We have heard from many health experts that we need to be eating more seafood. Left alone to wade through mercury and sustainability concerns — plus the advantages of Omega 3 fatty-acids — we can become frustrated. A new website, HowMuchFish.com, is here to help.
It's unique because you enter your weight, as well as what size serving you would like to eat. Thus, your results are very specific. You then click on what fish you'd like to eat, and information pops up sharing the nutritional information based on the serving size you choose, as well as how many servings you would need to eat in a week to consume too much mercury.
The site is limited to only 25 fish varieties, though they are the most popular ones in America. I would love to see the website expand its offerings. They also list some fish as "good choices" that I have concerns about, namely farmed salmon and tilapia. The website is also very limited in what information it gives you on a very complex subject. I would recommend educating yourself further by reading information put out by the Monterey Bay Aquarium Seafood Watch.
If you want to know more about my tilapia concerns, you can read Farmed Tilapia: Good for the Environment, Bad for You. It's not meant as a bash toward all tilapia farms, but rather serve as a warning that just because a fish is "sustainable," doesn't mean it's always good for you.
My personal criterion for seafood includes seafood that is low in mercury or other contaminants, is sustainable, and is high in nutrients. I share more about those criteria here. What seafood we personally eat changes according to availability and new information. For example, I was thrilled to start eating oysters for their high nutrient levels. But when I found out that the ones available in my area were gathered from an area polluted with Roundup (a Monsanto herbicide), I gave up the practice.
In other words, HowMuchFish.com is a helpful tool, but it provides limited in information. Use it to your advantage, but don't depend on it solely.
