Nestlé KitKat Chunky nutrition

One bar (40g)Ultra-processed (NOVA 4)2 allergens NPM Score (2018): 24, higher is less healthy

Figures from Morrisons product page, collected by Boone. Free sugar estimated by Boone. Last checked 17 October 2026. Data checks are led by Murray Dare.

Free sugar leaves out an estimated 3.5g of lactose per 100g, worked out from the 68.9% chocolate on the label at the legal minimum of 14% milk solids, so the real amount of lactose is likely higher. Lactose is the sugar in milk and is not free sugar.
