Fat
Several studies have documented
an inf luence of cocoa on fat and
carbohydrate metabolism, as well
as on appetite. A fairly recent
review of research, conducted at
Queen Margaret University, UK,
concluded that cocoa inf luences
the expression of certain genes
involved in fat production in
the body and that it probably
also inf luences hunger. For
instance, when dark chocolate
was compared to milk chocolate,
it was found that the dark variety
resulted in less hunger. Again, all
of this is consistent with studies
that show desirable effects of NO
on fat metabolism. However, with
chocolate, some of the possible
fat loss effects may be as a result
of its rich mineral content. It is
rarely reported that cocoa is a
concentrated source of several
minerals, including magnesium
(which is often found to be
deficient in people’s diets), copper,
manganese, iron and phosphorus.
Increased phosphorus intake has
recently been shown to decrease
body fat in obese individuals.


Other effects


Now, many astute readers may
already be aware of some of these
benefits but there are some other
fascinating effects of cocoa and
these include...


Cholesterol - HDL


and LDL


When it comes to protecting the
heart and blood vessels from
the damage caused by low HDL
(“good” cholesterol) and high LDL
(“bad” cholesterol), cocoa is hard
to beat. It not only moderates the
oxidation of LDL which is the
process that leads to the narrowing
of blood vessels, it also increases
HDL cholesterol levels. This effect
on HDL is especially important for


the fairly significant proportion
of gym-goers who use anabolic
steroids, as these drugs seem to
have their negative effects on the
heart in large part by decreasing
HDL. Also, probably part of this
effect of keeping blood vessels
clear of blockages is the reason
behind chocolate’s apparent
positive effects on the brain, such
as improving cognitive function.

Protects
major organs

Beyond the effects on the heart
and blood vessels, some research
suggests it may help repair liver
damage caused by poor lifestyle
and being overweight. Believe it
or not, a condition called non-
alcoholic, fatty liver disease
(NAFLD), which is caused by
too much eating and not enough
exercise, now causes more
incidences of liver disease than
the abuse of alcohol. Well, it looks
like dark chocolate can protect the
liver from this condition. Similar
to its protective effect on the
liver, it seems to protect kidney
function too. When compared to
white chocolate (which doesn’t
contain cocoa or polyphenols),
consumption of dark chocolate
resulted in significantly better
measures of kidney function.
And again, as with the effect of
HDL cholesterol on the heart,
steroid-using bros are at higher
risk of liver and kidney disorders,
so again, eating dark chocolate
or some form of cocoa could
be a healthy choice.

Type of cocoa
is crucial!
So cocoa clearly has great potential
to improve performance, recovery
and health but one
of the most
complex
aspects

of cocoa is how it reacts when
combined with different nutrients.
Several studies suggest that if you
consume it with certain foods, the
benefits can be altered. As with the
polyphenols in tea (and possibly
wine and berries, etc), some
studies suggest that when you
consume them with milk or other
proteins or fats, they no longer
deliver the goods, or at least they
are delivered differently. On the
other hand, some studies suggest
benefits to combining them with
milk proteins and this is an active
area of research which is trying to
deliver the maximum benefits of
this superfood.
The problem currently is that
some studies suggesting that it is
the casein from milk which may
deactivate the effects but the
effects of the polyphenols have
also been reported to be reduced
by milk fats. They also bind to
components of whey protein
but the consensus is that this
may be a way to enhance some
of cocoa’s effects. Therefore,
until the science catches up and
shows some definitive benefits,
my best recommendation is that
for the health benefits, you are
probably fine to mix cocoa with
whey protein but you should
avoid casein, soy or fat. For the
performance benefits, use dark
chocolate (minimum 70% Cocoa


  • and no, milk chocolate doesn’t
    seem to have these effects) on
    its own or use powdered cocoa
    without any protein or fat. Finally,
    when choosing cocoa, try to go
    with a natural or “non-Dutch-
    processed” or “non-alkalised”
    version and organic varieties
    may also be a better bet.
