>Raw egg white has a antivitamin which destroys the vitamin biotin.
>Biotin deficiency usually results from raw egg whites.

ingested  by themselves alone  like in the studies  certainly!
Egg yolk is rich in biotin so lot of chance that the whole egg is not a
problem.

I  am  eating  them raw for over 12 years  and eat them whole  when the
white is tasty , but  end up eating more yolks than white at the end ( after
2 or 3 eggs the white become unappealing generally to me ) .
If the eggs are eaten mixed with other foods it might be wiser to discard
the white because you will not be able to have an instinctive response to it
, If you eat eggs by themselves ( one little hole at both ends and   suck
the inside) let your sens of taste decide. The white at time is very welcome
to me ( may be because of its mineral content ? it rehydrate me when fresh
water can't
