Dark chocolate is an antioxidant-rich superfood that can help reduce your risk of heart disease and can even help improve your mood.
In terms of our teeth, dark chocolate is one food you don't need to avoid. Studies have shown that dark chocolate can help fight cavities, plaque and tooth decay.
Dark chocolate is a good source of polyphenols, natural chemicals that can limit bacteria in your mouth. They can also help to neutralise microorganisms that cause bad breath.
Studies have also shown that eating a small amount of dark chocolate each day can increase blood flow to your brain and help with cognitive thinking.
We don't recommend over-eating dark chocolate though. Make sure you stick to the recommended serving amount.
