Seafood is an extremely nutrient-dense food, one that should be consumed frequently if at all possible and affordable.
Dr. Weston A. Price, the “Charles Darwin of Nutrition” and author of Nutrition and Physical Degeneration, found that seafood eating cultures exhibited the most vibrant health of all the traditional cultures he studied during his journeys around the world in the 1920s and early 1930s.
Seafood clearly is superior to the meat from land-based animals as the nutrient density of the meat and dairy of land-based animals is highly dependent on whether they are grass-based as well as the richness of the soil the animals graze upon.
Many consumers are unaware that around 80% of the seafood available in the USA now comes from developing countries like Thailand, Vietnam, Costa Rica, and others where the farming practices are frequently suspect and, in many cases, downright unsafe. For example, fisheries in Asia sometimes even raise their fish in sewage! Antibiotics and other carcinogenic chemicals are nearly always added to the water to reduce the chance of infection in fish raised in crowded, unsanitary conditions.
If you choose to eat seafood as I do, make sure you always get wild-caught salmon and other seafood from cold, northern waters, or at the very least, seafood farmed in the USA, where these unsafe practices and chemicals are banned.
Note that sustainable salmon is not necessarily the same thing!
The short video below provides a chilling overview of the farmed fish problems throughout the developing world and why you must be savvy in your seafood buying habits in order to protect your family and your health.
Also note that almost all the fish and seafood available at restaurants is farmed! One night at dinner at Bonefish Grill, I asked the waiter which items on the menu were wild caught. To my dismay, there was not a single wild item to choose from! It seems that steak is your safest and most nutritious bet when eating out.
