High protein cereal bar

It can be a quick option, but a bar on its own is often a small, sweet breakfast. Have it with a piece of fruit and milk or plain yoghurt to make it more filling.

Look at the ingredients to see what supplies the protein: common choices include milk or soya protein, nuts and pea protein. Compare the sugars and saturated fat as well as the protein, since bars can differ a lot.

Keep them sealed in a cool, dry cupboard, away from direct sunlight. A chocolate-coated bar can soften or melt in a warm car or bag.

For a simple British-style snack, have one with a piece of fruit and a mug of tea or coffee. You can also crumble it over yoghurt for a crunchy topping.

The high-protein cereal bar has 30 g per 100 g, compared with 6.25 g in a regular cereal bar.

Milk, soya, peanuts and other nuts are common ingredients, and some bars may contain traces from manufacturing. Read the ingredients and allergen information each time you buy one; UK food businesses must highlight regulated allergens.

Mix oats with nut butter, seeds and a little honey, then stir in protein powder and press firmly into a lined tin. Chill until set, then cut into bars; keep them in the fridge in a sealed container.
