When it comes to a great all-around food to build muscle, the trophy goes to salmon. It is loaded with protein and omega-3 fatty acids, two key nutrients to build and repair muscle tissue, and to keep your hunger in check. You can also cook salmon several different ways. Salmon is also rich in key nutrients, such as selenium, Vitamin D, B12, niacin and vitamin D. The list goes on with all of the health benefits associated with salmon, such as reducing cholesterol and improving memory. If you were not into fish – some people are not – you could go with grass-fed beef.
