Human body needs different types of fat for a variety of functions including producing energy, keeping the body warm, cell growth, protecting the membranes, absorbing other nutrients and producing important hormones. Omega-3 fats regulate hormones that impact our heart rhythms and inflammation. Chronic inflammation is a potential cause of cancer.
Why do Omega-3 fats could prevent heart disease?
Cardiovascular health: Omega-3 fats are essential for producing hormones responsible for regulating important cardiovascular functions such as blood clotting and heartbeats rhythm (contraction and relaxation of artery walls to pump blood), resulting in decreased risk of stroke and heart failures.
Why do Omega-3 fats help prevent breast cancer?
Omega-3 fats also help reduce inflammation by inhibiting enzymes that help produce hormones responsible for inflammation. While inflammation is a necessary physiological response to help injured tissues heal, it can also harm our bodies when it’s triggered or continued improperly, causing chronic inflammation. Obesity or being overweight can lead to chronic inflammation. In Chronic inflammation, the immune system is overworking to the degree that it can cause overproduction of certain cells and proteins and changing the way our body tissues function. This type of uncontrolled growth can turn normal cells into cancer cells. According to a cancer prevention research, obese women seem to have a higher risk of breast cancer than women who maintain a healthy weight, especially after menopause. Chronic inflammation can be the explanation for this trend.
What are some good natural sources for Omega-3
Our bodies can create most fats from scratch using other fats and ingredients; however, omea-3 fats (also known as Omega-3 acids or n-3 fats) are an exception. Our bodies can’t produce these essential fats and need to obtain them from foods high in Omega-3. There are three types of Omega-3 fatty acids: ALA (alpha-linolenic acid), DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). The preferred sources are DHA and EPA, which are best for your heart health. Our bodies can turn ALA into DHA and EPA but it’s more efficient to get them from the right food sources. Wild, fatty fish with low levels of mercury is the best source for DHA and EPA. Wild Alaskan salmon, herring, mackerel, tuna, sardines, and anchovies are all good sources. ALA is found in rich concentrations in plant sources, including certain vegetable oils, flax seeds and nuts such as walnuts.
