, which can cause skin diseases. According to the World Health Organization, global healthy life expectancy has increased in the past two decades, and improving the quality of life of the elderly and slowing down the aging process have become important issues for the international community. This article focuses on the impact of a healthy diet on skin health, especially closely related to anti-aging. Studies have shown that nutrients such as plant extracts, vitamins, and antioxidants are beneficial to the skin, and the Mediterranean diet pattern is widely recognized as a healthy diet and has a positive effect on the skin. Although the diversity of dietary interventions is complex, the long-term effects of a nutritious diet on health need to be further studied.
