We have some wonderful halibut fillets in the freezer – not cheap, but worth it. Halibut is truly a nutrient-dense food. A very good source of high quality protein, halibut is rich in significant amounts of a variety of important nutrients including the minerals selenium, magnesium, phosphorus and potassium; the B vitamins B12, niacin, and B6; and perhaps most important, the beneficial omega-3 essential fatty acids.
*Essential fatty acids are so named because they are essential for our health but cannot be made by the body; they must therefore be obtained from foods. Cold-water fish like halibut are a rich source of the omega-3 essential fats, a form of essential fatty acids in which the standard American diet is sorely deficient.
