I remember the day I decided to become a pescetarian well, despite being only 12 years old. I had already declared my protest of meat and poultry to my parents but the topic of seafood had not been discussed, or frankly, even considered yet. I didn’t realize that when I announced I was going to be a vegetarian that this would mean giving up my beloved seafood. Until….New England Clam Chowder.

Back in my childhood and pre-teen years, clam chowder was my favorite food. I grew up vacationing in the summer with my family on the Cape and in Boston and this is where my love of chowdah flourished (how serendipitous that I would end up moving to New England six years later and staying for 11 years and counting). In fact, one summer, I made up my own chowder competition where I would order clam chowder at every restaurant we went to on the Cape and declare my favorite at the end of the vacation (yes, I was the one and only judge). So it only makes sense that one afternoon when my Mom and I went out to lunch and I saw clam chowder on the menu that I freaked. “Mom, does being a vegetarian mean I can’t have seafood anymore?!?!” My Mom, who was already skeptical about my decision to go veg, saw this as a golden opportunity to encourage another source of protein and nutrients in my carbohydrate-heavy (pop-tarts and bagels) diet. “No, honey. Of course you can still have seafood. You love clam chowder so much, you shouldn’t have to give that up.” PHEW. And so a pescetarian I became.

Now, as a registered dietitian nutritionist, I’m so happy that seafood is a part of my diet. The 2015-2020 Dietary Guidelines for Americans recommend at least two servings (eight ounces) of seafood per week because of its nutritional profile and health benefits. Not only is seafood a good source of protein, it also contains the most B12, vitamin D and omega-3 fatty acids (EPA and DHA) out of all animal protein foods. Eating two servings of fish per week, which provides about 250mg per day of EPA and DHA, is associated with reduced mortality related to heart disease. Other studies show evidence that eating patterns which include seafood are associated with reduced risk of cardiovascular disease and obesity. Plus, the benefits continue for women who are pregnant or breastfeeding! Improved infant health outcomes are associated with pregnant or breastfeeding women who consume at least two servings of seafood per week.

Whenever, I tout the benefits of eating fish to my clients, I’m always hit with the follow-up question: “yeah, but what about mercury?”, so let’s address the elephant in the room. Mercury is a heavy metal that’s found in different species of seafood at different levels. Some species of seafood have low levels of mercury; others have high levels. If you’re regularly consuming more than two servings of fish per week, you’ll want to make sure you’re choosing a variety of seafood that includes choices low in mercury. And if you’re preggers or breastfeeding, you should avoid varieties of seafood that are high in mercury.

Seafood that’s lower in mercury to choose from:

  • Salmon
  • Cod
  • Pollock
  • Shrimp
  • Canned light tuna
  • Catfish
  • Scallops
  • Sardines
  • Oysters
  • Tilapia
  • Haddock
  • Trout
  • Flounder
  • Sole
  • Mackerel
  • Crab
  • Mullet

Given my passion for seafood as part of a healthy (and delicious!) eating pattern, I’m excited to be partnering with Dish on Fish for National Seafood Month in October! Dish on Fish, launched earlier this year, is an initiative geared towards educating the public about the importance of eating seafood at least 2-3 times per week. It’s a pretty robust educational blog, complete with recipes, monthly meal plans and the 411 on seafood nutrition.

As most of you know, I recently traveled to Greece for my honeymoon (post coming soon!) and the seafood there was so fresh and unbelievably delicious that I had to come home and create a Greek-inspired seafood dish. This recipe for Greek marinated salmon is super easy to make – throw your marinade ingredients together and let it marinate for 30 minutes in the fridge, take it out and bake it for 20 minutes and voila – dinner is served! I follow my technique for slow-cooked salmon (low temperature, longer cooking time) for the ultimate restaurant-like medium texture. This Greek-inspired dish is topped off with my favorite beet tzatziki (which was a huge HIT at my birthday brunch this past weekend, btw!)

  2. In a medium bowl, whisk together lemon juice, olive oil, oregano, garlic, mustard, salt and pepper until combined.
  3. Place salmon inside a gallon-sized ziplock bag and pour marinade over top. Make sure salmon is fully coated with marinade and let sit for 30 minutes in the refrigerator.
  4. Remove salmon from marinade, place on parchment-lined baking sheet and discard excess marinade.
