Does your approach to nutrition focus on the negative: eat less fat , avoid salt, reduce calories, watch out for pesticides, lower cholesterol, and absolutely no dessert? Well, it may be time to make some adjustments to your diet of deprivation. Change that attitude and take a positive approach to eating healthy.

There are actually many foods with a big "yes" written all over them -- foods you should eat more of, more often. The following eight foods may already be part of your diet. If they are, it never hurts to eat them more often. If they aren't, make an attempt to start including them. Their health benefits are coming to light in scientific and epidemiological studies, proving that these eight foods are powerhouses of good nutrition and disease prevention.

Tea: In this category, we are referring specifically to non-herbal, green teas and, to a lesser extent, black teas. These teas contain an antioxidant compound known as polyphenol. While studies are still incomplete, they do show that the polyphenols may help prevent cancer from forming, stabilize or shrink present cancers, and prevent cancers from spreading. Why? It appears that the polyphenol prevents the oxidation that causes damage to DNA, turning normal cells into cancer cells.

There is also evidence suggesting that tea may protect against heart disease. Tea polyphenols may reduce blood cholesterol and reduce blood pressure and also prevent the formation of clots that can lead to heart attack or stroke. Both regular and decaffeinated tea, as well as iced tea have significant levels of polyphenols -- so pick your favorite brew, and begin to enjoy your daily tea time.
