Calories are per 100g as sold, taken from the nutrition panels on Sainsbury's own-brand listings. Porridge pots are labelled for the pot made up with water; Boone has converted them to the dry contents so they compare fairly. Ranking per 100g compares what each cereal is made of; serving sizes on the boxes vary, so a fair comparison needs a fixed weight.

The percentages under each cereal are for a 30g serving and change with the age and sex you pick, using the estimated daily energy requirements from the Scientific Advisory Committee on Nutrition. Milk is not included; each product page adds it.

Frequently asked questions

Which Sainsbury's own-brand cereal has the most calories?+

Sainsbury's High Protein Chocolate & Nut Granola, with 460 kcal per 100g, or 138 kcal in a 30g serving before milk.

Which Sainsbury's own-brand cereal has the fewest calories?+

Sainsbury's Fruity Muesli, with 339 kcal per 100g, or 102 kcal in a 30g serving before milk.

Why are granolas so high in calories?+

Granola is baked with oil, nuts and seeds, so it packs more energy into each gram than flakes or puffs. The Sainsbury's own-brand granolas average 433 kcal per 100g, against 382 kcal for Sainsbury's Cornflakes.

Does this include milk?+

No. These figures are the cereal alone. Each product page lets you add semi-skimmed, skimmed, whole, oat, almond or soya milk and change the portion.

Where does this data come from?+

The nutrition panels and ingredients lists on Sainsbury's own-brand cereal listings at sainsburys.co.uk, collected in October 2026. Branded cereals sold at Sainsbury's, such as Kellogg's or Weetabix, are not included. Boone works out free sugar, manufactured ingredients and nutrient profiling scores from them.
