I didn't realize science expired after N years. Should we disregard the theory of gravity, too? I mean, it's quite old!

Your first two sources (NHS & Choose My Plate) are literally government/industry propaganda, so aren't even worth taking seriously.

The Harvard page doesn't say, "carbs are evil". It says, "The type of carbohydrate in the diet is more important than the amount of carbohydrate in the diet, because some sources of carbohydrate—like vegetables (other than potatoes), fruits, whole grains, and beans—are healthier than others."

Where does it say to limit carbohydrates on the other pages? They all say to increase fruit and vegetable consumption, which are almost all "carbs". I'm genuinely puzzled and intrigued by why some people think carbs are so bad, at least in the form of whole plant foods.
