Health of foods using a number or color system

People understand colors and numbers. Colors would provide a quick way of
knowing how healthy the food we are eating is. It is a pretty simple
concept. It is just up to the FDA & USDA to decide what foods get what color
or number.

I image saying to my kid(s), "You're only allowed to eat the healthy foods.
That means no red (4) or black (5)." We using rating systems ALL the time:
PG13, terrorist threat ORANGE, 87 Octane.

The idea is really to unconfuse people about certain foods actually being
really not very good for you. For instance I see this can of soup. The
packaging appears like it a health food but it really isn't. It full of
salt, carbs, and fat. If I show the orange rating, maybe I won't have
purchased it.

I hope someone important finds this idea useful.
