What are toxins?

Answer 1

Both the previous answers are correct, but toxins most commonly are discussed as substances found in food, due
to human intervention and your body has no idea how to deal
with them and so sticks them in your fat cells to be dealt with
when it has more time, but it never does, because we keep dumping more junk on top of it. When you are losing weight,
your body dumps these toxins back into your blood stream
and if you dont flush them out by drinking plenty of fluids, the
body will try to reabsorbe them and poison you.

Answer 2

A toxin (Greek: τοξικόν, toxikon, lit. (poison) for use on arrows) is a poisonous substance produced by living cells or organisms. Toxins are nearly always proteins that are capable of causing disease on contact or absorption with body tissues by interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their severity, ranging from usually minor and acute (as in a bee sting) to almost immediately deadly (as in botulinum toxin).

Biotoxins vary greatly in purpose and mechanism, and can be highly complex (the venom of the cone snail contains dozens of small proteins, each targeting a specific nerve channel or receptor), or relatively small protein.
