Essential fatty acids (EFAs) are “essential”. Our body can not make these fats. EFAs must be obtained by eating certain foods and taking dietary supplements. You have heard the term, saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and unsaturated fatty acids (PUFAs). EFAs are a type of PUFA categorized into one of two classes: Omega-6 or Omega-3. The essentiality of two of these omega fats, linoleic acid (LA, an omega-6), and alpha-linolenic acid (ALA, an omega-3) is because humans, do not have the enzymes to make them from other fats in the diet. We get them from eating animals that have consumed plants and have now accumulated them in their body fat stores.
Aim for at least 4 grams of omega-3s, which you can easily get from food and supplements. I take the Standard Process General Health Daily Fundamentals packets which contain tuna omega-3 oils.
Think of your supplements as insurance!
