The Mighty Omega-3 Fatty Acids

Understanding Omega-3s

Omega-3 fatty acids are a type of polyunsaturated fat that our bodies need but can’t produce on their own. This means we must obtain them from our diet. Among the various types of omega-3s, the ones that particularly steal the heart health show are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Types of Omega-3 Fatty Acids

Omega-3s come in different forms, each with its own benefits. EPA and DHA, found in fatty fish like salmon, mackerel, and sardines, are renowned for their cardiovascular perks. Another type, alpha-linolenic acid (ALA), is primarily present in plant-based sources like flaxseeds, chia seeds, and of course, walnuts.

The Heart-Healthy Connection

Omega-3s are like superheroes for your heart. They swoop in to tackle inflammation, regulate heartbeat, and keep your blood vessels healthy and relaxed. By doing so, they contribute to a lower risk of heart disease, heart attacks, and strokes.
