your calcium carbonate has sucrose?? what is it, a TUMS or something?
don't get discouraged dc, it's a learning curve, and you're on it, you'll only come out better off in the end. this kind of thing is the reason i have issues with diets per se, the individual interpretation can be so highly variable..
i'm searching nutritiondata for fruits lowest in sugars, and once you get out of avocado/lime/lemon-land, in ascending order selected fruits include raw blackberries, strawberries, guavas, bananas, kiwis, papaya, and by that time you're up to 30g of sugars per 1c serving. if you let it go up to 35g per 1c serving, you can include grapefruit, blueberries, pears, cherries, oranges
for comparison, fruits and veg with high sugar content are up over 50g per serving.
veggies up near 30g of sugar per serving include (now in descending order): tomato, squash, carrots, turnips, peppers, celery, cucumber, onion.
veggies with 20g per 1c serving and under (also in descending order): things like cauliflower, pumpkin, peas, asparagus, spaghetti squash, sweet potato, savoy cabbage, mushrooms (raw crimini), parsnips.
veggies on the lower end (under 5g per serving) include: mushroom (grilled portobello), yams, potato (hmm, take that with a grain of salt), garlic, alfalfa, lima beans, spinach, collards, parsley
just for kicks, i went to the profiles for kale and chard, both have 2g. not sure why they didnt come up in the list above. maybe i read too quickly.
anyway. chin up! knowledge is power
