I think the WHO wasn't intentionally lying here - the other examples appear to be cases where a truth was hidden in order to promote/protect a product (lobbying for sugar to be considered a health food for example). We do need to be critical of what's told as truth in social or personal circumstances, for sure. I just sincerely doubt the WHO intended to harm people by making that claim.
