Enjoy the spice of life with healthy herbs. According to a new study from the University of Nebraska, herbs not only improve the taste of your food, but can also help fight the free radicals that age you. Excellent choices include basil, cayenne, oregano, rosemary, sage and ginger. All contain high percentages of polyphenols, substances which help reduce cell damage that increases your risk of cancer and heart disease. Both fresh and dried herbs offer the benefits of polyphenols. Always store dried herbs in sealed jars in a cool, dark place to maintain the nutritional content. Exposure to heat, light and air all reduce their antioxidant power as well as their flavour.
