The selected numbers are not zero
The native per-bar panels show1.0g sugars for Grenade OREO60g,1.5g for selected Fulfil55g and12g for TREK Biscoff50g. The first two carry low-sugar positioning,but neither displayed value is zero. The TREK record is a different flapjack recipe rather than an equivalent low-sugar chocolate-coated bar.
Use one common basis
If comparing by food mass,the selected per100g sugars values are1.7g,2.8g and24g. If comparing one selected wrapped bar,use the native per-bar numbers. Mixing1.0g per60g with24g per100g would exaggerate the difference in the chosen units. State the basis beside the figure rather than presenting an unlabeled lowest-sugar ranking.
Sweeteners are a separate field
Grenade and selected Fulfil include sweeteners and declare polyols in their panels. A low sugars row does not mean there are no carbohydrates,sweeteners or energy. Nor does a product description involving no-added-sugar chocolate establish a sugar-free whole bar. Read the selected ingredient list and nutrition panel together without inventing a personal metabolic effect.
A shopping-brief example
Suppose a buyer wants a bar whose selected label has a lower sugars value than another shortlisted product. The labelled numbers can support that limited comparison. They cannot establish that a bar is suitable for a person with diabetes,a child,a pregnancy or a medical diet. This site neither collects those circumstances nor converts the sugar difference into a health recommendation.
Finish with the actual wrapper
If sugars or sweeteners determine the purchase,check the current received panel and exact flavour. The older Fulfil record has a different sugars figure and recipe;using it would change the answer. No sugar analysis,tasting,glucose test or personal dietary approval has been performed here. Independent food/nutrition/content review remains pending.
