The nutrition panel carries the highest density of information on a packet, and is also the part most often misread.

The first trap is the unit. Many products state figures per serving rather than per pack, and a pack often contains two or three servings. When the calorie figure looks low, check that line first.

What "sugar-free" actually means

The second is "sugar-free". Under the standards this generally refers to specific sugars such as sucrose; it does not mean the product is low in carbohydrate or will not raise blood glucose. Starches affect blood sugar too.

Sodium is the one most overlooked

The third is sodium. In processed food it is often the figure that genuinely matters — especially in products that taste sweet, where nobody thinks to check for salt.

  • Unit: confirm whether figures are per serving or per pack
  • Sugar-free: usually refers only to specific sugars
  • Sodium: sweet products can be high in it too
  • Ingredients: listed in descending order by weight

One practical addition: the ingredients list runs in descending order by weight. If sugar or oil appears in the first three, the numbers on the panel are unlikely to look good either.
