The benefits of eating fish go far beyond their delicious flavours. Many varieties are sources of high-quality protein, antioxidants, vitamin D, minerals, and varying levels of omega-3 essential fatty acids – not to mention that fish is low in saturated fat. On the flip side, concerns about mercury and polychlorinated biphenyls (PCBs) are legitimate and need to be considered when selecting fish.
Whether you’re new to buying fish, or planning to eat it more often, here’s what you need to know:
Health Canada and the American Heart Association recommend eating at least two servings of fish per week  . One serving of cooked fish is 75 g or 3.5 oz, and it is considered healthy to eat up to 340 g or 12 oz per week when you choose varieties with low-mercury levels (as listed below). 
Be Aware of Contaminants
Contaminants, such as mercury and PCBs, become more concentrated in fish the higher they are on the food chain. This means that certain types of fish are higher in contaminants than others.
- Tuna, fresh or frozen
- Canned albacore tuna
- Orange roughy
It’s alright to eat these fish on occasion, but experts recommend that you limit your intake to the following amounts:
- Adults: 150 g per week
- Women who are pregnant or breastfeeding: 150 g per month
- Children 5–11 years: 125 g per month
- Children 1–4 years old: 75 g per month
Polychlorinated biphenyls: PCBs are another contaminant found at low levels in some larger varieties of fish with higher fat contents, particularly farmed salmon. The most effective way to reduce your intake of this potential carcinogen is by choosing wild salmon over farmed varieties .
A fantastic choice is Wild Alaskan Salmon Oil. It is made from 100% wild Alaskan Salmon and contains naturally occurring ratios of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in addition to naturally occurring levels of astaxanthin and vitamin D.
Certain fish and shellfish contain higher levels of omega-3 fatty acids because of their own diet. For the greatest health benefits and safety, choose varieties that are recognized for their omega-3 concentrations and lower levels of mercury and PCBs. Delicious options include: 
- Atlantic mackerel
- Rainbow trout
- Lake Whitefish
- Blue crab
If you’re looking to boost your omega-3 intake safely, but want the convenience of a softgel, RoyalRed® Omega-3 Krill Oil is a high-quality choice. It is verified as pure, potent, and sustainable, with no fishy aftertaste. Krill oil is a fast absorbing source of EPA and DHA in addition to the antioxidant astaxanthin.
