Reading nutrition facts labels is indeed a must for everyone and athletes neglect this too relying on their trainers and nutritionists.
The labels are there for a reason. Most food manufacturers do abide by the guidelines they are supposed to abide by but getting as close to the borderline as possible.

If an athlete or anyone eats two portions of such food they may already be putting themselves where they don’t want to be – in health threatening situation – if they do this long term.
