It just depends.
I haven’t seen whatever you mentioned, but maybe I will.
Research has shown that 5 servings of fruits and veggie a day decreased all mortality.
Protein is variable because of age, mass, and activity.
I think for a lot of things you can get what you “need” from food. But the RDI is basically what you need to not be deficient. A lot of vitamins you can take a lot more than the RDI amd it will have additional benefits. Obviously there is still a limit and some are easier to “overdose” on than others. It’s something I would recommend looking into. Vitamin C for example is something you can’t overdose on and it may be good to take far more than the RDI but again you should look into it yourself and determine what’s best for yourself from your research.
