Mr Gill points to the prevalence of hypertension and diabetes in Grenada and across the Caribbean as another legacy of slavery. I tasted Grenada's delicious national dish called Oildown. It's a one pot dish, which was all slaves were able to cook, made of pigs tails and salted fish and breadfruit high in carbohydrates. Centuries of poor diet have led to high rates of chronic disease, argues Arley Gill, and investments in education and health by the former colonial powers would go a long way to undoing some of this damage.
