Tuna is a type of saltwater fish that can be found in many areas around the world, from the Atlantic Ocean to Indonesia and is one of the most popular varieties of seafood in the world. So why is tuna so popular? Because of its delicious meaty flavor but more importantly because of its many health benefits that we will explore below!
Tuna contains high levels of Omega-3 fatty acids. Omega-3 fatty acids are a type of polyunsaturated fat that is essential to our health, but our body cannot make from scratch. Therefore, we need to get them from the food we eat and/or from supplements. The Omega-3 fatty acids present in tuna may help to reduce LDL (bad) cholesterol levels that can build up in the arteries (blood vessels that carry oxygen-rich blood from the heart to the rest of the body). Research from studies shows that eating more Omega-3 fatty acids is linked with reduced rates of cardiovascular (heart) disease such as heart attacks.
Omega-3s are also very important to our eye and vision health! One type of Omega-3 fatty acid is called DHA (docosahexaenoic acid) and this makes up the retina of the eyes. The retina is the thin layer of tissue that lines the back of the eye.
The Omega-3 fatty acids in tuna can also help reduce inflammation in the body. Chronic inflammation is considered bad for our health and is linked with diseases such as heart disease.
Weight Loss Support
Tuna is what we call a lean meat by being high in protein but low in calories. Did you know that a 4-ounce serving of white tuna has only 145 calories and over 26 grams of protein? This means that it can help us feel full for longer while providing essential nutritional benefits!
Tuna contains the Vitamin B12 that plays a vital role in making our DNA, producing new red blood cells and preventing anemia. Anemia is a health condition where the body does not have enough healthy red blood cells to transport oxygen around the body and can lead to feeling tired and weak.
Tuna is an excellent food source of Vitamin D. Only 3 ounces of canned tuna provide us with 50% of the recommended daily level of Vitamin D. Vitamin D is very important to help keep our bones, teeth and muscles healthy. It also helps support our immune system that fights infections and disease and it is needed in childhood for optimal growth.
Tuna also contains many other vitamins and minerals essential to our health, including:
- Iron: iron is a mineral that is essential for the proper function of hemoglobin that transports oxygen in the blood around our body
- Vitamin B6: we need this vitamin to ensure the normal functioning of digestive enzymes (that break down food), to keep our skin healthy and to produce red blood cells
- Potassium: potassium is a vital mineral in our body because it helps regulate muscle contractions, fluid balance and nerve signals from our brain to the rest of our body
- Selenium: we need selenium in our body for the proper functioning of our thyroid gland, for reproduction, for DNA protection and to protect our body from infection
- Iodine: iodine is used by our body for bone and brain development during pregnancy and infancy and to produce thyroid hormones that control our body’s metabolism
