If you choose jams or jellies made from fruit that don't have excess fructose and do not have added fructose listed on the label then they should be safe. Most berry jams & jellies will be safe. Be careful of grape jam.

These jams list "fruit syrup" as the first ingredient (for example here are the ingredients for orange marmalade). A call to consumer relations revealed that "fruit syrup" included apple and pear syrups which are high in excess fructose. These jams/jellies are probably not a wise choice for individuals with fructose problems.

I buy mine from the Amish farm, so there is no brand on it. But, it is just fruit, homemade and delicious. I have never had any problems with any jam or jelly, even store-bought. Guess I am lucky like that.
