The stats don't show straight cream being associated with lower risk of diabetes. Maybe the food surveys don't have anyone eating cups of the stuff though. Who knows?
I usually get the regular cream. I've read though that almost all dairy cows are mostly grass-fed? One time they had a fancy organic cream without any stabilizers, and it tasted super delicious. Unfortunately, haven't seen it since :( Must've been a limited time thing.
The study from 1943 is in adipose tissue. The Omega Quant results are membrane phospholipids. These pools of fats are of very different composition, so you can't make a direct comparison.
I'd like to get some type of database up and running to have some standards of comparison around Omega-Quant tests.
Yes, I think so. Or rather I suppose both get mixed together, the fat from my adipose tissue and from my food intake probably gets mixed up, and both gets used? So over time, as I continue to eat near-zero PUFAs, AA and LA should go down. That's my theory at least.
I understood PUFA is preferentially burned so it might be always PUFA dominant unless you're a human candle. And then we should get a piece of your adipose tissue to be analyzed instead of blood.
Right, that's my understanding, too. So basically we're kind of in the dark while there's PUFA from any source - body fat or food intake. But since I'm taking in very low PUFA in my food, the fact that there's still PUFA used seems to indicate it's coming from my body fat.
So as I lose weight, the PUFA from that fat will be burned, and hopefully not restored (cause I'm not eating much new PUFA). Therefore the PUFA % should slowly go down over time?
Could I desaturate if the PUFA % is going down over time? I am not aware of a way to directly measure the D6D (is that what you mean by desaturase?) But the GLA/LA ratio seems to be a proxy for its activity.
I test with OmegaQuant every July and have a similar profile as you. I have results from July 2021 and July 2022, and already have my test in hand for July 2023. Weight-wise I'm 220 5'10" and although I've fluctuated a bit, I was about the same those years. So I have a few observations.
In July 2021 I wasn't eating super great - kind of a lazy keto with plenty of interruptions. My Omega 3 was 3.1%, Omega 6:3 ratio was 12.1 (at the far end of the OmegaQuant range) and my AA:EPA was off the charts at 85.1.
After weightlifting a lot in winter 2021 into early 2022, I had gotten up to 240 (I always gain a lot when lifting). I stopped lifting so much and went on a high protein, lower calorie diet. By July 2022, my Omega 3 was 4.6%, Omega 6:3 was 9.2, and AA:EPA was 21.8. Interestingly, although my numbers had improved quite a bit, I was around 225, about 5 pounds heavier.
2023 has been an interesting year where I did a lot of fasting because of a stressful event (allergic reaction to a medication) that developed into gastritis. I dropped down to 205 during the worst of the gastritis (it was painful to eat) but slowly reverted back to 220 eating normally to satiety. I'm still pretty restricted in terms of the food I can eat (no pepper/spices/acid/vinegar/caffeine), but I eat salmon almost every day, so I think my Omega 3s will increase quite a bit. Other staples are ground beef, pork sausages, eggs, bacon (yes I know this has omega 6s), home fermented yogurt with L Reuteri, bananas (important for the gastritis) and some occasional toast (I need it for my electrolytes).
Any predictions on where the numbers will go? My Omega 3s will almost certainly go up with daily salmon consumption, but I'm wondering what will happen to that AA:EPA ratio in particular.
What was your AA/EPA/LA in 2021? My last test I got a 33% AA, leading to an AA:EPA of 116. I thought that must've been a measurement error, since my OmegaQuant was so much lower only a few months later. But if you had 85, maybe it could be some short term AA spike? Not sure what would cause it though.
I suppose fish will up your EPA and therefore your AA:EPA will go down? Maybe unless you overdo the bacon.
This test is missing one of the more interesting types of fat, which I would expect to be high for you given your cream consumption: https://en.wikipedia.org/wiki/Pentadecylic_acid
Interesting, I'd never even heard of it!
Surprising given your diet is filled with it! I learned about it after reading this article from The Atlantic about ice cream potentially reducing the risk of diabetes: https://www.theatlantic.com/magazine/archive/2023/05/ice-cream-bad-for-you-health-study/673487/
The stats don't show straight cream being associated with lower risk of diabetes. Maybe the food surveys don't have anyone eating cups of the stuff though. Who knows?
Curiously, it's not only not in the OmegaQuant test, it's not listed on my favorite Wikipedia page:
https://en.wikipedia.org/wiki/Butterfat
I read about that study when it came out. Maybe there's something uniquely protective to dairy after all?
Are you consuming cream from grass-fed or grain-fed cows? The omega-6/omega-3 ratio is quite different:

I'll have to try the Omega Quant sometime. Thanks for reporting on it!

Yeah, man. Keep motorin'. I'm close enough to dipping under 200lbs that I expect it'll happen within 2 weeks. Progress feels GOOD!
Haha it does, doesn't it :)

Yes, the first test you took looks very wonky!
Yea, a database would be cool. The reddit thread is pretty decent already but hard to get an impression of what a good goal would be.
Do you have any "aim for this target" numbers for D6D index and SFA/MUFA/PUFA? Or any other interesting ones.
Are these numbers not reflecting the mobilized fat you burn during weight loss? Ergo; not what you eat now?
Yes, I think so. Or rather I suppose both get mixed together, the fat from my adipose tissue and from my food intake probably gets mixed up, and both gets used? So over time, as I continue to eat near-zero PUFAs, AA and LA should go down. That's my theory at least.

Unlessss you... Desaturate. Is there a way to measure the desaturase?
Could I desaturate if the PUFA % is going down over time? I am not aware of a way to directly measure the D6D (is that what you mean by desaturase?) But the GLA/LA ratio seems to be a proxy for its activity.
I was thinking of SCD1.
I didn't know of the trajectory of PUFA results in you - if it's going down then I think you're in good shape, pun intended.

I suppose fish will up your EPA and therefore your AA:EPA will go down? Maybe unless you overdo the bacon.
In 2021 I had
AA: 9.5%
EPA: 0.11%
LA: 19.11%
2022:
AA: 13.6%
EPA: 0.63%
LA: 19.41%
I hadn't looked at it like this before. Seems most of the 2021 to 2022 effect is from the EPA increasing. I don't really know what to make of it.
Hm your AA numbers are way more reasonable (no 33% nonsense). So maybe mine was an error.
EPA up is good, right? So you're on the right track?
True, its getting better slowly. Will post when I get the new results.
Here's the 2023 results:
AA: 13.5%
EPA: 1.05%
LA: 19.33%
Continuing to make progress on Omega-6:Omega-3 ratio at 5.8 and AA:EPA at 12.9. Basically I've moved from deep red territory to yellow!
Nice! Almost same w6:w3 like me, I had 5.7 :)
I do wonder how much the ratio matters vs. just cutting out w6 after a point.
