There is no magic bullet to stop aging, but at some point, most of us wish we could turn back the hands of time.  While there isn't a time machine out there to take us back to our youth, a varied diet which is low in saturated fat, and high in nutrient packed veggies, whole grains and healthy fats can help fight aging.  There are a few foods in particular, that are looked upon as anti-aging superfoods.

1. Avocado - While avocados once received a bad rap for their fat content, these fruits are rich in monounsaturated fats which might improve heart health.  They are also rich in folate and beta-sitosterol, two nutrients that are also associated with lower cholesterol and better cardiac health. In fact, a study from Mexico found that 45 volunteers who ate avocados every day for a week experienced an average 17% drop in total blood cholesterol.

2. Berries - Cranberries, blueberries, blackberries and other berries contain vitamin C and flavanoids, which are powerful antioxidants that may help to prevent some forms of cancer.

3. Dark leafy greens - Spinach and other dark leafy greens contain lutein and zeaxanthin, plant compounds that help protect the eyes.   Greens are also rich in vitamin K, a vitamin that may improve bone density and reduce bone fractures.

4. Yogurt - The live and active cultures found in many yogurts are probiotics which help maintain the function of the GI tract, helping us get the most benefit from the other foods we eat.  Yogurt is rich in calcium for strong bones, and protein to maintain muscle mass.  Japanese studies have also associated the active cultures in yogurt with improved dental health.

5. Beans - Beans like pintos and chickpeas are rich in antioxidants which help prevent cancer.  They are also high in protein and low in calories and fat, helping to maintain muscle mass without upping cholesterol like red meat can.

6. Whole grains - Whole grain foods use the entire grain without stripping away the bran or germ, which contain fiber, B vitamins and healthy fats.  Choosing a diet rich in whole grains like whole wheat, oats, barley and rye, may improve heart health, help you manage your weight and reduce the risk of certain cancers and diabetes.

7. Fatty fish - Fatty fish like salmon, tuna, mackerel, sardines and trout are full of omega-3 fatty acids.  Omega-3s are beneficial for both brain and heart health.  They can reduce cholesterol and stroke risk, and are also associated with a lower risk of developing Alzheimer disease.

8. Nuts - Nuts like walnuts and almonds are also rich in "good" fats.  They contain unsaturated fats, omega-3s, fiber and L-arginine, all substances which are known to improve cardiac health. Since they don't need to be cooked, nuts make a quick and easy heart healthy snack.

9. Wine - Red wine, which is packed with antioxidants like resveratrol, may help prevent heart disease, diabetes and memory loss when consumed in moderation.  A recent study from Spain has shown that women who consumed alcohol had a lower risk of Alzheimers disease than people who had never had a drink.

10. Water - Adequate fluid intake is important to help your body remain hydrated and an excellent anti-aging tool. Proper hydration makes the skin smoother, improves digestion, helps control body weight and improves joint pain.  Hydration is also important to help the brain function properly so you can think clearly.
