Finding Sustainable Seafood



Chinook salmon are joining the increasingly long list of fish at risk for extinction. The article Chinook Salmon Vanish without a Trace explores why the Pacific Salmon season is likely to be closed for this year.

Due to several colliding factors, salmon can not keep up with the high demand for one of the most often recommended sources of omega-3 fatty acids.

It's a familiar scenario; throughout the world many fish stocks are being depleted at an alarming rate. And much of our available fish contain unsafe levels of toxins. For much of the population, it is unsafe to regularly eat old standbys like tunafish anymore.

Farmed fish are not necessarily the answer. These fish have varying levels of omega 3’s depending on what they are fed as well as varying toxins depending on where & how they are raised. Farmed fisheries are also suspect for putting the wild fish population in danger when they escape; introducing weaknesses into the gene pool.

Obviously we need to do our part to preserve this precious resource, but how do we make sustainable seafood choices?

Luckily, others have done much of the work for us. The Environmental Defense Fund has created a free, online resource and printable pocket brochure that is available here to help us navigate some of these very issues. (I've used the brochures in cooking classes and with clients and have gotten good responses.)

Other options exist. Fish get there omega-3’s from algae, and though our bodies are not efficient at converting the shorter chained omega-3’s (like the ALA found in plants) into the longer chain omega 3's (like the DHA found in fish), we can also get omega 3's from plant foods. Flax, walnuts, pumpkin seeds and thier respective oils are all good sources of omega 3 fatty acids. Also consider that eating grass fed animal products (like grass fed meat, milk, eggs, and dairy) can be an important source of dietary omega 3's. The animals naturally convert the grass into healthful nutrients. Eatwild.com is a great resource for sourcing grass fed animal products.

Bottom Line
Choose your fish wisely to preserve fish-stocks for generations to come and to avoid eating too much mercury or PCBs. And look for other sources of omega 3 fatty acids to include in your diet as often as possible.

This is a very timely post as I'm on a new seafood diet... I see food, I eat it! Get it. It's a joke. Anyway, check out my new blog:
