While it is somewhat recently that experts are starting to agree that
fats are important to our diet, it seems that we cannot agree on which
fats are good or bad (aside from transfatty acids/hydrogenated fats).

For the past 40-50 years or more we've been hearing that unsaturated
fats are good, and saturated fats are bad.  Unfortunately most of
these unsaturated fats ended up being processed in such a way as to
make them more unhealthy than saturated fats.

Now that everyone's on the kick that fresh cold pressed omega-6 and
omega-3 oils are best, we're hearing that saturated fats (especially
the previously evil tropical coconut and palm oils) are healthier than
unsaturated fats.

Who is right?  Should we be consuming flax and hemp seed oil, or
coconut oil?  Or a little of each?

Where is the real science? ;)
