Coffee may be good for you

Visit your dentist regularly. Brush and floss your teeth properly. Avoid sugary foods.

Oh, and drink plenty of black coffee.

Wait, what?

That's what a new study, "Antibacterial effect of coffee: calcium concentration in a culture containing teeth/biofilm exposed to Coffea Canephora Aqueous extract" seems to indicate.

Researchers found that coffee with high amounts of caffeine can destroy bacteria that causes plaque.

They used bacteria in the saliva to cultivate biofilms in fragments of milk teeth that were donated by children.

Then, they applied an extract of the coffea canephora, also known as Robusta coffee. Other studies have shown that coffee has high levels of polyphenols, compounds that are known to prevent and treat oral diseases.

But forget about the benefits if you take yours with sugar, milk or cream, because those will help the bacteria grow.

And, don't drink too much black coffee which will stain your teeth. Plus, the acid in coffee can hurt your enamel.

Oh, and did we mention the researchers were from the Federal University of Rio de Janeiro, Brazil?

Brazil happens to be one of the major producers of Robusta coffee, along with Vietnam and Africa.

Perhaps we need to take that cup of coffee with a grain of salt.
