Hi
@Erin Your question seems to be phrased rather opaquely.
Type 2 Diabetics need only to consider Carbohydrates rather than sugar. However if they are on medication (such as Insulin or Glic) that can cause hypos, then they will need either glucose tablets, jelly babies or something else fast acting in order to get them out of a hypo state. These tend to be sugary foods.
However they will also need something slower acting (starchy) if it's at night in order to keep them safe from further hypos as their medication continues to reduce their BG while asleep.
In the UK fibre is automatically subtracted from the Total Carbs (unlike the USA) so during the day all carbs should be treated more or less equally (unless you have tested them with a BG meter and know that certain ones don't affect you so much as others do). Sugars, like whole grains are just forms of carbs and so low carb means low sugar, but low sugar doesn't necessarily mean low carb because starches like flour, potato etc are carbs.
