Slogans are meant to be reminders about proportionality not to be taken literally.

To you that may be true. But people are gullible. And they will use those slogans and not bother to think.

I teach a six week life skills class centered around keeping yourself fed every year. Shopping, setting up your kitchen and basic cookery. Most of the students have heard the slogans and take them to heart. Because they do not know any better.

They are surprised how easy, tasty and cheap (comparatively) it is to have a healthy meal at home.
