Do fruits and vegetables have the same amount of nutrition if they are not fully ripe or tasteless?

I've noticed since a lot of fruits/vegetables are being grown on a massive scale on "factory farms" they get to the store unripe and don't have much taste. I try to buy organic and from the local farms but they can't supply all I want through the winter. I don't mind too much the loss of flavor IF I'm still getting the benefit, but if there's no benefit AND no taste....seems pointless.
