Chocolate for a healthy heart.
Not that we even need a reason to eat chocolate, however the
antioxidant benefits of cocoa or cocoa-containing products has been reported
extensively, but how is this clinically relevant? Well, for those struggling
with weight, metabolic or inflammatory conditions, cocoa and cocoa-based
products may hold the key to the prevention of a range of signs and
symptomologies.
Cocoa has been indicated in a range of papers to potentially
reduce cardiovascular disease and improve cardiovascular-related risk factors
such as blood pressure, low-density lipid oxidation, inflammatory status and
the blood lipid profile, all of which are common features of metabolic
conditions.
Now, before we start consuming bars of chocolate, much
discussion is around which flavonoids exert particular functions and activity.
Recently, researchers conducted a trial in an effort to identify the
lipid-altering properties of cocoa. The result? theobromine.
Theobromine, a
cocoa flavonoid, was found to have significant influences on HDL and LDL
cholesterol concentrations, demonstrating the ability to increase the former
and reduce the latter. Studies have shown that increasing HDL cholesterol by
just 1% is linked to a 1-3% reduction of cardiovascular risk. This makes
theobromine a promising dietary ingredient in the prevention of cardiovascular
disease. However, the dosage of theobromine needs to be taken into account for
its efficacy. 850mg of theobromine daily was found to have largely significant
lipid-altering effects; this equates to 100g of dark chocolate or 200g of milk
chocolate.
For the chocoholics out there this may sound ideal, but as
we know with this large consumption of chocolate comes the extra calories and
saturated fats – not ideal for those with metabolic issues. For those who
utilise food-as-medicine it is interesting to note that 6g of cocoa equates to
approximately 150mg of theobromine.
This research brings us one step closer to understanding the
health benefits of cocoa, and reveals theobromine as a potentially interesting
supplement and dietary intervention for those with cholesterol-related health
concerns.
