Rainbow trout is an excellent source of protein that's low in cholesterol-raising saturated fat and rich in omega-3 fatty acids. One food guide 2.5-ounce (75 g) serving of rainbow trout provides 128 calories, 20 grams of protein, only 1.3 grams of saturated fat, and a total of 8400 milligrams of DHA and EPA, the two heart healthy omega-3 fatty acids. The amount of DHA and EPA in one 3 ounce serving of rainbow trout provides almost double the intake of omega-3 fatty acids thought to prevent heart disease (500 milligrams per day).
DHA (docosahexaenoic acid) also plays a key role in memory and cognitive function. DHA makes up 60 percent of the membranes in the brain, keeping them fluid so that memory messages can pass easily between brain cells. An adequate intake of DHA - from fish like rainbow trout - is particularly important for pregnant and lactating women as they nourish their developing infants. Older adults at risk for Alzheimer's disease can also benefit from increasing their intake of DHA by eating fatty fish like rainbow trout.
A serving of rainbow trout also provides two day's worth of vitamin B12 - eseential for healthy nerves, blood cells and DNA - and also serves up calcium, potassium and selenium.
Canada's Food Guide to Healthy Eating recommends eating at least two servings of fish each week. One serving (3 oz/85 g) of rainbow trout provides the following nutrients:
|Total Fat||5 g|
|Saturated Fat||1.3 g|
|Vitamin B12||5.3 mcg|

Rainbow trout, which belongs to the Salmo family of fish, is closely related to salmon and Artic char - two other fish rich in omega-3 fatty acids.
Steelhead salmon refers to rainbow trout that's found in the Pacific or Atlantic Ocean while rainbow trout is the fish that's harvested or cultured in lakes, rivers and other inland bodies of water.
In addition to being farmed, wild rainbow trout can be fished from the rivers and lakes of British Columbia where they'll grow to be as much as 39 inches long!
Fresh or frozen rainbow trout have the same nutritional value. Your local grocery store or fish monger should have fresh rainbow trout available throughout the year. If you are buying fresh trout, choose a whole or filleted fish that has shiny scales and is firm and slightly elastic to touch. Fresh rainbow trout will have a mild odour but it shouldn't smell fishy.
If buying frozen rainbow trout, avoid any fillets that show signs of brown discolouration or dried out edges. Choose a package of frozen rainbow trout that has little or no air trapped inside to minimize freezer burn.
Wrap fresh rainbow trout in plastic wrap or store in an airtight container in the refrigerator for no longer than one or two days.
For longer storage, label the packaged rainbow trout with the date of purchase and freeze it for up to two months.
Fresh rainbow trout can be baked whole or as fillets. Frozen rainbow trout can be cooked without being thawed if you can spare the additional cooking time. (Thawing frozen rainbow trout in cold water takes about 30 minutes per pound.)
To bake fresh rainbow trout, preheat the oven to 450°F (230°C). Rinse the fish and pat it dry with a paper towel. Place the whole or filleted trout in a baking pan, brush with olive oil and season to taste.
Estimate the thickness of the rainbow trout and bake for 10 minutes per one inch (2.5 cm) of thickness. Flip the trout half way through the cooking time, unless it's less than half an inch (1 cm) thick.
If you're cooking rainbow trout wrapped in foil or sauce, add five minutes to the cooking time.
Rainbow trout that's opaque and flakes easily with a fork is ready to be enjoyed.
Rainbow trout is delicious cooked on the grill or in the oven. Its tender pink flesh cooks quickly and needs little more than a squeeze of lemon juice to add flavour.
