Parent Essential Oils (PEOs): The DIFFERENCE
I am often asked how my EFA-based recommendations differ from those of others. The
answer is simple but very significant. The term “Essential Fatty Acids” is being misused
so frequently that I was forced to coin a new phrase, Parent Essential Oils (PEOs).
This term, “Parent Essential Oils,” refers to the only two true essential fatty acids:
parent omega-6 (LA) and parent omega-3 (ALA). The term “parent” is used because
these are the whole, unadulterated form of the only two essential fats your body demands,
as they occur in nature. Once PEOs are consumed, your body changes a small percentage
of them—about 5%—into other biochemicals called “derivatives,” while leaving the
remaining 95% in parent form.
This is crucial for you to understand. There are a host of omega-6 and omega-3 oils being
sold as EFAs that are not EFAs, but rather nonessential derivatives such as EPA, DHA,
and GLA. Fish oils are made up almost exclusively of omega-3 derivatives. Scientifically
and biochemically, calling derivatives such as EPA, DHA and GLA by the term “EFA” is
wrong. Derivatives are not EFAs because they are not essential—your body has the
ability to make them from the parent forms as needed. My research has shown that
supplementing with the derivatives so commonly found in the marketplace and
mislabeled as “EFAs” can easily be harmful to your health.
Don’t make the common “EFA mistake” by unknowingly substituting derivatives for
parents! Since the term has become so confused by so many it is time to focus on the
essence of what they are and why they are so vital to our health and wellbeing.
