Some very basic questions given my complete dearth of knowledge:
What are micro-nutrients and anti-oxidants? Why are they good?
What is the minimum quantity of vegetables a normal adult would need to get the benefits described? Do they scale at all with increased consumption?
micronutrients are a subset of "vitamins and minerals" that we only need in small amounts. Your body uses them for physiological processes, but doesn't make them. If you don't get them, the physiological processes they are involved in stop working.
Oxygen is a very oxidizing agent. It used to be a metabolic biproduct which was toxic to most life on earth, until one branch of the tree of life evolved to use it for metabolism. We and most other successful organisms are descended from that branch. Even though we've evolved defenses to counter oxygen...

Also, I have a new "stupid" question.
