What is omega-3? And what does omega-3 do for our bodies? In this article we’re looking at the reasons why these fatty acids are considered essential to the health functioning of our bodies.
Omega-3 fatty acids are incredibly important. They are an integral part of cell membrane development throughout the body and affect the function of the cell receptors in the membranes. Omega-3 are essential fats, of which the body cannot conjure on its own, but must source them from food.
But what is omega-3? And what does omega-3 do for our bodies? In this article we’re looking at the reasons why these fatty acids are considered essential to the health functioning of our bodies.
Omega-3 are a family of essential fatty acids that play an important role in your body that provides a number of health benefits. There are many types of omega-3’s, but the most important of all of these are ALA (alpha-linolenic acid), DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).
ALA is an essential fatty acid for good health, but our bodies can’t make it, that is why it relies solely on sourcing it from the food that we eat. ALA is primarily found in plant foods such as nuts and seeds, as well as in vegetable oils.
EPA and DHA omega-3 fats are vital for a healthy heart and good blood circulation. Oily fish, such as sardines, salmon and mackerel, are the best source of EPA and DHA. Other food sources with a smaller amount of EPA and DHA fatty acids are white fish and shell fish.
Omega-3s are nutrients you get from food or supplements that help build and maintain a healthy body. They play a vital role in the cell wall structure each one of us has in our bodies. Not only does the body need these fatty acids to function, but they also deliver some big health benefits too. The nutrient is a source of energy and helps to keep our heart, lungs, blood vessels, and immune system working to the best of their ability.
There are many health benefits to consuming a nutritious amount of omega-3 in your diet or as a supplement. Studies have shown that people who regularly consume omega-3 in their diet are less likely to develop high cholesterol than those who have low omega-3 in their diet. There has been a lot of research to suggest that the omega-3 fats and oils, especially EPA and DHA, can help protect the heart and blood vessels from disease.
Omega-3 fatty acid DHA, is vital for brain health and our retinas. It is especially important for pregnant and breastfeeding women to make sure they are consuming enough omega-3, as it affects the health of the baby.
Omega-3, especially as you get older, is one of the best vitamins for women, as it can help with memory, mood and also reduces blood pressure and inflammation. Because of its ability to reduce inflammation, it may help with other health conditions such as heart disease, arthritis, and other age-related joint issues.
