Breakfast – the first meal of the day which sets you up for what’s ahead. Ideally you want slow release carbohydrates and some protein, that will keep you going throughout the morning.

A high dose of sugar is exactly what you don’t want – this will result in a release of insulin, which will only be followed by that unpleasant ‘slump’ that chased up the Jelly Tot binge you might remember from junior school birthday parties.

Despite this, we’ve discovered many ‘healthy’ breakfast cereals have up to 35g of sugar in 100g. To put all this in perspective – 100g of plain Sainsbury’s Porridge Oats contain 1.1g of sugar. Of course, these cereals also contain fibre, vitamins and minerals – but we simply can’t overlook such a high dose of sugar.

We’ve sought out some of the biggest offenders. Of course, you’ll likely be adding milk, which contains natural sugars, but to allow for direct comparison we’ve compared all the brands looking at 100g (suggested serving is usually 40-60g) of the raw cereal that you’ll be getting out of the packet.
