Bucket List

I am not known for my love of the outdoors. I appreciate nature and the comfort of the indoors. However, I will never forget my first time in Bass Pro Shop. I was just hanging out with my dad one afternoon and he suggested we go there. That store is like an amusement park for mountain men. I was impressed. I was probably equally excited about that store as I would be in Nordstrom during their anniversary sale. Weird, I know, but there are so many cool gadgets and little useful tools. Who knew so much thought went into outdoor activities. It made me feel like I could survive a week long camping trip, in a tent. Anyway, this store became particularly useful to me when I realized something on my bucket list was to physically catch, gut, scale, cook, and eat a fish. After reading the Omnivore’s Dilemma, I realized that if you choose to eat meat, you should experience what it really means to eat meat. Meat is not just food. It is an animal that was once alive, living, just chilling, until it was killed, so that you could eat it.

The key concept here is that YOU didn’t have to kill it. You just BOUGHT it in a grocery store; lifeless, guilt-free, packaged, ready for you to cook up and eat. It’s not the same as buying a loaf of bread or a bag of chips. In reality, if you had to kill that animal yourself, you’d probably think twice about eating a steak. I mean, would you want to slit a cow’s throat and butcher it?! I’m not trying to get all animal rights on you, but killing animals is kind of a big deal when you have to do it yourself.

Anyway, I’ve chosen to eat fish. So I think it’s only right that I experience killing my own fish at some point in my life.

To be honest, I started eating fish before I knew about any of its health benefits. I genuinely love the flavor of fish. If you don’t like fish, that’s fine, but you should keep reading because there’s still valuable information in here for you.

Fish is good for you. It is inarguably better for you than red meat, pork, shell fish, crustaceans, chicken, turkey, or any other meat. The American Heart Association recommends that you eat fish two times a week. It doesn’t make that recommendation for any other animal product.

The obvious benefits of fish, like tuna salmon, herring, halibut, and bass, are the healthy omega-3 fatty acids. The omega-3 fats have shown to dramatically decrease your risk for heart disease and heart attacks. They’re also beneficial for reducing your risk for stroke, inflammation, triglycerides, and even increases insulin sensitivity.

So there’s no argument that omega-3’s are good for you. Omega-3s help the heart. Everyone knows it. It's cool, but that was so 30 seconds ago. What interests me about omega-3s are their positive influence on brain function. EPA and DHA (two long chain omega-3 fatty acids) produce substances that protect our brain and its cells. Several studies have showed that EPA and DHA may benefit those with ADHD, autism, dyslexia, depression, bipolar disorder, and dementia, and promote optimal brain development in babies. This is a big deal. The food we eat can influence the functionality of our brain. When our body breaks down and metabolizes DHAs, the metabolites or byproducts, function to enhance cognitive performance.

My class-five vegan friends would like to argue that you don’t need to eat fish to get your omega-3’s; they would say you can get your omega-3’s from seaweed, walnuts, flaxseeds, and other plant sources, and they are correct. “Fish get their omega-3’s from seaweed,” a vegan may argue. Well yes Vegan, that’s true, but do you know how much seaweed you would have to eat to get as much omega-3s as fish? More than I’m willing to eat in a day.

Let me explain a little further. There are 3 types of omega-3’s. There is alpha-linolenic acid (ALA, which are 18 carbon fats), eicosapentaenoic acid (EPA; a 20 carbon fatty acid), and Docosahexaenoic acid (DHA, a 22 carbon fatty acid). ALAs are found in plant foods like walnuts, flaxseeds, and canola oil. EPA and DHA fatty acids are only found in fish and microalgae.

Studies show that ALA omega-3s do not show the same neurological benefits as the DHA omega-3s. When we eat ALA our body has enzymes that can convert ALA to EPA and DHA (by adding additional carbons). While our body is able to convert some ALA to DHA, it is not nearly as much as we need to see the protective neurological benefits. Studies show that about 5% of ALA gets converted to EPA and less than 0.5% of ALA is converted to DHA. On the other hand, when you eat DHA, it is easily converted backwards to EPA and ALA in its necessary amounts.

So someone eats 1 oz of walnuts, that one ounce of walnuts has 2.5g of ALA, of that you'll get 125mg EPA and 12.5mg DHA, and the Academy of Nutrition and Dietetics recommends you get about 500 mg of DHA a day.

When it comes to heart health DHA/EPA still show better protective benefits than ALA. ALA is proven to improve platelet function, inflammation, and cholesterol, but DHA/EPA actually decreases the risk of death from various heart conditions. ALAs are still good for you, so continue to eat your flax meal and walnuts, but as far as brain function and development goes, DHA is what you want. Studies show that DHA omega-3s can change gene expression involved in the brain, prevent oxidative stress, inflammation, and cell death in the brain, and benefit brain growth and development. And like I said before, this is not the case with plant-based ALA omega-3s.

But what about the mercury and PCBs in fish? Okay, valid point, so avoid shark, swordfish, king mackerel, and tilefish because those are high in mercury. You can choose fish low in mercury. The American Heart Association and Academy of Nutrition and Dietetics still recommend that fish is eaten at least twice a week. And as far as I’m concerned, it seems like everything is contaminated with something unless it’s “organic,” and even then, who really knows.

So to sum it up, if you wanna be vegan, that's fine, but I suggest you take a microalge supplement to get your DHAs. The studies so far show that DHAs are the most beneficial omega-3 for heart disease and brain function. I'm all about prevention; if you have crazy running in your family, I think it's about time you start fighting off those bad genes with some DHAs.
