Hello ladies.
The sweeteners used in vegan recipes are Maple Syrup, Agave Nectar, Dates, Date Syrup, Coconut Sugar and Date Sugar. I've used them all except Date Sugar because I couldn't find it on sale anywhere. I have no idea about calorie content but I do know that eating whole Dates does not cause a rapid rise in blood sugar because the fibre slows digestion.
Hope this is helpful ladies.
Take care everyone.
