Raw steelhead trout is a relatively lean, protein-dense food that contains about 58 calories per 3-ounce portion (22 from fat), 7.6 grams of protein, 59 grams of cholesterol and no carbohydrates. Other nutrients include 143 milligrams of potassium, .6 grams of Omega 3 fatty acids and significant amounts of vitamins D, E and B12.
Although at first glance steelhead trout seems high in fat and cholesterol – at 4.6 and 59 grams of fat per 3 ounces – like other fish and seafood, it contains significant amounts of Omega-3 fatty acids as well as small amounts of monounsaturated and polyunsaturated fats, which promote cardiovascular health.
Another benefit of eating steelhead trout is its high protein content per serving, particularly for people who need to add more protein to their diets while keeping their total fat intake low. In addition, steelhead trout is relatively high in antioxidants such as vitamin E and B12, which help boost metabolism and produce red blood cells, DNA and RNA. B12 also supports the health of the immune and nervous systems and may also lower the risk of developing certain types of cancer. Selenium, another antioxidant, is important to the healthy function of endocrine glands such as the thyroid.
