Every food gets one of four bands, and the band tells you how much.

What decides the band is how close the food is to the state God created it in, and how much of what your body is actually built from is in it.

That is why animal foods sit at the top. Humans ate at the top of the food chain for thousands of years, and meat, fish, eggs and dairy carry those nutrients in the form the body can actually use. Plants and grains are welcome. They are just not what you are built from.
