We compared these five mueslis (we were advised by nutrition expert Robert Gorgos from Formkante.de):
Dr Oetker Vitalis Chocolate Muesli
600 grammes, 2.99 euros
Dr Oetker's chocolate muesli has the most sugar. "More sweet than breakfast," says expert Robert Gorgos. It is therefore not an ideal meal for athletes. Nevertheless, muesli is suitable after sport because it quickly replenishes your reserves thanks to its high carbohydrate content. However, due to the high fat content, you are better off with cornflakes. Chocolate muesli is impractical as a source of energy before training.

Kellogg's Cornflakes
375 grammes, 2.49 euros
The classic. But also for athletes? Yes, says expert Gorgos. Cornflakes are particularly suitable as a recovery meal with milk or yoghurt. They contain a lot of carbohydrates and quickly replenish your energy reserves. They are less suitable before the tour because they only provide short-term energy. Add fruit here too. "It doesn't have to be the expensive cornflakes from Kellogg's, by the way," says expert Gorgos.

Crunchy, grape and nut muesli
1000 gram, 1,79 Euro
The grape and nut muesli from Aldi is the cheapest in the test (1000 g). In terms of content, it scores highly with lots of fibre and ingredients such as grapes and nuts. It is therefore less suitable immediately before intensive exercise - more suitable for afterwards. "To make the most of the nutritional value of the rye and wheat flakes, you would actually have to boil the muesli or leave it to soak overnight," says expert Gorgos.

Kölln oat flakes
500 grammes, 1.25 euros
Oatmeal is ideal for athletes. Especially before exercise. This is because they are extremely nutritious. Even better than preparing it with milk is to boil the flakes with hot water and leave to infuse for a while. This is easier on the stomach lining and is more digestible. "Whether it's expensive rolled oats or some from the discounter - it hardly makes a difference," says our expert Gorgos. Lots of content for little money. Top.

P. Jentschura Morgenstund
1000 gram, 17,50 Euro
Morgenstund is not a typical muesli - it's porridge. It has to be infused with boiling water. In terms of nutritional value, it comes out on top in the test. Thanks to many important ingredients that are ideal before intensive exercise. Morgenstund tastes almost neutral - so it must be enriched with fruit, nuts, etc. And it's expensive. "The cheaper and almost equally good alternative is oatmeal," says expert Gorgos.
