Fish is among the healthiest foods on the planet. It is loaded with important nutrients, such as protein and vitamin D. Fish is also the world's best source of omega-3 fatty acids, which are incredibly important for your body and brain. They are high in many nutrients that most people aren't getting enough of. This includes high-quality protein, iodine and various vitamins and minerals. However, some fish are better than others, and the fatty types of fish are considered the healthiest. That's because fatty fish (like salmon, trout, sardines, tuna and mackerel) are higher in fat-based nutrients. This includes the fat-soluble vitamin D, a nutrient that most people are deficient in. It functions like a steroid hormone in the body. Fatty fish are also much higher in omega-3 fatty acids. These fatty acids are crucial for your body and brain to function optimally, and are strongly linked to reduced risk of many diseases. To meet your omega-3 requirements, eating fatty fish at least once or twice a week is recommended. Fish is high in many important nutrients, including high-quality protein, iodine and various vitamins and minerals. Fatty types of fish are also high in omega-3 fatty acids and vitamin D.


Fish is generally considered to be among the best foods you can eat for a healthy heart. Not surprisingly, many large observational studies have shown that people who eat fish regularly seem to have a lower risk of heart attacks, strokes and death from heart disease.


Researchers believe that the fatty types of fish are even more beneficial for heart health, because of their high amount of omega-3 fatty acids. Eating at least one serving of fish per week has been linked to reduced risk of heart attacks and strokes, two of the world's biggest killers.
