Scores use the government's 2018 nutrient profiling model, calculated per 100g from the nutrition panels and ingredients on Ocado's M&S listings. Points are added for energy, saturated fat, free sugars and salt, and taken away for fibre, protein, and fruit, vegetable, nut and seed content. Foods scoring 4 or more are classed as less healthy.
Fruit, nut and seed content is taken from the percentages declared in each ingredients list, so cereals that do not declare them score zero for it. The model scores what a cereal is made of rather than how much you eat.
