Which of David's books have you read? The answers to your questions are all in Sweet Poison Quit Plan.

• Bread is generally low in sugar, except of course, raisin bread and finger-buns etc, which have sugary stuff on top. Are you a member? Breads are listed in the members area of this site.
• Since you make the dessert rather than buying it, just substitute 2 measures of glucose for each measure of cane-sugar.
  
• You need about 10 grams of fructose a day. You an get that from two small pieces of fruit, about 100g each. Avoid fruit juice . .  it's concentrated fructose and is like drinking fat!
  
• There are only two criteria that matter: (1) you feel full at the end of every meal, and just don't want to eat any more; (2) your weight is stable at an appropriate level [BMI below 25].
  
• If this is not so, I  suggest you keep a log of every gram of fructose you ingest over a one or two week period. Then you can see what changes you need to make.The tables in David's books will help you.
• It's also a good idea to avoid processed foods as far as possible. But at least read the labels carefully and avoid anything with more than 2% "sugars"  or 2% " polyunsaturated fat". The latter is often not mentioned. But subtracting saturated fat from total fat will give you a rough idea.  "%"  means "grams per 100 grams" . . .  just ignore "grams per serving"
  

Good luck . . .  or should I  say, good management :-)
