Canned food can be a great way to save money or time on items that are more expensive to buy or labor-intensive to prepare when fresh. The nutritional value of canned foods is often similar to fresh or frozen foods, but there are some things to watch out for.
Canned is a great way to enjoy fruits when they're not in season. Fruit is packed in water, juice, or syrup. Syrup adds a lot of unwanted calories from sugar. A cup of pears in heavy syrup has 33 grams of sugar, even when drained. That's more than two tablespoons of sugar! Compare that to a cup of pears in water, which has 15 grams sugar.
Bottom line: Choose fruits packed in water or juice, and drain fruits packed in syrup.
