For people on a diet, fruits are an important part of the diet. Grapes contain very low calories and are loaded with fibre, which is essential in preventing hunger pangs as it keeps you full for long.
However, raisins carry more calories than grapes. In the process of drying grapes out, there is a concentration of antioxidants and sugar which takes the form of calories. A half-cup of raisins contains approximately 250 calories, while the same serving of grapes contains only 30 calories.
