Guava
Guava is rich in vitamin C, a crucial antioxidant for wrinkle prevention as it promotes collagen formation and skin regeneration. One guava (55g) contains 125.6mg vitamin C which meets the daily requirement for adults; 75mg for women and 90mg for men. Fruits and vegetables are the best sources of vitamin C, including red and green peppers, raw tomatoes, broccoli, grapefruit, kiwi, strawberries and oranges.
It's important to note that the potency of vitamin C can be diminished by cooking and prolonged storage, but steaming may lessen such losses. In general, consuming five varied servings of fruits and vegetables each day can provide an adequate amount of vitamin C to meet your daily needs.
