What did you read about the RDA that gives you no faith in nutritional
information? I thought the measurements were reasonably accurate.
For starters, they changed the food pyramid.
A quick web search returned about a thousand food pyramids. So, you
get to pick and choose depending on your goals or illnesses.
Second, their advice to eat a variety of foods within each group (and
even going by colors) seems to be another way of just telling us to
eat a bunch of different foods, but less of some types than others, in
the hope that we'll stumble upon what we need. It's a "throw
everything at the wall and see what sticks" approach, that shows a
lack of precision and understanding.
There are many different nutritional factors, and some that may not be
discovered or the amount that should be ingested.
I'm seriously considering ignoring that thing entirely.
I don't think that pyramids form a very good guide, it's better to
focus on the essential nutrients. Because there are more nutrients
needed than different types of food that can be eaten in a day, a few
supplements can balance things out. (FWIW, linear programming
techniques can solve the problem, but it would be difficult to
construct the diet).
