                                Over half of a standard jar of jam is sugar, and since it is derived from fruit, yes, jams have fructose. This sweet component comes from both the natural fruit content and, in many cases, added sugars like sucrose or high-fructose corn syrup, significantly increasing the overall fructose level.
