High protein snacks and drinks, including yoghurt, porridge pots, cereal bars and milkshakes, are more popular than ever.

But their “health halo” could be obscuring the fact that some of these foods are not really that good for us, an analysis has found.

In fact, some of the snacks could be seen as examples of so-called “protein washing” – when foods are marketed as healthy because of their high protein, when they actually should be eaten in moderation.

The two main shortcomings of such snacks are usually failing to be very high in protein and having more sugar than protein, said Robert Bradshaw, superintendent pharmacist at Oxford Online Pharmacy, which carried out the research.
