Where do you go to find accurate food composition data?

This was the question Dietitian, Elise Kelly asked herself when she moved to the UK.

Roughly 75% of countries have their own food composition datasets[1]. These unique datasets reflect differences in local food varieties, production and fortification policies.

Google displays instant ‘Nutrition Facts’ for certain foods in their search results. But unless you're based in the US, it’s unlikely this data will be from your country's dataset.

Public Health England maintains the food composition data for the UK food supply. It was first published in 1940 by Professor Robert McCance and Dr Elsie Widdowson in response to war-time nutrition needs [2]. McCance and Widdowson’s Composition of Foods is currently in its 7th edition and available to download as an Excel spreadsheet[3].

Why was Nutridex created?

Using the Excel spreadsheet to look up a food's complete nutrition profile takes time. The spreadsheet contains almost 3000 common foods listed in alphabetical order. Macronutrients, vitamins and minerals are split across separate tables and nutrient values are for a set 100g serving size.

Trusted food composition data should be accessible. It should be at the fingertips of every health and food professional.

Nutridex is a free food composition tool that makes accessing trusted McCance and Widdowson’s data easy. Search for foods or browse them by category. When you've found a food, change its serving size to suit and the nutrition tables will update in realtime.
