Good side of chocolate
The main reason for the benefits of dark chocolate for our health lies in the high level of flavonoids- powerful antioxidants that (in small quantities) can be found in tea, red wine and apples.
Antioxidants are important because they protect cells and tissues from free radicals, unstable molecules that can change and weaken the cells. We can consider them as a kind of insurance policy against damage caused by stress, poor diet and inevitable ageing process.
Dark chocolate also contains significant amounts of two important minerals; magnesium (which is important for energy productions, strong bones, muscle relaxation and the transmission of nerve impulses) and copper (which helps in the production of neurotransmitters and is associated with a lower risk of developing cardiovascular disease).
Thus, 40g of dark chocolate contains 15% of the recommended daily intake of magnesium and 34% of the dose of copper.
