Reading food labels

Updated 21 October 2026 ยท Based on WHO and NHS guidance

Food labels help you compare products quickly and choose the one that suits you better.

What to look at

  • Serving size: the numbers are often per serving, which may be smaller than what you eat.
  • Energy (calories or kilojoules).
  • Fat and saturated fat, sugars and salt (or sodium).
  • The ingredients list, which starts with the ingredient there is most of.

Some labels use traffic-light colours: more greens is generally a better everyday choice, while reds are fine now and then.

If a label shows sodium rather than salt, multiply the sodium by 2.5 to get the salt.
