Where does one get the DV% that one needs? And are those % about surviving or thriving? There is literally no definitive place to get such information that is actually backed by science and data.

For instance, that 260% protein you cited is about half the protein I take in a day.

Also, FYI, the danger in taking in too much protein is very much overblown. I doubt you could actually consume enough protein to make it a problem unless you had a medical problem with your kidneys already.
