OK, it might not be a 'ban' in strict grammatical terms, but the implication is clear. Because of these guidelines many people have treated any dietary fat as taboo. I certainly counted myself among them. Decades of advice and ad campaigns from the government will do that.

I believe these guidelines and associated ad campaigns (and many like them in other countries such as the UK) have actually led to people 'learning' to find fat completely distasteful, so I think it will be some time before there is a significant change in eating habits.
