Recently a new study from the University of
California, Berkeley, has made a rumbling in the world of health and fitness.
This study found that, in mice, the element copper, inhibits the effects of the enzyme
PDE3. PDE3 itself inhibits the effects of a messenger molecule known as cAMP. cAMP is
needed to activate the enzymes responsible for mobilizing fat cell. Think of it as copper
being a crossing guard. It stops the PDE3 cars, allowing cAMP pedestrians to cross the
road to the… fat burning factory? Ehh… you get the point.
The main takeaway of this study, especially for science nerds, is that copper ultimately
can be classified as a signaling element. It’s long believed that the only signaling
elements in the body were that of electrolytes, such as sodium, calcium, and potassium. Copper
might perhaps be added to this prominent list. Now before you go running off and buying copper
supplements or food high in copper, do know that you only need very small amounts to reach
your daily intake. The recommended intake for the average adult is roughly 0.9 milligrams,
which can be easily met by eating seafood, kale, mushrooms, beans, and nuts. Supplementation
usually isn’t necessary unless you have a high copper deficiency to begin with.
And even if copper does play a role in fat metabolism, the process of fat burning is
by and large still regulated by your hormones. Ask any other questions about health and fitness
topics that you’ve recently heard about on the news. Thanks for watching!
