Omega-3 is polyunsaturated fatty acids that are vital for the human body. They affect regulation of the blood pressure, the blood’s ability to coagulate, and helps strengthening the body’s immune system. Our bodies can’t create these on their own, so we have to get them through our food.
Fish contain a lot of these fatty acids, and those found in fish are actually considered the ones that have the most/best effect on your health. Fish also filled with vitamins A, D and E, where D is extra important when it comes to building a strong bone structure.
The most important minerals in fish are iodine and selenium. Lacking iodine could potentially lead to disturbance in the thyroid, and selenium is an antioxidant that is great for the immune system and protects you from free radicals.
In fish you will also find zinc and magnesium. Zinc is involved in oxygenation and immune systems, while our nerve and muscle cells are dependent on magnesium to function.
Fish are generally very nutritious foods, which means that it contains a large amount of nutrients per calorie. It gives us high-quality protein that the body can easily absorb. Protein also helps us building new cells in the body, and keeps us feeling full and satisfied longer.
