Ananova:

Chocolate should be free on the NHS because of its health benefits for women.

According to scientists chocolate helps cut symptoms of PMT and depression reports The Sun.

Chantal Coady, of Rococo Chocolates, said: "It could be used as a substitute for drugs like Prozac."

Chocolate releases feel-good chemicals called endorphins. It is also full of magnesium, which cuts mood swings, and heart-protecting substances.

The Department of Health said more studies were needed.
