Dietary factors and antioxidants for skin health and longevity

Nutritional research highlights the role of specific foods and substances in preserving skin structure, elasticity, and combating aging. While ultraviolet rays are primary drivers of skin aging, infrared radiation, pollution, and temperature changes also contribute to collagen loss and wrinkle formation.

Key dietary components include:

- Carotenoids: Found in brightly colored fruits and vegetables like carrots, peppers, and tomatoes, pigments such as lutein, lycopene, and beta-carotene accumulate in skin tissue to provide natural protection against UV rays. They also assist in synthesizing hyaluronic acid and collagen. - Healthy Fats: These serve as a moisturizing barrier and protect against energy-related damage. - Fermented Foods: These support the gut-skin connection.

Additionally, the flavonoid luteolin is gaining attention for its potential longevity benefits. As an antioxidant, it may promote cellular self-cleaning, reduce inflammation, and influence NAD+ levels, which are considered vital for healthy aging processes.
