2. Raisins

While most fruits (besides avocado), are fat-free and chockfull of vitamins and minerals, raisins are simply too dense in carbohydrates to be considered a diet food.

At 115 grams of carbs per one cup (145 grams) serving, you would probably be better sticking to lower carbohydrate and thus lower calorie fruits, like strawberries, apples, oranges or peaches.
