Raspberries

A cup of raspberries delivers a whopping 8 grams of fiber (thats more than double whats in a cup of strawberries and about the same amount in a cup of some types of beans). Whats so great about all that fiber? Recent research in the Journal of Nutrition suggests eating more fiber as a way to prevent weight gain or even encourage weight loss. Over the course of the two year study the researchers found that boosting fiber by 8 grams for every 1 000 calories resulted in about 4 ? pounds of weight lost.
