If you eat them a bit on the green side vs very ripe, the sugar content should be lower I would think..
I've read that a bit green is healthier overall... don't have time to search for facts or links right now though..


For any food , how you cook it makes a big difference too in the health factors..

steam, boiled , baked vs fried, coated with butter or sauces...
Or microwaved - various thoughts on the good and bad of it.. electro magnetic fields - I was just reading about that EMF stuff again.. I still use our Microwave but move away 10' or so as often as I can when using it..

And seasonings too, the seasoning mixtures and pre made sauces & soups, so many of them have MSG in them.. yuck..
