Think about it - taste and smell are our methods of detecting chemicals. It seems to me that we've evolved to prefer more flavor, which is why we use so many spices that themselves have health benefits.
When we measure nutritional values, all we are doing is measuring the levels of chemicals that we know about. For example, if we don't actively measure Vitamin C levels, we'd have no idea that oranges have a higher level than ice cream.
The vitamins and minerals we know enough about to look for were generally found as a result of acute diseases brought about by a total absence (pellagra, beriberi). Now we are finding entire classes of chemicals (Omege-3, Omega 6)which have long term effects on health. It's an area of active research and there is a lot of controversy out there. It may never be possible to isolate each chemical and determine its role simply because of the complexity and expense involved (not to mention the interplay among chemicals)!
For now, eat lots of plants, eat moderately, avoid processed foods.
