Fruit cooked down with sugar: a tablespoon on toast adds about 56 calories. On the energy-density scale, 278 kcal per 100 g puts jam at the high end.
A typical serving (1 packet, 14 g) has about 39 calories, and 100 g has 278 kcal. Calories scale with weight, so double the portion means double the number.
There are 0.4 g of protein in 100 g of jam, which works out to about 0.1 g per serving (1 packet). Treat it as an energy source rather than a protein source.
Sugar comes to 48.5 g per 100 g, so 1 packet (14 g) delivers roughly 7 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 169641 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
