                                According to the Food Standards Agency, UK food packaging is legally required to display energy values in both kilojoules (kJ) and kilocalories (kcal). This confirms that yes, the UK does use kcal, and understanding this system is key to accurately interpreting food labels, particularly for visitors or those new to tracking nutrition in the country.
