> Fish bad I've read an archeological analysis of a merchant ship rowers-slaves -- every skeleton had perfect teeth. Because slaves were fed only fish, not any bread, bread was a product that merchants traded, while fish was cheap and abundant. So I think "fish bad" opinion was just because fish was cheap and everyone had it.
