Preserved fruit that has been sealed in a can or airtight jar often has a higher amount of sugar and thus more calories as compared to fresh fruit. However, it is possible for canned fruit to have the same calories and nutritional information as its newly harvested counterpart. When picked and preserved during the peak period, canned fruit may even retain a higher percentage of nutrients. All fruits are mostly made of carbohydrates, although calories in canned fruit can also come from fats and small amounts of protein. Fruits are all said to have good nutritional value since they contain a lot of vitamins and minerals per serving, including potassium, phosphorous, and vitamins A and C. Most varieties of fruits that are canned have a naturally high amount of sugar. For example, peaches, pears, and papaya each contain over 40 grams of sugar per 100 grams. If excess sugar has been added during the fruit canning process, that is typically evident by a high number of calories as indicated in the nutrition facts. The calorie chart below can be used as a guideline, but exact amounts for each brand will differ depending on the amount of syrup used, if any.
