Researchers have found a way to make chocolate more flavourful and nutritious with greater levels of antioxidants. Chocolate is known to have health benefits. It can potentially lower blood pressure and cholesterol and reduce stroke risk. Cocoa undergoes several steps before it takes shape as a candy bar. Workers cut down pods from cocoa trees, then split open the pods to remove the white or purple cocoa beans. They are fermented in banana-lined baskets for a few days and then set out to dry in the sun. Roasting, the next step, brings out the flavour.
