Fish oil slows burn of genetic fuse in ageing, say scientists

Omega-3 fatty acids from fish oils have a direct effect on biological ageing, US research suggests

Fish oil may be the true elixir of youth, according to new evidence of its effect on biological ageing. Omega-3 fatty acids from fish oil preserve the genetic "fuse" that determines the lifespan of cells, say scientists.

The discovery, made in heart disease patients, may explain many of the claimed health benefits of omega-3.

Taking fish oil supplements is said to protect against heart disease, improve survival rates after a heart attack, reduce mental decline in old age and help to prevent age-related changes in the eye that can lead to blindness. Research has also shown that rodents live one-third longer when given a diet enriched with fish-derived omega-3.

Although omega-3 fatty acids have powerful anti-inflammatory properties and lower levels of some blood fats, the mechanisms behind these effects are poorly understood. The new research suggests that omega-3 has a direct effect on biological ageing by slowing down the rate at which protective caps on the ends of chromosomes shorten.

The caps, called telomeres, are made from copied strands of DNA and have a similar function to bookends or the plastic ends of shoelaces. They prevent the ends of chromosomes – the "packages" of DNA in the cell nucleus – becoming damaged and keep the DNA organised and contained.

Each time a cell divides, its telomeres get shorter until a critical point is reached. DNA then becomes damaged and the cell stops dividing, and may die. In this way, the telomere acts like a biological fuse.

The rate at which the fuse "burns" can vary both between individual people and individual cells. This is believed to have an impact on age-related diseases.

US scientists conducting the research looked at the effect of omega-3 fatty...

Why isn’t there ever a study that determines Chick-Fil-A is beneficial to your health? I’d be the healthiest man alive, then!

I take 4 capsules of fish oil every day which, I now understand, explains why my FR posts are all so clever and my Alzheimer’s is being fended off.

Interesting. I’ve been a fish nut since I was a kid. I’m 56 and am constantly being mistaken for 40.

Just sayin’...

The Guardian article mentions summer. Might there be a vitamin D link or am I grasping with that?

I have capsules with 1000mg of fish oil and 1000IU of vitamin D. I guess that 1000 is a nice round number.

Besides fish for dinner several time a week, I go through about a pound of Ahi poke..........hopefully that is a good source, because it is an addiction!

So a Thai basil beef with lots of fish sauce is health food! I knew it.

"In summer, among patients with stable coronary artery disease, there was an inverse relationship between baseline blood levels of marine omega-3 fatty acids and the rate of telomere shortening over five years ... These findings raise the possibility that omega-3 fatty acids may protect against cellular ageing in patients with coronary heart disease."

The Guardian article mentions summer. Might there be a vitamin D link or am I grasping with that?

I don't know, SOL the rest of the year?

"I have capsules with 1000mg of fish oil and 1000IU of vitamin D. I guess that 1000 is a nice round number."

Don't know for the fish oil, but for the vit. D, 1000IU is probably too low. I was taking 1000/day, upped it to 2000/day, and had a blood test done after being on the increased dosage for a month, and my blood lever was STILL low, so I have upped it to 4000. Need to get another blood test done next time I have occasion to visit my doctor.

I have noticed a MAJOR difference in my vulnerability to viruses. I used to have 4-6 colds every winter. Thus far, I have had ONE since upping the vit. D.

Fish Oil can raise cholesterol levels. To prevent an increase in LDL-C cholesterol, take a garlic supplement.

Does flaxseed oil (also contains lots of omega-3 fatty acids) give you heartburn? It might be a better alternative.

If you go by Dr. Cannell then vitamin D, fish oil, vitamin K2 and...whatever...go together.
