I shall recount a little bit of history.
When the Spaniards “discovered us” five centuries ago, the estimated figure for the population of the island did not exceed 200,000 inhabitants, who lived in harmony with nature. Their principal sources of food came from rivers, lakes and seas rich in proteins; they additionally practiced a rudimentary agriculture which provided them with calories, vitamins, mineral salts and fiber.
The habit of producing cassava, a kind of bread made from yucca, is still practiced in some regions of Cuba. Certain fruits and small wild animals complemented their diet. They brewed a drink with fermented products and contributed to world culture the in no way healthy custom of smoking.
