Eating fatty fish decreased the lipophilic index in people with impaired glucose metabolism or coronary heart disease, according to a study. The lipophilic index is considered a marker of cell membrane fluidity, and a low lipophilic index indicates better membrane fluidity.
A low lipophilic index was further associated with larger mean HDL particle size and higher concentration of large HDL particles, which suggests cardiovascular benefit.
Previous studies have suggested that long-chain omega-3 fatty acids in fish have a beneficial effect on cardiovascular risk. Camelina oil is rich in alpha-linolenic acid, which is an essential omega-3 fatty acid whose associations with membrane fluidity are not known.
The researchers used data from two randomized clinical trials to study the effects of fish and camelina sativa oil intake on the lipophilic index. The first study included 79 men and women with impaired glucose tolerance. The second study included 33 men and women with cardiovascular disease.
Study participants were randomly divided into four groups for a 12-week intervention: the camelina oil group, the fatty fish group, the lean fish group, and the control group in the first study. In the second study, subjects were randomly divided into the fatty fish, lean fish, and control groups for an 8-week intervention. The lipophilic index was calculated based on erythrocyte membrane fatty acids in the first study, and serum phospholipid fatty acids in the second study.
In both studies, eating four meals of fatty fish per week reduced the lipophilic index, which indicates better membrane fluidity. Better membrane fluidity has been associated with lower cardiovascular risk. Better membrane fluidity as measured by the lipophilic index was also associated with larger HDL particles, which have also been associated with a lower cardiovascular risk. Eating lean fish or camelina sativa oil did not affect the lipophilic index.

Vegetarians and vegans can find supplements with EPA and DHA that were not derived from animal sources, but they are expensive.
For vegetarians, at least there are some eggs that have extra DHA, but it’s not much, unless you get
That is, “unless you get higher listed amounts, which can be above 200 mg per egg).”
Will canned tuna work?
It has a tiny amount:

Bkmk
Does tuna count? Only fish I eat or like.
Have you tried canned salmon?
Meh, in a salad once. I got sick off a BBQ’d salmon once and never tried it again.
You need to try it again.
Look for red salmon in a can, if possible. A form with the skin tastes best, and has the most Omega-3s.
In general fattier fish are “better” than lean fish, and the fat in a fish is often found just under the skin.
Salmon is one of the best for “healthful” fat content. Tuna “counts”, but it is one of the more lean fish.
Thanks. I take supplements that work pretty good.
One plant-based oil - camelina oil - if I read this accurately.
But I’m left wondering about flax seed oil..
15% is overly generous and on the high side of research for ALA, but after all these years vindication is moot.
Still unresolved is the matter of cooking temperatures vs. viable omega-3. I maintain that poorly cooked fish is nothing more than fish-flavored chicken and that supplements are snake oil.
