Canned fruit packed in juice is more healthy than the one packed in sugar syrup.
Explanation:
Fruits like apples, peaches, pineapples etc are peeled, cut and stored in cans which are filled either with sugar syrups or their own fruit juices. Sugar syrups are either made heavy or light depending upon their dilution with water.
The main advantage of taking fruits canned in juice rather than in the sugar syrups is the difference in the overall calorie content. The sugar syrups increase the calorie content from around 85 – 200 calories depending upon its strength.
Fruits like peaches are cut and stored in cans filled with their own juice diluted with water. The can usually contain about half a cup of juice and still will increase calories marginally only, like around 60 calories.
So based on the calorie content, it is healthier to take fruits canned in their juices.
