Fats with Benefits
For  years,  the     mainstream  thinking    about   fat     sounded     like    a   line    that    could
appear  in  a   nursery rhyme—Don’t want    to  be  fat?    Better  not eat fat.    But that
statement    is  actually    false   on  two     levels.     You     need    fat.    As  one     of  the     three
macronutrients, it’s    a   pillar  of  well-balanced   nutrition.  Your    brain,  for instance,
is  composed    of  60  percent fat (we are really  “fat    heads”),    so  you require the
dietary kind    to  support memory  and clear   thinking,   and your    body    uses    fat as
energy  throughout  the day.
The trick   is  to  get fat from    the right   sources,    because dietary fats    come    in
several  forms.  The     ones    you     really  want    are     found   in  the     foods   listed  above
because they’re unsaturated fats.
Saturated   fats    are solid   at  room    temperature (think  butter),    and they’ve been
associated  with    heart   disease.    (Red    meat    contains    saturated   fat but this    can be  a
tricky  area,   because grass-fed   cattle  deliver some    healthy fat,    but red meat    also
contains    a   compound    called  L-carnitine,    which   may lead    to  clogged arteries.)
Small   amounts of  saturated   fat appear  to  be  okay.   I   don’t   want    you to  obsess
about   counting    nutrients,  but the recommendation  is  no  more    than    7   percent of
your    total   diet    should  come    from    saturated   fats—that’s 14  grams   on  a   2,000-
calorie day.
