- Canada’s Food Guide recommends at least two - 75 g servings of fish per week.
Pat MacIntosh, Alberta Health Services - Fish is an important part of a healthy diet for people of all ages. It is an excellent source of protein, vitamin D, and omega-3 fatty acids which help maintain a healthy heart. When pregnant women eat fish, it helps with brain and eye development of the growing baby.
However, some people avoid fish due to concerns about mercury. Most fish is low in mercury and safe to eat. Common examples are Atlantic mackerel, canned light tuna, clams, haddock, herring, oysters, rainbow trout, salmon, sardines, shrimp, sole, pollock (Boston bluefish), and whitefish.
