What is the relation between kosher and healthiness? G-d wants us to eat properly but also to be healthy. For example, it is better to try not to eat too much meat (even if it's kosher), and more vegetables and fruits.

So does kosher mean we are eating healthy?

As @shmuelbrin said, no. But there are other laws in the Torah that do cover being healthy. For example: "ushmartem es nafshosechem" is the commandment regarding self-preservation, which includes eating healthy. –  HodofHod May 1 '12 at 16:56

Not necessarily.

There is a misconception that Kosher food is more healthy than non-kosher. However, poisons can be kosher, while perfectly healthy salads with some dead bugs are not.

The laws of Kosher ensure one's spiritual health rather than his physical one.

Besides for the metaphysical aspect of one's spiritual health, there is also the possibility that the kosher diet prescribed by the Torah, at least on a simple level, is for the purpose of self-discipline along with ensuring that Jews don's associate with non-Jews over meals consisting of foods that very well may have been popular amongst the neighboring non-Jewish nations at the time. Also, perhaps the demonstration that we only eat (and wish to be associated with) the more tame, non-carnivorous variety of animals. –  jake May 1 '12 at 17:25

Sefer Hachinuch 73 says (in my own loose translation, and with emphasis added):

Among the bases for this command [of not eating an animal that was slaughtered and then found to have been close to death] is as follows. The body is a receptacle for the soul; through the body, the soul does its work. Without the body, the soul's work can never be completed. That's why it enters the body: for its own benefit (for God only does good, never bad). The body in the soul's hand is like the tongs in the blacksmith's, with which he makes things.

Now, when the tongs are strong and well-aligned so it can grasp the items, the blacksmith can make good things; otherwise, the items being made will never come out good and nice. Likewise, when the body is missing anything, the intellect suffers accordingly. Therefore, the Torah banned all things that cause the body detriment. Along these lines we can explain simply the Torah prohibition on all forbidden foods; and if there is any among them such that we (and the doctors) don't know the damage they cause, don't be shocked: the Doctor who banned them is wiser. How foolish and confused is he who thinks the only damage in something is that which he comprehends!

Know further that it's for our benefit that the damage in these foods was not revealed to us. For people would then arise who consider themselves very wise and say "oh, that damage? That's only damaging in that climate, or for such people". Lest people be fooled by this, the inherent damage was not revealed to us.
