Clinical Report: Kiwifruit's Effect on Skin Examined
Overview
Daily consumption of two SunGold kiwifruit for 8 weeks significantly increased skin vitamin C levels and improved skin density and epidermal cell proliferation in individuals with low baseline plasma ascorbate. This pilot study establishes a direct relationship between dietary vitamin C intake and skin health.
Background
Vitamin C is essential for skin health, influencing collagen synthesis and cellular functions. Understanding how dietary sources of vitamin C, like kiwifruit, affect skin ascorbate levels and function is crucial for developing nutritional strategies for skin health. This study provides valuable insights into the impact of dietary vitamin C on skin structure and renewal.

Key Findings
Daily intake of two SunGold kiwifruit increased skin ascorbate levels by 51%.
Skin density improved from approximately 0.15 to 0.23 scanner units after 8 weeks.
Epidermal cell proliferation increased from 21 to 27 intensity units.
Epidermal ascorbate levels were found to be higher than dermal levels, with a ratio of 2.0.
Ascorbate levels in skin compartments correlated positively with plasma levels, indicating active uptake.
Clinical Implications
Healthcare professionals should consider dietary interventions, such as increasing fruit intake, to enhance skin health through improved vitamin C levels. This study supports the notion that dietary sources can effectively influence skin function and structure, particularly in individuals with low baseline vitamin C status.
Conclusion
The findings underscore the importance of dietary vitamin C in promoting skin health and suggest that increasing intake through foods like kiwifruit can yield significant benefits for skin function.
