So I’m researching omega 3/6’s and found some interesting info that I thought I’d dump here. I’ve got a ton of tabs open, and have found info all over so I’ll just supply the basics and if you’re interested you’ll have to do your own research.
Omega 6’s are necessary, obviously…but there are different forms. Most of the oils that I’m seeing people using to get their 6’s in range provide LA - linoleic acid. Apparently, one of the reasons why these oils have been considered no good for us isn’t JUST the high amounts of 6’s in our diets, but also the fact that there are conversion issues from LA to GLA - gamma linoleic acid - which is considered anti-inflammatory and appears to have health benefits. There are apparently many different lifestyle and health issues that can interfere with that conversion, including the other types of oil in vegetable oils.
The truth is most of us don’t properly utilize linoleic acid. There are a number of dietary and lifestyle factors inhibiting the conversion of linoleic acid to GLA: sugar consumption, smoking, alcohol, chemical carcinogens, aging and illnesses (viral infections, cancer, diabetes, hypothyroidism, cardiovascular disease, cholesterol, and hormonal fluctuations).
In addition, there are major metabolic roadblocks which get in the way of the conversion. The main culprits are the “bad” fats: trans-fatty acids from margarine, vegetable shortening and commercially processed vegetable oils.
These are biologically inferior fats, totally incapable of being converted into the powerful GLA. Instead, they actually hinder the very catalyst needed for the GLA transformation, a special enzyme called D6D (Delta-6-Desaturase) and its vital co-workers-vitamin C, vitamin B6, vitamin B3, zinc and magnesium.
So, for many, going straight for the GLA may be more beneficial than looking at vegetable oils for your omega 6’s. Borage oil is said to have the largest amount of GLA. I haven’t concluded my research yet, so I don’t know how much GLA is required daily. g/day of recommended 6’s are pretty high (as opposed to 3’s). I found one recommendation of 12g, but that’s for LA and I’m not sure if those recommendations have taken into account poor conversion of LA to GLA or not. (I’d be interested if anyone comes across that information) When I find it, I’ll post whatever source is cheapest/has the most GLA if anyone’s interested.
