These people are good at exterminating denial. The next morning, my two breakfast rolls became one. Sugar used to be the focal point for diabetics. The focus has changed now to all carbohydrates, from which the glucose comes. The proper diet for someone with diabetes is an individual thing and it requires close monitoring of the blood glucose level in relationship to food eaten, to find out what level of carbohydrate consumption fits the individual.
Sugar is just another carbohydrate, reckoned into the total.
We learned to read labels to fit any food into our diets. Earlier, people who had diabetes were monitored mainly for the amount of sugar in the blood when they got up in the morning, before they'd eaten. But this gave little or no picture of the fluctuating levels during the day. This can level out to one or two tests at different times of the day. Until the person can know their body's tendencies and formulate a plan of action, more frequent self-testing may be advisable.
