SP tracker has a 3 3/8" pomegranate as 105 calories, and 26.4 grams of carbs.
I think most fruit/veggies are where you want to get most of your carbs from. You don't fill out your tracker, so people can't see what other carbs you eat, and suggest where esle you might cut some carbs, but you know what you eat, so you probably should track it, but if not, look at your carbs, and make some decisions.
I wouldn't eat a pomegranate, because it has 25 g of sugar. I would eat applesauce, or berries w/whipped cream to get my fruit. Much less carbs, and sugar. However if you just need to cut down a bit, then you probably have hundreds of grams of carbs to cut from, and finding 50 grams should be possible from other sources, allowing you to enjoy your pomegranate. I am sure it is at least as healthy as most food options that the average person eats.
