Yeah, this reads like popular health guidance left over from the 1980's. Back then we though that "fat makes you fat" and shifted to sweeteners to make food taste good. Later, we found out that was all due to the sugar industry.
Indeed, lots of anti-fat researched was sponsored by sugary drink companies.
But the jury is still against too much saturated fat, since the lymphatic system doesn't handle it in the healthiest of ways. So limiting saturated fats is still the WHO recommendation.
