Essential Fatty Acids

Fatty acids are an essential part of our diet to help smooth our organ systems. Our bodies cannot make essential fatty acids, so we must depend on food sources or take supplements.

There are two types of fatty acids, namely essential and non-essential. The body can make non-essential fatty acids when it converts amino acids from food sources.

Essential fatty acids are vital for regulating hormones that our body needs for the normal functioning of the immune system and the central nervous system.

Essential Fatty Acids



What are Essential Fatty Acids?

Essential fatty acids are a class of lipids that our body cannot synthesize, so we have to get them through the food we eat. The two essential fatty acids we humans require are Linoleic acid (Omega-6) and Alpha-linolenic acid (omega-3). These are polyunsaturated fatty acids.(1)

Both omega 3 and 6 are crucial for the healthy functioning of our body and its various systems. These essential fatty acids make hormones called eicosanoids that act as nutrients for the body’s nervous system, immune system, and other hormones.

Even though both the essential fatty acids make the same compound, it facilitates different functions. The eicosanoids from Omega-3 fatty acids keep the heart healthy, whereas the same compound from Omega-6 can manage inflammation and blood pressure.

There should always be a balance in the amount of Omega 3 and 6 in our diet. Any excess of these fatty acids may not be suitable for our health.

Conclusion – Essential Fatty Acids Health Benefits

Essential fatty acids are vital for the healthy development of our body, and we can’t synthesize them. But we can get these fatty acids from the food sources that we eat or from supplements.
