Carbohydrates from whole grains are different from added sugars and have completely different effects on the body.

This is not what the article tells, this is what you assume. I agree that they emphasize sugar and refined grains, but they also criticize high carbohydrates in general.

> Chronic high carbohydrate consumption — especially of refined grains and added sugars — drives obesity, diabetes, heart disease and other metabolic disorders.

I never denied that they are criticising the high carb recommendation, I'm just saying that is irrelevant to my original comment.

Well I think it’s quite relevant to your comment, because the fear of fat (hence their reduction) lead to the 50% carb recommendation.

I've read the guidelines. They don't say to "fear fat". They say to "limit foods and beverages higher in added sugars, saturated fat, and sodium, and limit alcoholic beverages." The 50% number comes from the fact that the guidelines recommend eating lots of fruits, vegetables, whole grains, and non-red-meat protein foods.

Yes and exactly this recommendation is criticized in the linked article.

The result from a decrease in fat consumption is that the carbohydrates (or proteins) need to be increased. The energy needs to come from somewhere.

So you agree that noone is telling anyone to "fear fat".

Well I don’t think this is the case, typically people are told to eat low fat and high carb. And I agree to this sentiment, as long as your carbohydrate amount is high, it is better to avoid fat. However it seems to me that when reducing carbs way below 50%, to, let’s say, less than 5%, then it’s possible to increase fat.
