Fruits are very much suck it and see, I can manage strawberries blueberries and cherries as long as I keep the quantities down, and half an apple with a meal. Most everything else is off the menu, except for ripe grapes (the kind in a bottle, the grapes themselves are basically bags of sugar water)
I do sometimes eat *small* quantities of dried fruit mixed with larger quantities of nuts, the fat and protein slows down the carbs. The combination can be useful fuel for prolonged walking or gardening.
Prawns are good and especially good with avocado. They contain astaxanthin (so does salmon) which is a very useful chemical. Do heed Sue's warning about gout though. I like to fry them in some toasted sesame oil with sesame seeds and chillies and cashews, and often add other hot spices and other things like peppers, and eat them with a big handful of salad. The only downside is that 85% chocolate goes down soooo well after chillies . . .
