Two legitimate label columns
Per100g values describe a standard food-mass basis;per-bar values describe the selected declared unit. The selected Grenade panel has35g protein per100g and21g per60g bar. Fulfil has36g per100g and20g per55g bar. The first pair suggests one comparison and the second a different ordering because the bars have different masses.
Do not mix the columns
Comparing Grenade’s21g per bar with Fulfil’s36g per100g would falsely make one selected serving appear to contain much more protein than it does. Label the basis beside every number in a shortlist. If a screenshot crops off the column header,return to the full selected panel rather than guessing the denominator from the size of the number.
A buyer’s comparison example
Suppose the question is what one selected wrapped bar declares. Use the native per-bar columns:21g for Grenade and20g for Fulfil. If the question is concentration by food mass,use35g and36g per100g instead. Neither tells this site what an individual should eat,how to meet a medical diet or which bar will improve sporting performance.
Preserve source rounding and conflict
TREK’s panel lists9.8g per50g and20g per100g while its headline says9g. Do not replace the native per-bar figure with a calculated10g and erase the discrepancy. A calculation using rounded label values may differ from another rounded column;the appropriate action is to preserve both and seek the current maker/received-label explanation.
Use the source finder for reading
The local source tool shows the selected native panel bases as read-only references. It does not accept bodyweight,daily intake or disease information and does not calculate a recommended protein allowance. Where the source has a conflict,it shows that conflict instead of returning a personal approval or a supposedly corrected laboratory result.
