Imagine the evolution of a relationship, when the delight in discovering a new lover is followed by the discovery of his or her issues, which eventually leads to the relationship being reassessed, however painful this might be.
I speak here about seafood, discovered by many only in the last few years. It’s a fresh new food that widely expanded the choices previously available. It is tasty yet light, and widely known as good for one’s heart and brain.
But then, the novelty of seafood gradually decreased as it turned out to have health issues, legal issues and ethical issues.
You may have read about the health issues, which are quickly summarized here: while the benefits of fish-derived omega-3s, widely touted as good for the heart, are dubious and in many cases not markedly superior to those of nuts, flax seeds or leafy greens, the role of fish as a source of mercury, dioxin and other pollutants is well established, and can reach very high levels of concentration in some species, notably tuna and farmed salmon.
