What does be it mean in this context and what kind of sentence is this? (grammatically)
There is no one in our society who is not ethnocentric to some degree, no matter how liberal and open-minded he or she might claim to be. People will always find some aspect of another culture distasteful, be it practices, a way of treating or relatives, or simply a food that they cannot manage to get down with a smile.

This is a use of an old way of phrasing things called a concessive subjunctive clause, as explained in this answer. You can tell because of the inversion of subject and verb and the switch from a present-tense verb form.
These days you are most likely to see concessive subjunctive clauses in fossilized phrases like this:
It means the same thing as this does:
So in your examples, it’s just like saying that:
CGEL 1985 says of concessive clauses:
In olden times, clauses contrary to expectation took a different verb form than the normal one. Most such uses today are of a somewhat “elevated” register, be that one of literature or poetry, or sometimes of oratory or legal regulation. The previous sentence is an example of this, using a subjunctive construction under inversion.
But you don’t have to do it that way. Concessive clauses often start off with subordinating conjunctions like though, although, even though, even if, whether, no matter, unless, lest, or any of the various wh- + ever words like whatever, whichever, however, whoever, wherever, and all the rest of that ilk.
As one might guess from the occurrence of unless and even if in that list, they can be thought of as serving as the protasis — meaning the “if” part — of a conditional. The big difference is that they are assuming the negative of the verb they are governing, something “contrary to expectation”.
As such, concessive clauses historically took the subjunctive form of the verb, not the normal one. You see this frequently enough in the Early Middle English of Shakespeare and the King James Version. For example, Job 13:15 reads:
Notice that’s “he slay” in the subjunctive, not “he slays” in the indicative. In casual conversation today, we would be much more apt to either put that in the indicative or use a modal auxiliary. For example:
Even if he should slay me, yet will I trust in him.
Even if he slays me, I will still trust in him.
The old conjunction lest still takes a subjunctive or modal:
Lest there were any doubt left, the plaintive showed the jury the brutal scars scoring and crisscrossing his back.
Lest there be any doubt left, the plaintive will show the jury the brutal scars scoring and crisscrossing his back.
Lest there should be any doubt left, the plaintive will show the jury the brutal scars scoring and crisscrossing his back.
Another way of forming an English conditional is to skip the conjunction altogether, but employ inversion and either a subjunctive or modal:
Which just means:
So you get inverted versions in the present, too, when making such concessions:
Be it for good or for ill, I will have it no other way.
Should it be for good or for ill, I will have it no other way.
If you use a conjunction, you don’t need any inversion, but the old-style way can still take a subjunctive:
However, by using an explicit concessive conjunction, we can get it back to a normal present tense formulation:
No matter whether it’s for good or for ill, I won’t have it any other way.
Even if it’s for ill, I’ll have it no other way.
Most of the inverted subjunctives of concessive clauses today occur in fossilized phrases and are no longer productive. You don’t often hear people today talk like this any longer:
I will always be there for you, come what may.
Say what he will, I shall never believe him.
It would be more casual and less poetic to instead say:
No matter what happens, I’ll always be there for you.
No matter what he says, I’ll never believe him.
Returning at last to your original quotation, it could also have been worded this way instead:
These really all mean the same thing. It just sounds a bit more high-falutin’ to use the “be it” version of the concessive subjunctive clause that your original has in it.
