- Omega-3 fatty acids may help reduce dryness of your skin.
- Vitamin C is necessary for collagen production, which is a major component of the connective tissue layers of your skin.
- Vitamin A keeps your skin strong so it can function as a barrier to keep bacteria and other pathogens out of your body.
- Selenium is a trace mineral (you only need small amounts of it) that may help prevent skin cancer (learn more about my favorite foods that may prevent cancer).
- Zinc is another trace mineral. It's necessary for wound healing.
- Strawberries, blueberries and raspberries are rich in vitamin C and antioxidants that can fight damage due to free radical exposure.
- Red, orange, yellow and dark green fruits and vegetables all contain pigments like lycopene and lutein. These pigments are natural antioxidants. Fruits and vegetables are also generally low in calories and high in fiber.
- Oysters are rich zinc (and many other minerals) while remaining low in fat.
- Salmon, tuna, sardines, and trout are excellent source of omega-3 fatty acids that keep your skin moist. They're also good sources of lean protein.
- Brazil nuts contain more selenium per serving than any other food. They also contain monounsaturated fatty acids. Serving size is important - they're high in calories, so you only need a few every day.
- Green Tea (both regular and decaffeinated forms of green tea) contains polyphenols that work as antioxidants that may help protect your skin from sun damage.
You should be able to get the nutrients your skin needs from the foods you eat, but if you want to ensure a sufficient intake of vitamins and minerals, you can take a multivitamin supplement. These supplements are generally safe, but it's still a good idea to speak with your health care provider before taking any dietary supplements in large doses.
