Salmon made out list for a number of reasons, but the biggest has got to be because its so densely stuffed with omega-3's. These fatty acids are thought to slow memory loss as you age and boost heart health by regulating heart rhythms and keeping arteries and veins supple and free of blockages. While saturated fats lead to obesity, the polyunsaturated fatty acids in fish appear to correct and prevent obesity, according to a study published in Clinical Science.
And that's just the tip of the iceberg. Salmon is also an excellent source of protein. A three-ounce cooked serving contains 20 grams-making it ideal for building muscle and trimming fat. Besides helping stimulate your metabolism three to four times more than carbs or fat, protein is the absolute best food for helping fill you up, so you take in fewer calories and burn more. And that's what being a fit food is all about.
