Fatty fish, such as mackerel, halibut, and the most popular, salmon, are considered very nutritious and high in magnesium as well. A half-fillet, which is 178 grams, has at least 53 mg of magnesium, which is 13% of the recommended daily intake. Moreover, It also has 39 grams of high-quality protein, while being rich in selenium, potassium, B vitamins and a number of other nutrients. Studies have also shown that consuming fatty fish helps in lowered risk of other chronic diseases, such as heart disease. Many of these benefits are due to the higher amounts of omega-3 fatty acids.
